Btw I have as much admiration for people who can get an in camera jpg fully right the first time w/o any post processing (like Mangelson) as I have for people who can pre-visualise their PP process, shoot a picture and create their vision afterwards by using the PP tools. If I could achieve either one I'd be very happy, allthough I would personally more err to the latter.
I agree, but I'd go further even a little further with that and say that if you're NOT pre-visualizing your post during a shoot, you're not really at the highest level of photography,
even if your plan for post is to not do any. Using an in camera JPEG or even a Polaroid is still a plan, and you still have to anticipate the consequences of that plan and shoot accordingly.
I'll be brave and throw some of
my work out there as an example. Shooting into windows often compresses the dynamic range of a scene, especially if the contrast in the scene isn't high to begin with. A lot of those images showed up on the camera histogram as a single spike of luminance. So what I do is, push that spike as far to the right as possible, and then in post I work to spread that information out into a proper distribution of tones. Without pushing the tones back down where they belong, the images don't look like hardly anything at all-- no saturation, no detail, just a big blurry high-key wash. But let's say I'm shooting JPEG instead. If that was the case, I wouldn't try to expose all the way to the right, because JPEGs don't react the same way as RAWs when you try to pull more out of them. I'd expose as close to the final product as possible (at the shots would suck, but that's neither here nor there.)
Now, none of this is to diminish the importance of getting the right exposure while you're shooting. Just the opposite-- I don't want to spend all my time polishing turds in post, and I doubt there's many who do. Shot discipline, to borrow a term from Thom Hogan (I think), is critically important to top-quality photography. What I'm trying to get at though, is that the relationship between shooting and post is highly intertwined, and in fact, the intended post-processes actually
dictates what the proper capture is. To put this in real terms: hand the world's most technically skilled shooter a film body, tell him it's loaded with T-Max 3200, and actually load it with Velvia 50. See how good the shots come out.
Ok, so what's my point with all this then? It's that you can't separate capture from post. They're just two parts of the same processes, the heart and the brain. One can't exist without the other. Together, they form a functioning body, and we call that body Photography.
