The "Photo Filter/photo Filter" command in PS CS is detailed

Filter | Source: 5D Multimedia

This is an important image adjustment command related to photography.

There is no one on the internet that can speak clearly or understand this order. Must be I have not found the reason, anyway I found none of you to explain, give a small example.

To understand, I first thought of the PS CS from the help document. I use the Chinese version of the PS, help document no translation over, looking at English I dare not so determined. To the group of QQ friends to come to the Chinese help description. Thanks QQ friend: Like a dog sharp diffuse, Leng, Aixinjueluo small basin:)
The Chinese version of this order is called "Photo filter", the English version is called "Photo filter", and my Chinese version is called "Picture filter".

Let's take a look at what the PS CS Self help document says, which helps to understand this command.

The following is a description of the command in the Chinese help document (with the command-related text, I added English, convenient to use the English version of PS friends to read), please be sure to read it carefully, which for our future explanation is very important:

--------------------------------------------
Using the photo filter/photo filter command

The photo filter/photo Filter command mimics the following methods: Color filters in front of the camera lens to adjust the color balance and color temperature of the light transmitted through the lens, exposing the film. The photo filter/photo Filter command also allows you to select a preset color to apply hue adjustment to the image. If you want to apply a custom color adjustment, the photo filter/photo Filter command allows you to specify a color (that is, a custom filter color) using the Adobe color picker.

The original image and the 60% concentration of the application of the warm filter (81)

Change the color balance using the photo filter/photo filter command:

1. Perform one of the following actions:
* Choose image/image > Adjust/adjustments > Photo Filter/photo filter.
* Select "Layer/layer" > "New Adjustment layer/new adjustment Layer" > "Photo filter/photo filter". Click OK/OK in the new Layer/new Layer dialog box.

2. To select a filter color, in the Photo Filter/photo Filter dialog box, do one of the following:
Select the filter/filter option and choose one of the following presets from the Filter/filter menu:

/warming Filter (85) and/cooling filter (80) for warm-tuned filters:
These filters are the color conversion filters used to adjust the white balance in the image. If the image is taken with a lower color temperature light (yellowish), the/cooling filter (80) makes the image more blue to compensate for lower color temperature ambient light.
Conversely, if the photo was taken with a higher color temperature (micro-blue), the/warming filter (85) would make the color of the image warmer to compensate for the high color temperature of the ambient light.

The warming filter (81) and the Cold tune filter (/warming filter) (81) and Cooling filter (82):
These filters are light balance filters that are suitable for minor adjustments to the color quality of the image.
Warm tune filter (Bayi)/warming Filter (81) to make the image warm (yellowing),
Cold-tuned Filter (/cooling) filter (82) causes the image to become cold (blue).

Individual colors

Applies hue adjustment to the image, based on the selected color preset. The color you choose depends on how you use the Photo filter/photo filter command. If your photo has a colored scar, you can choose the complementary color to be in and the color mark, and you can also apply colors for special colors or enhancements.
For example, the "Underwater/underwater" color simulates a slightly greenish blue color mark produced when taken underwater.

Select the Color/color option, click the color swatch, and use the Adobe color picker to specify a color for the custom colors filter. You can store a custom color in the Swatches palette by clicking the new Swatch/new Swatch button for future use.

Be sure to select Preview/preview to browse the results of using the color filter.

If you do not want to darken the image by adding a color filter, make sure the Retain Brightness option is selected.

3. To adjust the number of colors applied to an image, use the Concentration/density slider or enter a percentage in the Concentration/density check box. The greater the "concentration/density", the greater the color adjustment applied.

4. Click "Good/ok".

Oh, these professional nouns, is not to see you cloud mountain fog around. Unless you're a photography enthusiast, you don't know the jargon. These are not understood, then how do you use this PS command to process the image? Isn't that a random use?

Don't worry, everyone, we'll do the same.

Before you solve this, please continue to see my exclusive explanation below.

Anyone who has ever played a traditional camera should be aware and understand that a photographer often has a color temperature (what is the color temperature?). I told you not to hurry! To put it simply, the picture is blue, the color temperature is high, the photo is red, the color temperature is low. Control always feel uneasy and headache. All kinds of light color temperature value! Calculate the color temperature value! When and where to use what type of film! It's always a pleasure to be photographed.

Now is the era of digital, digital technology let us once again be liberated. Photoshop CS version of the function of the update, but also to the photography enthusiasts once again intimate care. The "Photo Filter/photo Filter" command, more highlighting PS to the photographer later photo processing convenient and quick!

When we use the traditional camera to shoot the scenery, if we find the scenery colorPartial warming, we'll add a slice of the cameraKodak Ryden 82nd Cold Color Rise temperature compensation filter, to adjust it slightly, or to useKodak Ryden 80th Cold hue rise color temperature conversion filterConverted over.

If we find that the color of the scenery is cold, we will add a piece to the camera lensKodak Ryden 81st warm down color temperature compensation filter, to adjust it slightly, or to useKodak Ryden # 85th warm down color temperature conversion filterConverted over.

If we feel that there will be a slight color deviation in the scene, we will add aColor Compensation Filter, to adjust the small amplitude.

(Note: Color temperature filters are divided into color temperature conversion filters and color temperature compensation filters.) Color temperature filters and color compensation filters are not a concept Oh! ）

The PS CS new "Photo Filter/photo Filter" command is equal to the color temperature filter and color compensation filter in traditional photography. You can also customize the color compensation filter. You don't have to pay for these camera accessories! Save it! Ha ha...

How, I such an explanation, everyone should be clear!

Clear is clear, but how to use it specifically?

What does the argument in this command dialog box mean?

Which one do I want to choose to be right!?

OK, please listen to me one by one!

In PS, open the image you want to process, select the "Photo Filter/photo Filter" command, pop-up its dialog box. There are very few adjustment parameters in the dialog box Oh! As we know from the above explanation, these parameters are the same as the usage of traditional photographic filters, and are relative.

We clicked "Filter/filter" to the right Drop-down list and popped up a total of filters.

Convenient for everyone to read, made in Chinese and English control form.

The top four are the Kodak Ryden color temperature filters, and the last 14 are color compensation filters.

Before we talk about these two filters, we need to find out a professional noun: color temperature.
(Start talking about theory, and everyone has to be prepared for it.) It will be more difficult to understand and I will try to make it clear and interesting. The theory of color temperature is very important to photography, you do not understand, you have no understanding of PS in the photo filter command. So please watch patiently and you will reap a lot! : s)

The temperature of color, colour and colors.

What the? Color and temperature? Of course. Color also has temperature.

What is the color temperature?
The color Wen Quan is called Kelvin temperature, the unit of color temperature is k, namely Kelvin, Kelvin.

And we Chinese usually use the Celsius temperature, and the American use of Fahrenheit, as the temperature is a unit of measurement. But the color temperature is a description of the temperature of the light.

0 Kelvin is equivalent to 459.67 Fahrenheit temperature.

namely the so-calledColor Temperature------is to quantifyKelvin TemperatureSaidColor。

In order to facilitate the comparison of different spectral components, the selection, adjustment of control conditions and chroma calculation in some applications, usually using color Win Lai to express the spectral characteristics of illumination light source.
The method used to calculate the color composition of light is the 19th century by the British physicistLord KelvinCreated, he worked out a set of color temperature calculations, which are based on the wavelength emitted by a blackbody radiator.
The relationship between the color and Kelvin temperature originates from the blackbody radiation theory, which heats the blackbody (the object that absorbs all visible light) until it glows (like heating iron),The color that is present at different temperatures is color temperature。

The black body from absolute zero (15 degrees Celsius minus 273 points, reminds me of the Holy Warrior Glacier) began to warm up, the temperature per elevation was once called 1 Kelvin (with the letter K) when the temperature rises to a certain extent, the blackbody radiation from visible light, Its spectral composition as well as the feeling of the person will change correspondingly as the temperature increases. As a result, the blackbody radiation of a certain shade of the temperature as the emission of the same light source color temperature.

When theBlack ObjectWhen heated, the heat is equal to 500-550 degrees Celsius and becomesDark red, if you continue to heat up to 105,011,150 degrees Celsius, it will becomeYellowAnd then white, and finally it becomesBlue。

WhenBlack ObjectWhen the temperature reaches 3200 kelvin, it will emitRed Light, the tungsten filament of the incandescent lamp that we normally use will emit this kind of light. When the temperature rises to 5500 Kelvin, the black object will pale light, which is equivalent to the midday sun light, usually the faint light we see at dawn.Blu-rayThe intensity of light emitted from a black object in the 12000 Kelvin is similar.

The color composition of the light source corresponds to the thermal temperature of the blackbody. But the color temperature is expressed in Kelvin (K) color temperature units, not in Celsius units.

In the process of iron, the black metal gradually turns red in the stove, which is the best example of blackbody theory.
Usually the tungsten filament in the bulb we use is equivalent to this blackbody.
The color temperature calculation method is based on the above principle, using K to express the temperature of light emitted by the heating tungsten wire.
According to this principle, any light color temperature is the equivalent of the above blackbody powder to emit the same color when the "temperature".

So now we're going to follow one of the Kelvin theories, which we can deduce:

The higher the temperature,BlueThe more ingredients, the image will be biasedBlue；
The lower the temperature,RedThe more ingredients, the image will be biasedRed。

Through the above explanation, I think we should understand and understand the concept of color temperature.

So what does color temperature have to do with photography? What does this have to do with the photo filter we're talking about?

I remind you that photography is the art of dealing with light and shadow, and the color temperature is the symbol of spectral characteristics of light source! So in the field of photography, light sources are defined according to their color temperature. So the two are combined. Became a professional term for photography.

Color is actually a psychological physical role, all the color impression is due to the time of the continuous spectrum in the eyes of the reaction, so the color temperature is only used to represent the visual impression of colors.

　　 because light is emitted from light sources at different temperatures, the same color behaves differently in different environments., which increases the number of factors that we have to consider in the camera's filming process.

For traditional cameras, it is possible to choose a different film (color film design, is generally based on a true record of a specific color temperature of the light source lighting, divided into 5500K daylight, 3400K strong lighting and 3200K tungsten type of variety. Plus some filters to adjust the color temperature.

Therefore, we must know how to use the same color temperature with the same colour film, will be accurate color reproduction. If the color temperature of the light source is not balanced with the color temperature of the film, it depends onFiltersTo promote or reduce the color temperature of the light source, so that with the film fixed color temperature matching, will have accurate color reproduction.

In a digital camera, there is no film, so how to deal with the problem of color temperature?
And for digital cameras, this is an easy problem to solve.
It's going to refer to the proper terminology of digital cameras.White balance"Up. The concept of white balance is not in the traditional camera. Because the traditional film photosensitive has been fixed, only the CCD in the photosensitive element only, is generally automatic control, but as a professional with the best manual white balance control function, so that the color of the scene more accurately reproduce.

CalledWhite balanceIs the camera's restoration of white objects. When we look at this colorful world with our eyes, in different light, the feeling of the same color is basically the same, such as in the morning sunrise, we look at a white object, feel it is white, and we in the dim light of the night, see the White object, feel it is still white. This is because we humans from the birth of the process, the human brain has been different light objects in color reduction has adaptability.
However, as a camera, can not be the adaptability of the human eye, in different light, due to the unbalanced CCD output, resulting in the camera color reduction distortion: specific to the shooting of white objects when the performance is not blue, is biased red, resulting in the entire image color distortion.

Therefore, if the light of the irradiated object changes, then the reflected color will also change, and this change reflected in the camera, it will produce in different light color reduction of different phenomena.

　　 for the digital camera is the white balance of the problem is the color temperature problem, the traditional camera for the color temperature of the problem is the problem of film and filter.

Oh, my God, do you know what I said?

So the question is, what if we take a picture that is biased?

We have already understood the concept of color temperature through the above explanation, then the simplest method of recognition is: according to the color temperature theory, partialRedThat meansLow Color TemperaturePartialBlueThatHigh Color Temperature。

Way to solve:

1, adjust the digital camera temperature control switch correctly or set the corresponding light switch on the digital camera correctly, adjust the white balance correctly.
2, for the traditional camera, is the correct choice of film, and add filters.

What, you don't have a camera but you want to do it with a filter?

Then use the PS command to add filters to the traditional camera or set a white balance for your digital camera!

Well, through the above instructions, we have fully understood what is the color temperature?
Let's look at what the camera's color temperature filter and color compensation filter are.

Color Temperature Filter

The color temperature filter is specifically designed to adjust the color temperature of the lens into the light, to meet the requirements of colour colors.
The color temperature filter is used to adjust the color temperature in the light source. According to the above color temperature theory, we already know that indoor lighting and outdoor sunshine color temperature is not the same, even the morning, dusk light color Mild Noon light temperature is also different. If you can use the appropriate color temperature filter to correct the color temperature, you can get the ideal photo effect.


The color temperature filter has "OrangeandBlue"Two big series.
　　 OrangeSeries forLower Color Temperature, namelywarm down Color temperature compensation filter；
　　 BlueSeries forIncrease Color Temperature, namelyCold color Rise Color temperature compensation filter。

In the color temperature filter, according to the magnitude of the temperature of its rise and fall, can be divided into "Color temperature conversion filter" and "Color temperature compensation filter."

1. Color Temperature Conversion Filter:
The color temperature filter, which can greatly lift the color temperature, is designed for "daylight-type film" to be used under light and "light film" in daylight.
(Sun-shaped film, suitable for use in sunlight or under the flash of a color film, if used under tungsten, the photo will be marked with orange tone.) Light film, suitable for use under the tungsten color film, if in daylight or balance in the light of daylight, the photo will have a clear blue tone. )

The "Ryden" 80A, 80B, 85, 85B in the Kodak Ryden Color temperature filter are four common color temperature conversion filters. (A, B, C, d refers to the concentration of the color of the filter.) ）

Kodak Ryden # 85th warm down Color temperature conversion filter:
85 Series is divided into a, B, C, color temperature conversion filter. 85B can reduce the color temperature from 5500K to 3200K. The mirror is amber and is suitable for using light film in daylight.

Kodak Ryden 80th Cold hue rise Color temperature conversion filter:
The Mirror color temperature conversion filter, divided into a, B, C, Ryden 80A can be the color temperature from 3200K to 5500K, the use of the mirror can be used for solar-type film artificial light.
(1) Ryden 80A: Used for solar-type film in 3200K (tungsten) light shooting. (The aperture needs to increase 2 gear)

(2) "Ryden" 80B: for solar-type film in the 3400K (Photo-strong light) of the light shooting. (The aperture needs to increase 2 gear)

(3) "Ryden" 85B: A light film (b-type) for balancing the color temperature to 3200K is photographed under 5500K daylight or electronic flash. (The aperture needs to increase 2/3 gear)

(4) "Ryden" 85: Light film (Type a) for balancing the color temperature to 3400K is photographed in 5500K daylight or electronic flash. (The aperture needs to increase 2/3 gear)


2. Color Temperature Compensation filter: Refers to only a small amount of color temperature of the color temperature filter, for the balance of color temperature.
The "81 series" and "82 series" in the Kodak Ryden color temperature filter belong to the color temperature compensation filter.

Kodak Ryden 81st warm down Color temperature compensation filter:
"81 Series" for the Warm color drop color temperature compensation filter, it is a red series of filters, can slightly reduce the temperature of the light source. Ryden 81 is a warm dimming balance filter, points A, B, C, the color of the light of the amber, you can slightly adjust the picture in the blue trend, in order to real color restoration. In actual use, to Ryden 81C for more.

81 Series Color Temperature compensation filter in light tooBlue, which is used when the color temperature is too high. is used against blue light to reduce the color temperature.

"Ryden" 81C: for solar-type film in rainy days (temperature of 6800K or so) shooting. (The aperture needs to increase 1/3 gear)

Kodak Ryden 82nd Cold Color Rise temperature compensation filter:
The "82 Series" is a filter for the cold color rise temperature compensation filter, which is a micro Blue series. Can slightly increase the temperature of the light source. The mirror is a color balance filter. Light blue, divided into a, B, C, this type of filter is characterized by a small change in color temperature, much for the color temperature and film balance color temperature generally consistent with the premise of minor adjustments.

"Ryden" 82C: for solar-type film in the early morning or evening shooting. (The aperture needs to increase 2/3 gear)

82 Series Color temperature compensation filter in light tooRed, which is used when the color temperature is too low. is used against red light to improve the color temperature.

82 series filters are less available than the 81 series.
In fact, the experience of many photographers is to try to increase the color temperature rather than reduce the color temperature.
Using a light yellow filter to shoot the most common sunset phenomenon will have a very spectacular effect.

According to the above explanation Kodak Ryden Color Temperature filter also has a, B, C, D points. is the command in this PS able to meet the requirements? Of course. The friend who has this question explained that you still did not understand Ryden color temperature filter. The classification of A, B, C, D is just the amount of concentration. In the Photo Filter dialog box, there is the "concentration" option, the default is 25%, we move the slider concentration will naturally come out.
It's as simple as that. It's a, B, C, D.

Color compensation Filter

The color compensation filter is also a common filter that outdoor photographers often use to shoot color slides. It adjusts and controls the color of the color film to make the appropriate color compensation for the photograph. Although the color compensation filter is not as compelling as other filters, it is important.

Color compensation filters generally include:

　　Red, Orange, yellow, green, cyan Cyan, blue, yellow Purple Violet,
　　Magenta Magenta, brownish sepia, crimson deepred, dark blue deepblue, dark green deep Emerald, deep yellow deep yellow, underwater (green) underwater.

It is mainly used to correct other color deviations, and is used to accurately adjust the slight color deviation in the photo. All we need to know is the color compensation filter and Black-and-white photography used in the red Mirror, Huang, Orange mirror, green mirror, yellow-green mirror, Blue Mirror, that is, contrast filter (also known as contrast filter) and color temperature filters are different.
This "photo filter" in the Photoshop CS refers to color photography, so the black photography is not explained.

Color compensation filter to adjust the amplitude of small, color temperature control filter to adjust the amplitude of the larger.

Finally came to the most exciting example to explain the section. If you understand the truth, you can do everything well.

We will explain the use of "Photo filter/photo Filter" in the following aspects of the actual application process.

This command is used to correct some color deviations caused by the improper scanning, film flushing and white balance settings.
Used to restore the true color of a photograph.
Used to adjust the slight color deviation in the photo.
Used to emphasize the effect, highlight the theme, and render the atmosphere.

Below I give a few of the most common examples for you to refer to.

If the whole picture is blue:

One is caused by high color temperature. Cloudy or thin cloud cover day weather, natural light color temperature up to 7000-12000k, no use color temperature filter;
The second is surrounded by a dense tree-lined or large blue advertising, curtain wall and other environmental reflection of the impact of light.
The solution is to use a 85 or 81 drop color temperature filter at the time of filming, such as a blue ambient light reflected nearby, and move as far as possible to the open space.
If there is no way, use the "Photo filter/photo filter" to deal with it!

If the image color is blue, then you can use warming Filter (81) To do color temperature compensation, to reduce the color temperature, or use warming Filter (85) To do color temperature conversion, to convert color temperature. However, note that when using the warm filter to correct the blue deviation, because the brightness signal has a certain loss, so the brightness and contrast should be adjusted higher, the effect will be better.

Because the sky environment temperature is higher, so take out the picture tone blue.

Warming Filter (81) To do color temperature compensation, to reduce color temperature, concentration of 40% or so, and then adjust the contrast. Correct the color temperature after the image effect.

If the whole picture is red-orange:

1, daylight color film used in the light, and did not use the Ryden 80B color temperature conversion filter;

2, morning and evening sunshine color temperature only 3200K, low color temperature caused by orange red tone, Sunset color Winyo is 3000K, sunrise or sunset before the 20 minutes to 120 minutes of direct sunlight is 2200K to 4700K, no use of 80 or 82 cold color rise color temperature filter.

3, surrounded by a huge red advertising or red buildings, reflecting red light.

Workaround:
If there is a red-orange ambient light reflection, as far as possible to move to other venues shooting.
If there is no way, later use "Photo filter/photo filter" to deal with it!
If the image color is red, then you can use warming Filter (82) To do color temperature compensation, to enhance the color temperature, or use warming filter (80) To do color temperature conversion, to convert color temperature. However, note that when using the cold color rise color filter to correct the red deviation, because the brightness signal has a certain loss, so the brightness and contrast should be adjusted higher, the effect will be better.

Photo color is warm, the color temperature is low.

With the 80 or 82 cold color rise temperature filter, I selected the cooling filter (82), concentration 25%. The revised photos bring some blue tones and enrich the picture. The theme is more prominent.

People are so strange. Sometimes the real thing is not what we want. The subject of exaggeration emphasizes the art instead. So is photography. The following example is the case. We're going to turn it into the sunset at sunset. The biggest problem with this picture is that there is no one-step decline in the sunset atmosphere, the screen less than a bit of appeal.

I used warming Filter (85) with a concentration of 80%. After the adjustment, the effect came out immediately. Is it a little bit like the sunset?

The color is too light, less the atmosphere of the sunset.

After adjusting, the color effect is enhanced. emphasized the subject. It's more contagious.

Color compensation filters are often used to accurately adjust the slight color deviation in a photo, although the range of adjustments is small.
This is the case with the star photo below. The original image is too bright, color is too light, less sea breeze blowing, like the Aegean romantic aroma atmosphere.

Let's add a cyan filter in a color compensation filter with a concentration of 25%.
After adjusting the out, the screen slightly magenta blue, the breath of the wind immediately greeted. People relaxed and happy, intoxicated among them. The subject was immediately underlined.

The original is too bright, the color is too light. Color temperature on the high side. The theme of the sea breeze is not sudden.

Slightly lower the color temperature adjustment, the atmosphere of the sea breeze immediately present. The subject naturally highlights itself.

The above example I used is a new adjustment layer, so that more convenient to modify, but also have a mask can be selected, more convenient. Any time can not be satisfied with the new changes in the place.

Well, the channel is the face of the theory and examples to explain, I want to love photography friend must have some harvest.

Whether we install the Kodak Ryden 80th Color temperature filter in front of the camera lens, or use the cooling filter (80) in the "Photo filter/photo filter" in PS CS, we end up doing exactly the same thing, The color temperature will increase to let the photo restore the true color or make some special effects.

This time the command does not understand the friend, should understand it!
