Turn a photo into black and white

Many people like to turn photos into black and white photos. But are all photos good for black and white? Today I'm going to tell you what kind of photos is suitable for black and white, and how to turn them into black and white.

What photos are suitable for black and white?

In order to convert a colored photo into black and white, the following conditions must be met: when the shadow occupies the majority of the picture, there are a lot of disturbing elements in the picture, the main texture should be displayed, negative space exists in the picture, and the mood of the picture should be displayed. Only if your photos meet these criteria will you be able to convert your photos to black and white, which will have a better effect. Otherwise, it will backfire.

Second, how to turn photos into black and white?

Here are some common Photoshop methods for turning black, white and gray photos.

Method 1:

Decolorize :(CTRL +shift+U) image menu -- adjustments -- decolorize (no adjustment layer)

Method 2:

Hue saturation (Ctrl+U) image menu - adjust - hue/saturation (with adjustment layer) desaturate.

Method 3:

Black and white (Ctrl+shift+B) image menu -- adjust -- black and white (with adjustment layer) after adding the black and white command, the screen will be automatically analyzed to set the luminous intensity of the color, and the left and right color slider will increase and decrease the luminous intensity of the color value in the screen.

Method 4:

Channel: enter the channel panel, select A monochrome channel, Ctrl+A select all, Ctrl+ c copy. Click the RGB blend channel again, go back to the layers palette, create a new transparent layer, CTRL +V paste it.

Method 5:

Gradient map, image menu - adjust - gradient map (with adjustment layer) gradient set to black to white color gradient.

Methods 6:

Channel mixer: image menu - adjust - channel mixer (with adjustment layer) check monochrome, output channel as long as gray, sliding the color value can adjust the intensity of the color value.

Methods 7:

Gray-scale mode: image menu -- gray-scale mode -- gray-scale mode converts RGB mode to gray-scale mode.

Methods 8:

Lab mode: because Lab mode is composed of two color channels and one brightness channel, we hide or delete the two color channels and only display the brightness channel, the image will become black and white image, and the gray image using the brightness channel will be particularly bright. (Note that when the two color channels are hidden, when the image mode is changed to RGB mode for operation, it is still a color image)

Conclusion: the reason why a photo should be processed into black and white is that I want to emphasize what I want to emphasize and hide what I want to hide through black and white. Instead of turning a photo into black and white just because you think black and white is cool
