Kodak C41 2.5/5L kit and Fujihunt 5L kit - from a Bellini 1L user

When getting the developer up to development temperature, do you just put the bag in the water bath as-is

Why would you heat the entire bag? Just drain the required amount of developer into a bottle and put that in a water bath. A lot more convenient than having to handle a wet, floppy bag and having to wait for potentially several liters of developer to come to temperature when you only need a few hundred ml.

My understanding was that the OP uses 1 L bags and 1 L development tanks, so he'd need to put the whole bag in the bath. I was curious how that worked. I usually use a 2 reel tank and I would do exactly as you suggest: heat what I need.

Thanks for clarifying, that makes good sense!

I never warmed up (hehe) to the wine bags.

You're welcome. I'm pretty new to trying to handle chemicals at home (other than 1-shot b/w stuff) that have lifetimes short enough to have a real impact on the economy of their usage. When I handle chemicals at work, it's using proper laboratory equipment (I'm an analytical chemist). Despite some chaff, there is a lot of "wheat" tips in these forums! Thank you for your many useful contributions as well...

Sorry missed that question. Once I mix all the chemicals for the entire 5L kit, I separate them into 4x 1L light-tight air-tight wine bags, and 2x 0.5L wine bags.

My regime is like this for the 1L working solution:

- Use Paterson 1L tank (3x 135 or 2x 120 rolls)
- Use full 1L chemical
- Time compensation for color developer (in minutes): 3:15 for rolls 1-4, 3:30 for 5-8, 3:45 for 9-12, 4:00 for 13-16
- I did not bother to compensate for bleach and fixer
- Pour 1L chemical back to the wine bag, squeeze out air and foam, cap

And repeat the above for next few rolls. As I said I use up 5L over about 11 months, so use up 1L every 2 months or so.

Could you please give a link to the wine bags you use? (I'm in the EU, but hopefully will be able to find the ones you use somewhere.)

Much appreciated!
Your input from your professional background would certainly also be highly appreciated on the forum; please don't hesitate to comment whenever you run into some 'chaff'!

Mine looks like this, they can stand up on their own.

That's a nice design. The bags I purchased will not be as convenient. I'll figure something out though... The ones I ordered are this style:

Thanks, they look more practical!

Yes, if one is going to put the whole bag in the bath, these look great. I plan to dispense what I need into a PET bottle, so I won't have to worry about the lack of support that the bags I shared will (or more appropriately, will not) provide...

 

[lamerko]

This may be a dumb question, but how do you fill these bags?

 

[ChrisGalway]

The ones for fruit drinks/smoothies etc have a screw top and a funnel is provided with them. (That's why you don't want "wine bags" with taps!)

 

[koraks]

For the wine bags there's a stand that can be purchased with them (although it's easy to DIY one) that the bag can be suspended in, and a regular funnel can be used to fill it.

I did a "wet" run with water to test all of the procedures I knew what I would have to do priort to putting chemicals and chemical exposure of me at risk. These are terrible. Well, not intrinsically, but I do not have the right tool to remove the tap easily and re-filling them is a nightmare. The dispensers are so tight that would require superhuman strength to remove them without a tool. I'm using PET bottles in 1 L and 0.5 L size for now. Developed my first two rolls today and it went well and the negatives look good. The final rinse left a few stains (I can probable rinse in distilled water to remove), but I was proud of my first C-41 negatives ever and using this kit.

I 3D printed this one and it worked well. Too bad refilling these blasted bags (at least the version I purchased is nearly impossible).

The new stop loss bags are pretty good.

Excellent!!! I've used (full) PET bottles for many years. The 21st century soda bottle is a technological marvel! Think about the extremely low gas permeability required to store carbonated beverages.
Price is right too!
I love developing color film! The good old days of formalin fixer, nice!

Everyone should try this. Well done!

Currently printing a rack for securely holding 4 x 500 mL PET bottles in the warm water bath.

Just out of curiosity - why use so much material for something that only acts as a spacer? I imagine that takes ages to print, but you could achieve the same functionality with about 80% less material and thus a far quicker print job.

Indeed, it is 270 g of PETG. I was looking for a hex patterned side wall model that was already designed that was also parametric and couldn't find one. This model was interesting. It was a web-modifiable file that I believe was based on OpenSCAD. Other than the fact that I would have preferred a hex side wall, I liked the design enough and valued my time in Fusion more than I valued the extra 100 g of PETG that I would have saved... I don't mind that it'll be more stout with the solids walls, perhaps it'll last longer that way. Didn't really care about print time - I check in with the networked camera from time to time, so I was happily doing something else.

 

[koraks]

Ah I see; I always just fire up Fusion, make a shape and then if I feel it's too much material, take away stuff by making holes in it, LOL!

 

[sperho]

I'm not very good at modifying others STL files...

 

[koraks]

I see; I honestly never really try and just make what I need from scratch.
