Bmpcc4k Dynamic Range Part 1 Relationship Between Iso And Raw Low Hi folks, tony dae here.i was asked to make a video discussing the dynamic range and how shooting raw and changing the iso affects the dynamic range. this vi. If you don't use the film setting, it will apply the video lut to it. that can be overwritten in post however. it just gives you a starting point. in braw, you don't lose dynamic range. the only thing that you have to be concerned with is which of the two iso ranges to use, as that will determine which amplifier circuit the sensor uses.
Bmpcc 4k Dynamic Range Allocation Blackmagic Design Cinematography Due to the extra gain of it's amplifier circuit, the higher iso range in a bm dual iso camera has less dynamic range. "using the full sensor readout at the maximum resolution of 6k (6144×3456) with braw 3:1 constant bitrate settings, (iso 400)a dynamic range of 11.8 stops at a signal to noise ratio of 2 is calculated (12.9 stops for snr = 1). The result: 11.6 stops of dynamic range for a signal to noise ratio of 2 (12.7 stops for a signal to noise ratio of 1) at iso 400 (10.5 and 11.8 stops for iso3200), in prores 4k dci 25p. interestingly, when we tested the same dci 4k 25p raw (1:1) we found that the dynamic range reading was lower (by about a half stop). The camera is a dual, iso invariant sensor, meaning you have basically, two native isos, 400 and 3200. iso 400 offers a little more dynamic range, but 1250 is where the high circuit cuts in, giving you better shadow details but less dynamic range in the highlights. if you are shooting raw, only 400 and 1250 actually change the sensor exposure. Re: this says native iso is bs you will lose 1.1 stops of dr by going to the higher iso range on the bmpcc 4k. "the result: 11.6 stops of dynamic range for a signal to noise ratio of 2 (12.7 stops for a signal to noise ratio of 1) at iso 400 (10.5 and 11.8 stops for iso3200), in prores 4k dci 25p." if you shoot in prores, it bakes in the iso.

The blackmagic pocket cinema camera 4k is know for its dual native iso. but what do the noise levels look like at each iso? and how does the relationship bet. In this episode, we discuss the confusing topic of dual native iso and the effect it has on the dynamic range in the bmpcc4k. this is a crucial part of the c.
