I think it will be a good idea to narrow down the varied themes. If not, we will be going nowhere. I am more interested in commerical studio kind of pictures. If pictures don't sell, there is no point in spending the time and effort. Though other pictures sell too, but are we still sticking to studio work? Perhaps, we should make it clear from the start that certain themes are out. For example, how are we supposed to do landscape photography in the studio? Who would be so free to construct the mountains, hills and rivers in the studio? Anyway, that is still not landscape photography also. In terms of product photography, I don't encouage abstract also. The boss is going to go after your neck if you make the customers guessing what product you are shooting. Better make the product clear and sharp. Can be a bit moody but never abstract.
