One of my pet projects on VEF is the cover index for the German mag Sexy. Many of the covers there are scans, though the majority are auction finds, and as such typically photographs. One particular vendor has the unfortunate habit of photographing the covers whilst they are still in a plastic bag. The result of this is that it really dulls the colours.
Here are a couple of examples:
In comparison, this is what the last cover really should look like:
What I'd like to hear are some tips to reduce the effect of the dulling. I had a go at one of those images, throwing all sorts of things PaintShop Pro (my pic editor) has on offer at the pic. The result (below) is still not great, and worse - it was quite a bit of effort, as I was not really sure what I was supposed to be doing. Thus I'd like to know which settings I should tackle, so that I can turn this into a script to turn the whole affair into (eventually) a low-effort thing.
