Polishing plate for photography: round or square?

Hello: The shape (area) of the reflector determines the extension range of the reflective light source. With 1 10cm(44 inches) as the dividing line, there is really little difference between the round model with a diameter of 1 10cm and the square model with a long side of 1 10cm. However, if you need to complete the car body, the reflector larger than 1 10cm will be presented in the square style you said. After all, it is not practical to make such a large size into a circle. In addition, fill lights with such a large size will be used, and most of them are full-length portraits, so they will be presented in a long (square style). So you will find that most of the reflector sizes on the market are set according to this. = = = = = = = = = = = = = = = = = = = = = = When purchasing a reflector, you should consider your own needs and choose just or slightly larger than the target (the range that needs to be supplemented). For example, the range you want to fill is relatively small, such as the upper body of a portrait, or a medium-sized commodity. Consider a 80cm round reflector! ! If you fill the full-length portrait with light, you can consider 1 10cm round or larger oval (square style) reflector. Another concept, although large size can cover the fill light of small size goods. But big is not necessarily good, it depends. For example, you want to shoot a cup, but at this time you only have a 1 10cm circular reflector in your hand. At this time, if you want to fill the light, you might as well take a piece of white cardboard slightly larger than the cup to fill the light, so that the light filling area will not be too large, and the light control will lose its function. Secondly, because the reflector is too big, it is not easy to use both hands and feet. The above is provided for your reference. reference data
