Hi all, on all most all of my photos from my Fuji GSW690ii I have this… almost glare/bleed. Is this from extra light from my scanning light or from my camera?
Thanks for the help.
If it was from the film camera then you should probably be able to see it on the negatives themselves, easier if you have a viewing light box. However you could try ‘scanning’ parts of two neighbouring negatives with the frame divider in the centre so you get the right hand side of one negative and the left hand side of its neighbour. If you still get that effect in the bottom corners of your scan then it couldn’t have happened in the film camera. Conversely if it is in the corners of each frame then it must be the film camera. You can also scan a blank unexposed frame but with an exposure/shutter speed to get the histogram roughly centred.
What happens if you scan the flipped image?
That’s not definitive though, not what I was trying to get at, I meant to scan across two frames.
Great tips, thanks guys.
So the vignette still happens when taking a photo across two frames. So that means it’s not the film camera, thank god.
It still happens when the negs are flipped, so again seems like it’s the lens vignette.
What’s odd is that it doesn’t always happen, which made me think it was a light leak.
Good that your film hasn’t been wasted. So now it’s a question of looking into your camera copying setup. I’m assuming that these are transparencies? It’s a bit strange because copying 6x9 isn’t as demanding on a lens as scanning 35mm, much lower magnification.
Yea totally. Would you agree this is vignette from the lens?
When I scan 35mm with this lens (Nikon AF Micro NIKKOR 55mm f/2.8) it doesn’t have the vignette.
I guess the ultimate way to test it would be to get the negs lab scanned.
Sorry, I guess these are colour negatives not transparencies….
I think we’ve established that there is nothing wrong with the negatives themselves so I don’t think getting a lab scan done will help you discover what is going on. I really wouldn’t expect that lens to vignette like that though. Could you maybe say more about your setup?
I scan with:
- D800
- CS-LITE Camera Scanning Light Source
- CS-LiteBrite+ 2.3x Light Enhancement & Color Negative Calibration Sheets
- Nikon AF Micro NIKKOR 55mm f/2.8
- 120 or 35 Valoi holders, taped to prevent light leak
Thanks, and a copy stand perhaps, or maybe a tripod. I’d go back to my suggestion of scanning a blank frame of colour negative and choosing a shutter speed to centre the histogram, basically to give a mid tone. If you don’t have one could try without any film at all but having some film in the holder is more helpful in my opinion. Then, assuming your examples here are also colour negatives you invert in Lightroom and boost the contrast to examine the evenness of illumination. Then maybe repeat without the enhancement sheets but adjust the shutter speed accordingly.
Flipping the image also flips the issue → The film must be the reason.
There might be a contribution from the setup. Take scans with default exposure (no exposure compensation) and focus setting as well as aperture values of 4, 5.6, 8, 11. - without film.
- Set crop to just remove the film holder parts
- Check the image (can you see some falloff?)
- Check histogram width (should be narrow)
- Move corners of the RGB tone curve inwards, but keep the central hump centered
- Check the image (it should be equally grey)
Not here, copying across two frames shows there is no problem in the corners of the actual film frame. I think that the problem is in all four corners of the digital capture though.
Look at image (number 3 in this thread) and its flipped version (number 6) and foreground corners with their red glow. I see now such thing in the corners with the sky though. This hints at an issue with this image. The images differ in size and crop and the glow is slightly different, that’s why I’d check the setup, which might add to the overall issue.
The strip separating two images has no apparent gradient, but there is some glow in the corners nevertheless. There seems to be an issue with the setup too.
…given the information we have, I can’t point my finger in an either-or manner. To me, it looks like a composite of different issues.
We’d need at least one OOC raw file to dig deeper. Share your image(s) here or use wetransfer.com.
I can see no effect in the two foreground corners visible around the frame separator when the digital capture straddles two frames, other than a very slight spread from the corners of the digital capture which (to me) shows that it is not on the film. To me the reason why the effect doesn’t show in the sky when the film is flipped is that the impact varies in proportion to the density of the image on film, so in the sky (denser on the negative) you don’t see it whereas in the (underexposed) foreground the proportional difference is much greater.
Things aren’t easy to see indeed. So I took one of the posted images and edited them to make differences more visible.
Possible causes of increased brightness in corners or sides
- atmospheric conditions, lighting of the original capture on film)
- original capture setup
- scanning setup
Again, we’re all guessing, and for a definitive answer, we’d need a piece of film (not possible) or at least a few OOC raw files, also of the scanning backlight without film and without film holder.
Evaluating the scanning setup
-
Scan of the backlight as seen against a grey background. The histogram is fairly narrow.
We can still see hints of darkened sides and edges and some dust on the lens. Under normal conditions, this setup is good for all but the most demanding negatives. -
Enhanced representation, note the wider histogram and the aggressive tone curve
Now, things look terrible. We can see lens falloff, dust … and the diamond shaped structure of the light spreader of the Kaiser Plano. We can also make out the text printed in white on the front of the 7Artisan 60mm macro lens. Under normal conditions, only the dust will matter.
Happy to provide this. What is OOC?
