When putting together some images for a group online that I am involved with, a dug out a couple of shots of jets departing O’Hare I shot years back. When coming off 22L, some of the jets make an early turn to the south and you can get a view of them that is either quite level with the wing line or slightly above. When shooting them, they are climbing so it is obvious what you were shooting. However, as I looked at these shots, it occurred to me that they looked a lot like an air to air position except the angles were wrong because of the climb. Since I had shot quite tightly, re-cropping the shot required some Photoshop work.
Taking the image out of Lightroom and in to Photoshop, I selected the crop tool and rotated the image to be the sort of angle that an air to air shot might be. Doing this crops off the nose and tail of the jet. However, one feature of the crop tool in Photoshop is that, if you then drag the edges of the tool back out, you can expand the canvas size. You now have the whole plane in shot but have added some white space in each corner where no image previously existed.
It is a simple task to then use Content Aware Fill to add sky back in to these areas. The result is a shot that looks almost as if you had been flying in formation at altitude. Would you have spotted it? Having done it with an A320, I then had a go with a 757. The light angle makes it look a bit like we are flying along towards a setting sun. I was rather pleased with the trick.
