I guess I had this idea that it wasn't a good photo unless it was good coming out of the camera before making any adjustments in Photoshop. Am I correct in assuming that a large percentage of photos that I see on this site have had some post processing applied?
Mcmm, welcome to the Hog, and yes, your assumption is actually correct.
1st, about sharpness. The sharpness that is seen by a normal eye(neutral sharpness), is represented in a Canon camera as a sharpness of 3. Canons default sharpness setting as a camera is delivered to the consumer is 3(neutral). You can of course change that, and if shooting RAW, can be applied after the fact. If you are set to less than 3, you are actually getting a pic that is less sharp than seen by the eye. And 4 or more is adding sharpness(contrast) that is beyond what is neutral. keep in mind that a pic can not be made sharper than how it was taken. The process is only creating a higher contrast, along contrasting lines, to make the areas appear mor pronounced giving the appearance of sharpness. There is no substituted for good technique, including sharpness. A very fine line will quickly pixelate with even moderate sharpening and be obvious to a trained eye.
If you're set at 3(neutral), and the pic is taken sharp, then NO additional sharpening in post would be necessary.
The reason all RAW pics need some PP, is that in RAW, the file does not represent what the eye actually saw, and we want to get it to that neutrality that our eye had actually seen as a starting point. It is just the nature of the beast we call RAW! And we are of course free to go as far beyond that as we wish, which is where all of the controversy comes in.
The problem is that many try to take a crappy pic, and think that if they PP the beejeebies out of it, that somehow they made it better. But it's still the same crappy pic, masquerading as some kind of art.
There are great shots that can benifit from removing a piece of trash, or increasing a highlight, raising a black hole to pull some detail etc. but you have only improved small details, not overhauled the composition.
Your question was about sharpening, I hope that helped. ;-)
