BMPC-4K: Shooting indoors, in lowlight, with a long lens.
I shot footage for a documentary this week using my “Blackmagic Production Camera 4K” camera, including using a rented Canon 70-200mm f2.8L IS II zoom lens. The photo below shows the two positions where my BMPC-4K was located this past Sunday during two morning religious services, one after the other. Note the multiple sources of dim, very different color-temperature ambient light: Daylight through windows, and incandescent & florescent ceiling lights.
Below are frames grabbed from the “ProRes 422” 1080p29.97 video. Shot @ f2.8, ISO 800, with shutter angle at 270 to increase exposure. “Video” (Rec.709) mode per client request. The medium shot is from the position in the back pews @ 200mm. The close-up is from the front row @ 200mm. The lens was fitted with a 77mm Hoya IR-UV cut filter. Camera is running firmware 1.9.7. These frames have basic color correction applied in post, but more and better correction is possible working with the 10-bit 4:2:2 “ProRes 422” files.
Below are some cutaway b-roll shots of the congregation (same settings as above):
During a breakout session between services, the featured speakers were seated with their backs against a bright window. Lighting is a mix of ambient daylight and ceiling incandescents. The wide shot is @ 70mm, and the close-up is @ 200mm. F2.8, ISO 800, shutter angle 180, “Video” (Rec.709) mode.
Below are frames from interviews I shot yesterday using the lens set at about 100mm, f2.8, ISO 800, shutter angle 180, “Video” mode, WB 3600K, hot tungsten lights (650w key, 250w backlight), Hoya IR-UV cut filter.
I also shot a lecture in a classroom setting using my Sigma 18-35mm f1.8 lens, again under mixed lighting. Here’s a cutaway shot of some of the students @ f1.8 ISO800 4800K:
