I found this link very interesting. It allows you to make a diagram of your lighting and type of lights used and then will allow you to print it out, how cool is that? I think it's a neat application to remember certain lighting schemes while experimenting or even to show new employees lighting schemes you use. It's called Photo Diagrams and it's free so what the heck right, why not give it a try. It can be used for just about any type of photography from product display, wedding photography, portraits, pet photography, you name it you can record a record of what lighting scheme you used. Who knows it could just be the app that helps to make you the best photographer ever.
