PCFoto is a simple to use software for converting scanned color negatives to positive photo images. It is not possible to convert a color film "negative image" to a "positive photo image" by just inverting the colors.
There is a warm brown color cast over the entire surface of the image, which has to be removed and then brightness, contrast and color saturation has to be adjusted.
This requires a lot of trial. PCFoto is specially developed for converting your valuable negatives to positive photo images right on the desktop.
