I wonder if there is an actual problem such as uneven development that OP is trying to solve?
I use metal tanks also and takes probably 15 seconds or so to fill and empty. I've never seen any problem in the end result. I keep my development time greater than 5 minutes as that's what Kodak datasheet says. I find, if I tip the tank a little and aim at certain point in the opening, AND regulate the speed of pour, I can get good flow rate. I try not do it too fast where it starts to "burp."
If this question is a result of reading somewhere, uneven development could result from slow pour in/out and OP is not seeing an actual problem, then I'd not worry about it so much.
wrong thread... delete
I have no problem filling tanks. It takes 15 sec to load but also takes 15 sec to drain so my dev time is the same each n every time... It all works out. Besides a few seconds really makes no difference.
Just be consistant!
Do with that information what you will, and if you DO have problems with uneven development, this could be a factor.
Welcome back BTW, Chris! :)
I don't get this uneven development argument at all n i have been developing film for 50 years with perfect results.
I can understand if your development time is very short, less than 3 min, then 15 seconds may impact eveness. Hey, come on here, it taskes the gelatin about a minute to absorb the chemicals n get to work.... It's not an imediate on contact reaction.
But if you are developing for longer times, 15 seconds is nothing to fret about and won't make any difference in the final result.
Uneven development?... Dilute your developer a bit.
Those who DO have problems might, though, and that's my point.
I had uneven development problems. And I cured it by lowering the film into an already full tank. If somebody else can benefit from that info, I thought it would be handy if somebody provided it.
And if you read my entire responce, you'd see i gave advice learned from 50 years of experince.
Your rediculous solution simply defeats the purpose of using a daylight tank... WHY??? Duh hugh?
So why are you having such problems?... Might stem from your lack of reading comprehention, no common sense, or you've been watching too much television.
Btw the photo of the pines is beautiful!
