Photoshop Tips Tutorial: Black and white photo color blending techniques

　　Color is empty, empty is color

when it comes to black and white, we will come up with a lot of classic masterpieces from history. Yes, the beginning of the invention of photography, like the film, is black and white, how many pioneers, and left countless works of the most popular. Although today's technology rapid, anyone can pick up the camera to take a colorful picture, but Black-and-white photography is still standing, by many color friends fanatical love, why? Because of the taste of black and white!

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 levels by the simple monotonous gray-scale performance is incisively and vividly, this is not an exciting magic it?! Buddha said: Color is empty, empty is color. We use photography to understand, this is the mood. Colorful colours 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 of the painting, better to understand the theme of the painting, but does not hinder our imagination and judgment of color, because we have an objective understanding of the world, As we know the sky is blue 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 performance, probably this is a kind of imperceptible aesthetic, black and white humanities seems 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″" and we used to call them "pseudo black-and-white." True black and white belong to analog, pseudo black and white belong to digital, just as the black vinyl disc in the audio world is the same as the CD disc, 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, and the CD is the audio signal into 0 and 1 of digital form to burn on the disc, The taste of the two is very different by the laser-less contact reading. 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!

　　Get digital black and white 10 big means

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 to two times to create a variety of different shades of black and white images. 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 playing film color network to share the way, scanning/remake color or Black-and-white, but the film after the scan into a digital, also became "false black and white", if well-equipped, or can 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 late, so I was rarely used in this mode of shooting, but I decided that the theme must be used in black and white to express the use. 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:

(1) Turn gray mode

Image-Mode-grayscale

That's the way I use it the most, very simple and practical, but also a lot of teaching materials and experts recommended the use of the method, that it is the best black and white mode, you can get more pure black and white, because its algorithm is based on a certain proportion of RGB (red about 30%, green about 60%, blue about 10%) to perform grayscale, The proportion of three pyramidal cells in the human eye is 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

Image-Adjust-hue/saturation

This method is also very simple, the saturation slider to the left to 0 of OK. However, if the whole picture is black and white, I will not use this method, only when the need for local color or retain some color, because it has the advantage of the original color channel can be adjusted respectively saturation. You can select a color in the Edit section of the dialog box.

(3) Lab Mode

Image-Pattern-lab color

This method is a little special. First, lab mode is represented by three channels, L channel represents all 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, at the same time also equal to removed some impurities, Get a brighter and more 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

Image-Adjustment-black and white

This is a versatile and easy to use method, the original color channel can be adjusted respectively, you can set a variety of filter effects in the preset, you can adjust the "hue" after turning black, add monochrome to PP, and can change hue and saturation, just like the traditional black-and-white darkroom, add colored powder in the potion, Let pp show the color of a single tone.

(5) Go color

Image-Adjust-go color

This method is also extremely simple, like turning grayscale, the mouse is OK. Go to color is to remove all colors, get black and white tone, feel and turn gray level, in my computer can not see what the real difference, probably the algorithm is roughly the same.

(6) Gradient mapping

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, but also in the "Color standard" column to choose a different color gradient, to obtain a color of the single tone effect.

(7) Calculation method

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 generates a new channel through a mixture of two channels, and 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 a filter, you can click on the bottom of the "monochrome", black, you can respectively R, G, b three color channels to adjust to achieve different effects. The constant slider adjusts the intensity of the screen.
