The problem won't be the camera, it'll be the lights. If you really want to post nice images on the net that convince people to buy your clothing then you'll want good lighting. If you plan on doing outdoor modeling then a DSLR would be a good choice, but indoors, more of the background and lighting will be more important. You could go with an older point and shoot, that has a hot shoe, and do very nice work with the right background and lighting.
To give an example, here is a site showing different lighting schemes. It'll give you a start to doing lighting for fashion/modeling.
I'm thinking about starting an ecommerce site that sells clothing. I want to have the clothes modeled (photos similar to cherrykoko.co.kr or dahong.co.kr), but I don't know what camera would be best. I'm trying to minimize start-up costs, so I'm looking for a cheap camera, but with good image quality. I was looking at the canon 350d, but I want to get some recommendations and advice before I invest in something. I know the 350d isn't manufactured anymore, but if I bought a used one, I could still change the lenses on it. I don't mind if it's not brand new as long as it would serve it's purpose. Is it a bad idea to get a used camera?
any suggestions would be really appreciated. thanks.
