For the photoshop work shop we were taught how to import loads of photos at once by placing them as smart objects, - file - scripts - load files into stacks. This means you dont have over 100 windows open if you were to do in manually and also means editing between photos is easier. We used a technique that took the median of all the photos we put into a stack and essentially took all the people out of the photo by comparing each photo with one another.
When you take the median image from the stack it takes away all the people, but the clouds get blurred together, so by placing a single original image you can select the sky you want by just deleting the bottom half of the photo to delete all the people. Need to rasterize the layer from a smart object to edit it.
I decided to take my photo a step further by maybe including one of the people in the photos.
I thought why stop at that though when you could place the grumpy cats head on his.
