vuescan advanced workflow, raw, and other ?'s

[jano]

I'm reading the vuescan advanced workflow technique where the guide suggests locking exposure on a blank frame, etc etc.

I tried this once a while back before I was comfortable using vuescan and ended up with some strange results. So I hesitate to approach it again, however, I'm sort of in a learning and curious mood.

Here are my questions:
- does the advanced workflow work with all types of film (slide, print, b&w?), or are there specific ones I should stay away from?
- does the advanced workflow have any affect to stuff on the "color" tab, where the color balance stuff is? (maybe better worded, do the color tab settings have any affect on the advanced workflow)...
- that color tab has often led me to have weird problems, never sure what to set it to.. typically whatever gets me the best results. If I'm scanning "raw" files to edit later, will this have any affect now, or only later when I reedit the files?

With regards to the "raw" scanning, it seems this is a fairly quick way to get to basic adjustments on the files. I'm not sure if there's a question in here... ... just trying to figure out how to minimize time in PS, as my computer is fairly slow with the big files when I want to work with them, and it's time consuing and frustrating beause PS is so slow! Maybe I should buy a new computer instead of a new lens.... !

So how do ya'll do this? Better to keep it simple, scan as positive, work in PS? *shrug*

It's worked well for color for me sometimes. Has not proven helpful with slides or B&W. That's just me. I don't scan color neg that often so I haven't mastered this technique either.

...some questions to which I do not know the answer...

RAW gives you a raw vuescan data file. You can use vuescan later on, change all the settings - color adjustments, film profile, curves, etc - and it'll produce a whole new file as if you scanned it again. However, these files are used in Vuescan only - they are not like the RAW files you get from a digital camera. You must open them in Vuescan, make your changes there, then output a new file.

With vuescan, there is no need to scan as positive then invert. Just scan as a color negative, 48 bit TIFF if you can. If you got the HD space, also save it out as RAW, and work with the TIFF in PS. Go back to the RAW if you need to and output another TIFF.

This will end up in the wiki at some point, trust me!

Okay, thanks again, Allan, always there to help

I remember having all sorts of weird trouble in the advanced workflow before, I'll have to try it out. Also found this nice tidbit, that's applicable to me (for once, woohoo!). Trying to get the grasp of it, but it seems the workflow is primarily for c41. Slides and b&w is something else, but I can still use RAW for that.

Okay! Slowly making sense!

i think raw is the only good thing about vuescan. the color tab is basically useless. it sucks!
