    Re: Pyrocat-HD Part A precipitate

    It happened to me quite recently, but with Pyrocat HD in glycol that I made from scratch. There wasn't much of it, and initially it was made up of transparent/whitish particles, which have since...

    Re: Toning Van Dyke brown prints with thiourea

    Much to my surprise, I found the VDB print that I sepia toned a while back; it turned up when I was going through my stack of papers and film. Here's a scan... the colour you see is pretty accurate,...

    Re: Smoke smoke everywhere

    Watch out for the smoke! It's a much greater hazard then most people think. The smoke from the recent fires here in Australia probably killed far more people than the fire itself.

    Re: Show us your home made camera...

    Stunning! I wish my efforts were half as good.

    The huon pine must have cost a pretty penny.

    Re: Toning Van Dyke brown prints with thiourea

    I'm not koraks, but I did try sepia toning a VDB print a while ago. I used a finished print (fixed and dried) and followed the usual process: bleach then redevelop with thiourea. It worked, in the...
  7. Re: Rollei RPX25 extended red sensitivity example

    Thanks! I got lucky with a very clear sky that day.
  8. Re: Rollei RPX25 extended red sensitivity example

    This shows what the film can do with an R72 filter. (Apologies for posting a 35mm image, but it's all I have for this film.)

    This was at 80 ISO, but 50 ISO is closer to the mark.

  9. Re: Rollei RPX25 extended red sensitivity example

    RPX25 is Agfa Aviphot 80, the same film as Retro 80s. An R72 filter will produce pretty good IR images.
  10. Re: What is the current tech in alt printing light sources?

    I put one together using a BLB CFL, a box, and some lamp parts. It covers 5x7, doesn't get overly hot, and exposures for most processes are only 2 to 4 minutes. To cover 8x10 I'd need 2 CFLs and a...
  11. Re: Going crazy! Looking for a 3/8 female thread?

    There are also a few different types of tee nut, some of which don't have pointed spikes, which might make them a better choice. I've found the spikes to be problematic in many cases, especially when...

    Re: 8x10 film dev - what do you use as a process?

    BTZS tubes that I made myself, with press-on end caps and minimum developer. At the end of development I fix in a tray with the lights on.

    Re: Canon pro 1000 for digital negatives

    I successfully make digital negatives on a $50 HP printer. I'd hope that a printer that costs over a grand would be at least as successful. (In fact I'd expect it to be 20 times better!)

    Re: Enlarged Film Negatives Process?

    I've used the process described on unlinkingeye.com. Short review: the first exposure determines the negative shadow density, and is fairly easy to nail down. The second, "flash" exposure determines...

    Re: Print contrast issue

    I'd try a new set ofMC filters before anything else. They do fade over time.
  16. Re: Travelers: New X-ray machines WILL ruin your film

    A quick google suggests they've been in use at dozens of airports since 2016, just not in the US. Consequently, I think they're as dialled in as they ever will be :)

    Re: arista ortho litho film 3

    Check the film under a safelight; the emulsion side is a lighter shade than the back.

    Re: Question about Kodak 5x7 holder

    I have an old 5x7 Kodak film holder, and it's not only shorter than my Lisco holders, it's slightly thicker, too. That said, it's an excellent film holder.

    Re: Multicoating on a lens

    The coatings just reduce the amount of light reflected from the glass surface, so if it's just a spot with no coating on the front of the lens, you'll get slightly less light passing through the...

    Re: Pinhole recommendation

    I've bought a number of pinholes from an eBay vendor called fireseller66. They've all been very good quality and reasonably priced.
