post alternative techniques

No problem at all. Will hope to make more, inc. of actual flowers. This was a first attempt on large format with reversal development, and a stress-test of the printing process, since pretty small and detailed. Currently making another using red rose petals as emulsion; this will take a week or more to expose. Have another sheet of 10x8 film to reversal process now also.

Thanks for sharing your spinach anthotype process. First description I have seen of the process. Interesting that it is a positive process.

Another from me, this time an argyrotype I'm delighted with.


That Secret Stillness



Original exposure and development (one of my earliest 10x8 exposures)

Asham Meads BBOWT, Otmoor, Oxfordshire

Chamonix 810V
Nikkor-SW 150 f/8
Ilford FP4+ 8x10
¼" f/32
Rear and front tilts forward, down angle on Arca Cube head
No filters

Pyrocat HD 2:2:100 in BTZS tube
10'30" for N (5min prewash in distilled water; 1min acetic acid stop bath; 10min fix in TF4; 1min sodium sulfite hypoclear; 30min wash)
NB this was before I adjusted my alt-pro dev times for a certain style of printing after moving to Stearman SP810 trays, so dev time is probably .

Print:

Thanks for derails!

Many thanks. Now float-mounted and framed. Looks great, one of my top results with this process.

Excellent, I'll agitate for a quick snap of it on your wall--I'm still up in the air about how I might present these (notional) alt-prints I'm thinking about, but have developed a real antipathy toward the acres of white matboard approach.

[DaveF]

Currently I actually have four framed up (including this one), ready to stand alongside me as I give a public lecture; currently on temporary display in my workplace. The Clematis print has been up on our dining room wall since lockdown.

[Ironage]

I like the floating mount. How do you attach them to the backing?

[DaveF]

Thanks: like this.

Ha, I think you need to find a way to get up to 16x20 negs for your florals.

Otherwise, thanks for putting the floating frame idea out there--for myself, I could imagine standardizing on "edge-to-edge" Pt/Pd prints in the right color of cradle...
