I would suggest another method for bleaching film, using far more common and safe chemicals. This is a 2 part bleach, using 4 common ingredients: Part 1: Copper Sulfate, Salt, and Citric Acid. Heat 800ml of water until it is lukewarm. Mix 50 g of copper sulfate, 50g of salt, and 5g of Citric acid. Add water to 1 L. Mix until all powders dissolve.This solution is mainly CuCl3, and will dissolve aluminum, so be aware of this. Other than that, it is safe to handle, and only basic chemical safety precautions need to be taken. Part 2: Ammonia 1+4. Regular 5% cleaning Ammonia works well. Ammonia is a somewhat dangerous chemical, but as long as you follow all directions on the label, and don’t mix it with any other chemicals, you will be fine. Although mixing part 1 and 2 should be avoided, if they are mixed, the reaction does not release any harmful gasses or chemicals. Replace the dichromate bleach step with 5 minutes in part 1, and 3 minutes in part 2. Other than that, the process is the same. I hope this helps!

DUDE I LITERALLY HAVE JUST STARTED SEARCHING FOR THIS THIS WEEK AND THERE ARE NO VIDEOS AT ALL. Thank you so much!

This is the best educational video for Super 8 starters!!! Thanks for your effort!!

Excellent video. Owen's instructions make it easy for anyone to process reversal film the right way.

Thank you. This was extremely helpful

You can hook the draining tube onto the tap to wash back the film with running water and pollute the chems less.

great video🎥😀

Спасибо!

Interesting technology but no way could I ever do that in my current set up. Nice to know the method and option is there, though.

Very good, thank you and I am a customer.

Is that the Colonial Belle on the Erie Canal!? Are you guys based out of Fairport?

I guess the distilled water is because you live in a "hard water" area where the tap water is full of minerals and all that stuff. I live in a place with relatively soft and clean water like as an example limescale is never an issue in my house for stuff that use water like washers and kettles.

You didn’t use a hypo-clearing agent? Any reason? Thanks

Thanks for this, I always wondered if there was an at-home method of doing this. The only thing I don't understand is why would you slice the film down the middle? And why don't you see us seam down the middle of the film when you're running it through the projector?

you can safely use KMnO4 instead of dichromat

Anyone know the shelf life of the bleach and how many rolls of film it can do

The internet suggests a 100W light source for a proper second exposure. I only have a 24W bathroom light tube. Does that work as well? And do I have to make a longer second exposure with only 24W?

Could I develop Scala 50 Adox with these chemicals ?

All I've been doing is dumping the film into a #116 Paterson tank with non-toxic Caffenol. I'm even too cheap to buy new film. I buy old color 8mm Kodak film and shoot at f/1.9.

Excellent video and teaching. I have the lomo tank, shot some black and white reversal film but I just need the chemicals to make them at home. Would you recommend the CineStill Film CS2 Cine Simplified ECN 2-Bath Powder Kit to develop B&W Reversal film at home if you can't get the chemicals shown in the video? Thanks so much.

always wondered how develop at home really would like to get in to super8 soon

I've mixed up a batch of Kodak D-94a for Tri-X Super 8. However, Kodak's data sheet says use the first developing bath for 90 seconds and the second for 50 seconds? Are these times accurate for Tri-X Super 8 developed with D-94a in a Lomo tank?

Hello thank you for great video I have a question, is clearing bath you are using in your video the same as stop bath??

Why are you using dichromate bleach, considering other far less toxic bleaches are available? Is there any advantage to this over an oxidising bleach like hydrogen peroxide or potassium permanganate?

is there any 16mm black and white film that would use chemistry that still photos would use? I wanted to try and load 16mm film into a 110 cartridge and then develop it at home.

We never used gloves in school...

Would this chemistry work on Kodachrome 8mm to process it as black and white reversal film ?

I guess you are using a Fomapan 2x8 100R 10m spool. Can I use the same quantity of developer for a 30m spool or do I have to use it 3x concentrated?

Is that bleach solution reusable? If so, how many reels can you get out of it? Also, what is the proper and safest way to dispose of it?

I am a little confused. You are using the same developer for both steps? And once you bleach it you can pull the film out I'm normal light between steps? Can this be done with any film that has a good clear base?

Looking into a clearing/stop bath, i was told to use a mixture of water and sulfuric acid, and that you can simply use water, and run it through the tank a few times, but using sodium sulphite? That's sounds odd. Sodiumthiosulfate, or plain hypo, is the main ingredient in the fixer, and those two baths take care of very different jobs. I'm confused. I know that sodium sulphate and sodiumthiosulfate is not the same thing, they share big parts of the names, and the differences can't be too major.

Right, what type of quality do you get from 8 mm compared to copying to 720p? In other words, it a perfect scale for 8 mm.

Hello , im kinda late to the party here . I have an AgfaChrome (color) and i don't know how it's supposed to be developed , would you be so kind to help me out?

Hi. I think tank is most expensive thing in all this stuff. But how much cost al ingredients to developing. Obviously if you gonna develop more than one film, the price will be decreased. But for start how much do I need spend?

How do you project colour negatives?

Where do you get your potassium dichromate?

Can the mixed bleach be used more than once? Thanks

Those tanks are so expensive.

Everything cool, but why do you have to dry the film on a drier thus risking scratches and dust, I dry mine directly in the spiral of the tank, just use a fan to do it quicker.

What would be the official name for this developing process ?

All of chemistry can reuse ?

what ASA does 8min at 68 F give?

How did you remove the Remjet?

nah I'd rather just pay $20. yeah it's really cheap around here

Does this work with kodachrome 40?

If you want to get a roll of film scanned, let me know! Happy to help you out for all you do for the community! WWW.FRAMEDISCREET.COM Frame Discreet Instagram @frame_discreet Cheers! ♥ 🤓 Justin Lovell Associate Member of the Canadian Society of Cinematographers
