Here's one of the pictures from the nearest drying screen:Snow Gum, Kangaroo Ridge, Infrared
Gelatin-silver photograph on Ultrafine Silver Eagle photographic paper, image size 19.5cm X 24.6cm, from a 8x10 Efke IR820 negative exposed in a Tachihara 810HD triple extension field view camera fitted with a Wollensak 159mm f9.5 lens and IR680 filter. Exposure time was 20 minutes at f22.
Titled, signed, and stamped verso.
This example shows the result of a 8x10 negative contacted onto 8x10 photographic paper. The black "verification border" resulting from the clear edge rebate of the negative exhibits subtle emulsion chipping. Emulsion edge chipping happens in ordinary processing but it is essentially invisible when the edge is white. For this image I cut an over-mat that hides the black border and 1 millimetre of actual picture all round. The full over-mat is preferred in many galleries. The photograph is titled and signed on the back (verso) and a separate wall card conveys the catalogue details.
When I want to assert the complete picture, black border and all, I'll contact the negative into the middle of an 11x14 sheet of photographic paper. Then the over-mat is cut to leave (say) 10mm of white space at the top and sides and 15mm at the bottom. The bottom space is convenient for titling and signing directly on the face (recto) of the photograph.
I suspect there are as many matting and framing preferences as there are photograph makers.
