I'm new to Vuescan, just trying it out. I have a number of questions. (and yes I went through the manual but couldn't get this stuff).
1. When I scan an image it doesn't match the crop I selected. I got threw and make a "preview". Than I put "frame number" to "1" and go to the "crop tab". There I set "crop size" to manual and make that 24x36. Than I change the "offsets" to match up with the frame. I do this for all the frames. However when I click "scan" than the first frame isn't in a 3:2 ratio. So its not using the crops I selected.
2. Next I found the "lock exposure" trick on flickr. Does everyone use this? If so how does it work? I just go to an additional frame number (if I have 5 frames that actually have pictures I select them through the crop method described above than go to frame 6), and than select an area between frames and hit "lock exposure" and I'm set? Or is there more too it than that?
3. Finally using the lock exposure method described above is there any disadvantage to it? Some frames are pretty dark and I would probably be lifting shadows in LR3. Is it better to have them scanned so that the shadows are lifted? Will this reduce noise or anything? Will the lock exposure method + lift in LR create more noise or anything? If so is there a better way to set the exposure for each frame and avoid too many blown highlights?
If you got here thanks for reading through this giant post.
