Vignetting?

[sfb_dot_com]

I'm gonna go with the polarized light effect. This looks very similar, but a lot less noticeable to an effect I'm getting on some slide film I shot in Finland. I was of course using an extreme lens (12mm Heliar) with a simple meter (Bessa L), so some of my problems at least were due to underexposure. Certainly the ones it is most pronounced on seem to be either beach or sunlit scenes.

Another possiblity is a misaligned lenshood if you have one of the asymmetric ones. To be honest I wouldn't worry, it really doesn't seem that severe a problem to me.

And finally just to say you have some nice images there which I enjoyed looking at. I feel it's such a shame we don't talk more about our images, and the subject often only comes up when a problem occurs.

I could swear I just posted a reply a few min ago..... Guess not.
Definetly not a misaligned lenshood because I dont have one. Probably should get one. Thanks for the compliment about the images.

Are you doing your own processing? Or is it a lab?

Because you could be over agitating your film.... It's just a shot in the dark though.

I get it done at a local lab. C-41.

Forget photographing white walls etc.!

You can check if there is any vignetting the same way as we do when shooting large format: Look from the film plane with the shutter open. If you from the corners of where the film can see through the whole aperture opening, then there is no vignetting. If there is something preventing you from seeing through the whole aperture you have vignetting. If half the aperture opening is blocked you have one stop of vignetting on that aperture etc. If you confirm vignetting you can also check which is the largest vignetting free aperture is by gradually closing down the iris.

Use bulb and be careful not to poke your nose through the shutter whole while you release the trigger ;-). This was my way of saying be carefull not to touch the shutter.


(I hope it's not filter vignetting, I ordered an expensive B+W MRC yellow filter for my Nokton 40 f/1.4 just the other day)
