I have an HW40ES which has been calibrated by a professional.
The before / after difference was clear.
And the advice brought very formative.
I am not a professional myself, I will just qualify as passionate.
For the PPM, I find that the color temperature is too warm.
But, you know, I personally find it is a great pico.
Its portability and its quality are there.
But knowing full well that a software improvement exists and that it should arrive soon, I am impatient to be able to further improve my “portable” cinematographic experience
