Does anyone else have a problem of working on a subject but it photos better at diff angle, then of course you ve lost your light source, 3-dem, and its not the same picture, one of these days.
it all has to do with your light source, make it bigger and more diffuse
or take the picture outside in the open air, the best light you can get, you could even use some white papers to lighten the dark areas.
