Hair/cold shoot 3 and 4

Shoot 3, was actually just sort of accidental, my hand ended up covering my top mounted flash gun as it went off and created such an ususual result! the colour change is the most apparent, but i do also like the effect it has on the hair texture and contrasts in the images.

 Shoot 4 was more to try and remove some of the reflections in the hair caused by the use of the mounted flash by adding a thicker diffuser to the flash. however it really doesnt have that much of an overall effect except maybe picking out more of a colour then just black and white.

I think overall the ones that work best are the flash mounted ones. and maybe i should experiment abit with the idea of grids and how they would look overall?
