In this video we are going to look at BRAW 3:1 footage out Sigma FP, recorded with a 12G BM video assist. The clips were imported into DaVinci Resolve Studio 17.
The aim of this video is to determine how you should expose your subject best for each ISO in order to get a “good looking” image. I've defined this as an image where the subject isn't clipped, there aren't significant noise levels and there isn't a considerable color shift.
I’ve recorded clips in the ISO range 100 - 25,600, in 1 f-stop increments. For each ISO I’ve exposed the image in the range: + 6-6.5 EV (meaning 6-6.5 f-stops over exposed) to -2.5 EV (meaning 2.5 f-stops underexposed).
For each ISO you will see clips that are decoded using Camera Metadata and BM Film (and a false colors representation of each image), a side by side comparison of the two, exposure compensated clips, maximum shadow recovery and what the noise levels of very under exposed images look like.
If you want to know more about the setting of the shots, how the exposure was measured and what the data analysis protocol was for each measured parameter, check out "How to correctly expose Sigma FP RAWS Ep. 1 Protocol": • How to Correctly Expos...
