I was using a changing bag to develop my B&W film and it wasn't the easiest to use especially when you have 3 film and a large tank. I had completed some research soon changing tents and released how expensive they were, hundreds of pounds. Then came across the Calumet own branded tent which was £50 Bargain. I used it the first time the other day and it was spot on, makes it easier to load the films and find the parts, it is well made and extremely portable with it folding into its own bag. I managed to buy it with a special offer which gave an additional 20% off, well worth registering to get notification of any offers. Great company to do business with
