If you want to Photoshop glasses onto someone, there are a few things you need to know. First, make sure the person has normal-looking glasses. If they don’t, you’ll have to find a pair that look similar and use those. Second, make sure the photo you’re using is in good condition. If it’s not, the glasses will be visible and not look as good as if they were Photoshopped on. Finally, use a light background if possible so that the glasses stand out more. ..
