I attended a seminar on action photography last week and was made aware of the power of Instagram. Earlier I have hesitated to join and have not seen the value in it for me. But now I see the potential in it and will post a new picture daily and showcase some of my images taken on both DSLR and iPhone. I do not use filters on my cameras or in post, I mostly only do adjustments to the curves. I believe you still can do most of the work in camera with experience and good preparation.
