No special settings, just take your pictures outside on an overcast day. Use the "auto" setting. Lighting is the key, not settings.
Here's an example from this morning. Camera was my Canon EOS-M, but it could have been any camera. Setting was "A" for aperture priority; aperture was f/5.6, ISO 400 with the camera making the decision what shutter speed to use. I took my little Winchester M12 outside, placed it in some open shade, and took the picture.
Lighting is everything, and pictures taken outside in open shade will almost always look better than pictures taken inside using standard home lighting, or pictures taken with a camera's built-in flash.
