Dear Mr. Shanebrook, Thank you for sharing your insights on the trade-offs behind T-Max design. Your explanation of how the original speed goals evolved—and why—was especially illuminating. With the disappearance of Technical Pan, and later ultra-high-resolution films such as CMS 20 / Copex...

Unfortunately, I don’t have a lightbox, but I’d say the images have low contrast likely because I used POTA. Most of the examples I found online were developed with standard developers and looked far too contrasty in comparison. The darkest areas of the positive appear more like transparent...

You're right it actually taught me a lesson... I had put a lot of effort into those shots — tripod, long exposures, the whole deal. Luckily, I found an extra roll tucked away in my drawer.

I found that retro 80s or rpx25 work really well at iso 50 1:100 rodinal for an hour.

Unfortunately, my Adox Adotech IV had expired 🥲. After fixing, my CMS 20ii negative came out completely transparent. On the positive side I developed Orto Mikrat Direct positive exposed at 0.375 iso in POTA and that worked really well!

Hi, I'm going on a hiking trip this weekend and I want to bring my last roll of CMS 20ii with me. I have noticed that sometimes when shooting at iso 12 and adotech iv I get muddiness in the highlights. Could POTA at ISO 6 be helpful ?

I know nothing in terms of developers. I read that sodium sulfite dissolves grain. Can I modify POTA for more accutance ? I do not care about being able to store the developer fr a long time.

Ok so I bought sodium sulfite this time. I will develop a new roll this weekend and post the results.

ok good thing I asked, I just realized I confused sulfite with sulfate 😅 Thank you for your answer

Hi, I tried POTA for the first time a few days back with Aviphot 80 (Rollei Retro 80s) exposed at iso 40. My negatives turned out almost transparent. Has anyone encountered a similar issue ? I'm trying to understand what went wrong. I read that phenidone was prone to oxidation, if I...
