Alysonhallphoto Posted Monday at 06:43 PM Share #1 Posted Monday at 06:43 PM Advertisement (gone after registration) Wondering if anyone else has ever experienced extreme vignetting on select frames? It’s on the negative so not a scanning issue. I use a summilux 35mm 1.4. At first I thought it was a battery issue but it still happens even with a fresh battery. Welcome, dear visitor!

TeleElmar135mm Posted Monday at 07:10 PM Share #4 Posted Monday at 07:10 PM Make some test-shots without the hood. If you used a fiter, revove them also. But to me it lools like the hood, sitting not correct on the lens. And check that you got the right hood for your Summilux - there a different SL 35mm lenses with diffrent hoods.

andybarton Posted Monday at 07:14 PM Share #5 Posted Monday at 07:14 PM It looks like the right hood, but to only affect “random” frames is odd. If it’s not seated correctly, that might do it, I suppose. I’m assuming that the hood came with the lens. Link to post Share on other sites More sharing options...

Looks more like shutter issue to me, but irregular shape is quite odd. Looks as if the shutter traveled slower in the mid of the frame than along borders. Run few tests with ground glass/can be a piece of blank negative, check different distances. You can try to record shutter movement in high speed mode on your phone. But if it’s not hood or filter related I’d seek professional help. additionaly this banding on the sky doesn’t look right, can you post a photo of negative with perforations and inter frame space?

Appreciate your insight!That’s what I was thinking too… Hard to see much detail in these but hopefully that helps. It happens so seldomly that I’ve overlooked it but when it does happens it’s so hard to ignore. Welcome, dear visitor!

Carlos cruz Posted Monday at 07:59 PM Share #8 Posted Monday at 07:59 PM Very odd, negs look clean, nice density, no hint of vignetting,l. Is frame 20 on the first photo the same picture with you posted in your first post the one with birds and tilted horizon? I suspect something could have happened during scanning. For me negs look absolutely ok Link to post Share on other sites More sharing options...
Sandokan Posted Monday at 08:11 PM Share #9 Posted Monday at 08:11 PM Looking at negs of 20 and 21, hard to see here but is there a symmetry to the "vignetting" across the separation line? I am thinking maybe a light leak? When I had a light leak, it was on some frames but not others and all depended on how I held the camera and squeezed Link to post Share on other sites More sharing options...

There are dark streaks across the negative as in the seascape and gulls in photo 3, so maybe shutter, but the desire for people to always want to use a Summilux wide open can introduce other problems such as vignetting. So I think its primarily shutter drag but the streaks also point to a light leak in the shutter blind. Link to post Share on other sites More sharing options...

Maybe slightest vignetting but nothing close to one you can see on positive. I blame the scanner. Link to post Share on other sites More sharing options...

The negatives looks like an A4 scan on the flatbed or a phone photo .... how does vignetting happen there? As Alyson says "it is on the negative" which means they can see it with the eye.

I just re-scanned the image to double check and got the same result (and the rest of the roll is totally normal). You really can’t tell in the images I sent but if you look really closely at the negative in person you can indeed see the lighter areas indicating the vignetting is on the negative. The striations are also on the negative. Not ruling out it being a scanning issue but seems unlikely?

Carlos cruz Posted Monday at 08:52 PM Share #15 Posted Monday at 08:52 PM Actually the colour of the vignette looks odd for typical hood/finger in the frame thing, if it was true we should see a bright yellow blotches on the negs too. I think the bamding we can see on the sea birds photo is very telling, it looks like scanner camera moving along and struggling with something(?) can’t tell if it was some internal reflection or some dust. I am shooting in the dark here. From my experience negs should look different to give you such strong effect. Link to post Share on other sites More sharing options...

Good grief can’t you see them? And given they are not orange in colour they must be coming from the shutter side of the film.

This one definitely shows some vignetting unless it’s the side of the mattress not getting any dialect light. The problem with vignetting theory is that the shape of your vignette changes, similar shape is on in some pics on the left, on the others on the right. Are you sure there’s no chance of stray light pr something with your scanning setup? https://forums.negativelabpro.com/t/solution-found-for-blue-vignetting-on-negative-scans/2452/5 Found this link and I believe it describes similar problem. Probably something in optical path of scanning camera amplified by software lens recognition or lack of it. 12 minutes ago, 250swb said: The dark streaks in the sky in photo #3, if they aren’t incompetent scanning they are a light leak.

TomB_tx Posted Monday at 09:33 PM Share #18 Posted Monday at 09:33 PM (edited) I'd also suspect the shutter - looks like it's nearly capping at the end of the negative. If so it will be worse on high shutter speeds. Do a test roll with a variety of shutter speeds. Edited Monday at 09:33 PM by TomB_tx 2 Link to post Share on other sites More sharing options...

I’d still answer that I haven’t seen black light leaks before. We are seeing here a positive picture, not a slide, not a negative. As those marks are close to middle of the film I’d rather suspect scratches from hanger when drying (usually occurring closer to frame 18, I usually judge film labs based on those) Link to post Share on other sites More sharing options...
