Step One: Get Rid Of The Glare From A Slide Scan

No matter how new or old your slide is, your scanner will scan the gloss that comes off a slide.

This leaves you with flat, faded colours. Yes, time also fades colour. But the biggest issue is the scanning process itself -- it's not perfect.

To get rid of this without touching any of the real colours of your image, do the following...

GIMP > Colors > Auto > White Balance

What you're doing here is getting rid of the glare that your scanner picked up during the scan.

In other words, you BALANCED all the colours. And that flat look is now gone.

Now you can start to brighten and heighten the colours. Here's how...

Step Two: Brighten And Heighten Colours Using Saturation

Once you got rid of the glare, you can begin to brighten the colours. Go...

GIMP > Colors > Hue and Saturation

What you did here is, saturation brightens all the colours in one easy step.

To use Saturation, move the slider to the right, just a bit. I went to 19, but you adjust accordingly. Don't saturate too much, though. The colours will look "plastic".

The Final Result: Slide Scan With Faded Colours Fixed Using GIMP

Lets see a before and after...

Before gimp colour fix slide scan

Before GIMP colour fix -- colours look funny (blue looks purple) and the image is flat because of the glare off your slide film.

After gimp colour fix slide scan

After GIMP colour fix -- colours look natural, and you got rid of the glare that made your scan look flat.

Wait! You're Not Done...

To make the colour pop even sharper, brighter, and more defined, you need one more step. You need to fix the exposure. Once you do that, then you'll see a huge difference.
