Rendered view what settings to remove strong shadows?

imported my obj from Photoscan, all looks very smooth and as per original , but strong dark shadows as if in full sun, they are stopping me appreciating the model and spotting holes etc, as they look like holes.

stage and default lighting choices are same.

what settings do I need to get very mild shadows as if on a cloudy bright day ?

also in shaded mode the realistic looking skin and trousers on my human are like the surface of a boiling pan of water or stormy sea ! how can rendered remove the apparent lumps and bumps of the model ?
