Caffenol Out of boredom

Has anyone seen a formula for Folgers Freeze Dried Instant (of course regular not decaffeinated)? That would be an easy why to do this.
 
Apparently, Folgers or whatever - it's not the caffeine but caffeic acid that does the job so any instant does the trick. The cheapest is the best it seems. It is made with the robusta sp. and has more of the acid than the expensive stuff. For once, cheapest is best!

John , Murry is right , most of what I have read say the cheap stuff work the best. But if you have Folgers use it , it is used and mentioned quite often.
 
To try and keep this tread going, here are a few shot from some Arista 400 Premium using the Delta STD recipe. 8 min's. Shot from a new to me Konica 1 3rd version with 2.8 lens . First the scanned images. The second image is what happens when you use to much coffee and not enough Vitamin C.

The middle image looks like what happens after the 3rd espresso of the morning. :) Is that what you mean by too much coffee?
 
Here is one more shot and two images of the camera

Yes.
Really it was just a dbl Exp. My mistake using the new camera, you have to mash a button on the rear of the camera before it will allow you to advance the film . But you can still cock and fire the shutter. :bang: you just have to remember what you did or didn't do .
 
I took a roll of Delta 100 to Tom's house and did my first caffenol development. Well, Tom prepared the soup and I just develop as usual with a tad bit more agitation than my Rodinal routine.

It's always fun to try a new way to develop film.

The result is quite creamy, though on some of the frames, the corners are a bit fogged:

But nothing that a little nudge on the vignette slider won't compensate well. (It'd be a bit more challenging in the darkroom, but that's another story).

More from the same roll on my journal.

Eirik it was your thread that pushed me over the top to try caffenol. I was looking for that thread the other day but couldn't remember where I saw it.

Thanks tom
 
Thanks for the advice, Tom, I'll try that. I've been following several caffenol blogs, and Ezzie has produced some truly spectacular images over the years, imho. Really interesting process that I'd like to explore more fully.

Here's one that took a lot of pp:

 
My suggestion is that, if you are going to use caffenol, then use the formulas from caffenol.blogspot.com.

They are in grams and ml and will make sure you get consistent results, i.e.. none of that "teaspoon" and "pinch" stuff, because you end up with the old "it worked for me" when others whine and fail when they try to replicate the results. ;)
- I do see that the delta recipe has ml and grams in there, but the teaspoon stuff is still in there. The recipes at caffenol.blogspot.com has a lot of trial and error and notes for a whole heap of films, so you should be better off using that place as a source imo. I think Ezzie base his trials on the caffenol.blogspot.com, so he is probably a real expert on those and possible quirks :)

I think the reason why caffenol has a (undeserved) bad rep, is that the previous formulas has been based on measuring units that are useless and that the data-material hasn't been consistent at all. caffenol.blogspot.com really does provide a lot of data and experience and the recipes are easy to follow.

You cannot get a sensible amount of ascorbic acid by using "teaspoons" and "half a cup" as measurements. :)

How did you Americans get to the moon with this foot-pount-per-quare-inch-and-a-teaspoon-of-a-quarter-inch-gallon stuff? :D
