CML-CMIR Movie Lens Evaluations January 2016

These evaluations were shot with the help of CMIR at UWE's media centre.

The object was to show the issues caused by lens flare and veiling glare, both issues that have had a serious effect on recent images that Geoff Boyle has shot!

Shot with C500's in 2K 12 bit 444 recorded on Odyssey 7's in ProRes 444XQ

Assembled using Resolve in YRGB with a standard Canon LUT. An HD frame was cut out of the shot image. I.E. the 2048 * 1080 frame had the edges chopped off to give us 1920 * 1080. In the case of the anamorphice we again chopped off the sides of frame to give us a 1920 * 1080 image, we added some repositioning in these shots to make sure that the area of interest was centered.

Exposure set and matched with exposure meter in incident mode.

No other adjustments were made. Any colour or exposure varaitions are due to the lenses.

Lit with KinoFlo LED softlights set to 5600K.

No matte boxes or lens hoods of any kind, moves matched with RevolveR MOCo head.

Lenses were, Angeniuex Optimo 15 - 40 at 18 & 32, ARRI Alura 15.5 - 45 at 18 & 32, Fuji Cabrio 19-90 at 19, 32 & 75'ish, Canon 17-120 at 18, 32 & 75'ish, Canon 14.5 - 60 at 18 & 32, Vantage Hawk 2* & 1.3*, Vintage 74, Canon Cine Primes, Cooke TLS S3, Mini S4, S4, 5i & Anamorphic , Illumina Coated & Uncoated, Leica Summilux & Summicron, Schneider Xenar, Xenon , Zeiss Master, Ultra, CP2, Otus & Milvus

There are large variations at the start of the light location shots due to direct sunlight in some case.

In all cases the second half of the shot is only hit by diffused light and is directly comparable.

Exposure was set in all cases by using incident light reading at the subjects face, any variations in brightness are due to flare. Gain was used in some cases, pushing the ISO to 1600, to keep the aperture a constant T2.8.
