"Hi Roger,

"Thanks Roger, all very helpful. By the look of it H&A did make extensive use of their large camea obscura - or more accurately, travelled extensively using it, getting as far south as York. I am now wondering something else, which is; why my print…"

"Hello James, Thank you for the reference - I must look it up to see where he found the information. Just checked the Glasgow set and sure enough, a whole run of Linlithgow, in one case on small and format but all the others large... and looking…"

"Thank you Michael and Sara, and great to hear from you!
This does explain why before the Autumn of 1844 he had a camera that could do justice to the Scott Monument. Looking through the negatives of St. John's Free Church again I realised that only…"

"Thank you both... and don't worry, I am still guessing at the moment, as you will see.
What I posted is a detail from a calotype in the Hill and Adamson collection in Glasgow University Library. It is a very small part of:…"

Can anyone tell me the specific camera being used here? The date is around 1843. If the man at the back is holding a darkslide (and not just steadying the camera) then it appears to be a very large format.

Dr. Joe Rock commented on Michael Pritchard's blog post Radcliffe Observatory 1842 negative donated to Bodleian

I thought it would be interesting to see this as a positive.
