Photography-How to shoot a flat suit?

I don't think either method you mentioned is desirable. They complicate things and artificially add trouble, which has no good effect! Your existing equipment can fully meet your shooting needs. Because the power of your two lamps is the same, if you want to take a stereoscopic effect, you must keep one of the lamps away from the subject, which will give a stereoscopic effect of alternating light and dark (appropriate soft shadows will help to express the texture of the object). As for taking light-colored clothes, they are not bright because of insufficient exposure. Because the metering camera will think it is too bright for a white object, reducing the exposure will turn white into medium gray. Therefore, when shooting light-colored clothes, it is necessary to make exposure compensation (increase the exposure of the second gear to the third gear), and this effect will come out.
