    Love the content. Fascinating process. Could have done with the background music about half that loud so I can hear you but not have so much additional.

    Здравствуйте, посмотрев, Ваше видео, я вспомнил об одном химике и фотографе Сергее Михайловиче Прокудине-Горском, он тоже делал цветные фотографии, более ста лет назад, в Российской империи.

    Good work! With all the time waiting for the paper to dry between steps, how long does it take in real time? About a week?
    Thanks for posting this!

      Thank you! From pre-shrinking and sizing, to laying down the final blue layer, a couple of days. I have made a print in a day, but only because I already had the paper prepped beforehand. 🙂

    Hi Andy,
    Reminds me of my old colour separation days back in the '70s. I am wondering what filters you were using on the front lens to generate these images? Or am I completely wrong with the process

      Red 25, Green 58, Blue 47. I show more in a previous video, where I was practicing with 4x5 film... th-cam.com/video/4v8z-VHQTFM/w-d-xo.html

    Looking at that bellows sag and the position of the lens, I don't know how the image is getting to the top of the negative.

      I had already made the exposures, and removed the strap on the bellows that keeps it taut. Take a look at the 1:00 mark. At the top of the bellows, you can see the unconnected strap.

    Hi Andy, how do you clean the brushes and surface each time they were applied with chemicals?

    • @analogueandy8x10
      @analogueandy8x10  9 วันที่ผ่านมา +2

      I clean up with a sponge, using water and a bit of Vit C in it. I have to admit, I'm going through a lot of Vitamin C, but it's worth it.

      Sadly, no. I was a subscriber since the mid 90's. That magazine taught me a lot. I have many editions going back to its first season, 1979. Contemporaries contributed articles to it, such as John Sexton, Phil Davis, Howard Bond, Bruce Barnbaum, and others. Digital started to take over its pages in the very early 2000's. It died about 12 years ago, or so, like so many great photo magazines. I want to go through all of them (too many!) keep the good ones, and recycle the rest.
