This is an experiment combining p-Aminophenol(ates) and Ascorbates (Vit C).
All the experiments are done on PolypanF.
The intention was to use less VitC than the usual formulae.
(reason : Rodinal/R09 1+100 only contains something like 0.6 g/L pAp developer, why use
several grams of VitC, with a high risk of fog and not so fine grain.)
(All the next amounts/weights are for a 250cc developer.)
I used 0.5 g VitC in combination with R09 1+100 1+200 1+250 and 1+500 -- I also used it in
combination with 4, 6 and 9 g instant coffee. (the pictures at the Ursel Castle are made
with the 9g.
I call these developers VitRo 100 .. 500 and VitCa 4,6 or 9.
It has to be noticed (visible with the Rodinal combination) there is no single trace of
oxidation (against the air - the reduction of silver salts works as normal, even stronger).
(Agfa claimed the darkening of the Rodinal during development is a result of the anti-halo
layer, this is only partly correct (simply because films without this layer also show this
result).
The VitRo developers contain :
3 g Soda (deca) .. Na2CO3.10H20 (= 106 + 10x18 g/mol - to calculate the mono etc..)
(this is needed to neutralize the H's from the Ascorbic acid, otherwise it will
take the OH's from the Rodinal/R09 and turn the developer ineffective).
0.5g VitC
2.5 - 2 - 1.25 - 1 cc R09
2.5cc of a 2.5% solution of Borax. (finer, rounder grain)
Example above is made with the VitRo 250.
Developing times : (PolypanF)
VitRo 100 12' 80iso
VitRo 200 20' 64iso
VirRo 250 25' 100-125iso (example above)
* VitRo 500 40' 64iso
(*) to be calculated : enough developer for the silversalts on the film ???
-----------------------
The VitCa is trickier, because the acidity of the coffee.
I start with 4g Soda (deca) and add 0.5 g / g instant coffee.
VitCa 60 = 7g Soda (deca)
VitCa 90 = 8.5 g Soda (deca)
After the water, the soda, the VitC (0.5g) I add 1cc 0.1% solution of KI (Potassium Iodide)
The VitCa 60 shows less contrast than the 90, perfect for portrait ...
Developing times between 50' and 60' push the PPF about 2x in the 90.
The 60 after one hour seems to reach 64iso (but I only tested with studio light, outside light
needs to be tested).
But should make excellent developers, with fine grain and great tonality and the ability
to push the film without burned-out highlights several stops.

At the Snaptic Developer Conference I took tons of people shots but this one of Wired's Brian Chen's funky sneakers was my favorite one. Day 147. May 27, 2010.
The developer for the legendary Kodak Technical Pan film. I found this packet (or rather, a whole box of them) about to be thrown away at a camera store.
Darwin CBD, Northern Territory, Australia.
A typical Darwin scene, where developers hold sway.
Some roads may be wholly or partially blocked for days or weeks.
An interesting side issue with exponential development is the almost parasitic growth of the traffic control industry, largely staffed by overseas backpackers (mainly well educated Irish female 20-somethings) who can earn 6 figure salaries.
they both love fixing and remixing things [whether they're broken or not :-]

Was a surprise, shock and altogether unsettling to find someone from my project, visiting foss.in !!

Highlights of this conference in July in San Bruno included an excellent lunch, and very informative presentations on some new YouTube applications, such as Animoto which I used several times this year.

Mae Delta Digidol 2 yn gynllun hyfforddi rhan-amser dros 6 mis ar gyfer wyth o raglennwyr/datblygwyr er mwyn:
•Gwella sgiliau gwyddonwyr cyfrifiadurol amatur a proffesiynol gan eu hannog i ddatblygu eu gyrfaoedd ymhellach o fewn y diwydiant Cyfryngau Creadigol.
•Llenwi’r diffyg sgiliau enfawr o ddatblygwyr gwe a rhaglenwyr gêmau sydd ar hyn o bryd yn mynd i weithio y tu allan i Gymru. Ariannir y cynllun hwn gan S4C a TAC, a cefnogir gan Skillset Cymru â’r ATRiuM. / Digital Delta 2 is a six month part time training scheme for eight programmers/developers to -
•Enhance the skills of existing amateur and professional computer scientists and encourage them to further their careers within the Creative Media industry.
•Fill the substantial skills shortage of web developers and games programmers whom currently take up employment outside of Wales. This scheme is funded by S4C and TAC, and is supported by Skillset Cymru and the ATRiuM
My newest tests with a different homemade developer. Yeah, it started with tea, what I’ve decided to call “chai-lenol.” The rest of this mysterious concoction? Well…
It seems I’m getting a lot more visits to my ‘stream of late (thanks all). The past few days have seen my stats go up more than double my previous high for any past day. I’m really curious to learn more about those that find me, maybe are also interested in homemade developers or experimental photography techniques/processes/equipment. So, please don’t just lurk, drop me a comment, so I can find your stream too!
Let’s see if that motivates enough people. Lol. If I get good feedback, as I hope, I’ll post the entire recipe of this strange brew. Believe me, there are one or two ingredients in this that you prolly wouldn't guess! Basically, I’d like like to use this amazing flickr community to help each of us grow and learn experimental photography techniques. I hope many of you also wish for the same.
Cheers.

I get a fair number of comments that peeps wish they could view images larger… while I maintain that only my contacts can view my large images (I generally upload at least 800px images on the long axis)… a quick workaround I might suggest is to view my photostream as a slideshow. Works well for me. this is frequently how I view others’ ‘streams, and it will put a large image on black. : )

on 01 jan 2010, i began my journey w/ a new flickr group i've formed, ~365: experimental
the idea is that i strive to push myself daily; experiment, learn, & develop my photography skills further by exploring techniques, ideas, and experiments. hopefully, some of you might consider joining and we can work on our journey together!
