What I love in Open Camera is that I am able to turn off all extra post-processing (noise, yes please) and use my phone camera with full manual settings like it was a DSLR (with a really bad sensor). Only problems are clunky UI and general slowness of taking pictures, but you get used to it.

It's really unbeatable from a photographer / artist perspective, especially because I care a lot about imperfect gritty noisy looks and full control.
