Many books, guides, and videos have been published on product photography, there are many “experts” on the subject, and one can go crazy trying to sort through all the information. The following general guidelines are personal opinions based on some experiments I conducted in 2015 while helping a friend shoot some product photography for his wife’s business. I am most certainly not an expert in the subject matter.
Although I’ve shot with constant lighting (tungsten, fluorescent, and LED) and both studio strobes and speed-lights the easiest results (again, my personal opinion) can be achieved with placing the product in a light tent fitted with an white infinity sweep, using whatever lighting you have available, set your white balance for the type of lighting (preferably measured with the camera), set your exposure with a[ flash] meter or meter the light reflected from an 18% gray card, use a polarizer if there [are] any reflective surfaces on the product, and use the smallest f-stop on your lens (maximun depth-of-field at shooting distance).
The following photo was made while I was testing different lighting and shooting setups.
It was exported from a RAW image shot on a Nikon D300 with a 50mm (effective 75mm) lens, which was fitted with a circular-polarizer, set at f/8 and shot at 1/60th of second (both manual settings), using two 300 watt-second studio strobes (metered at f/11 for the left and f/14 for the right). All reading were made with an [Sekonic flash] meter, and no adjustments have been made to the image. (I would be more than happy to discuss the full physical setup in a private message.)
