Quote: My impression is that when an image is well exposed, the RAW is not necessary. You can get a little extra out, but not worth the effort imho.
The extra effort is vastly over-stated. Using Aperture, at the beginning of a sequence I use one of my presets, whichever one gets close. I just click down the list and pick the closest one. Then I make the final changes. Before I start the individual controls, if the number of changes is different from my normal presets, I save them as a preset. I use that preset for the rest of the pictures. Or if I don't think I'll use it again I save the changes and apply them without saving them asa a preset.
FOr example my BIrds preset, has fairly heavy setting on definition and contrast to bring up feather detail, as well as sharpening, saturation, and edge sharpening. So not only are those setting automatically applied. The slider bars are in my adjustment menu for fine tuning. I have presets for fall colours, for boosting shadows, etc.
SO really, I apply a preset, then do a couple of fine tuning adjustments, use the spot tools for problem areas. Usually it doesn't take me more than two or 3 minutes per image at the most. Many times I go out and shoot 200-399 images and spend less than 2 hours processing. For a "roll of film" 36 shots, less than 20 minutes.
You simply cannot get the most out of your images without spot controls, and that was also true in film. You have to dodge, burn, etc, and nothing messes that up worse than trying to do that on a jpeg. Nothing feels worse than when I have an image good enough to sell shot on a point and shoot and realizing that if everything isn't just perfect, I'm probably not going to get it to the "next level".
Jpegs are like polaroids. They give you an impression, and every now and then you see a really good one. Most of the time, you just see hints of the picture you could have had. But hey, I seen people with their fridges covered with polaroids. For some, an extra 5 minutes to work on a great image into a magnificent image is too much. And really , if you have a young family , lots of kids to keep up with no time to breath forget about process pictures, just like polaroids, jpegs are a great thing.
