    well I got the glass today and out the sucker together, I'll be testing it out in the lab at school tomorrow.

    I'm going to have to find a new glazier local to me. Mine is way too expensive. 32.95 for (2) 6x8" 1/8" thick sheets of glass with knocked edges. ouch.

    But so far, my duct tape hinge seems like it will work quite well.

    I've got it wrapped up in a box waiting to be used, so I'll add pictures tomorrow of it in use. and report back as to how it works out.

    thanks for all the help guys, I really appreciate it.

    so,

    got the glass, built it, but I'm very dissapointed

    newton rings everywhere. And my glazier sucks. I asked for glass that didn't have any scratches, but I got two pieces back that had some nice little hairline scratches.

    I'm angry.... But after spending some nice green for these pieces of sh!t, I'm ready to bash heads in.

    and all the enlargers at school don't allow me to print full frame (with rebate) from 4x5. yesterday turned from bad to worse.

    otherwise, I held better focus across the entire negative WITH the glass carrier than without, but the NR's made my head spin.


    any ideas?

    I'm getting so hooked on 4x5, but I want to print with the rebate of the film, so the viewer(if they understand what the rebate is without telling them first) understands they're seeing the entire
    frame, uncropped. so they see exactly how I composed it in the 1st place.

    I think it adds a little bit of an artistic element too, not just another picture, etc.... but something to be different. cause I like to be different .

    You can get enlarger glass from KHB Photo in Canada, and they sell over eBay too. I got replacement glass intended for an LPL 4x5 enlarger - one plain bottom glass and one anti-newton top glass. I made a neg carrier by milling plastic, though mine was for a 4x5 scanner and it seems the scanner can see the texture of the AN glass However, in theory you'll be fine using AN glass in a diffusion enlarger.
    4x5 AN top glass

    A 4x5 negative usually lays very flat. You could just lay the negative on top a sheet of unscratched glass with a mat board cut out on top.

    No. Newton rings normally do not appear between the film emulsion and the glass, so the bottom glass need not be anti-newton ring glass. Also, to form Newton rings, the top surface of the negative must be firmly pressed to the glass.

    Just to be difficult, I find I get NR with Acros laying on plain glass; maybe its emulsion is smoother/shinier?

    oh well, I'll just have to scrounge up some neg holders(glassless) and file em' out.

    its ok though. I'll be only doing color darkroom work for contact sheets for now on after this semester. I don't have the time to do anything but contact sheets it seems right now. And scanning the film gives me the ultimate control I like to have.

    B/w though, I'll still stick to the darkroom for sure for printing my good stuff.
