    Re: New Computer Time...

    First computer I ever had was something my dad brought home from some military surplus whatever, so I'd have something to work out my itch to tear apart and dissect gadgets, instead of resorting to...
  2. Re: What is the Most Difficult Large Format Photography

    Inside a nuclear reactor facility "hot zone". It's been done. Remote servo-style view camera controls, of course, and not using film per se for the capture.

    Well, I guess the only way I'll be able to obtain equivalent results to some of those recited here is to take sandpaper to the elements of my own Dagor. No, it doesn't have quite the tangential...

    Re: Beautiful Contemporary Daguerreotypes

    Compelling portraits regardless. I too am skeptical that what is being shown is D-type. But I admit I don't keep pace with any potential modern tweaks on that process. Mercury is not my cup of tea.

    Re: RA-4/color darkroom printing in 2021

    It's like any other relatively basic darkroom process, including regular silver-gelatin printing black and white printing. You can make it either as simple or challenging as you wish. It takes a bit...
  7. Re: Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    Go to McMaster Carr. There are industrial rubberized abrasives available for both Dremel and small die grinders, a big selection of these. These are generally superior to conventional Dremel options....

    Re: Provia 100 vs Ektachrome 100

    I already stated it, and it's a distinction that's been important for decades, but now not as well recognized by many because many traditional applications of sheet film have been replaced with...

    Re: Plastics question for film developing

    Developer consumption is quite a factor in realistic choice of methodology. I use only 500 ml of fluid per roll of 120 in a Jobo hand inversion drum, and only 400 ml for up to 12 sheets of 4x5 in a...

  12. Re: Fujinon EX 135mm enlarging lens not fitting 53mm lens board.

    Gotta be careful with those little Dremel points; they can dig in unevenly. Use the largest diameter abrasive cylinder they offer, and lower the RPM a bit. As far as sanding afterwards, I'd rather...

    If this is the focal length you like for 4x5 applications, no need to look for a different brand. Fuji is highly reputable.
