Black and white photography is all about texture. It’s about the subtlety of shades and shading.
By all means – shoot in color. Then convert the shot afterwards in your favorite photo editing software. The color actually helps define the range of shading in the b&w result.
After some practice, you will see that it’s not as easy as it sounds. Certain color shots make great b&w. Others don’t. You’ll soon learn which is which- and why.
It’s not stepping back into yesteryear to do this, you know. It’s really seeing your world in a whole new light.
Learn to see in black and white. It’s fun trying. And even if black and white is not your cup of tea, it will make you a better photographer.
