I am looking for simple adjustments for photos. I remember using some very nice photo corrections in Paint Shop Pro years ago that allowed to adjust all I mentioned in the title with simple sliders. I am missing especially photo temperature and white balance combined with luminosity for highlights, midtones and shadows. I have installed some plugins for Paint.net, but they don't seem to provide the same functionality, for example the "temperature" slider just adds blue or yellow tint to the picture, instead of simulating the wavelengths of a given light source. What's the best solution in Paint.net for these adjustments?
