Photo tip Friday 6
After an afternoon of photographing jets and helicopters in St.Thomas at the “Wings and Wheels” airshow I came home wanting for a longer lens. Without shelling out cash for a new lens or a tele-converter I compensated (and some would say I cheated) in Photoshop.
6, Crop your images.
My Canon 70-200 f/4 lens preformed well at the show, but I would have loved to have a 300mm lens (or longer). When photographing objects like planes, birds or many other subjects you want to fill the image with your subject.

So what do you do when your longest lens is not long enough? In some situations the answer is the crop tool. I do understand this limits the possible print size, but when sharing online you can crop a lot of the image out without loosing quality.

Cropped image with the subject filling the frame.
My Canon XTi shoots 10,062,144 (3,888×2588) effective pixels and for the pictures I put on Flickr only require 240,000 (600×400) pixels. This resolution would look horrible printed but for sharing on my blog or other websites 600×400 is enough, meaning we only need a small fraction of the image, so trimming a bit off the sides wont be too detrimental. Be careful, the more you crop out, the more obvious problems with focus or noise become.
Keep in mind that we can still use this technique for print, but you will loose print quality if you crop out a lot.
