Thanks Miha! That's super helpful.

Also curious about placement of the Unicon 50 for 35mm or Unicon 85 for medium format if anyone knows.

Hi all,

I just picked up a Durst Pro on Craigslist as my first 4x5-appropriate enlarger. The challenge, however, is that it was largely disassembled and the previous owner, who was using it for...

I am thrilled to have my first purpose-specific darkroom ever (in a basement rather than a temporarily converted bathroom), however I am having some problems with my new setup. The enlarger is only...

I am a little worried because the temperature is quite high -- mid 80s F some of the time, down to high 60s F when I turn on AC (it's a house in the Northeast with "ad hoc" / room-specific air...

Is it okay to refrigerate or freeze loaded sheet film plates? I am not getting out to shoot as consistently as I'd hoped -- film is in the plates for a month or two in the worst case -- and I'm...

Thanks everyone, they are definitely ferrotyping plates. Scratched and dented so I'm afraid I won't be able to experiment with them, but good to solve that riddle.

I guess this also explains why...

I got a fairly complete, serious set of darkroom equipment off of Craigslist about 10 years ago... over time I've figured out what basically everything is, but I'm still vexed by a set of ~11x14...

This is all very helpful, thanks everyone!

Silly follow-up question -- is there a way to support a long lens besides a second tripod? (looking particularly at the Komura lenses)

I am looking for the longest focal length lens on my 4x5. The challenge is that I am limited to 12" / 300 mm of bellows draw (black edition Intrepid). I am less concerned about weight, bulk, and...

@ic-racer It's a positive from my away-from-home "scanning" system -- 500mm on a full- frame DSLR pointed at a monitor. The main thing I am worried about is the dark spot in the top right corner (see...

I keep getting big splotches on the edges of my negatives -- it seems to be the bottom of the negative where water pools in the drying process. I am just air drying on a clip after a 15 minute...

I have a few photos from my first field outing with my first large format setup that have pronounced light leaks at the edges. I think they are from having switched the inner and outer baffle on my...

@Kiwi7475, yes it's possible, and I found another example on the board here with the same error. First time in 32 sheets!

One question re: the SP 445 -- it is still leaking all over when I try to...

Thanks everyone for the suggestions and comments!

I tried increasing agitation to 4 1s inversion cycles every 30s per the SP-445 instructions. The results were odd -- generally better for 3 of the...

Hi all, I am trying to debug some issues with my setup (started large format about a month ago)

I am finding that I am getting unexpected, splotchy variations in density in my negatives that vary...

This is exactly right -- it looks like painted PCB and it shipped at the end of June. Covering the whole lensboard in electrical tape "solved" the problem. I will be in touch about a replacement....

It is a #0. The light ring in the above photo is the space between the shutter and the circular stand-off in the front standard. The material of the lensboard seems weirdly translucent with a thin...

After re-seating my two lenses four times each and trying all combinations of electrical tape, I put a flashlight in the bellows and lo and behold the whole lens board glows. I feel slightly gaslit....

Hi, I just received my first large format camera (an Intrepid 4x5 Mark IV) after reading this board for several months and am trying to track down an issue with a light leak: In bright sunlight, on...
