Rollei A110 film camera

I use Rollei A110 camera, with ASA 100 A110 color cartridge from Frugalphotographer.com I also have two Pentax 110 slr cameras

The film in Rolllei A110 is propelled forward by four springs at the back door of A110. I find that the film does not advance smoothy. I use a small screw driver to pry out the four springs a little. After doing this the film advances more smoothly.

conrad_hoffman, wrote 16X, ha! Not happening. Actually 300x already achieved 300x, 16x is a piece of cake You can look up old issue of American photograpy: Philip Priedell in in 1946 November issue of American Photography. Friedell used a two bath developer containing Benzotriazole. He use Dupont sound track film with very low film speed--Weston 8 to take picture with this low speed film and developed in his two bath developer, he got result equivalent to Weston 300 to Weston 460 a amazing speed boost of 300x to 450 x

I need a speed boost of 4-16 times, not 300 x. Because Pentax Auto 110 has only ASA 100 and ASA 400 speed. I shall try to reduce the amount of benzoletriazole.

In a 1952 book "Introduction to Photography" by Tai Huai Ching, published in Sin Chew Weekly magazone in Singapore. listed a speed boost developer described by Philip Priedell in in 1946 November issue of American Photography. Friedell used a two bath developer containing Benzotriazole. He use Dupont sound track film with very low film speed--Weston 8 to take picture with this low speed film and developed in his two bath developer, he got result equivalent to Weston 300 to Weston 460 a amazing speed boost of 300x to 450 x I need to do my own experiment with 16mm Agfa Copex (ASA 16-25) in Pentax Auto 110 camera or EDIXA M16 cameras to see what speed boost I can get. Unlike Swerl, the chemical benzoletriazole is available.

With Rollei A110 camera, loaded with 110 film cassette, never push pass 24. If you force push pass 24, you will jam up Rolllei A110, and you will never be able to pry open it, and ruin the camera

110 film width is the same as 16mm film. Use 16mm film stainless steel development reel to develop 110 b&W film
