One of the most popular subject in photography ? Black and white. Why ? Simply because it does not care about the colours. It focuses on what is important, shapes, lines, textures.
There are two ways to achieve a B&W photograph, either you shot in full colour mode or you chose to directly shoot in black and white. I don’t have any prefered option. But I must admit one thing, it is suprising how a picture, once turned in black and white, can reveal its full potential.
You can draw the attention easier. Making the eye focus on the lines and on the geometry of the picture.
