Hi Chris, hi Marco
Yes, sorry I made a mistake, the correct histogram in RawDigger looks like this:

Understood, makes perfect sense.Guppy wrote: I wanted to keep the flash-burn time short.
An underexposure in RAW format is not tragic.
The noise of a Nikon D810 can be removed very easily at 60:1.
I could have also increased the ISO number.
The D810 falls into the category of cameras that is called "ISO invariant". This means that noise levels are the same regardless of whether you increase the ISO or shoot at low ISO as raw and then levels-shift to make up the difference.
See https://improvephotography.com/34818/iso-invariance/ for discussion.

Hi Rik
(The D810 falls into the category of cameras that is called "ISO invariant")
There is a lot of writing, I measured it myself years ago up to ISO 2000, it is indeed so.
In my comparison, a subsequent brightening was minimally better from ISO 500 on, like higher ISO numbers.
An important difference with Focus Stacking.
If you choose a higher ISO number, there is the possibility of overexposure.
If the pictures are a little too dark, you can adjust the brightness after stacking (Zerene).

Thank you so much Guppy now i now a little bit more you make the stack in raw so you can post processing it more if it is possible too show us the unedit version or a single shot regards marcoGuppy wrote:Hi Chris, hi Marco

Thank you so much for sharing your experience GuppyGuppy wrote:Hi Marco
Here is the unprocessed image.
Kurt
it gives me more details about the process and lighting
i will do some new tests this week and change something about my workflow.
i post the results soon here
ps also the pictures on your website are beautyfull
regards marco
