10 ways to make black and white photos in Photoshop

When it comes to black and white, we will come up with a lot of classic masterpieces from history. Yes, the invention of photography, like a movie, is a black-and-white thing,

Many pioneers, leaving countless works of the most popular. Despite today's technology rapid, anyone can pick up a camera and take a colorful picture,

But Black-and-white photography is still standing, by many color friends fanatical love, why? Because black and white have taste!

The world is color, and black-and-white photography is the realistic color of the world into an abstract black, white, gray-tone, thousands of colors and layers are simple monotonous gray-scale performance incisively and vividly,

Is this not an exciting magic?!

Buddha said: Color is empty, empty is color. We use photography to understand, this is the mood.

Colorful colors sometimes interfere with our vision, disturb our emotions, we empty them to zero, the world suddenly become quiet, peaceful, we can better appreciate the elements in the painting,

A better taste of the subject in the painting does not prevent us from imagining and judging the color, because we have an objective perception of the world, as we know that the sky is blue and the leaves are green.

Black and white tone free of the real world, but also with a unique means to express the real world, giving people more imagination and thinking space, like, meditation like ...

Black-and-white photography is widely used in the humanities, portrait, scenery and other fields, especially the humanities, many color friends like to use black and white tone to express,

Perhaps this is a kind of imperceptible aesthetic bar, Black-and-white humanities seems to be more people feel cordial, true, and simple.

"Analog Black-and-white and digital black and white"

From the silver-salt era of color friends, will probably agree: the true meaning of the traditional black-and-white photography is on the Black-and-white film, its best carrier is black-and-white photographic paper.

What we share on the internet is digital black and white, even though you scanned Black-and-white photos or negatives because they were eventually "0-255″" by the numbers,

We used to call it "pseudo black and white." True black and white belong to the simulation, pseudo black and white belong to the digital, just like the audio industry in the black vinyl record and CD-ROM,

The former is the audio signal engraved on the Bakelite in the form of pits, through the stylus and the mechanical contact of the pit to read the signal;

The CD is to convert the audio signal to 0 and 1 of the digital form burned on the disc to laser laser non-contact reading, the taste is very different.

What's the difference? It's probably like the different flavors of black tea and white teas that are said in the tea ceremony. The taste of Black-and-white photos is as mellow as puer, Chenxiang and old!

"10 ways to get digital black and white"

In contrast to color photography, I think black-and-white photography More emphasis on the late, whether it is black or digital photos, from the original data must be through a variety of late means

For two of times to create Black-and-white images of different tone effects. Whether it's a traditional black-and-white darkroom or a modern digital darkroom, it can be fun.

Here are 10 ways I've learned to get digital black and white.

"Hard means":

(1) scan/remake photo or direct scan film

This is the film's color network to share the way, scanning/remake of color or black and white, but the film scanned into a digital, it became a "false black and white", if well-equipped,

Can still reflect the characteristics of the film.

(2) Digital camera directly in black and white mode shooting

Many digital cameras are equipped with Black-and-white shooting mode, I believe that its internal computing methods and software similar to the late, so I was rarely used in this mode shooting,

Only used when I decided that the theme must be performed in black and white. D80 Black and white mode is also equipped with a variety of filters, used to play black and white film machine color friends may be able to find a hint of intimacy on the digital machine.

"Soft means": (Take Photoshop CS3 for example)

(1) Turn gray mode

Method: Image-Pattern-grayscale

This is my most used method, very simple and practical, but also a lot of textbooks and experts recommend the use of the method, that it is the best black and white mode, you can get more pure black and white tone,

The algorithm is based on a certain proportion of RGB (red about 30%, green about 60%, blue about 10%) to show grayscale, and the human eye in the proportion of three pyramidal cells close.

The biggest advantage is that all the information is kept in gray space, but there are some disadvantages, that is, when a color channel has impurities or poor performance, can not be adjusted separately.

(2) Reduce the degree of saturation

Method: Image-Adjust-hue/saturation

This method is also very simple, the saturation slider to the left to 0 of OK.

But if it's all black and white, I won't use this method, only if you need local color or keep some color, because it has the advantage that it can be used for the original image of the color channel

Adjust the saturation separately. You can select a color in the Edit section of the dialog box.

(3) Lab Mode

Method: Image-Pattern-lab color

This method is a little special. First lab mode is represented by three channels, The L channel represents all the light intensity information, a channel represents green to PINKCO information, B channel represents blue to yellow information,

Use this mode to turn black and white in fact just use L channel, remove color channel, also equal to remove some impurities, get is more bright transparent black and white tone.

I think it's more appropriate to be used to show children and women's soft and toned themes.

(4) Adjust black and white

Methods: Image-adjustment-black and white

This is a versatile and easy-to-use method, you can adjust the original image of the color channel, you can set the "preset" filter effect, you can adjust the black after the "hue",

For PP plus monochrome, and can change the hue and saturation, just like the traditional black-and-white darkroom, in the potion to add colored powder, so that pp show color of the single tone.

(5) Go color

Method: Image-Adjust-go color

This method is also extremely simple, like turning grayscale, the mouse is OK. Go to color is to remove all the color, get black and white tone, feel and turn the gray scale almost,

I don't see any real difference on my computer, perhaps the algorithm is roughly the same.

(6) Gradient mapping

Methods: Image-adjustment-gradient mappings

This is also a good way to turn the black, like Gray, belong to the lossless black. To get a black and white tone, you must first set the foreground and background colors to black and white before adjusting.

Of course, its function is far more than that simple, click the dialog box in the "Grayscale mapping used gradient" can pop up a gradient editor, pull the slider can adjust the contrast and brightness,

You can also choose a different color gradient in the "Color label" column to get the color's single tone effect.

(7) Calculation method

Methods: Image-Calculation

This method is believed that very few people use, because its operability experiment is very strong, not easy to master the effect, will spend a lot of time. It is generated by a different blend of two channels

The new channel can calculate the combination of any two color channels to obtain different tone effects. Not recommended for use.

(8) Channel mixer

Image-Adjustment-channel mixer

This is also a very experimental method. It has several commonly used filters, the same principle as the traditional Black-and-white photography filter. If you do not want to use the filter, you can click on the bottom of the "monochrome",

After turning black, you can adjust the R, G, b three color channels respectively to achieve different effects. The constant slider adjusts the intensity of the screen.
