    just got another three films developed and scanned to cd..... all the images are REALLY noisy (on the scans) and all the corners of the images (on the negatives) are all vignetted....

    Films were all ISO400, from various manufacturers and pics were taken on a combination of nice summer mornings, afternoons and nights (some with polariser, all with 1a filter)


    what's going on?
    what am i doing wrong?
    on previous films the prints have come out really well and the scans have just been a little noisy.... now they're all vignetted and really really noisy



    grrrrrrrrrr
    I'm ok with digital just seem to fail amazingly with film

    Hello captain

    ... a few thoughts:

    The negatives might be underexposed - or the film may have been badly processed. Have a local expert check them for you

    You mention using filters: ensure that a "step-down" ring is not causing this. On wide angles, even the filter's ring may effect that result

    Have you changed labs - or has the lab changed their technician (??)

    On balance, apart from the vignetting, i suspect the problem is your lab

    Locating a good lab, producing consistent results, can be a nightmare. Find yourself an expert technician and follow them

    Happy hunting!

    :)

    Thanks e_ :)

    just by eye... the negatives seem fine... i can't see some of the random marks on them that are present on some scans and i should be able to see some noise on certain pictures on the negs but i can't so i'm thinking the noise is from when they scanned them...
    I'm going to have a look for neg scanners and then hopefully i can scan my own at home...

    Nearly all the images are missing thier corners tho which baffles me... I have a 67mm lens and use no more than 2 filters (both at 67mm) so i don't know where the shadows are coming from... unless i'm not remembering properly and have used a skylight AND a polariser on most... (which is very possible ;)) I'll try one *or* the other in future and see if that solves anything.

    as far as labs go, i've tried 5 different ones with my last 10 films and I've not been happy with any, however i have recently found a 'pro' lab nearby so next time i think I'll forget about the cost and try them. :)

    Yeah, if you are stacking filters then that might the cause of vignetting. Also, if you are using a wide angle lense you should use a wide angle filter, so that the filter won't cause vignetting by itself. Just take some pictures with and without your filters and you'll know if they are the cause.

    The vignetting is on you, the rest sounds like the lab.

    As has been said stacking filters, particularly with wide angle lenses, causes this. Polarizers in particular are usually thicker than other filters. And you may not be able to see it in the viewfinder because most viewfinder do not show 100% of the image.

    I found vignetting on some of my pics when stacking a pol on top of a UV filter on a 28-200 lens when I was down around 28mm. When I put the filters on and carefully looked through the viewfinder I actually could see the vignetting, but I hadn't noticed it at all when photographing. The problem went away as long as I only used one filter.
