    So far, this is best channel for darkroom printing I’ve seen so far. His how to print RA-4 (color prints) helped me. I had a bunch of roller processing tanks, bought from someone who used to have a photography store. I had no idea how to use them until after watching his channel. Thanks!

    I love your channel. As a darkroom printer myself, it's my favourite resource. I have a Dahle guillotine and it is excellent - recommended. I think it was about £30 second hand.
    As an aside - I've been using a 1960s Durst Laborator 138 condenser enlarger for a year which has been really great to use. Recently I picked up a non-working mysterious Durst UK (Pavelle) 402 colour head from 1972. I've gutted it and replace the halogen bulbs with LEDS and new wiring (as it was shorting anyway) and it lives again. I'm not sure I'm getting a full range of grades but certainly getting 1 to 4. So now I can switch between condenser and diffusion colour heads. Great fun!

    Love this channel. Love the detailed explanations. Can also recommend the Art of Photography (the early videos + artist series).

    So glad I found your channel! Been watching your videos all week. You've inspired me to get back into the darkroom.

    Congrats for the channel.Thanks for everything you share.
    Is it possible to use the kodak enlarging scale instead of the step wedge for calibrating the color head?
    best wishes

    • @TheNakedPhotographer
      @TheNakedPhotographer  4 года назад

      By enlarging scale I assume you mean the round density wedges for determining exposure time? I don’t believe so since it doesn’t show enough steps to make an accurate judgement.

    If I don't have a step wedge do you think I could just make a step tablet by making a test strip with no negative in 1/2 increments?

    Thank you so much for this video. It is the best darkroom resource by far for people starting to print now. Will you be interested in creating a printing course? Especially with a color enlarger to print bnw

    Is your transmission 21 step guide the 1-3/8" x 9.5" or the 1/2" x 5" guide from Stouffer? I have a 120 film size calibrated transmission step guide that I could put in a negative holder and expose on a small sheet of paper, or I could contact print it. Would that work as well as your step guide? I have a Beseler color head.

      I use a Kodak step wedge, though I have a Stouffer wedge somewhere. I contact print it.

    Have you considered replacing the enlarger’s fan with a Noctua fan or any other computer silent fan?

    • @TheNakedPhotographer

      There aren’t any with the right specs or connections that I can find.

      @@TheNakedPhotographer By the way it was not a complaint about the noise, just a thought. In many cases you can change the connections, simple rewire, etc. I have seen a similar approach for the drobo 5d (a hhd thingy). very very easy... I know about it for 6 years, still original fan in my hdd enclosure :)))
      A new fan, more silent or maybe with asymmetrical blade design I think would complement well the nice beast (De Vere).

    • @TheNakedPhotographer
      @TheNakedPhotographer  4 года назад

      The noise is less important than being vibration free, otherwise my images will never be sharp. These are also larger than computer fans I’ve seen since they have to cool down four 300 watt halogen bulbs. I’ve found replacements, but they are listed as industrial fans, not computer fans.

    Have you ever considered combining Y and M filters the way you get always equal exposure? Like 0 = 85Y + 10M, 2 = 40Y + 45M, 4 = 10Y + 75M... not sure wether from 4 it doubles as standard ilford filters. But this method seems more user friendly.

      @@TheNakedPhotographer not split grade. just combination of certain amount of Y and M simultaneously set in the head to achieve always the same exposure time when switching from e.g. grade 1 to 3... just not to have apply any time correction. Saves some time and calculation e.g. when making stripes test for finding suitable contrast.

    • @TheNakedPhotographer
      @TheNakedPhotographer  4 года назад +1

      What I mean is, I intend to make a video some time in the future comparing a single filter dial for contrast vs the two dial method.

    There were two (one each side of 2) that looked like they should have been moved a stop further up/down. Putting it down to video compression and youtube compression. There were a bunch of Gen-X and Gen-Y watchers that started counting Sesame Street style on the second row.
    Funny thing, there was a video game pre-roll ad that had a mature rating on it. The M rating logo stayed on the screen till the skip. I still laugh a bit at the opening. My inner 12 year old thanks you.

      It must have been compression as you said. In person it is pretty clear.

    I found a table in the documentation for my Dunco enlarger which has the values for the color and the time adjustments needed. Only issue is, that there is no 00 grade in there, just 0 to 5. And the values for yellow and magenta differ a lot from the values I found in the Ilford documentation for the multigrade filters.
    grade color time
    0 110 Y 1,8
    1/2 90 Y 1,6
    1 70 Y 1,5
    1 1/2 30 Y 1,3
    2 - 1,0
    2 1/2 30 M 1,3
    3 45 M 1,4
    3 1/2 55 M 1,5
    4 95 M 2,0
    4 1/2 130 M 2,3
    5 150 M 2,3
    Any idea what might 00 be like?
