Originally posted by Na Horuk lol that wouldn't be good, because doing any kind of edits on a jpeg affects its quality negatively (or at least increases file size a lot). The idea is to shoot raw (which has no digital sharpness added) and then post process to add just the right kind and amount of digital sharpness.
I disagree here. I'm a jpg shooter, and always set up my Pentax DSLRs so in-camera sharpening is at the lowest value. I then use Topaz InFocus to sharpen in post. The difference is that in-camera sharpening is accomplished by local contrast enhancement while with Topaz InFocus, you can choose between deconvolution, local contrast enhancement, and the addition of microcontrast, or any combination to achieve the effect you want. Personally, I use deconvolution and micro contrast, and rarely use local contrast enhancement because the latter usually accentuates either halos (on darker subjects with lighter backgrounds) or dark outlines (on lighter subjects with light or medium backgrounds) which are not accurate renderings of the subject matter in the image. This is true both with regular sharpening and fine sharpening for in-camera processing.
It took me a while to realize that the scale used for in-camera sharpening is not really intuitive. The negative half of the slider still represents the addition of local contrast enhancement, and the 0 point is actually the midpoint in amount of sharpening being added, so (-4) is actually at least close to zero sharpening added when the jpg is processed. This gives me a good starting point image with lowest noise for any given ISO, but still retaining detail that can be brought out in PP. It should be mentioned that I almost always use Topaz DeNoise before applying any sharpening in PP to eliminate accentuating noise artifacts with the sharpening, which is a major advantage of sharpening in post only.
