Also need one from head on for judging Sergio. The darkness is because your camera is trying to compensate for a white background. Use a more neutral colour like gray if you can.
Thanks boys,I like that you like, that makes it great to work on other models as always becoming more complicated and laborious for the better every day.
Andy if there good lighting and do not touch the camera settings compensated pics and leave, but it was not my camera was the phone and try to compensate a white, were also made in the work was not done at home, in I have the box home to photograph and is very noticeable when taking pics there or not. I have already made the new pics with the camera and with the right lighting.
Well will erase the photos and will place new ones this time from angles that mark, as always just put the pictures I thought it was no problem, but still the problem recurring.
