I did not know that Instagram was using OpenGL for processing. That's pretty neat, given the capabilities of OpenGL. I'm looking forward to seeing more filters with more lifelike Polaroid effects.

But before that, could they not convert images to horribly encoded JPEGs? I get it, bandwidth and costs, but it's an image service that still drowns in its own... when it gets an image with strong reds and blues.

We started using OpenGL in 2011. Our CPU-based image filters used to take 4+ seconds with pixel-by-pixel manipulation, and now can render 30+ times per second.

If you have some sample images where the current image pipeline is going wrong let me know and we can look into improving.

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

Yes, was a bit confused when I opened the image on my ancient work computer (Windows, old Dell monitor) and could see the logo clearly. Interestingly, Chrome refused to display the image despite it nominally being a PNG, and I had to open it via an external program. Dragging the window to my second monitor (different model) causes the logo to vanish (though I do feel like I see it for a split second on the second monitor... optical illusion?).
