The 105C with coarse thread Tiffen #12 Yellow Filter 105C Coarse Threadfrom Tiffen #12 Yellow Filter 105C Coarse Threadis a filter designed to increase contrast and tonal separation for black and white photography. The filter absorbs blue colors, rendering blues darker. Haze is minimized for aerial photography and excessive blue is removed for astrophotography. The #12 Yellow Filter is recommended as a basic filter for use with Kodak's Aero Ektachrome Infrared Film. The filter has a filter factor of 2, so you must increase by 1 full stop to your exposure to compensate.

Tiffen filters are not dyed, but are manufactured by using ColorCore technology. This process laminates the filter material between two pieces of optical glass and grinds down and polishes the glass. The glass is then mounted to the metal ring, which after that can be screwed onto the lens for the desired effect.

Q: 6. I use P-Touch labels to mark (and match) sets of AA batteries. Will this holder work with AA's that have a label wrapped around their circumference, or will it be too tight to fit?

A: I’ve labeled mine with a brother labeler (unsure which model) and its workable if you’re really careful when getting them in and out every time... but it’s a hassle. It is very tight and ended up tearing the paper labels and messing up the thicker plastic ones after a few normal uses, so I quit using the labeler.
