The models really do look nothing like this at all. The skins have been yellowed and the red and yellow clothing are far too garish. Terrible and quite annoying as I actually got a Best Painted award for this team at a tournament.
I knew I really did need to get some extra lamps so I have been keeping an eye out for something cheap on eBay - and I did eventually pick up a light box with four different backgrounds, two lamps and a camera stand all for the princely sum of £13! I had also seen a webcast where a professional photographer had said that cameras in phones and small digital cameras save the image in .jpg format which means the device is doing a lot of the processing of the image before it's even saved to the memory card. What you do in post-processing is fix what it messes up. He took photos in a .raw format and uses his computer software to adjust the raw image data.
