    Actually, I have done the paint with developer thing a number of times. When sepia toned on matte paper it looks quite good. I also played around with applying developer with a spray gun so that it results in a series of dots, which is fun.

    Cheers -

    Scratch that, forget what I wrote, noone steal my idea. I'm going to get a paintbrush and a bottle of liquid-light on the way home, and get practising my chinese calligraphy...
    hi dr c

    with coating your own you have an open slate. its much more versatile
    than pre bought papers &c ... once you understand how the emulsion sticks ( or doesn't )
    or hardens, ( or doesn't ) or ? there are ways of doing all sorts of fun stuff ...

    I think that there is room for all of these. After all, it is art and just about anything goes. The questions are whether you like it and then whether your audience / customer(s) like it.

    If it does not please the majority, then it is not what is going to be viable until after you die! this is the usual rule o art!

    Sometimes it is fun. Platinum print, 11x14 negative. Next time I'll keep Alex's feet in the image area!

    At least with LF landscape, a bad day of photography can still be a good day of exercise.

    Thanks for looking up the numbers on tape! Scotch Magic is a easy candidate for taping puddle pushers. For some reason I've totally forgotten, I had a couple of rolls of 850 when I started playing with emulsions and I settled into it as my tape of choice.

    One note: 0.9 mil of the 850 is the adhesive. That's one reason I like the stuff so much. I just count each wrap as 1 mil because I assume the adhesive mashes down to nearly nothing. I also have to assume the adhesive on Magic Tape is also about 0.9 mils. But, as said, "stressing the mils" isn't necessary. Vaughn's approach to carbon could be the role model for our work. He's a master of his craft, without resorting to expensive accessories.
    Customer service for 3M got back to me, as I also sent the question to them.

    They're stating 810 magic tape is 2.2 mils (0.056mm) instead of what I found in the data sheet I found. I guess if you want to be specific, you should measure the rod bare, and then with the tape on.

    Thanks for digging up the information. That puts Magic Tape even closer to 810. They certainly look like they are twins, side-by-side. 3 mils is about as thick as air. Really, though, the exact mils is not that important a variable. I use the same puddle pushers for all my coating. 10 wraps of 850 tape. Might be eleven or twelve on one of them. (I have five so that I can coat five 36" strips of film in one coating session, without stopping to clean them before I'm done. With film, starting with a dry puddle pusher improves the quality of the coating pass. With paper, it's not as important.)

    Anyway, what's important is the temperature of the emulsion while you coat. One degree C can make a difference there. It's all about viscosity. The lower you can go and still have a good, smooth flowing emulsion, the better the density and contrast in the final product (permanent caveat: "in my experience".)
