Wrong Colour Space Crashing Android Devices

[Trevor.Dennis]

You might have read about the Android glitch last week. If not, the image below has crashed, and in some cases, totally frozen multiple Android devices when it is set as Wallpaper.  This article on the BBC news site has the person who took the photo talking about how he processed it.  He actually used Lightroom [spit] but I'm guessing Lightroom [another spit] has the same output options as Photoshop, and I refuse to visit the Lightroom [third spit and out] forum.  Unfortunately it does not say exactly what colour space was used.  I'd be interested to hear if someone like Dag knows what was going on here.

I thought to look at the image on the photographer's flickr site, but it has no EXIF.  He might have used an export to flickr or export to web type setting, and I think they strip any EXIF.  That's a pity. If I look at the EXIF on one of my flickr images it shows a ton of information.  It might add to the image size, but some of that is going to be interesting to your average photographer geek type person.

My guess is that the Android platform doesn't have a clue what ProPhoto is, and is sent into a death spiral trying to figure out what this strange beast is.

Which is a nice way to illustrate what a disastrous choice of default this is. I've said so on many occasions. Yes, Lightroom sends ProPhoto out to Photoshop by default. And as a result, all those beginners who think color management has something to do with home decoration, pepper the web with ProPhoto images.

It should be obvious: defaults are for beginners. They are not for experienced users who know where dangers lurk. They don't need to be hand-held. Defaults should be safe settings where you can't go wrong. And you can go very wrong with ProPhoto.

Yes, I know a lot of people hate the Lightroom catalog. I sympathize. But it's there for a reason: it allows high-speed, high-volume processing at a scale ACR/Bridge can never even dream of. The capacity is in a whole other league. And to some, that's important enough to endure the slight inconvenience of the added abstraction level.

Hi D Fosse 

I agree with you about ProPhoto being a poor idea for many, is the uploaded image in ProPhoto colourspace?

"It should be obvious: defaults are for beginners. They are not for experienced users who know where dangers lurk. They don't need to be hand-held. Defaults should be safe settings where you can't go wrong. And you can go very wrong with ProPhoto."

yep, right, agree totally

What I see in the EXIF above is

ICCProfile Name - Adobe RGB (1998)

is the Flickr image actually ProPhoto?

thanks

Don't tell Trevor he's in the Color Management forum when he checks back. I think he prefers to avoid color management even more so than Lightroom 😉  Hi, Trevor...there's good news and bad news...
