Appreciate the feedback and notes here- I would love to revisit the methodology and use a separate physical brightness meter to normalize for that. To my best memory I made sure both devices were at max stock brightness for each photo.
Not to my knowledge, I think Samsung was one of their manufacturers for a while, but they do have patents on nano texture which differs somewhat apparently from traditional matte screens. I'd love to understand more of the differences and more about their manufacturing process though.
You’re not the only one to mention that in this thread. I’ve had a nanotextured MacBook as a daily driver for about six months, and I have no clue what you are talking about. Maybe the issue is iPad only?
Rainbow isn't really the right term. It's more of a sparkling effect. Apple actually uses the term "sparkle" for this characteristic in their patent for the display treatment (see para 0073). They also mention that different diffractive layers can be used to minimize the effect, so it is possible that the issue is worse on some devices than others.
Well whatever it is, my MBP screen looks perfectly fine. It's like a matte display, but not with the colors all washed out like the matte displays of yore. No visible artifacts of any kind that I can see.
I personally haven't noticed that. I am also primarily coding & writing rather than image editing or such so am less sensitive to things like that fwiw.
Curious if you were using AirPods or other Bluetooth headphones for this?
If so, there should be "keep microphone on" or similar setting in the config that may help with this, alternatively, I set my microphone to my MacBook mic so that my headphones aren't involved at all and there is much less latency on activation
Relatedly, has anyone seen tooling or approaches to calculate shadows behind particular hills and mountains, depending on the season and time of day? The sunset calculation for Boulder Colorado is quite inaccurate as we are in the foothills with mountains to the west. I've been pondering how to calculate this precisely.
Given the mountains, the sun would appear to set when it descends below some altitude angle. Given the equation in the wikipedia article you'd then just solve for the hour angle. (You'd then have to use your latitude to convert the local solar time to Mountain Standard Time.)
Perhaps a rough look-up table for (say) each 10 degrees of azimuth around the observing point that gives the altitude to solve for? Finally a couple of iterations to find what azimuth the Sun will be nearer the actual setting time, perhaps taking the 'flat horizon' setting time as a starting value?
