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?

Have you tried restarted Chrome since you changed the display profile?

I can't speak for OP but say this does effect 1% of users today, what percentage does it effect in 6 months, or a year? Not bad to be proactive. And regarding android compression issues, although resources are always finite, I imagine in this case the android team is fairly separate, so they may very well be working on that compression issue while iOS is pushing forward into new terrain.

> I imagine in this case the android team is fairly separate This is likely it, right here. So many people forget that larger companies have different teams working on different things. I bet a lot of their "iOS people" that are working on this project have no clue how the Android app works, and Instagram likely has a separate team working on the compression issues.

"Working on" since 2012?

Are 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.

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.

Pillow doesn't do anything with gamma by default, nor does it require that color management be compiled in.

(I'm a maintainer of pillow)

Here if anyone has questions on the implementation or such.

"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…

I was never under this impression. I was always under the impression the filters are just created by a designer playing around with various effects until it looked nice.

I don't use IG, so I wasn't aware of that problem or how long it had been around. That said, the general sentiment stands: one of their teams working on one thing doesn't show that they don't have another team working on something unrelated.

Chrome should be able to display it fine. The dl=1 param on the Dropbox URL means the request is served with a response header indicating it's a download. Change the link to dl=0 and it won't force the download.

link for the lazy: https://www.dropbox.com/s/tgarynpj65ouafd/insta-logo.png?dl=... By the way, anyone who can display it (all my nice monitors aren't with me at the moment) can you see it on this imgur link? http://i.imgur.com/qCna54M.png

I can see the logo on the imgur link on my TouchBar MBP

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 circumstances, where the cameras create images in a different color space and higher bit depth that can't be perceived at all with any technology or the human eye.

In the "How I Built This" podcast for Instagram, Kevin Systrom specifically says the filters were created to take the relatively low-quality photos early smartphone cameras were capable of and making them look like photographer-quality photos. Filters were about taking average photos and making them "pop" but not necessarily by virtue of having deep domain knowledge of color.

So... 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 though, so if this is what you're talking about: awesome, please update your article so people can find out more about this color model and the rest of the world can catch up!
