My dear Jeff ... tinkering with photos is a broad topic and huge area where there's easy to drown .. as a pure hobbyist and mostly landscape photographer I commit this part of the photography in very calm and steady pace and still yet I am not sure if I hate it or if I like it ... problem here is, that once you get into it a bit you see how huge area is that and it's easy to find yourself caught 50:50% or worse hooked up on it so basically I try to be quick, effective and to do a minimal changes ... this is my trade off now so I feel that like for example my tennis career .. I love playing tennis but I know that I will never become a pro-player ... same with photo editing, no matter that's "soft" skill .. why do I say that ? I do say that because in past I've put much more importance in it and in reality it was taking me away from photography, it sucked my will and volition like some blood sucking vampire, it sat me in the front of computer rather than send me out with camera ... it's dangerous stuff, at least for me ...
