And while I think the site strikes the balance decently at the moment, Pro is too expensive for ads to get more intrusive (for the Pro user and for others looking at his/her photos).

But as I hope was clear, I'm a big supporter and would love to see the platform continue to thrive. If you're ever looking to bounce thoughts off a user, or anything else, I'm happy to help!

Color management is a largely solved problem, so I've historically used ProPhoto RGB, but this has the real downside of introducing banding due to the stretching of such a wide color palette across so few steps (256 per channel). It's so wide that many of those few steps (a) can't be rendered on modern monitors, and (b) are not even visible to humans (i.e., are imaginary). Colors represented by those steps are wasted.

Adobe RGB expands upon sRGB primarily in the cyan-green direction but leaves out vibrant reds and yellows. Lots of displays cover 100% of aRGB (but less of P3).

Display P3 expands upon sRGB primarily in the red and yellow direction but leaves out vibrant cyans and greens. Lots of displays, most notably modern smartphones, cover 100% of P3 (but less of aRGB).

Both of them help minimize wasted bits, but neither of them covers all sets of realistic vibrant colors. I worked with Gemini and Copilot to create a color profile for the minimal triangle that covers the farthest reaches of both color spaces.

Specifically, I asked Gemini to do the complex math to establish the correct x,y primaries to ensure the full convex hulls of both gamuts is within the new gamut while keeping it as small as possible. In theory, this profile covers all of the colors that modern monitors can realistically be expected to display without clipping, while simultaneously minimizing wasted bits and thereby minimizing banding. It uses version 2.1, sets the white point at D65, and borrows the gamma curve from sRGB. Gemini created Python script to generate the .icc profile itself. Copilot was also used to review, critique, refine, and ultimately validate the approach. Per the LLMs, this union profile expands beyond SRGB by 52.8%, beyond P3 by 12.7%, and beyond aRGB by 13.3%. It is 38.2% smaller than ProPhoto RGB.

The CIE xy coordinates are:

Red: x:0.6800, y:0.3200 (the same as P3) Green: x:0.2125, y: 0.7368 (custom) Blue: x:0.1500, y:0.0600 (the same as P3)

I'm interested in hearing whether this profile works well for others and the conceptual risks and pitfalls of this approach (putting aside general color management concerns, which will always arise when using something other than sRGB). Thanks!

>Flickr has grown into one of the biggest photo collections on Earth. It contains tens of billions of images from people all over the world, and keeps growing every day. That’s why we’ve created the Flickr Foundation—an independent, community-focused organization. We’re committed to stewarding this cultural treasure for future generations, and fostering a visual commons we can all enjoy. [1]

And

>Today, the Flickr holds “tens of billions of images” documenting our planet from the first days of photography to just a moment ago. What if—should the ship go down—we had an archival copy of your Flickr presence ready? Simply admitting this might happen and preparing for it is a form of preservation. We call it a data lifeboat.

You have probably been affected by web services that go dark or disappear, often with little or no warning. We think that’s not good enough, especially for an archive as precious as Flickr (and your photos), so we want to design a better way.

It’s all at risk—though not in imminent danger—and that’s why the foundation has been set up. SmugMug has acknowledged the risk and set us the task of imagining and determining how to make sure this huge piece of human history doesn’t sink.

We will work initially with the smaller and openly-licensed subset of imagery held within the Flickr Commons. Using this collection as our baseline, we will explore the edges of what’s required to create a data lifeboat that’s transportable, buoyant, and robust.[2]
