What's perfect to you may not be perfect to someone else, That is why this pro grade camera offers so much in the way of adjustments. One doesn't often GET the perfect picture. More often, one must CREATE the perfect picture..

Set the flash at "0" for the most uniform pictures, and try a better lit environment and work in the 4' to 8' range. Generally, your pictures taken outside in good light, with the sun at your back will be the best. The rest, especially flash, often require some manipulation of the environment..I.E. lighting.

A perfect picture requires a perfect subject, perfect pose, perfect foreground lighting, and perfect background lighting.

So, the answer to you question is; there is no perfect setting, which will constantly produce perfect pictures.

Good Luck..
