Hi,
This is my first time developing B&W film. I bought a used 2 reels Kindermann tank. After struggling with loading film into these stainless steel reel, this question come up. There is no instruction go with the tank so I have to find answer here. I found one solution which is measure directly with the tank, but it's too late now. I hope you can help me with this.

Best regards,
Thang
 
Thang, that will be 450ml. Good luck with your developing. If it's your first time, just remember nothing is critical except introducing things in the right order and keeping the light-tight cover on the tank until the end of the fixer step.
 
Thank, I will try and let you know. One thing make me worry is when I loaded the film in my restroom, with all the light inside and outside turn off, I still kept my TV on. I don't know how much affect form this. But I will keep continue to see what happens. Lesson learned :D
 
Thang, I suggest you purchase a "photo changing bag"... It's a lightproof bag with two holes for your arms. With this you won't have to worry about ambient light.
 
I'm considering stainless steel tank myself. As far as I know the reels are not anchored in those steel tanks as in a plastic tank. So when developing just one roll of film I need to put in both reels - second will act as a spacer to keep the reels from sliding all over the place inside the tank. However I would only pour in as much chemistry as needed for one roll (250ml). Will it work fine or can cause uneven development?

I have a small one roll tank as well, but I usually wait until I get another one exposed and do two at once. If I had to do one roll in the two roll tank I'd definitely put the second spiral in there and probably use at least 300ml to be on the safe side.
 
This raises a question I have been wandering about.

Does it matter how much developer is used in the tank?
Of course enough to cover the reels and the correct dilution.

Does it matter if I would use lets say 500 ml rather than 300 ml for one real of 135 film.
 
Using noticeable less developer in a small tank than the nominal volume will expose the wet film surface to the excess air in the tank when inverting. This will cause bubble formation on the emulsion during every inversion and could cause uneven development in form of small round spots on the film.
 
But does filling the tank with more developer than needed have an effect?

I mean after all despite the same dilution there will be more developer in the tank. Witch will have less exhaustion than a tank filled with the same amount of identical dilution.

There is no effect if having "more" developer in the tank than needed. For example, the small LPL tank holds 250 ml for one roll of 135 film and the MaSuKo tank 500ml but there is no need to correct for the different total amount. The concentration is important only. Exception ... if you use stand developing where the absolute amount of developer ( for example 3ml Rodinal per roll of 135-36) is important.
