Dealing with different film types
If you look at a colour negative film, it has an orange colour to it. There are obscure reasons for this. But it's important to realise that the amount of orange will vary between one type of film and another (although it's reasonably consistent if you stick with a single film maker).
Other aspects of a negative's colour will change between films: some will be warmer and others colder.
Straight out of the box, I found that the Coolscan did a reasonably good rendition of colour for Kodak films. But Fuji ones from the 1980s were way too blue/green. (Hint: when you look at a Fuji negative from that era, it looks much more orange than the Kodak one. The negative colour for of orange? Blue/green!)
Here's what to do:
For each film type, find a negative that is well exposed, was taken in natural sunlight and has a neutral grey subject somewhere in the image.
Do a preview of the image
Open the Curves window, and click on the middle eye dropper. This is the one for setting grey points
Click on the grey point in the image. (Note: it doesn't matter if the grey point is light or dark. It just needs to be a neutral (uncoloured) shade of grey.
The curves will change with the three primary colours going up or down, and, if the image looks natural, then this is the curve you will want to use for most photos in the film
Whilst those curves apply, click on Settings and save the settings with a name like 'Anthony Fuji HR 100'
Later, when you select an image to scan, you can apply the 'Anthony Fuji HR 100' setting to any image from that type of film
Sometimes you'll still want to preview an image if it was taken under unusual light
