VueScan Help - Poor Exposure and Color Cast

[Pete B]

Looking at my posts above, doing the 4 prescans in Vuescan gives less cast than Fizzlestick's method. However, simple PP in photoshop give's little between the final results.

Using Vuescan is very long winded when you consider theacceptable results from silverfast and epsonscan, especially if batch scan is implemented in Epsonscan.

Roll on Silverfast and the Plustek 120 as far as I'm concerned.

Just as a foot note, I'm not able to avoid blowing highlights with any method other than the method I first posted with 4 prescans.

Color Variance?

Color Variance?

First off, thanks everyone for offering advice on how to get a decent workflow out of VueScan.

I have a great number of color negatives I need to scan and I want to figure out which workflow will suit me best. Ideally, I need to avoid spending time tweaking each and every image. Rather, I'd just like to bring them all in at decent quality and spend time tweaking certain ones.

So I followed all the advice given and I think the method that gave the best quality is to scan negatives as "Slide" in VueScan and then invert that image in Photoshop (RichW's method). Which works great for certain images, but is a little too time consuming for batch scanning rolls of film.

Ideally, I would like to figure out how to get "acceptable" images right from VueScan alone. SilverFast gave better results but I'm unwilling to spend the $$ to get Ai Studio and the cheaper version only kicks out 24-bit files. So ideally I want to figure out what these VueScan advocates are doing and find a way to get acceptable quality.

My current issue with VueScan is I can't figure out the setting I need to tweak to get greater color variance. When I invert the images using SilverFast or PS, I see a great range of the color green in the leaves. There is dark green, medium green, light green. However, when I invert using VueScan I see everything as one shade of green. And that's a problem, because I can't tweak that in PS. No matter how much I play with contrast/vibrance/saturation it doesn't come out as a range of dark/medium/light. All the leaves remain the same shade of green.

Any idea what I can adjust in VueScan to capture a greater range of color? Currently I am scanning Negative, Locking Exposure & Base Color, settting it Generic and setting it to Auto Levels. Adjusting the curve or locking Image Color in VueScan doesn't help.
