  1. Have Model III, make following observation in attempt to minimise

    impact of vanishing globes on Minoxers.

    Chasing the Fischer bulb seems an expensive way to achieve what is

    essentially a simple matter of placing the collimator lens in a proper

    relationship to the bulb.

    Put another way, forget the bulb and mount the collimator lens 10mm

    closer to the non Fischer lamp using a simple 10mm high tube. Such

    tube can be made to lock onto the existing collimator support with

    minor or no alteration. A disc placed on top of the tube can provide

    an identical collimator lens mounting to the existing plate.

    REMEMBER, if you do this, DO NOT TO FIT the Fischer bulb when using

    the 'tube' else it will likely hit the collimator lens or the element

    will be so close as to possibly cause it to crack from heat.

    Bulbs need not cost USD50 ever again, that I note is what some hopeful

    is putting as the first bid price on ebay. Done neatly the enlarger

    need not stray from its original condition.

    It would have been nice if the collimator plate could simply have been

    inverted - that would have moved the lens 10mm toward the lamp. But

    the internal lamp shield wont allow this - it would have been so neat.

  2. Just a note on scanning.

    There is a site on the net which shows scans at 2700. 4000 and

    6000dpi. Whilst 4000 appears the max initially - because grain shows

    - the 6000dpi scans still give better detail. These scans are of 35mm

    film stock. But it does look as though scanners are nearly at the

    limit and, incidently, digital cameras are generally not in the

    running.

    As for the direct scan suggestion I think its catch 22 situation. If

    you project onto a screen you have the noise of the screen to contend

    with. Conversely if you remove the screen you are scanning the film

    direct anyway.

    Hope these comments help discussion.
