I've been a photographer for over 25 years now and have
constantly battled uneven development. Your tubes give me perfectly even
development - and I am quite grateful. C. G.
It is rare to find a product as well thought out and as well made
as the BTZS Film Tubes. F. T.
I bought the Film Tube Kit and a Film Test per your
recommendation and have spent my time making photographs instead of
testing ever since. J. Q.
Simple, Elegant . . . Congratulations! S. W.
BTZS Film Tubes are legendary among large format photographers. Film
Tubes are a simple to use rotary processing system that works better
because of random two-axis manual rotation not found in any other
processing system. The tubes not only spin but wobble in the water bath
therefore agitation is truly random.
Now you can mix different films, developers with different processing
times and run them all in one run using a minimum amount of developer -
only two ounces per 4x5 sheet - for greater economy.
Benefits are:
- Even edge to edge development
- Low chemistry usage
- No rolling devise required
- Process different films and/or
different times in the same run
- Convenient daylight
operation
4x5 film tube kit includes:
- Tempering and holding tray
- Six 4x5 film tubes with caps
- Six extra caps (no need to pour developer in the dark)
- Illustrated instructions
