Edible Film Developers

read a great book on photo chemistry....it said caffeine worked so I tried it....and no go

just started honey test #2 @ 80+ degrees...in at 7:35...gonna leave it in there a couple hours to see if it actually developed the first test or just stained it


kind of interesting...if a food develops film it just might be a sign that it's a healthy antioxidant...could be a new diet
 
wow, 80
i did that once and my emulsion lifted off the
plastic/film and went down the drain ...

sounds like a fun plan
 
only time my emulsion went down the drain was when I tried reversal BW processing with permanganate bleah followed by sulfite clearing bath
 
IT WORKED !!!!!!

ok, I am officially amazed....I was expecting failure...but it worked

Honey-110 dilution Bee for 90 minutes worked

so now the question is...was it glucic acid...or were other bizarre things in this goop I made?
 
definitely a bit of fog...the "clear" areas of the image are quite gray....but it still worked

perhaps honey in your tea + sodium carb. is the way to go
 
Ron - mushrooms have been successfully used to turn black and white
photographs into color ones, and that's probably a valid reason to outlaw them. Some of our California stereotypes are true, although nearly all the
remaining original hippies were netted some time back and are now
taxidermied in a Smithsonian 60's diorama across the aise from the tie
dye T-shirt exhibit. I wouldn't eat any of that either.
 
I suppose I can try pure glucose...but it's kinda more fun using an off-the-shelf ingredient since this is all for fun & not to replace The Great Yellow Father
 
I just realized something....

if glucose + sodium carbonate creates a film developer...and plenty of plants/fruits/vegetables have glucose in them...

how do I know which active ingredient is developing the film if the raw material has glucose in addition to other goodies?

obviously not many things have as much glucose as honey....but it's something to be aware of
 
what about aspirin? just read about a few developers that have either aspirin or salicylic acid in the recipe...but not clear if the aspirin is actually doing any developing or if it serves another purpose
 
It's a chelating agent used in developers to protect from iron contamination iirc. But looks like it could develop possibly. There's info on apug here and there, you'll need to google search it (salicylic acid site:apug.org)

Try it out, it's one of the things I've never gotten around to, but aspirin under going hydrolysis will form salicylic acid, or salicylates (within a base etc), eg similar to parodinal production method.

so sodium carbonate isn't enough?...would need to use Lye and let it sit for a while like parodinal?

It'll hydrolyse in water, but I'm not sure on the speed.

You completely misunderstand the chemistry here!

Sorry about that! Have to put things together from snippets of information

I know you can use Wine to develop film
 
Sorry guys, it was late at night and the topic is long and tedious. Maybe someday I'll post a long bit on this.

OK..today's experiment will be to use my lunch as a developer...

gonna go to the salad bar and get something to eat....and also toss some veggies into a separate container to grind up later & try as a developer
 
ok just poured the Saladbar-all into the tank @ 80F

spinach, red onion, carrots, tomato, red cabbage, red beans, blackberries, blueberries, etc from the grocery store salad bar

tossed it all into the food grinderchoppercutter thing until it was just mush...added water & heated in microwave.....then added 3+ tbsp sodium carbonate...and Voila -- the pink/red liquid turned green

now just gotta wait and see what happens

...I was originally thinking of tossing in some red wine...hoping the alcohol might help extract the goodies from the veggies...but snce I've heard red wine works...I'll test wine separately

so far the only red wine dev recipe I've found includes vitamin C...but I'd rather test red wine alone
 
Please write this down:

On March 1, 2012 at 10:36 Eastern Time it was scientifically established that tossing your lunch into the blender is not an effective way to make a film developer.



that is all.
 
I usually do not toss my developers.

Good luck. But just as side note, wine will develop film so it would have upset the results.

right, that's why I left wine out of the test of mixed veggies

so many things work on film -- at first I was amazed when something worked...now I'm more surprised when something doesn't work

gonna try cheap red wine later today
