00:00-01:09 Intro
01:10-01:46 Sigma FP's monitoring issue
01:47-03:13 How "standard" false colors work
03:14-04:25 Sigma FP's false color
04:26-05:01 Issues I heard about with FP's false color
05:02-07:42 FP false color test footage ISO 100 - ISO 6400
05:03-05:47 ISO 100
05:48-06:07 ISO 200
06:08-06:29 ISO 400
06:30-06:59 ISO 800
07:00-07:12 ISO 1600
07:13-07:27 ISO 3200
07:28-07:41 ISO 6400
07:44-08:04 Conclusion A: False colors shows accurate clipping
08:05-10:47 Conclusion B: False colors uses RAW image
10:48-12:01 Conclusion C: False colors shows crushed shadows too soon
12:02-13:03 Well exposed footage
This video is centered around tests with Sigma FP’s „standard” false color – the one that came in firmware update 4.0 in 2022, not EL zone, which was added in firmware update 5.0 in February 2023.
Here’s what you can find in the clip:
- An introduction in false colors and how they work generally
- An explanation of Sigma FP’s false colors scale
- Footage with the “normal” image displayed on the monitor side by side with the false colors image for ISO 100 – 6400 in steps of 1-stop. These have exposure values starting from 1 f-stop higher than the clipping point and down to a couple of f-stops lower than that.
- Some examples of CDNG footage in REC709 and BMFilm side by side with the corresponding false colors images
- Some examples of footage that was exposed properly for skin tone – CDNG and false colors side by side.
Some users commented on our previous videos about FP’s false color not showing the clipping point accurately. I also found a reddit thread about this. This is why I wanted to investigate this matter. To be noted is that I didn’t get to look at false colors prior to the 5.0 update, so I don’t know if the feature worked well from the very beginning or they fixed it with firmware 5.0.
