Wow

Nice print!

Fantastic documentation

One question

How did you digitize?

[DaveF]

Thanks!
Apologies: Nikon D800E and 85PC-E tilt-shift, tripod. 2-frame stitch. Print just lying on large photobook on floor (dried flat quickly in this warm weather we're having).
For printing, basically following Christopher James' instructions. UK Fotospeed sensitizer comes in handy 50ml bottles, though larger sizes are also available.

Thank you!

I knew you didn't use a cell phone!

Clematis Argyrotype

Always a delight when these turn out.




Original exposure details:
25th April 2020 3:15pm
Chamonix 810V
Nikkor-W 300 f/5.6
@ilfordphoto FP4+ 8x10
760mm bellows extension, with extension board
(Working distance 550mm)
1min 20 seconds f/16

Stearman SP810 tray, Pyrocat HD 2:2:100, 12’, 21ºC
Acetic acid stop, TF-4 Fix, Hypoclear, wash, Ilfotol rinse


Print:
31st May 2020, mid-afternoon
28ºC, relative humidity 45%
3ml Fotospeed Argyrotype sensitizer + 1 drop of let-down Tween 20, Bergger Cot320 11x14" paper.
Paper dried for approx 30 mins before exposure.
8'15" in full sun, Lotus 12x16" frame
5mins wash in 1.5l distilled water + squeeze lemon juice
5mins wash in 1.5l tap water
3mins wash in 2% hypo (4.5tbps to 1.5l tap water)
1 hour final soak (30mins face down, 30mins face up) in 3l tap water. Dried on clothes rack for a few hours, then dried for 2 days under boards (usually a week, but unseasonably hot weather!)

My eagerness to get working has tended to get the better of me: sometimes I expose the paper too soon and too much of the print washes off. Now I know that about 30mins in warm conditions is enough time to make a good print.

Let me add my thanks! You've piqued my interest in this process. I guess here in the US, we would have to mix our own sensitizer. I'd be interested to know if anyone has done so.

Many thanks. I don't recall the details, but the premixed sensitizer has a good shelf life. Certainly better iirc than 2-part old cyanotype (the only other alt process I've yet tried).

Thanks Dave. That’s good to know. I just have to look into sourcing the chemicals.
I should have also said: great image!

[DaveF]

Many thanks. Definitely one to put in a frame!

I was going to do some more today, but it's raining; shouldn't have said anything about the weather! I have a UV lamp for indoors but the exposure times for it are frustratingly lengthy, and I don't like to use too much equipment for these in any case. The wow of the simplicity!
I'm still learning, and it can be hit and miss with choice of negatives. Since I have a minimalist setup I enjoy the experimentation, and am also now recognising how more accurate I need to be in my film development for this process than simply for scanning.

Thanks Dave. That’s good to know. I just have to look into sourcing the chemicals.

Here is a 5x7 contact printed cyanotype. The monster growing in the park behind my condo.

Hello, Dave -- except for the stone fence I would have guess a location shot for High Plains Drifter (Mono Lake, CA). It gives me the feeling it was a warm August day on the Isle of Bute, tho I suppose a warm day might be 22C.
It has a good balance to it - determining how much sky vs foreground can keep me under the darkcloth awhile.
