This may be an obvious question. But does using orange or red filters with 16mm Kodak Double X have the same affect as with 35 or 120 photography film stock? Can't really see any examples from Google. Thanks

Hello guys and gals, So, yesterday, while processing some Tri-X Super 8, something nightmareish happened during the second developpement after re-exposure : after 1 min in the 2nd developer (where the emulsion properly reacted and darkened), it slightly started to lift from the plastic and then it litteraly disloved into the developper : no floating gelatin flakes, just a plain black developer... The weird thing is that I already processed Tri-X this way, here is an example : https://vimeo.com/326184819 Here is my protocole, I have included as much info as I can : 1 – Soaking in a 25°C water bath. 2 – 1st Developer : Ilford Multigrad 1+9, 20min (continuous agitation on 1st minute, then 10sec each minute), 25°C. 3 – Hardening stop bath : Adox EcoStop 1+29 + 40ml/L of Tetenal Hardener. 6 min, 20°C, continuous agitation. (https://www.fotoimpex.com/chemistry/tetenal-hardener-to-be-added-to-the-fixer-or-stop-bath-1000-ml.html?cache=1564733928) 4 – Washing, runing water, 2 minutes. 5 – Bleach : Potassium permanganate 0,4% + Sulfuric Acid 10% equal part, 6 min, 20°C, continuous agitation. 6 – Washing, runing water, 2 minutes. 7 – Clearing bath, Sodium metabisulfite 6%, 2 min, 20°C, continous agitation. 8 – Washing, runing water, 2 minutes. 9 – Hardening stop bath : Adox EcoStop 1+29 + 40ml/L of Tetenal Hardener. 6 min, 20°C, continuous agitation. 10 – Washing, runing water, 2 minutes. RE-EXPOSURE : 2x1min 80W 1m in a white tank filled with water. 11 – 2nd Developer : Ilford Multigrad 1+9, 4min (stand), 25°C. The same solution I used as 1st developer. And that's where the emulsion dissolved.... Usually, after that, I use an hardening fixer for 5 minute, washing 10 min on runing water, rinse with distilled water, let it dry and digitalise with a Retroscann Universal. It's fastidious, but cheap ! Side notes : - Processing in Lomo Tank. - I know Ilford says not to use Ilford Multigrade for processing film (Universal PQ is recommanded instead), but through my test phase it was the only thing I had on hand, so I tried and it worked as you could see on vimeo. - I've never found any information about the shelf lif of the Tetenal hardener. As it is supposed to be mixed with Stop or Fix, I mixed it with the Adox Eco Stop to be sure I won't use an hardening bath tha is no longer working. Anyway, I mixed a new solution and it was still a disaster. - I use the hardener to compensate the softening of the emusion by the bleach. One bath before to strenghten, one bath after to reinforce. I thing the bleach isnt to blame, otherwise it the continous agitation in the clearing bath would have the same mechanical effect, so I guess it is a chemistery issue. The film is perfectly fine during re-exposure, bleaching is complete, after touching the film, the emulsion is normal. - I dont know why the developper is dissolving the emulsion on second use but work perfectly fine on the first one. So that's it, if anyone have an idea, i'm all ears ! Thanks ! Jérémy

Im new to the forum and have a long question, but I have read a lot of posts here before so I am turning to you all for help! I bought my first super 8 camera, a Canon 310xl a couple of months ago, and in January, I bought two cartridges of Tri-X reversal to shoot with. I am a college student, so I did not have a chance to shoot until last week, so until then I kept the two carts in the fridge to keep cool. So last week, I finally opened my first box of Tri-X and loaded it into my camera. I notched hack the cart so I could control the built in filter as well! I turned the camera on and pulled the trigger, and the film ran for about 30 frames before the film transport indicator in my viewfinder stopped running, indicating that the film was not moving. So i opened my camera and pulled the cartridge out and the film had snapped! The whole cart gone. So I chalked it up to maybe a faulty cart, so I loaded my second one. And you guessed it, the exact same thing happened! Both my catridges with snapped film. So my question: Why did this happen and what can I do to fix it? I don't know enough about yet to be able to figure out whats causing the film to just break. Did the film get brittle from being in my refrigerator too long? Or is something wrong with my camera, is it too fast? Is something wrong with the takeup hooks? I just don't know. I have called Kodak about getting replacements, but scared that the same thing will happen again. If you may know anything about why my film is breaking after 30 frames I would appreciate your help. Im a college student, I can't afford just buying more film if I will never be able to shoot with it. Thanks!

I want to know the means of the letter "X" in the kodak Tri-X film. thanks!
