DR settings modify displayed ISO. When using DR400 @ ISO 1600, the camera is actually shooting at ISO 400 and pushing 2 stops (you are not shooting à 1600 and pushing). In modern cameras, pushing shadows and using higher ISO is essentially the same, resulting in the same amount of noise. So yes, ISO 1600 @ DR 100 = ISO 1600 @ DR 400 in terms of noise. Actually, the ISO 1600 @ DR 400 will have slightly less noise in the higher tones were you are not lifting the exposure.

Hi Romain! Thank you very much for our feedback. Kind regards!

I like to use DR400 and Highlights to -2. Overexpose by +1 and get very soft colors. 😊

Thank you so much for the explanation. I hope on more videos explaining technical settings in the Fuji cameras.

Hi Robert! Thank you very much. I'll certainly make more videos on technical aspects of the Fuji cameras. Kind regards!

Always enjoyable content. And the only snow I ever see these days...

Thank you so much! I'm always flattered to have you as a viewer. And yes, lots of snow here.

helpful. thank you for the efort and the sharing. thank you for the thoughtful discussion. i now have a better understanding of the DR function. do you have thoughts on compressed raw vs uncompressed raw? i am using the X-T1 and the X-T2. thumbs up.

Hi! Thank you very much for watching and thank you for the idea of talking about compressed and uncompressed raw files. I should make a separate video on that. The uncompressed raw files offer no loss in image data, so they offer higher image quality (fine details and color information). But these files are larger and slower to transfer. I'd say that if the image quality is of the highest importance (and it usually is when a photographer decides to use raw files) I'd recommend to go with the uncompressed files (unless storage space is limiting). Kind regards!

DR setting effects the raw files… also thanks for the great video it was very informative 🙏

Hi Jason! Thank you for your feedback. The DR settings do not directly influence the raw files. They are used by the on-board JPEG conversion software to convert the raw version into a JPEG file. That said, there can be indirect implications. For example when using high DR you may choose different metering settings and these can influence raw files. Some cameras may incorporate certain default settings into raw file and some of them can be indirectly influenced by your DR settings. So the DR either does not affect your raw files or sometimes may have subtle and indirect effects on it. Kind regards!

@@JasonLawrenceNoel Hi Jason! What happens when you increase the dynamic range is that the camera may want to underexpose (depending on the model) so that it could later rescue the highlights (and lift the shadows back to "normal") when producing the JPEG. In that case the shutter speed is shortened and the original file will appear darker. So the DR settings can sometimes indirectly influence the raw file but not in the sense of increasing dynamic range. I hope this makes sense. Another way of proving that the dynamic range of the raw file is not influenced directly by DR settings is this: Take a raw photo with any DR setting. Now have the camera turn your raw file into JPEG. (You can do this in your Fuji menu). You can again choose DR 100%, 200% or 400% for your JPEG (and this is not influenced by what your DR settings were when you took the photo) and you will get a JPEG with the desired dynamic range. So the raw file will always have all the info to reproduce any of the DR settings for the JPEG. Now some people say that the different DR settings make their raw file look different when it is first opened. This is because the meta data of the photo may have certain flags saved that tell the photo manipulation program what initial settings to apply when it first shows you the raw image. So the raw file is not modified by the settings, instead the settings determine how to display the raw file. Some photo manipulation programs may honor these flags or they may not, this varies. This may sound confusing at first. I hope this made some sense. Kind regards!

hi there, judging from what I have learnt and your images shown here I think the reason you dont see much more noise at higher iso is not that there isn't an increase in noise but that your camera is applying Heavyer noise reduction, I think that is visible in you example 7 min in. Turn off noise reduction and try. Another thing, I heard some other youtuber say that in high dr mode, the reason you need to increase your iso setting is that it increases the iso to that level yes, but ONLY on the pixels on the sensor that receive less light, so that you keep details in the shadows at the same time as having a shorter shutter time to keep more detail in the highlights, if this is correct you would see no iso noise in the brighter parts of the image. I wonder if this is true.

Hi Hærleif Langås! Thank you very much for your comments. The noise reduction can, indeed, change the apparent noise. Noise reduction was set to 0 in my experiments. The comments you made about increasing ISO for the pixels that receive less light I cannot comment because I have not investigated this or done experiments. I have some doubts that this is how the higher ISO works but I cannot say much until I have taken the time to investigate. Kind regards!

Your test is a good thing, maybe it's not the center of question... Some years ago fuji took Nikon d100 and replaced the sensor with its special one made of two defferent size receptors... It had advantage in hi-lights, not in shadows, or rather: math description of tones is a log curve so in its nature has less data for shadows, if you have bigger receptors you catch more light, so you can lower the exposition and save the before clipped portion of hi-lights, it's not having more data to describe shadows, it is extending the dynamic range towards lights.... Time passed and this technology was replaced by better sensors but Fuji applies a similar behaviour: by setting DR 400 the camera acts like a double exposition, one for normal base and the second for hi-lights, than mixes in one raw... Doing this is not possibile on native iso base and for this reason you need to increase iso to 800 (now 640). In short: dr is for situations of hi-light clipping and, imo, Nikon does a better work with D-lighting for shadows. I suspect tha iso 800 is only a visual setting on dials because of sensor invariace...

Hi Mattetifaitutorial! Thank you very much for your informative and interesting post. I think one of the main conclusions is that for a good dynamic range raw files are better than the camera's DR functions. Kind regards!

If highlight gets blown out, just use a Nikon D5000 and problem is solved .
