One mode is underestimated today – black and white.

As I have pointed out here before, black and white can make your images much more powerful by allowing the eye to concentrate on your subject – not on coloured objects.

This image works better in black and white:

Because in colour, the red chairs draw the eye towards them instantly. You do not see the forest for the trees:

So when your subject is not the colours in your scene, consider using black and white. When colours would distract, use black and white. When you want to convey a certain mood, use black and white.

And when you use black and white, convert afterward, in Lightroom. That way you can tune the relative brightness of colours – this is like using filters in the old days.

So by using the HSL control to tweak the red colour, you can, if you wish, make it look light like this, say:

Or dark like this:

And the same goes for all other colours.

All those reasons are why if you are not yet using B&W, you should start. Shoot RAW and do the conversion later. And have fun.
