I'm a novice at EOS60d Studio. I bought it for 60D, and I have a small studio, Three Lamps District. How to set the camera to take good photos?

The first is to set the format, preferably the maximum format resolution of RAW or JPG. Of course, whether it can be made into a RAW format is another matter. The most important thing is to set the color temperature. It is best not to use automatic color temperature, but to use manual color temperature. I don't know whether your three lights emit white light or yellow light. Generally, 5000-5600K is enough for the flash lamp in the shed, and about 5500k for the tricolor energy-saving lamp. If it is a tungsten lamp, it is set to 3200K. There is no need to set anything else.
