How the guitar shot works.... Roughly.
Ok, this is tricky. Not because it's a particularly hard shot, but because I tend to have images in my head which I translate into pictures. This skips the logical planning part and makes my lighting hard to explain. I'll try though.
The guitar is placed on a black cloth sweep. It needs to be cloth because that absorbs the light better than paper, and it provides more grip on the point where the £3000 guitar touches it.
Now, according to my contract, I must tell you that the guitar is a VANQUISH MYSTIQUE made in Peterborough UK by Adrian Hardman. Ok, obligation covered!
The guitar is angled so that no part is covered by the cloth where it touches, and the bulk of the instrument is as far as possible from the background.
Next, the key light source has to glance off the highly reflective parts at such an angle as to be lost. This way the specularity is reduced.
Further to this, the light is diffused by a 60 inch heavy duty black-backed brolly. It's black-backed because ambient levels are low and no additional light in the surrounding studio area is wanted. A softbox would be equally good or better, btw.
The key light is a 600ws interfit strobe. I love interfit strobes! Simple and dependable.
Then, another light is placed roughly at 90 degrees to the first, and set about 2 or 3 stops lower. This is angled to fill in and provide a more 3d look.
After this, small white reflector cards bring up the headstock.
Ummmm.......... That's about it really.
Sorry.
