ContrastMaster increases the color cast and vignetting in some of my images. Why?
Low contrast photos usually do not exhibit noise, artifacts, color casts or lens vignetting. But when adjusting the contrast these imperfections become quite visible. As ContrastMaster can improve the contrast quite dramatically, there is also a good chance that it will make these things more visible. If you do not want to live with lower contrast images, you should remove noise, artifacts, color casts and lens vignetting before running ContrastMaster. You can also do it after running ContrastMaster, but doing it before lets you easier judge the effect in ContrastMaster. Another alternative is to improve the quality of your photos, e.g. by using a DSLR camera, avoiding a high ISO setting and shooting RAW (in case JPG artifacts are a problem).
