So what went wrong?
I went on a photo walk this afternoon with my trusty, old Konica TC-X SLR, and shot a fresh (unexpired) roll of Arista.edu Ultra 100. The meter seemed to be working fine but nearly all my shots were overexposed, regardless of the subject or lighting. So I'm guessing my meter is off. More disconcerting is the fact that the majority of images also have an excessively grainy appearance. I'm attaching an example of an image that I adjusted for exposure in GIMP. This is typical of the kind of graininess I'm talking about.
So any ideas what went wrong? A few possibilities enter my mind:
(1) The overexposure created the grainy effect.
(2) The age of my developer. I'm using D-76 that was mixed several months ago, but it hasn't yellowed noticeably, as I've seen with really old developer.
(3) I got a bad roll of film.
Or could it be something else I'm missing? I've used this film with excellent results in the past.Attachment 62912
Can you test your camera meter with a known accurate meter? Looks like this may be more a case of serious over- development rather than overexposure...you have some serious grain there!
I don't know what film Arista is, but I'm sue that the grain shouldn't be like that unless you have over cooked it considerably.
If your D76 was old the effect would be under-development, making your film too thin.
Couple of questions before I can try to even guess.
What does the film look like? Is it overly thin or overly dense in the image area?
What does the film rebate (outside the image area) look like? I know the numbers are there but is the rebate clear or if you look closely, can you see fairly even coat of what looks like an exposure to light?
You said your D-76 is older but how was it stored? In full bottle or less than full bottle?
Weird looking frame - almost looks infrared. I think the edu film is Foma 100. As Tony suggested, you should check the camera meter against another one, perhaps even an iPhone meter if that's all you have.
Were you giving exposure comp if most of these scenes were snow or snow and featureless sky?
The negs look really dark for the most part in the image area, although the rebate area is clear (other than frame numbers and film info). I didn't make any adjustments for exposure, although I got similar results with shots that had no snow or especially bright features (including ones I took in/ of shaded areas). I didn't try using a separate light meter, as I've not had problems with this camera's metering before (I even put in a fresh battery yesterday).
I believe Arista.edu Ultra 100 is, in fact, rebranded Fomapan.
The developer is in a dark brown bottle that's a little less than half full.
I always am GENEROUS with exposure with Foma films.
I rate Foma100 at 64 normally.
I've had D76 last out to 10 months but that was in FULL stoppered PET bottles.
Check your camera to see if the aperture is closing down at the time of exposure and the shutter speeds are reasonable.
One possibility is that a combination of over-exposure and under development (due to expired developer) resulted in very low contrast negs. When Gimp adjusted the exposure, it may also have pushed up the contrast, exacerbating the grain.
You are assuming the meter is faulty, but it could very well be that the shutter is off by 2 or more stops.
