Fujifilm X-T3 Dynamic Range (DR) optimisation explained and tested
This video is to accompany the analysis of the Fujfilm DR test on ExposureWorks:

The results do not only apply to the Fujifilm X-T3 but to every Fujifilm camera that has Dynamic Range (DR) settings.

Description:
The test was prompted by a discussion in one of the several Fujifilm X-T3 groups. Someone asked what “DR400” was, someone explained and yet someone else claimed that this setting “worked” on RAW files as well as JPEGs.
This claim is wrong. The Dynamic Range optimisation setting only affects JPEGs in order to ‘pull’ highlights and ‘lift’ shadows when photographing high-contrast scenes with a very wide initial dynamic range.
In order to show what does setting does (and does not do), I shot a series of test images with a Fujifilm X-T3. I shot images at ISO 400, 800 and 1600. The ISO 400 images was mildly underexposed (EV -0.7), at ISO 800 it was mildly overexposed (EV +0.3) and at ISO 1600 a bit more overexposed (EV +1.3).
The test images clearly show that:
1. the DR setting compresses the highlights and lift the shadows in JPEG images.
2. the DR setting does not affect the identical RAW images.
3. this is not universally true in the sense that some image editing software applies the DR flag of the JPEG to the RAW during processing. Adobe Lightroom does not apply it. Capture One does.
