  1. Re: Shooting multiple formats (4x5 & 8x10) - separate lens sets, or one for both?

    I started with 4x5, but there is a little overlap in the lenses with the 8x10. The 210 is used for 4x10/5x8 using a mask, the 270 G-Claron works with rear movements only. The 450mm Nikon is 8x10...
  2. Re: What system for 8x10 in a Jobo 2500 tank?

    Yes, you need to use paper drums with the internal ribs and the cup light trap to do 8x10, so strictly it would be a 28xx series. I use one of these for my 8x10 work as it works with my CPE2+.

    If...
  3. Re: The F.64 BPX Back Pack does not seem to have a place for a tripod. What do people

    If you are not using pouches on both sides, you can use the loops to strap on a tripod. It just about works with my CF tripod, but probably would not work for
    a heavy or tall unit. It is handy to...
  4. Re: How many holders do you usually take with you when shooting?

    Well, 4x5 plastic holders weigh about 200g each, and the 8x10 equivalents around 620g. I presume a 10x20 holder is heavier. After the camera, tripod, lens exposure meter and a bag to carry it, film...

  6. Re: Whay are some of my images sideways?

    I like the idea of making mounting jigs - easy enough to define a block and subtract the volume of the piece in software. One thing I do with larger objects is print a slice or portion of the whole...

    Re: Designing and printing a 4x10 holder

    Looks well thought out, and very well executed. Are the screws self-tapping, or using heat set sockets? Are the white inserts printed, or tape?

    You have to be careful of two things with 3D printed boards - the flexibility and the density of the plastic. Density should be OK with black layers of 0.6mm+ top/sides/base of the print. Flexibility...
