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. 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.
Bmpcc 4k Dynamic Range Allocation Blackmagic Design Cinematography 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. 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 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. Denny smith wrote: the camera is a dual, iso invariant sensor, meaning you have basically, two native isos, 400 and 1250. 400 offers a little more dynamic range, 1250 better shadow details but less dynamic range. if you are shooting raw, only 400 and 1250 actually change the sensor exposure.

The alexa has 1.5 stops more dr than the bmpcc4k and its range is better balanced. it's really not fair to compare a nearly $80,000 camera to a $1300 camera. arri doesn't have to think about it's chip set, they use the best period and whatever it costs to make, plus profit, is what they charge the customers. Re: higher iso settings (>6400) shooting raw on bmpcc4k. denny smith wrote: from what i understand, any iso above 6400 is actual analog gain being applied on top the high range of the sensor, so i gets baked in, and is no longer variable iso metadata, like it is for the low high range setting. how was the video noise at this level.
