help scanning with vuescan

[taemo]

Finally decided to shoot more film, thus I have to learn how to use vuescan properly with my v600 now

Just tried scanning some films and for some reason, jumping from one frame to another, the exposure of the 2 images are different.

can't figure out how to set them up properly.
exposure I want to get is the same as pic #3


but when I click on pic #2, it changes


here's one with lock film based color mode unchecked

I am sure others will chime in, but I can suggest a few good links to tutorials for vuescan I have collected (the latter 2 for b&w) that you may find useful:

Vuescan adjusts it's level depending on the frame you select, you really need to make adjustments in the color panel before you save.

It also reorients (portrait vs landscape), I have never grasped the underlying logic of what it's doing.

thanks for the links!
I was following Ben's guide on the first link but the exposure and colors from frame to frame is still not consistent.
What I'm doing for now is I'm not auto-cropping anymore and manually selecting the frame to scan, then change CB to Manual or Neutral and tweak the colors from there.

Will give all those links a read today.

Thanks!

I use VueScan occasionally. I find that if I start messing with the options, it's very easy to get awful color/exposure (as your examples above). The only solution is to go back to absolute default options for everything, which delivers a reasonable job.

I've also learned that if the crop outline goes outside the image area, you get crazy results. Keep the crop rectangle within the exposed film area.

Hope this helps.

There are as many opinions about the right way to scan as there are people scanning.
It is useful to read the Vuescan online manual regarding Lock exposure, Lock film base color. For batch scanning I always use those, and then make sure that whatever Filter and Color tab settings you use, click All frames at the bottom, then the settings will not vary from frame to frame. If you set Crop to Maximum, you can use All frames on that too, and do the fine cropping after the fact.
