110 Pocket Film Shooting Tips and Darkroom Manual Reloading Guide

1. The history and physical frame specifications of 110 film

In 1972, Kodak launched the 110-size film cartridge (Pocket Instamatic) for ultimate portability:

1. Micro physical frame size:

• The film frame is 13mm $\times$ 17mm, the area is only about a quarter of the standard 135 full frame (24x36mm), and the crop factor (Crop Factor) is about 2.0x.

2. Single hole positioning and backing paper counting:

• The film width is 16mm, and there is a stamped positioning single perforation under each frame (used to trigger the body shutter lock and counter).
• The back of the film is lined with a complete strip of black backing paper to prevent light leakage, and the frame number can be read directly through the small transparent window on the back of the camera (usually 24 frames are taken in one roll).

3. Integrated double-cylinder plastic cassette (Drop-in Cartridge):

• The film supply shaft and the film take-up shaft are integrated into a plastic frame. To load the film, just throw it directly into the camera compartment, close the back and you can take pictures, and there will be no light leakage when opening the cover midway.

2. Appreciation of top 110 camera models and avoidance of focusing pitfalls

Photos taken by cheap 110 toy cameras (fixed single plastic lens, fixed shutter) are often blurry and blurry; to achieve the ultimate high image quality of 110, you must use a sophisticated SLR body with serious optical design:

1. Pentax Auto 110 / Auto 110 Super – the smallest DSLR system:

• Has a complete set of interchangeable mount-coated lenses (18mm f/2.8 wide-angle, 24mm f/2.8 standard, 50mm f/2.8 portrait, 70mm f/2.8 telephoto, and even macro and zoom).
• Using a true SLR split-image micro-edge focusing system and a stepless electronic shutter through the lens, the resolution is extremely amazing.

2. Minolta 110 Zoom SLR:

• Uses built-in macro zoom lens and aperture priority exposure system.

3. Virtual Focus Avoidance Rule:

• Since there is no heavy metal spring pressure plate inside the 110 film cartridge, the film tends to float slightly back and forth at the exposure window. When shooting, try to shrink the aperture by one stop (such as using a fast shutter in the sun), and use the depth of field to absorb the film flatness error.

3. 16mm film slitting and manual reloading (Reloading) 110 cassette

Original 110 film (such as Lomography 110) on the market is expensive and limited in variety. With cassette cycle filling, top-quality Kodak film reels can be used at a fraction of the cost:

1. Consumables preparation:

• An original 110 plastic cassette shell that has been taken apart after processing;
• One piece of original 110 blackout backing paper;
• 100ft reel of Kodak 50D / 250D / Double-X 16mm cine non-perforated or single perforated film (width is exactly 16mm, perfect fit!);
  -Masking tape and sharp scissors.

2. Hand-rolling method in secret bag:

• Lay the original backing paper flat, and align the 16mm film film about 85cm long with the backing paper according to the number marks "1" to "24" on the backing paper.
• Use a small piece of paper tape to securely stick the film leader to the film supply axis.
• In a total dark bag, stack the film and backing paper tightly and roll them smoothly into the film supply tube.
• Stick the film tail on the take-up axis with tape, and close the upper and lower plastic covers of the 110 cassette.
• External sealing: Use black light-shielding electrical tape (3M insulating tape) to seal the upper and lower joints of the cassette tightly for 2 turns to completely prevent light leakage from the gaps in the cassette.

4. Manufacturing of washing coupons and scanning fixtures

1. Display reel modification:

• Regular stainless steel or AP plastic spool widths designed for 135/120. Special flush spools for 110/16mm can be purchased, or a plastic retaining washer can be inserted into the standard spool groove to lock the spool width to 16mm.

2. Film digital scanning fixture:

• Dedicated film scanners usually do not have 110 format film holders. Use 3D printing to create a special 110 frame with anti-Newton ring glass, or hand-carve a 13x17mm window on an Epson scanner holder with black cardboard for high-DPI remakes to fully squeeze out the fine grain of 16mm.
