In the 4th picture, the red coloring was added by placing my hand in front of the camera's flash. Similar to how you can point a flashlight under your finger and the other side will glow red, I attempted to use the same concept with my flash.
An old 6mp Nikon. I really need to update to a newer model Nikon. I picked up a Sigma lens, the funny thing is, it's worth more than the camera at this point. I use a lot of different lighting though. I have made my own light boxes, lens diffusers, party bouncers, etc. All of the pictures displayed here are free hand. No tripod or anything. I just started using my tripod.. and it makes a huge difference.
