When on Android? I also opened a bug on Android Bugtracker: https://code.google.com/p/android/issues/detail?id=225281 and it is marked as a small issue. On Android we are lacking color management and are only restricted to sRGB. Original Wide Gamut and P3 images look dull on Android devices. I also want good wide P3 colors and color management without buying an iPhone.

"When we started this project, none of us at IG were deep experts in color." This is pretty astonishing to me. I always thought applying smartly designed color filters to pictures was basically Instagram's entire value proposition. In particular, I would have thought that designing filters to emulate the look and feel of various old films would have taken some fairly involved imaging knowledge. How did Instagram get…
Because it isn't complicated or novel to make compressed 8-bit jpegs have color filters. There are tools for the job and they've been around for a long time. Working in a different color space than standard requires a little bit of familiarity and finesse that modifying 8-bit jpegs for consumption on the internet did not require. Many photographers and printers are familiar with this dilemma in a variety of circumsta…
I'm sure the comment you're replying to wasn't thinking of the algorithm that applies a filter to a jpeg, but the process by which that filter is created in the first place. The assumption being that there's some sort of theory to colour that allows you to systematically improve the aesthetic qualities of images.
As an analogy, think of the value music theory (i. e. https://en.wikipedia.org/wiki/Scale_(music)#Harmonic_content) for composition.

I this why iPhone photos of red roses, or other vibrant roses look poor? I love the idea of a photo room is it hand painted?
Yes they look poor if you watch them on not color managed software environments (should not happen on Apple devices). See here a sample image https://code.google.com/p/android/issues/detail?id=225281
Re: Bringing Wide Color to Instagram
#94I'm not sure if this is different in the iPhone 7, but the 6S is pretty terrible at color representation in photos, specifically when dealing with neon lights. The iPhone tends to overexpose the neon light to make up for the surrounding being darker, so to get a 'decent' shot, I have to down the exposure by about 2/3 on the 'brightness' in the normal Camera app. But in general, it has a hard time showing as good of c…
That's more a problem of the camera and ISP and not color management and display.

#95If 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?
Chrome does something strange with colors on macOS. Colors always render visibly different than Safari.
That being said, the logo is visible in Chrome for (using a Dell display).

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.
Oh no way! That's awesome, apologies for not knowing this and thanks!
They mentioned this in the post but it was fairly well hidden, can't blame you for missing it.

Good to know--I didn't run it through my Pixel. Some devices will do a relative projection from Display P3 to sRGB, which means that it will look "relatively" like it would in Display P3 but projected onto the sRGB color space. Edited to add: and some other ones are doing something even less fancy, which is just to ignore the color profile entirely and just assume sRGB and display it incorrectly, taking for example w…
Since you brought up your Pixel: what is the point of adding something 1% of your customers maybe can see instead fixing that horrible horrible compression that makes uploads from android (80% world wide market share) look like crap? (Not an android user, I just want to figure out how a company of your size prioritises between bugs and features.)
> (80% world wide market share)
Not of instagram user. Not of app users.
Re: Bringing Wide Color to Instagram
#98So... what is "wide color"? Are we talking https://en.wikipedia.org/wiki/Wide-gamut_RGB_color_space or something else that has no documentation anywhere on the internet? Not trolling, I care an incredible amount about color spaces, and had expected support for something like the UHDTV Rec.2020 color space with D65 (cool/blue white), not an obscure Adobe standard with D50 (warm/yellow white). It's wider than Rec.2020…
It was in the fourth paragraph: > The color space that Apple chose for its devices going forward is Display P3. https://en.wikipedia.org/wiki/DCI-P3
How extremely disappointing.
Re: Bringing Wide Color to Instagram
#99Here if anyone has questions on the implementation or such.
It's great you listen. So I'll try.
1. Scaling down in linear colorspace is essential. One example is [1], where [2] is sRGB and [3] is linear. There are some canary images too [4].
2. Plain bicubic filtering is not good anymore. EWA (Elliptical Weighted Averaging) filtering by Nicolas Robidoux produces much better results [5].
3. Using default JPEG quantization tables at quality 75 is not good anymore. That's what people referring as horrible compression. MozJPEG [6] is a much better alternative. With edge detection and quality assessment, it's even better.
4. You have to realize that 8-bit wide-gamut photographs will show noticeable banding on sRGB devices. Here's my attempt [7] to reveal the issue using sRGB as a wider gamut colorspace.

Re: Bringing Wide Color to Instagram
#100Are browsers generally color-correct? I was going through the Webkit wide color examples and was getting different visual results on different browsers[1]: https://webkit.org/blog-files/color-gamut/ [1]: Compared Safari, Firefox and Chrome on a 2016 MacBook Pro w/ Touchbar running macOS 10.12.
Browsers are all over the place, unfortunately. It's part of why sRGB because the only reasonable color profile for Web use. I think we'll see wide color become common in apps before the Web.
All over the place in what way? Support for different color profiles? Actually handling color spaces at all? The fact that there's no consistency when it comes to untagged images? The mess which is plugins? The ability to specific CSS colors in a specific color space?
