Brightwell Barrow, Wittenham Clumps 8x10 FP4+
The third exposure made on first outing with new Chamonix 8x10.
A test shot, primarily: will want to return when crops are fully grown in any case.

Chamonix 810V
Nikkor-SW 150 f/8
Ilford FP4+ 8x10
1/15” f/22
11º down angle from level on Arca Cube head, about 1º extra front tilt, rear tilt back to vertical – equates to large amount of front fall and front tilt
Wheat crop metered about half a stop below 0, N development, home-developed with Pyrocat HD 2:2:100/BTZS tubes, 10mins 30secs (my ballpark figure for a dev time that will also suit most alt-pro contacting printing).
Bit of vignetting cropped out from corners in sky – not very surprising given implied movements.
1) Scanned this one at 2400ppi. Clear that, for my 15inch MacBook Pro with 16GB Ram, a Grayscale file of at least 1.5GB is too large, esp. if I then convert to RGB for toning... Reverting now to 1600ppi max.
Two faults that were obvious on screen at full size, if not in detail on ground glass at x4:
2)
f/22 is not sufficient depth of field to provide proper sharpness to tree in background. I was concentrating more on wind and shutter speed, but f/22 looked fine.
3)
sky almost uniformly grey. Lots of editing in Photoshop including via platinum toning to get sky contrasty. Should have used my yellow/orange filter, still with my 5x4 kit. This would, though, have heavily affected the shutter speed, of course.
Exposure and development, however, still clearly otherwise fine I think. But if I'm making exposures for contact printing as well as for scanning, I need to get my filtration etc. spot on all the time.
On a very positive note, however, 8x10 has not been, on the basis of four sheets so far, the dust spots/scratches nightmare that I had feared. For this exposure I didn't even bother despotting it. On the next sheet this was far less time-consuming than usual with 5x4 or 120.
