    Hi-

    My daughter is trying her hand at pinhole photography for the first time, and we're running into some problems with the developing. She did a mini-class last year, so she knows what they should look like. (she's 14)

    This is our first time at developing our own photos. She used the oatmeal box design for the camera, which she and my husband put together. She's using the resin-coated paper film.

    She's experimented with different exposure times, but every time we put it in the developer, it just develops into a smeary mess (different every time). We're using Ilford paper developer (liquid concentrated), which we mixed with water according to the directions.

    What could cause this? There are black and dark gray smears, and very little of the image. What we can see of the image (if anything), has pretty much no contrast.

    Any advice would be greatly appreciated!

    Thanks-
    Theresa

    Heya Theresa and welcome to ThePhotoForum. I merged your two identical threads so the forum remains uncluttered.

    Let's hope you'll soon find someone to give you a hand in developing pinhole photos. I'm afraid I am not the right person to answer your questions.

    (My daughter's 14, too, by the way).

    This sounds like it may be a problem with the camera itself. A couple things to check off.

    The paper has to be loaded and unloaded (at development time) either in complete darkness or under a safelight (amber would be preferable but a red safelight will also do).

    The pinhole in the oatmeal camera should be just bigger than pin-sized (about the size you'd make with a thumb-tack).

    The camera needs to sit perfectly still during the exposure and be completely light-tight except for the pinhole.

    The exposure time will generally be btw 15 and 45 seconds outdoors, depending on how bright a day it is.

    You should cover the hole before you pick up the camera to carry it anywhere.

    If you're doing all of that correctly, then we can talk development problems.

    smearing mess is not going to be very helpful to determine if this is a processing problem or an exposing issues.

    things that are out of focus may have that "look" of smearing. things blend into each other.

    can you post an example.

    Hi again.

    I'll try to get those photos posted tonight. Max - everything that you mention sounds about right for what we've done. We did notice that when we didn't have enough developer in the tray, that the areas it touched first turned really dark - kind of like a dark stripe though the middle of the picture. We added more developer, thinking that might help, but it did the same thing.

    I'll try to scan the photos and get them up in a bit.

    Thanks!

    Theresa

    when your "taking the photo" is the "camera" completely still? if it moves at all it will be blurry. also, make sure when you load the paper into the camera, it is loaded correctly{directly across from the hole}. alot of people will mis-align the paper.{happens ALL the time in my high school class}

    The camera was definitely still (sitting on top of our septic field cover with a map weight on top), and as far as I could tell, the paper was loaded correctly. It's not a blurring of the image, but big streaks. You can't really see the image at all.

    I scanned the photos (if you can call them that!)

    How do I post them?


    Thanks!

    pretty sure you have to upload to an image site first{such as photobucket, or putfile}

    then use the link it will give you and just copy and paste it into the reply

    how long do you develop, stop, fix, and wash?

    i think it might be chemical stains.
