I really love colours in photography.
I also love colour in portraits like this one:
But sometimes I just feel like doing black and white. Sometimes it just feels right. Sometimes black and white is the only way to go. Like with this pic:
It really didn’t look right in colour. And since I’m shooting RAW on my camera, I can pretty much tweak a picture in anyway I want to using Adobe’s Creative Cloud (Photoshop or Lightroom) or free apps like Snapseed on mobile (I actually used Snapseed on this one).
I love black and white because of it’s purity. I would (almost) never use it for landscapes though, as I love nature in all it’s colourful, faceted beauty. Black and white just can’t keep up with that. But for portraits it works just fine.
