The best tip I have been given so far is for anyone with a small studio space like myself. One of the biggest issues I have come across comes in the form of light bouncing off of areas it shouldn't. When you have a small space to shoot in, light tends to bleed out onto the floor, ceiling, and walls. If the object you are taking a picture of is very reflective or calls for very specific lights and shadows you may end up with problems everywhere. Here is where the tip comes in...
Best case scenario, If you can paint the walls and ceiling, paint them matte black. It will stop most reflections from getting in your shot and will give you better control of your lights and shadows.
If you can't paint the walls or don't want to feel like you are working in a dungeon, buy some black foam board in various sizes. Not only can use these to block light from bouncing off of the walls, ceiling, and floor, but you can also use these to block unwanted reflections that show up.
Hope that helps!
