One of the best and most common uses of Photoshop is the ability to remove people and objects from photos in a convincing fashion. This great video will show you how to use a combination of tools to make it look like they were never there.
Coming to you from Jesus Ramirez of the Photoshop Training Channel, this helpful video will show you how to use Photoshop to remove even relatively large objects from an image. When you're using the clone stamp in wide spaces without well-defined edges, I recommend turning the hardness down quite a bit. This will help you feather in the effect and makes it easy to quickly and convincingly blend. Also, it's easy to get a bit obsessive with making the edits convincing; I recommend stepping away for a few minutes after you've done the initial work and coming back to look at the image again. Areas that you thought were glaringly fake might appear perfectly normal when you sit down again. As a general rule, if I can't see those areas within 10 seconds of scanning the image again, I don't worry about any viewer seeing them. Check out the video above for the full rundown.
