The question of whether to shoot street and travel photos in black or white or color is an eternal one that isn’t going to go away. But one of the interesting things about digital photography is that it lets you decide whether to process a photo in black and white or color after the photo has been taken. Unlike film photography, there’s no need to commit to one or the other until you open the photo in Lightroom.
But is that a mistake? I think it is because black and white photography and color photography are two different mediums. If you are working in color, then you need to pay attention to the colors in the scene and how to use them to create an interesting composition. But in black and white, you need to pay more attention to textures, contrasts, and shapes in order to create a strong composition.
That’s on top of the task of capturing the expressive moments that the best street and travel photos reveal.
There’s a lot to think about, and as black and white and color photography require different mindsets, it’s a good idea to make the decision about which you are going to shoot before you press the shutter button.
Having said that, it is also helpful to think about the following factors when you are processing photos. It may be that you were working in color, but realize afterward that a particular image would work very well in black and white. The same considerations apply, except that you have more time to think about it.
