Product Description

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

οΎ 

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

Testimonials

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.

  1. BTZS 4x5 developing kit

    Posted by steve on 6th Jan 2014

    This kit worked great the first time I used it. This beats tray processing by a mile.


  2. Even negs, very first time.

    Posted by Eric on 4th Nov 2013

    This set up is great! It's simple to use and I got great, evenly developed negatives the very first time! I bought it so I can develop each sheet of film individually. The design of the btzs system makes this pretty simple to do. The components are also of high quality.


  3. Development Tubes

    Posted by Joshua on 27th Oct 2013

    Been using these for a couple years now and they provide a nearly impossible to mess up way to evenly develop sheet film for much easier printing!

    Highly suggested to large format photographers everywhere!
