Rodinal uses up the oxygen in the air and in the water, thus exhausting itself even if kept in an accordion bottle. As such, you should be using up what you mixed at the time - thus, mix up 500ml and use it and discard the rest. Mixing up 1500ml and using 500ml mean the 1000ml of the developer is rapidly losing strength, even sitting in an air tight bottle. This is unlike most standard developers - once the water is added, it should be used within hours, not days.
The picture is under-developed because the Rodinal did not have enough strength left to fully develop it. The Rodinal does not settle to the bottom, it just exhausts itself.
2) Stand development is not a magical panacea. It can work fine on higher contrast subjects but when the contrast range of a neg is small it will look like crap. I really don't know why people keep trying to use these obscure methods when they don't work as well as the simple plain Jane ones. If you would have simply developed the film according to the instructions on the box bot negatives would have turned out fine.

Whoa! I had no idea! Thanks! I allowed my mixed batch of Rodinal to sit for a week before using it again. I guess I'm lucky I got any images at all!
I'm going to ditch the accordion bottle, and I'm going to start mixing up batches of developer for each tank of film. This should give me the most consistent results possible.
Should I be careful about how I store my Rodinal too? I was told that it's a good idea to put glass marbles in the bottle of Rodinal so that it's not exposed to so much air?
The accordion bottle has nothing to do with it, I use them for my fix/stop and they work well.
The most consistent results I get are from pouring water into my mixing container, letting the water sit for 2-3 hours and then adding Rodinal and stirring briefly a couple of minutes before adding to the film for developing. (My brother works at a water plant and explained to me they inject air into the water in order to lower the density of the water and have it move more freely through the pipes; letting it sit for a couple of hours allows the air to dissipate.)
well said.
For example, if you are trying to copy lithographic prints that have high contrast and very fine detail, then stand development may prove advantageous in the latter part of the development cycle. However, for standard shots on panchromatic film leave alone.
And in fact, disregarding the obvious potential problems which have been talked about many times, stand development does not typically produce as much contrast reduction as people think it will. It depends a great deal on the chosen developer. Further, people need to think about what sort of contrast reduction they are looking for, depending on how they will print and what kind of detail they want. Using extreme compensating development procedures in an attempt to compress a long luminance range into the "paper range" can often result in more loss than gain in terms of the printable information in the negative. You can, for example, end up blowing the highlights with too much compression - as counterintuitive as that may sound.
keyofnight - I was hoping you weren't writing off APUG completely but as you can see, there are some strong opinions here. Generally, if it works for you, do it! The difficulty most people have is that they see fads (stand development, water baths, obscure developers, etc.) that somebody uses successfully and then everybody copies, thinking they will have the same success. You see this in people following Ansel Adam's developer/develop times slavishly and then being disappointed their pictures don't look like his - you don't just find this in developers, when I was working in a camera store, I sold a $6k lens to a new photographer because he wanted his pictures to look like the one in the magazine and this is the lens they were using (I tried for 2 hours to talk him out of it, with no luck - it's currently for sale on Craigslist). I have done stand development, it doesn't work for me but I was glad I did it, if nothing else I now know what it does and what I do/don't like about it.
If it works for you (and you seem to think so), keep at it!
You're rightpeople do copy one another blindly, and they have no idea what they're getting themselves into. I think Caffenol is one of those trends that doesn't make a lot of practical sense, but it sounds like fun none the less. I can imagine it has it's place too, though. By the way: it's great that you were one of the camera store salespeople who tried to do good things! Most would've swindled that guy for even more money. (;
its funny that you say that about caffenol
i have been using it in one form or another since may 2006.
i strayed from the pack pretty quickly, stopped measuring anything
stopped doing the times / temps they said ..
and now roast my own coffeebeans for my developer
and add a wee bit of print developer ( ansco 130 ) to boost the contrast
and smooth things out. ( it costs me about 4¢ / roll to process )
heck, i was using ansco 130 as a film developer before 2000 ...
the thing about developers and photography in general
is there are a zillion people all telling you you should be doing " this and that "
because it is what they are used to, it is what they like to do and it allegedly works for them.
just experiment with your developer, and film and figure out what works best for YOU.
it might even mean you over expose your film a little bit and use a stronger concentration of your developer
if you stand develop, or leave at box speed, and agitate a little bit at the begining, or middle or end just to
boost your contrast.
the hardest thing todo, especially with website forums
is turn up the squelch and only do what you want, without the rest of the people telling you how wrong you are
and not listen to how all your film and prints will look terrible because you are doing it all wrong ...
good luck figuring it out !

I keep hearing about coffee developer, but I can't find a simple mix explanation, everyone says try this or mix that, I just want instructions and then I can experiment from there, can you provide basic how to?
It's sorta on topic right? Coffee is a stand process right?

sorry to hijack your thread !!
the easiest recipe for caffenol is this
Caffenol C
8 oz. water
4 slightly rounded tsp. instant coffee
2 tsp. washing soda
1000 mg Vitamin C (1/4 tsp powder)
it has to be cheap rot gut instant coffee
if you can't find washing soda ( sodium carbonate )
take BAKING SODA spread it on a cookie sheet and put in an oven
at low heat to purge the moisture from it and convert it to washing soda
vit c, well health food stores, ebay, photographers formulary, pharmacies &c can get it for you
i stand develop, and mix it strong ...
most people do normal agitation schemes ...
if you have a scale go to reinhold's blog
( http://caffenol.blogspot.com/ )
there, he has TONS of info, precise recipes and tips to make it all work
there are even people that just make the coffee ( as if they were going to drink it )
and don't use the sodium carbonate or vit c
and stand develop the film for a while ..
caffenol negatives tend to LOOK thin, but they print and numericalize beautifully ...
good luck !
john
No worries about hijacking this thread (; I've been thinking about caffenol for a couple years. I'd love to try it at some point.
Thanks for the encouragement, John!
