    Re: DOF on 8x10 vs. 4x5?

    Magnification. This is important, because many DOF tables and equations leave OUT magnification!

    Re: Need Packard shutter solenoid mod

    I build this intervalometer for my Bolex (after seeing Koyaanisqatsi) using only a servo and off-the-shelf servo 'tester.' This may give you ideas.

    Re: Durst L1840 Parts Needed

    The focus on the Durst L1840 bellows is electronically controlled with a PWM system that ensures the upward focus and downward focus will be the same speed. There are 10 or so pages about the...

    Re: Durst L1840 Parts Needed

    I'd be interested in seeing that. The usual L1840 focus motor is driven from electronics in the ECU1000 that sits between the legs of the L1840.

    Re: Durst L1840 Parts Needed

    Looks like you have a hybrid enlarger. Some Durst literature calls that part the 'camera' (not the 'cairrage' or 'head') and it is from a L1840. Looks like they grafted that onto a L184 chassis and...

    You can also estimate using (magnification +1). So if you are at 1:1 then 1+1=2; you have 2 times the coverage and one-half the angle of view. For example a typical 150mm lens at 1:1 will cover 8x10...
