Looking back at old images is good!
I never delete images (unless they are truly terrible, like i left the lens cap on etc...), and often go back to look through old shoots and trips. I find that as my style matures, and editing skills and software gets better, revisiting old images can bring a new result. Also, at the time of shooting, I choose a particular image or two that i like the best at the time... looking back I often pick other ones instead. Here is an example, this was part of a series of images i took of a leopard crossing, but this particular image never made my final cut at the time... now I think it is one of the best! What do you think? :)
Do you ever look back through your images long after shooting them? Do you agree with me? Let me know.
