    Re: Show off your Large Format camera!

    Intrepid 4x5 on an unnecessarily large and heavy tripod.[/QUOTE]

    that's funny! My first thought was "that looks like more than enough tripod!" That wagon/trailer looks pretty stout, too.
  2. Re: Use of X-ray film: technical discussion with example images

    I don’t think a red laser would be a good choice for a darkroom light: too bright, too focused. Lasers want to be linear. A few watts of laser light would be extremely dangerous because of the...

    That's a very handsome camera in a nice setting from what I can see in the background. Looks like the camera has a lot of movements and enough metal etc to lock up well. I imagine it is a lot of...

    I love the coffee table camera! I've re-used all sorts of things in the pursuit of photography (and astronomy) to keep the costs down and for the joy of re-using things. The bellows looks great. ...

    Mammography film also has an anti-halation layer, which can be helpful, too. I vote for pyrocat-hd: it is helpful for non-silver UV contact printing. Light at the start or the end of the day or...

    Daniel, that's an amazing set-up! I imagine that is a lot of fun to use. I've only tried a few LF portraits with a Busch Pressman D (4x5), Sinar (5x7) or an 8x10 field camera and have had v. mixed...

    Re: Which are the fancy lenses??

    Sounds like a reasonable approach. Once you get going in 4x5 you might want bigger contact prints and then those lenses will seem a lot "shorter." I got to borrow a 75mm (I think that was it) for a...

  33. Re: Use of X-ray film: technical discussion with example images
