Still tinkering with my set-up so I decided to add a top light.
I used my beloved Anglepoise which had a daylight bulb. Correcting the colours was an absolute nightmare, daylight fighting against tungsten.
So I tried with another light, this one also had tungsten light. This was a much better option as the correction factors were the same in Photoshop as before.
My next step is to try manual focus, the autofocus is concentrating on the closest part and with a narrow depth of field it leaves the rear part of the model blurry.
