Does the workflow for processing DNG files result in an unavoidable loss of dynamic range?
For example, when opening up a dng sequence into after effects, at first I am presented with the CameraRaw dialogue. Setting all sliders to their defaults, I had hoped that the raw floating point pixel data would come through to after effects. it would seem that I am mistaken.
In the below examples, I have brought in the dng sequence, ensuring all CameraRaw settings (except white balance) are set to leave the image in tact. Once inside after effects, I can see that the dng sequence is in "trillions of colors" and I have set my project up in 32-bit color.
But what I do notice is that the Dynamic range is compressed. By stopping down the exposure, you will notice that the highlights are clipping.
But if I go back into the CameraRaw dialogue, and stop down the exposure by the same amount- it behaves as expected, I see that the floating point pixel values are behaving as expected and a nice superbright hotspot remains.
Can anyone give me some ideas about how to preserve the dynamic range when working with dng sequences? or give me some further insight into what's going on?
Edit. Or is what i am seeing above, simply a difference in how the exposure treats gamma between the cameraraw dialogue and after effects itself- and in fact, the dynamic range itself is retained once inside after effects.
