Since Frans insisted in the thread he helped lock down (before this one does):
How about this
https://www.adobe.com/digitalimag/pdfs/calibrating_digital_darkroom.pdfThe same color scientist, (Karl Lang) I mentioned below who writes:
With the light output levels of current display technology, an ambient light level of 4 lux is an optimal compromise. While a lower light level would provide better results, it’s impractical. You need to be able to walk around your environment. Above 16 lux, the room ambient will have a very significant effect on the dynamic range of the display.\As to the point about lower light levels provide better results (which Frans dismisses in two threads here),
I also pointed out the impracticability to some degree if you can't find a way to turn on the lights when not editing:
The ONLY downside is possibly bumping into something, otherwise, the lack of ambient light means none is striking the display. Which is good!Meanwhile, not a lick of evidence from Frans that a too dark room (undefined but now the bar is 4 Lux) will result in images/prints that are too dark. I'd suspect he could spend his
valuable time trying to prove that but alas, no. Maybe a letter to Enrique Peña Nieto explaining how he will pay for the wall is better time spent than trying to dismiss two color scientists, the ISO and other members here?
