One of the most useful things you can do in Photoshop is remove an object from a photo, whether that's a building ruining your landscape shot or that person that wandered into a shot of the bride and groom. This great video will show you five techniques for removing anything from a photo using Photoshop.
Coming to you from Nathaniel Dodson of tutvid, this helpful video will walk you through different tools and techniques for removing objects from an image using Photoshop. Before I ever got into photography seriously, I always thought of Photoshop as that program where you could remove people from and insert them into photos. It turns out you can still do it, and it's gotten pretty, pretty good at the task. As is always the case with the program, there are numerous ways to accomplish that task, and it really depends on the situation and what you're trying to remove when you're determining the right tool to use. Here's an extra tip: when you're working with the Clone Stamp tool, it often helps to turn the hardness down and work with a very soft brush. This tends to be much more forgiving when you're brushing it in and naturally blends the results, saving you time in a lot of situations. It's particularly helpful with landscapes, I've found.
