Hello Folks!
I spent the last two hours looking into something that has caught my interest for quite a while and I was not able to figure it out on my own. So, if there are any ressources I have missed that answer my question, kindly point me to them and I will delete this thread
The topic is ISO in RAW recordings on the URSA Mini Pro 4.6K. I learned that the camera is ISO invariant, meaning, to my understanding, that the sensor-data is recorded to RAW at native ISO of 800 and the ISO-value is just meta-data.
Somewhere along the articles and posts I read when learning how to use the camera, I read that the ISO is not only sensor amplification, but also influences the dynamic range in the dark and bright areas. Someone said that this even goes so far that using ISO 1600 in daylight is not unrealistic because it gives more dynamic range in the high tones and therefore can prevent highlights, which are obviously there in daylight, from losing information. This is an information I could not validate from any official resource, but seen from a technical point of view it definitely makes sense to me.
IF it is like this and the ISO value influences the stops of dynamic range above and below mid-grey, I am curious if this also applies to RAW recordings and, if yes, if it is also applied by the RAW-processing software later or if this is not "invariant", meaning it directly applies to the sensor and the recorded data.
The topic is a bit difficult to describe or phrase, if you have not completely understood the process (and are not fluent in English ). Just let me know if you have questions about what I mean.
Thanks in advance and best greetings!
