    Re: Horseman L45 With Wide Angle

    I have the same camera and lens. Things are a little tight without a bag bellows so worth the investment. Great camera.

    Re: How is Large Digital C-prints made?

    My wife still prints with a Lambda for the few artist clients still getting C prints. She said they haven’t experienced supply issues yet, but I imagine they stock a lot of the same emulsion.
