Taobao's clothing shooting, the body is Canon 600D, which lens is suitable?

18-55 is no problem. When the indoor space is small, 50 fixed focus can't be opened. The most important thing is to make good use of light, slightly adjust some simple equipment, even white cloth and white paper, and use them to reflect or refract light to minimize the shadow of the shooting target. As long as the photos are clear enough, other problems can be dealt with later. It is impossible for Taobao to sell things without post-processing, because even the most advanced cameras have color difference problems. Be sure to learn the application of at least one image processing software, just like people who take wedding photos. To be sure, there is absolutely no one who does not go through post-processing.
