I've just used a Veho scanner (a basic one, as I was given it) to upload several 100 ancient (35+ years old) slides to my PC but most of them have a strong blue tinge, which I've read is caused by the emulsion on the slide degrading over time. Will Paint.net allow me to pick a single colour I know (e.g. a blue which I know should be white) and automatically change the colour temperature of the rest of the picture to match? I just don't have time to change every colour on every slide independently but they are the almost the only pictures I have of my parents, my in-laws and my children as babies!
