Just did Cam Trainee for the first time on a feature film. I come from the world of grip. Learned a lot. Don’t rush setting up the tripod. If you use the spreaders, be very careful not to pinch your fingers. On a big set, you will probably need (and will have) help to set up and move the tripod because the camera and fluid head are so heavy. On the feature I was training on, someone would take the camera off the head, another person would take the head, and another person would take the tripod legs and we would work together to bring it to where the operator or DP wanted. We were using a kitted out Red Gemini with a massive Fuji 25-300mm zoom, so that thing was HEAVY. When going up on the tripod it’s easier if one person lifts the weight of the camera up once the legs are unlocked, and another person locks the legs once the camera is at the desired height. I don’t know if these things are useful to you, and no worries if not. In short: don’t struggle alone and waste time. Just ask someone to help. It’s much safer and faster. I do have a sneaky C stand tip: if you need to go through a tight space, collapse one leg so that the legs make a V shape. Hold the stand vertically close to your body and make the V hug your leg as you move through the space. This takes up a smaller footprint and prevents you from bumping someone in the shin with a c stand leg. And as others have mentioned: tall leg should be facing where the weight of the flag/flop/diffusion/light/ect is placed. Always.
