Awesome, would be great to see in-app support for 2x optical zoom on the iPhone 7+ next

We built this in already! We don't have a "1x" or "2x" indicator, but the dual lens camera is fully used in Instagram now and will do the smart transition between 1x>2x optical and 2x+ digital zoom.

Note that the red test image is only valid for iOS devices, since in Android you can see the Instagram logo even though it doesn't support wide color

Can't see the logo on OSX Sierra on my 2014 MacBook Pro Retina 13in.

I couldn't either on my MBP late 2013 until I changed the Display Profile to "Display P3". There are other profiles that will show the logo, too, like "Adobe RGB (1998)"

I don't think that computer has a wide-color display. The 2016 MBP should (at least, the one with the touchbar, not sure about the one without), and the retina iMac supports it as well.

If you change your display profile like this you're going to have incorrect color rendering, so don't forget to change it back after you've had your fun looking at the (inaccurately-rendered) image.

Here if anyone has questions on the implementation or such.

Bit of a jump in topic, but I'm kind of curious: I don't use instagram myself, bugt I'm sure it resizes images for online viewing, saving bandwidth ans such. Does it do so with correct gamma[0]? Since that's a thing many image-related applications get wrong. [0] http://blog.johnnovak.net/2016/09/21/what-every-coder-should...

If it's using Pillow for the resizing, probably not. I've not looked at Pillow specifically, but PIL certainly wasn't very good.

Do you test with Adobe RGB (which many prosumer cameras can output) or only P3 (which AFAIK only Apple devices output)?

If you have a Macbook and can't see the logo on the canary image, try changing the color profile for your display. On my mid-2014 rMBP, the default color profile was "Color LCD", but I could change it to "Display P3" and see the logo. To make the change: System Preferences -> Displays -> Color

Thanks for the hint. On my 2015 Retina MBP, when opening the IG image in Preview, I see the IG logo. However, when dragging the image into Chrome, I do not see it.

How do I get Chrome to do proper rendering?

Oh no way! That's awesome, apologies for not knowing this and thanks!

Just P3, though the wider gamut available in our graphics operations should benefit photos brought in using Adobe RGB too since iOS is fully color managed.
