Diana F+ processing problem.

[Callum Green]

I bought a F+ with the money that I saved during Christmas. When I received the camera, I didn't have any 120 lying around, so I followed a quick guide on the net, and 'modded' it to take 35mm. I shot two rolls of this (Klick max 24 expired 07) and everything seemed to be working fine. I went into a light sealed room, took the film out, wound it back into the casing, and took it to Boots (UK) to get developed.
Once I received the rolls back, half of them where completely black, the other half didn't develop at all.
I've loaded another film into the camera, wound it on with the back off, and checked to see if the shutter release was working correctly. It all was.
I was wondering if I had done any steps wrong, and that it was my fault about the films, or if Boots had just miss processed them.

Thanks

Check to make sure the little aperture lever under the lens is set properly.

When you say "half"... you mean half of each roll? Or entire rolls, in quantities equal to half?

[Callum Green]

Thanks for the replies. It waas during the snow here in the UK, and I was shooting on the "sunny" setting, due to all the light reflecting off of the snow. The Klick film is ISO 200, so I assume the apature was set way to high.
As with the film, I realised that I hadn't taped a certain part, and the last few frames slipped.

What would you guys suggest to shoot on? The cloudy one all the time?

Thanks

For bright snow with 200 speed film, use the sunny setting (approx. f22).

Thats what I used, and all of the images are under exposed. Hmmm

[Jon Shiu]

Is the film mostly clear (ie underexposed) or is it black (overexposed)?

Note that there is also a P (pinhole) setting that is f/150, which would be very underexposed.

Its all under exposed, as they were basically clear. I think that the pinhole setting might of been selected for a few, but I know I had it on sunny for the rest of them.

Thanks

Well, the basic exposure for bright snow scenes with ISO200 film would be about f/22 at 1/200, so assuming your camera is shooting at 1/60 at f22 (sun symbol), you should be about 2 stops overexposed. I would look for some other type of error.

Thanks man, I'm scanning the negatives in tonight, so I what they've turned out like properly. Thanks for your help.
