Yet somehow you find time to both eat AND sleep, every single day, without ever saying such things as "eating takes away valuable sleeping time". There is plenty of time to do everything you need to do. I shoot first and PP later, when there is no shooting. Simple. Heck, you're here typing in an internet forum when you could be out shooting!
I appreciate the analysis of my free time, but I've worked it out pretty well myself and know what time I have to do whatever I want and need to in a day...and PP just isn't one of those things I feel like doing. I like many other things - photography is one - but when I have additional free time, there are hundreds of things I'd rather spend it doing than spending it in front of a computer. That's just me. I don't judge anyone else's free time pursuits.
Hoo boy, 8 hours of processing. I've spent that much time on one single shot. And still have time to work long hours, do chores, visit family and friends, play tennis, eat, sleep, etc, and still have never sacrificed shooting for editing.
Yet 8 hours spent on a single shot post processing is YOUR choice for that time - I don't care how much time I have to fit in other things in my day, I simply do not want to spend 8 hours in front of a computer working on post processing - having nothing to do with how much free time I have to do other things in my day. It's about what you enjoy. You enjoy post processing and sitting with a computer, I don't. So I'd rather take that 8 hours and spend it doing something else...heck, even doing nothing - take a nap, read a book, vegetate in my pool. People should all do what they enjoy.
I think what this comes down to is how much effort you want to put into each shot. Some are more anal about every detail of their image being perfect and others are not, and use the "I could be out shooting" story as an excuse to not work at improving their PP.
I think it all comes down to people judging how others spend their time, and not being open to the possibility that not everyone in the world thinks the way they do. Because YOU would feel that a person who doesn't like post processing is making an excuse, or has no PP skills, don't assume that's everyone else's situation. Note the difference: I never said anyone else should avoid processing, or that time spent post processing is futile, worthless, or a waste. I never judged anyone else for choosing to post process their photos. I simply stated that I don't like to do it as much, and therefore don't, simply because it's not that engaging to me. Remember this came up because the OP asked if EVERY shot, and EVERY photographer, post processes...and I simply replied that I am a photographer, and I often choose not to...just as others chimed in that they do. On the other hand, responses to me were much more judgmental: I am making excuses, I am incapable of post processing with skill or have inferior skill and avoid it, etc. Sounds quite judgmental and closed-minded to me. I know how to post process perfectly well - been doing it for 12 years. I shoot RAW+JPG when I'm hired for a shoot, and if I need to I can process a RAW shot to perfection if the JPG was not as good. I have 3 different post processing editors and 5 plugins. Simply put, my PP skills don't need any improvement. I simply don't enjoy doing it like you do. I do it if I NEED to, or HAVE to, but when shooting for only myself with my photography hobby, I don't have that craving need or desire to do it - I just want to enjoy the shot that comes out of the camera, that I took, using my settings and skill. When I'm shooting someone else's photos, for hire or for an event, then I need to consider THEIR needs and wants, and will keep the post processing option open as they are the ones that need to be pleased - a flubbed shot or dull shot won't go over well. When I'm shooting for myself, for pleasure, a flubbed shot is simply deleted - and I go try again...I have the luxury of time and no one else to answer to, so I can spend my time however I enjoy doing so. That's shooting, not post processing for me. If I'm done shooting and have time to do something else, I'll read a book, paint a painting, build a model, do some home renovation, work on my car, or do something else I enjoy. Why on earth would I do something I don't enjoy doing, no matter how much time I have on my hands? That would be like saying "hey, I have free time, so there's no reason I can't sit here and poke sewing needles in my eye!". I wouldn't enjoy that, so I wouldn't do that - even though I'm quite capable of sticking sewing needles in my eye, as well as the next man. Same goes for post processing.
If you enjoy post processing, wonderful. Accept that some don't enjoy it as much - not due to inability, but due to non-interest. I'm sure there's something out there in the world that you don't enjoy doing, yet have the capability and skill to do it. You don't do it, because you don't ENJOY doing it...it doesn't mean you are incapable of doing it.
