90% of the time I try to be as realistic as possible, so go for as pure of accuracy as possible: with exception made for increasing bokah/lens blur to accent subject.

I am just getting into accenting a single color for photographs: usually live concerts, but some candids in unique setting (like a boxer walking to the ring where I made everything BW except for the color red which matched his gloves and the posts of the ring)

I like bright colors and sharp edges. Always twist yellow, green and blue. In my opinion, pictures became more dynamic.

In b&w photos I prefer to twist shadows and to add more black spots.
