Beautiful places are of course something many of us want to photograph, but the problem is often that there are constantly people in the shot at such locations. This helpful tutorial will show you how to remove people from complicated images automatically using Photoshop.
Coming to you from Jesús Ramirez of the Photoshop Training Channel, this helpful video will introduce you to median stacking in Photoshop. The first thing to note is that this technique relies on multiple images of the same subject/location, so be sure to bring along a tripod and try to get a lot of images taken at well-spaced time intervals (this way, if a person is standing in the same spot, they're more likely to move out of the way eventually). The median stack mode does exactly what it sounds like: it looks at each value of the RGB triplet for each pixel across all the frames, then assigns the value that represents the median (middle number) of all the values at that spot. In other words, anomalous values (such as a dark shadow from a person standing in the way in a single frame) tend to get filtered out, and the more permanent aspects of an image (such as the sidewalk or a monument) get brought through. It's a very powerful technique, and with just a little work, it can make an otherwise very complicated cloning/masking job easy as pie. Give it a try!
