RAW Sharpness VS Jpeg Sharpness

Sat Jan 26, 2008 10:38 am

When I open my shots in my RAW converter, the standard one that comes with Canon SLRs, Digital Photo Professional I think its called, my shots look really sharp. However when I convert them and open them as Jpegs they seem less sharp, not really soft just not as sharp as they looked in RAW. Does anyone know why this is and what I can do to maintain that level of sharpness when I convert them?

Cheers in advance, Dave

I think this may well be JPEG compression.

Can you save them as a non-lossy format like targa? You can then open the TGA in Photoshop.

I have always thought that RAWs look softer due to in-camera settings. When you shoot jpeg they are sharpened a little bit in the camera. RAW is the actual image like a negative, for some reason the RAW is softer. (this is what I experienced so maybe its just me)
~its a JEEP thang~

Close, but it's the other way around. It depends on the default settings for your RAW editing software. Every time you open a RAW file it has to be processed - the software can either read the settings your camera embedded in the file (which is what the proprietary software such as Capture NX does) or can apply its own default settings (like ACR does).

Like Cpd said, it's probably JPG compression. If your software allows it, set compression to the highest quality setting or lowest compression setting.

That can be turned off and it should be off to avoid jaggies in your images. It's best to apply all sharpening in post processing.
