You might want to recheck yr dilution of part a and B It should be Part A 1 gram of potassium permanganate to 250ml of water Part B 13.5gram of sodium bisulfate to 250 water When ready to use (it does not keep well), mix part B to A .

@ I’m going tomorrow to pool supply store and try another brand of sodium bisulfate. I’ll let you know how it goes. But the first part worked so image turned almost completely “black” after1st developer. Thanks for the quick answer

@@cipriandragoi9166 check the ingredients list of the oh reducer and may sure it only has sodium bisulfate in it. All yr best to yr next attempt.

@@AnaloguePT I mean, right now I'm using Sodium Bisulfite ⊘ Non-GMO Gluten-Free Vegan OU Kosher Certified - 50g/2oz from Modernist Pantry brand. Do you think is good ? this is what is say in the description : Anhydrous sodium bisulfite is an anti-oxidant and widely used food additive to preserve freshness and color in vegetables and juices, particularly green vegetables.

Glad you think so!

@@FrancescoFucito-r2j thank U for watching!

@@cipriandragoi9166 depending on how big yr papers are and how much silver need to be bleach off before the bleach got exhausted. Both chemicals are relatively inexpensive so do mix a bigger batch if you need you are going to shoot more in the same seasion

@ I’ll do 5x7

@@mikelalmazor181 R you using the same developer and bleach as in the video? After the bleaching, do you see like an almost white paper as the image would be bleached away. At this point, re exposed it to light (like to the lights in the bathroom)like for maybe 30 secs and do the second development again.

@@alainmijngheer I mixed it myself or if U buy a b&w reversal kit then it will hv the bleach.

@@mr.mahathir89 probably due to it clear base. U can try to develop using d23 developer

Yes I would say underexposed by 3 to 4 stops and develops normally. Yes the key is the emulsion should face as it has no reflection

i just did a threaded hole in fusion360. m9x1.25. maynot be an exact fit but works for me.

The full tutorial is here ruclips.net/video/WKwSdiP-dmQ/видео.html

Thanks for watching!

Glad U enjoy it!

Me too. Probably will try a contact print first

@@AnaloguePT share your results. 🙏🏻

We probably can but I have never try it. What would be the application for it?

Developing photosensitive film to make a resist mask for electroplating. Essentially cost a piece of metal with photosensitive film and expose it to light. Where it’s exposed to light the film hardens. Just want to get some super small details and light projection seems to be the key

@@Federico84 this is designed to be used with a 545 holder. Theoretically the concept can be adapted for a film pack camera I guess

​@@AnaloguePTwhat do you suggest for making a pack film?Also,I m Total newbie and don't have a dark room,how can I work with all of that?I own a polaroid and a Kodak ek Old camera

very nice. great work by your father. i reviewed the book here ruclips.net/video/Ldk-kyjNjCg/видео.html

@@mistercheah yeah I designed it based on the dimensions of the spacer that came with the back. It will be a bit narrower. Will update if I were to change the design.

@@8storeytree thanks for coming. Hopefully more events soon

My pleasure. Cheers

You're welcome!

the rounds per minute is based on the car wiper motor. i just use it directly without any speed control. otherwise you will need to use some speed control circuit or some gear to change the RPM

Yeah on some days it's really good

Thank U! Glad you enjoyed it

Oh it was in another one of video on Reversal processing for slides but here it is Part A 1 gram of potassium permanganate to 250ml of water Part B 13.5gram of sodium bisulfate to 250 water When ready to use (it does not keep well), mix part B to A .

If shooting as negative then best to expose at 200

By sight, i taped the negative to the paper on one side and lift up the neg to inspect. Different brands of paper may give U different colours. Ilford papers seem to be pinkish while foma tends to be more grayish

@@AnaloguePT Very cool, I would guess that you fix those papers afterwards right? Atherwise they are not stable for long.

@@codysergeant1486 the image will be gone of U fix it. So either scan it or put inside some thick book and it will d Fade off slower

Hope U can try it and make it better!

Yes just removed the ground glass frame. Totally reversible if one day I decided to use back the Kodak camera as it is.

Yes they are cheap though sometimes different batches seems to behave differently. Yeah most b&W film can be reversed processsd processed to become slides
