Color presets for Aperture

[kansas_parker]

I'm having issues getting the color of my film scans correct in Aperture, especially my slides. Does anyone know of any presets out there to adjust the scans depending on film type? I've tried messing around with the levels manually but I just can't seem to get it right. Here's an example of Velvia 100 with a bit of a magenta cast that doesn't appear on the slide.

It looks like you have some white areas on which you could use the eyedropper tool. If the cast is consistent you could stamp the resulting white balance to other frames or make a preset.
