I am photographing some platinum bars for a precious metals company and need a 5600K bulb for my Visico Excel VC300. A constant light source is a necessity for the kind of shoot where you rely on getting the correct light reflection.

You need to learn about colour temperature and white balance.

No present fluorescent lamp can deliver a complete spectrum the way that a tungsten lamp can.

You have two choices: use a blue filter (Wratten 80B equivalent from memory) with your existing settings or set your camera's white balance correctly.

Setting white balance depends on your camera. Most decent ones will have the option to do it manually by placing a white reflector in the shot and determining the W/B from that. You may also have a choice of pre-sets. The light you are using is probably 3400K.

I spent 10 years as a scientific photographer in a metallurgical laboratory.
