Morning glory (Ipomoea sp.).

Left: Lumen print made by contact printing the plant on Ilford Multigrade fiber-based paper, exposing to the sun for 15 minutes, and then scanning the print. No developer or fixer was used at this stage.

Right: Scanned original lumen image (on left), was then post-processed in Photoshop. Image was flipped horizontally and inverted. Minor tweeks made in contrast, color, and sharpness.

This represents the ten zones, with black and white points set at each end in photoshop, from my 2 print tests (both based on iPhone images of prints in final wash before drying down), set against a zone 5 grey background. As this easily shows, the first print is N+2 and the second is N.

What it also shows is that Zone 5 has printed quite dark (probably more like Zone 4; on drying the brown turns to grey black so this will darken further) so may suggest that I shift my film exposure time up by one stop, to rate FP4+ at 64 when wanting to produce negs that will print well as Argyrotypes with more texture in the shadows.

I may well still expose at 125 for scanning purposes, given that on 10x8 one step extra time can be quite significant.
