This is going to be a thoroughly anecdotal, subjective informal survey. I'm going to go over some of my images and apply a colorful and whimsical bokeh effect to some of them. Is it your experience that DT even accepts these images and do they sell?
This is very general of course. The bokeh effect can look very "artsy" or very highly sytlized at times, depending on the subject matter. So I'm not sure if I'm even setting you up for a proper answer, but was just curious if I should even play around with the effect for the purpose of sales.
