Dry: An Update

If it’s been rather quiet on the dry plate front it’s not because I’ve not been busy. Indeed, I’ve used most of a box of the Speed plates in the last ten days or so. So, why the silence? A picture might help here.

Notice anything odd?

The example on the left of the three is something I’ve seen before as it happened on my first plate and I’d put it down to user error. However, chatting to Andy who owns the plate holders I was using, revealed he had a similar plate so unless we were both making exactly the same error, be it with loading or seating the holder, then the likely culprit was the holder. We were certainly not using the same camera and lens!

The issue with the other two is different to the first plate, suggesting perhaps that one holder was used for the first and the other for the second two examples? The shape of the light leak, whilst not exactly the same, is very similar too. There’s clearly an issue so some more thinking and testing was called for.

In the case of all three glass plates, used on two different days, each was exposed using exactly the same set up and at the same time as a sheet of 5×4 film. The sheets of film were all absolutely fine. Looking at the scans above shows that the exposures used for these plates were good too which is a small positive from this. I’ve plenty of experience with 5×4 and whilst it’s not impossible I think I can rule out loading errors. To be sure, I used one of the failed plates to load both holders in daylight and could find no way to mis-load them without it being very apparent.

I’ve even tested the plates from the current box themselves. Taking a fresh plate from the box in the darkroom, staying at least six feet from the safelight and putting it straight into the developer gives a perfectly clear plate. What we would expect. Later that morning I used a plate in an Ilford Obscura pinhole (no holder required) which also confirms the plates are probably fine. The other factor in favour of the plates not being the issue is that my first fail was with one of the plates that Andy gave me initially and not from those that I bought for this project.

As a final test I exposed a further plate with a newly-purchased double plate holder. It was a very bright, sunny day and the holder was positioned with the slide pointing upwards as is my norm for vertical compositions. There is the suspicion of an ingress of light, perhaps from where the slide goes, but nothing like the pattern on the earlier plates. I will remember to cover the plate holder in future just to be on the safe side, although that’s something for another day. Taken with everything else though this final test does seem to suggest that there is an issue with the holders I’ve been using.

Speaking to Andy last night he thinks he can see a split in one of the holders so we’ve both spoken to the manufacturer and explained our respective experiences. He is sending replacements to Andy and is going to test the original holders. I have to say the response from him has been first class and very refreshing.

So, a disappointing end to this phase of the project not to say an expensive one as I’ve used one and a half boxes of plates getting to this point. Undeterred though, my new double plate holder arrived last week and I am going to be ordering another box of plates today, I go into the next phase with some confidence.

Despite the issues I’ve demonstrated that I can accurately calculate exposure and I’ve had valuable hands-on experience in handling the plates. The developing methodology I’ve adopted is working well and I’m pleased with the results from the HC-110 too. So, loads of positives and I genuinely believe that despite the setbacks and disappointments I’ve learnt a lot so far. The next stage is to concentrate on compositions and locations that will utilise the glass plate aesthetic to its full.

That’s gonna be the tough part!
