I just had a conversation with a friend who's a D100 user. He told me that he shoots with his cam set to record at Large-Coarse. He says he uses this setting because, apparently (according to him), he gets more sharpening control during post-process with Photoshop. Does anybody else shoot this way for the same reasons, but with the EOS 10-D?

Here is a good thread over at Photo.net along the same lines as your question. Post process sharpening is generally more favorable over "in camera". You have more control this way. Sharpen Topic Thread

Thanks for the link to the thread scab-lab. I just read it, and I agree that post-cam processing does the sharpening better than in-cam. It doesn't touch the original question I asked though. I'm curious to find out if setting the cam to save pics at large-COARSE rather than large-FINE (or superfine) actually gives more sharpening latitude? In other words, have images shot under FINE setting actually undergone more in-cam sharpening than images shot with the camera set at COARSE? I hope I'm making sense. Pardon my persistence.

No, the COARSE, FINE and SUPERFINE settings relate to the compression level used when creating the JPEG images.
Coarse images will have more artefacting and be lower quality than superfine level images, with the advantage that they will be smaller in size. It is a pretty straight trade-off file size vs image quality. For the same number of pixels (large in both cases) you can change the encoding quality (coarse vs superfine) and get a smaller in file size, same image size but lower quality image. Both images will have had equal amounts of sharpening done, prior to saving as a JPEG (the sharpening is set in the sharpening options - nothing to do with the image quality option)
In either case, your image has already been sharpened, and has limited latitude for further post-processing sharpening.
If you must use JPEG images but want to post process them, it would be best to set the camera to the lowest sharpening settings (off if possible - one of the reasons to use RAW mode capture) and then do adjustments on the computer and sharpen as the last step.
If you don't want to do additional post processing, the sharpness setting in the camera should be set at a level that suits your style, and the camera settings should be set to suit your needs (e.g., if you want to put the pictures only on the web and have no interest in prints at all, set it to small-superfine) If you are concerned about disk / memory card space, you can use the coarse settings, but you are throwing away quality in the compression algorithm.

I hate the super-fine setting on my camera. It makes edges look gross... sorry I don't have a more scientific wording ;)
I generally stick to the fine mode. |

I turned in camera sharpening off (except for my "past" submission) the other day and feel like I get more control in PS.
My biggest problem is figuring out how to get PS to do what I want it to do, not what I tell it to do.

I take 3 MP image,cropped ,unsharp mask twice and turned into 20 X 30 printable image with very little noise,using Paint shop Pro 7.
E-mail me if interested!

Thanks for the replies. I got my "duh" moment last night while reading the manual on the fine/normal description. That + Gordon's description clarify the matter very nicely.
