NedL submitted a new resource:

(there was a url link here which no longer exists) - How to fix a solargraph

Solargraphs are usually ephemeral and kept in a dark box. Here is a simple method to fix them so that they may be stored and viewed safely in the light.

Ilford MGIV and Adorama VC RC paper emulsions contain ingredients that act like incorporated developer. If you put the paper into alkali solution, you will get some self-limited development, and the amount of development can be controlled by how alkaline the solution is. This development is complete in less than 20 seconds at room...

Thanks! Will definitely try this out with my next solargraph.

I think you've tried this with Lumen prints as well Ned?

Excellent idea and clear instructions. I'm gonna try this! I'll place a pinhole camera for about 4 weeks to do a first test with normal B&W photo paper. I'll also try a sheet of Harman Direct Positive Paper to get a positive analogue image in the first place. I'm curious to see if the DDP will work as a solargraph the same way as regular B&W (negative) paper.

I'm also gonna post a pinhole camera in my garden this week for the next WPPD 2015 on April 26th, 2015. This gives me 7 months to expose the solargraph.

I used strips of lumen prints to dial in the recipe, but I haven't done it with them since then. MGIV lumen prints "develop" a funky olive green cast, which could work for some lumen prints. I left those out on the shelf in the sunny window for the same 8 months and they were fine too. I think it could be interesting to try this with various toners...

I thought if the developer was weak enough this might work, so I started out with caffenol which is supposed to be a weak paper developer. I kept reducing the amount of coffee more and more and more but every time there was fog and the result was black after fixing. In frustration, I tried it in just the water with soda, and was amazed when the same thing happened. Then I reduced the concentration of soda more and more, but didn't find good control until I started adding the bicarbonate. With strips of lumen prints and rows of baby food jars, all I needed was some lightning rods and crazy hair and the picture would have been complete!

I'm gonna be a Mad Scientist this weekend. I've had a solargraph exposing for the past 6 months. I've got my bottle of Ilford Rapid Fixer, and gonna pick up some washing soda and baking soda on the way home. We'll see what develops... Muahahahaha!

And a little thread necromancy doesn't hurt the mad scientist image either. :D

I've only just found this link - just as Autumn and Winter approach and there's no light to do a lumen or solargraph,,,:sad:

But I've bookmarked this link and printed it out, so hopefully the next time there's a good bout of light I know what I'll be doing! :D

Hi Terry,

You can make a lumen print by putting it next to a window, even on cloudy days there is some UV. It might take a couple days but it will still work. Also, most CFLs will work... put it on a table with a CFL desk lamp for 5 or 6 hours....

Wow...

that's not much sunshine during the winter. But still, if you stuck a solargraphy can out for 2 months, it might get 100 hours of sun, on different days, and they can look even more interesting if it's not sunny every day. A bigger challenge is keeping condensation out of it, and I haven't solved that yet. It's no fun going to collect your can and finding it full of water up to the pinhole. I've made a couple with a "drain hole" stuffed with black foam ( hoping it will keep the light and bugs out, but let the water seep through... ) but haven't tried them yet so don't know if it's a good idea or not.....

Just wanted to pop on to say that I just tried this with my unfixed lumens--is still too soon to say about fading, but I defintely lost the gorgeous colors from the originals. Boo. I think I will try contact printing the original unfixed lumens to color paper next , why not? The lumens should be fine with a blast of enlarger light, its the sun I'm afraid of!
