My favorite aspect about retouching is being able to extend past the fashion and beauty industry, and into other realms. This time, I had the opportunity to work with a photographer, Steven Bradbury who specifially shoots and captures our sky above. You can see his work and website at http://www.heavens-reach.com.
When shooting from our home planet and into the night sky, often there is a lot of atmospheric interference that needs to be cleared. Images hardly ever turn out perfect as is. You can see from the before shot below, that there is a lot to be dealt with. There are three big issues that need to be taken care of.
1) With long exposures into the night sky, you will get plenty ot noise coming into the image, especially color noise that needs to be alienated and removed, but not to be confused with any starlight. Differentiating those two things and removing just the color noise is the first step.
2) Light pollution. No matter where you are, it will seep into images and needs to be neutralized.
3) Star movement. With any considerable exposure length, there will be apparent movement that needs to be re-aligned.
4) Haze. With out polluted environment, cutting out the haze and making it look like it was shot above our atmosphere is the final step in getting the best image possible for stars.
In effect, you get a crystal clear image, with plenty of detail and natural colors coming through. You can see the film come right off from all the issues we listed.
