The realized films had 300 to 700 transparent pictures of successive phases of moving figures with black backgrounds. The pictures were hand painted by Reynaud in aniline inks directly on 6 x 6 cm gelatin plates. [ 1 ]
Anti-reflection coating of lenses to reduce transmission losses. May also stand for meter coupling or meter-coupled lenses. Whilst being a generic term, the designation in the latter meaning is mostly used to describe a generation of Minolta SR-mount lenses implementing this feature. MDF or MFD: Minimum Focusing Distance. Minimum distance from ...

Industrially-available sol-gel processes offer up to 84% UV block, [13] while magnetron-sputtered AR/UV-Blocking layers can block up to 92% [14] [15] with no adverse effects on the transmission or absorption of visible light. UV Filtering of the Substrate is possible by adding UV filtering agents during the production of the substrate.
