What sharpening do you do to your low ISO RAW images? I started out doing just "Edge Sharpening" with intensity set to 0.9-1 and edges set to about 0.3. This provided good results until I compared this with an image I ran through Canon's DPP software - which appeared sharper with less artifacts. In trying to match DPP's result, I found that the regular "Sharpen" tool in Aperture provided a better result. Using it set to intensity 1 and radius to around 1.5-1.75, seemed to provide nice sharpness without any artifacts. Looking closely, Edge Sharpen appears to increase edge contrast and in doing so, can easily create halo edges which can actually sacrifice fine detail in textures. What are you guys using and what have you found?
