Besides the cherry-picked colors of green from the top of the screen, the author assumes turning up the screen brightness reduces contrast in the same way that applying a brightness filter in photoshop does. That’s obviously not true - a given colorspace has less dynamic range if you make everything brighter in photoshop, but turning up your screen backlight brightness makes everything brighter by a constant factor, which doesn’t change the dynamic range.
- sliken 4y agoAssuming a perfect screen, yes. But at some point the brightest pixels on the screen will get no brighter, but all the other pixels will. So the dynamic range decreases. Similar happens when dim enough.
- machinawhite 4y agoI just checked and there's a significant difference between full brightness and a little less than full brightness so I'll just assume the screens Apple is using are pretty good at that
- aoeusnth1 4y agoDoes a blank white screen not get brighter on your phone when you turn up the brightness?
- sliken 4y agoI have a pixel 6 pro, and it does look like I can't wash out the brightest. However on a grey scale test image I can lose the bottom 1/3rd of the range by going too dark. Maybe the brightness cap is to save battery.
