Yeah you are right, I have a huge window in the studio that I haven´t got around to block more than with ordinary blinds.
I have a balanced high cri led panel that is dimmed so when I measure it it´s something like 60 lux in the room.
That in winter time in sweden when it´s dark out. Now it´s bright out most of the day and some days the sun shines right at the window.
I´f i put my mpb or iphone on it´s brightest setting it feels way brighter than 100cd/m2, and i guess thats how most people run their screens. I was thinking that some one had calculated some magic median setting that would reflect most peoples screens, but thinking more about it i guess it doesn't work that way, If i edit an image in a controlled environment so it looks good, it should look more or less allwright in under different conditions/screens right? so instead of brightening the screen i should get some big black out curtains. I get that it´s all in the relationship between screen and ambient. But it´s still confusing thinking about that we run our screens pretty dark and the people viewing the images probably (mostly) run theirs way brighter, and our way of dealing with that is to make our rooms dark. Then it´s the calibrators with ambient measuring that it´s supposed to compensate, but to me that feels a bit like i don´t trust them (without ever trying to use that function).
