When Google sent me my monthly website search performance report, I cried. Despite the fact that mindfulretouch.com is about the only place on the internet where you can learn product image editing for online stores, my top-performing queries, unfortunately, were not "learn product image editing" or "how to retouch for online stores". The top growing query was the same as the title of this post: "how to remove clothes in Photoshop". That's what people are interested in nowadays. They don't want to be like many other product retouchers that earn money while sitting on a couch and watching videos with one eye while editing with the other. They want to use Photoshop to see tits and butts under clothes. What do they think it is, an x-ray app?
Alright, then. If it's you who's just typed "how to remove clothes in Photoshop" into the search tab and somehow ended up on this page, it's my responsibility to enlighten you. If you did what you did you probably have little idea how Photoshop actually works. So keep on reading and I'll tell you all the secrets of the trade in the next few abstracts.
Photoshop can't remove anything. Whatever you don't like in the image, you can either erase it (leaving an empty space or solid color) or replace it. Normally people don't just erase things as it looks fishy, so when we're talking about photoshopping something, it's usually the replacement process. One more thing: you can also draw something using Photoshop if you're an artist, but if you're not, just forget about it.
There are easy to use tools that allow you to replace unwanted stuff with smartly adjusted texture taken from somewhere else (in the same image or even another image). This is how bloggers remove zits on their faces, trash from beach pictures to make the sand look pristine, etc. Zits and cigarette butts alike get replaced with clear skin or clean sand texture from a nearby spot. The color and contract get adjusted so that the affected area doesn't stand out.
So let's use this knowledge and see how you can remove underwear in Photoshop. Erase it? Unlikely. Replace it? If so, then we need some other source of whatever is supposed to be under the removed clothes. Problem is, the source doesn't exist. It means that with just a single photo you can't remove someone's clothes. Period.
But if you've got another image of someone naked, you can probably transplant the naked parts to the clothed individual. But it's not removing, it's swapping, like "face-swapping" – which is a popular technique, google that. I'm sure tit and butt swapping works exactly the same.
Or maybe, instead of tinkering with other people's butts, you could learn something useful instead? You've ended up on this website anyway. Here you can find the biggest and the most detailed course dedicated to product image editing for online stores. Why not learn something useful?
