Lomography Orca B&W 110 100
Orca is one of the reasons Pentax Auto 110 and Minolta 110 Zoom cameras still get loaded in 2026. Lomography began producing 110 cartridge film in 2012 with Orca as the black-and-white entry, an ISO 100 panchromatic stock that arrived alongside Color Tiger and the other 110 stocks that revived a format Kodak and Fuji had both dropped by 2009. The 110 frame is 13mm by 17mm, less than half the surface area of a 35mm frame, so any 110 film starts with a resolution disadvantage that no emulsion can fully cancel.
Lomography does not name the OEM for Orca. Speculation in the format community rotates between Foma Bohemia and InovisCoat in Germany, with current boxes marked Made in the Czech Republic after a sourcing change away from the earlier Made in Germany cartridges, with current batches reading closer to Fomapan 100 in grain structure and tonal scale than to anything from Ilford or Kodak. The match is not perfect. Orca's contrast runs slightly higher than straight Fomapan 100 and the highlights compress sooner, suggesting either a different developer-incorporated layer or simply tighter slitting tolerances for the small format.
At box speed in good daylight the film gives you what 110 can give, which is a print or scan that looks fine at postcard size and shows its grain at anything larger. Cubic-grain old-school character. Decent shadow detail. A curve that resembles a budget Czech B&W more than the smoother modern Ilford stocks. Rate at 80 if you want extra shadow latitude, though most 110 cameras have fixed-aperture or fixed-shutter behavior that limits how much you can compensate.
Processing is standard B&W at any lab that still handles the format. D-76 at 1:1 or ID-11 work well. Most labs will scan from 110 but will not print directly because enlarger carriers for the format are scarce. Cartridges come 24 exposures each in three-cart packs.
Reciprocity exponent is 1.31. Zone Light Meter applies the correction past one second, putting a 30-second meter reading at about 90 seconds at the negative. With most 110 cameras locked at shutter speeds in the 1/100 range and limited bulb support, the threshold rarely matters in normal shooting.
How the app handles this stock
- Box speed: ISO 100. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: Above one second the app raises metered time to the power of 1.31.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. B&W negative decay rates are baked in.
