Ok, so this is a new section of my blog which I am not sure if I will have enough content to share with all of you but I am going to do my best.
This is a little trick that I picked up from Joe McNally and It works great. To make a big light source use a white bed sheet and place the light that you are using behind it. Move your light source back a little to make it bigger.
This shot was trying with the halogen light place behind a white bed sheet and also using a flash to camera right and another continuous light on camera left. As well as a little playing around until I got the settings to what I wanted and some twicking in Photoshop.
