I’m very confused with the ‘quality” of the last batch of four paper negatives.
As normal I cut up a 8x10 piece of paper from a box of Ilford MGIV RC de luxe pearl multigrade paper using a roller cutter to give me four “4x5” sheets and loaded two double dark slides. [I assume that the sheet of paper chosen was as per the box label, but as I was given the box of paper there is no certainty]
The paper was cut and loaded in a bedroom with closed curtains and an orange darkroom light. The only difference being that a new carpet had been laid in that bedroom.
After wet chemistry processing the paper negatives were scanned using a HP 3520 all-in-one printer.
Two of the resulting images are ‘scattered’ with dark spots and part of another image is coloured brown!
Image01 and image02 (both infested with dark spots) were taken sequentially on a tide line with a gusty wind blowing at right angles to the camera line of view. Image02 is a small section of the full 4x5 positive – It is noticeable on this image that the “spots” are often in threes and a triangular pattern. In both cases the exposure was 1s and f11.
Image03 (coloured brown) was grossly underexposed but scanned with extreme brightness and contrast setting and the resulting image inverted to make a positive. This image was taken through a window with long exposure and large aperture setting.
The lens is a xenar f4.7 135mm fitted with a 40.5 to 58mm ring onto which is screwed a 2x yellow filter and a lens hood.
Paper negative processing was as usual - Jobo tank and 2509 holder using Ilford PQ Universal developer [1m], Ilfostop [10s], and Ilford rapid fixer [1m].
Any and all help welcome.
Regards
Tony
