Apple limits TestFlight to 10,000 testers. Folks who are paying a recurring fee expect to see more frequent updates, so they get priority. Halide shouldn't be afflicted by the lost photo issue you're talking about. Normally, if

We switched to Apple's StoreKit 2 framework, which uses different internal plumbing. Not only is it the recommended way moving forward from Apple, but it improves the user experience for purchase management. The issue is that, indeed,

In May, we launched Mark III, which was a huge rewrite and leap forward in features. https://www.lux.camera/halide-mark-iii/ As for the subscription, there’s always been a pay-once option for major releases. You just m

If the sunflower and Osaka photos aren’t in HDR, there’s something off with your system. Make sure you aren’t in low-power mode. Fun fact: the HDR photos are actually looping videos, because that’s way more reliable for browsers and CMS pla

Grain will definitely be tweaked! It landed late in the release cycle, and I want to give it more love before the final launch.

Hey everyone. Halide guy here! This post came out a few weeks ago. To answer your question in advance, your favorite thing from Mark II that’s missing is eventually coming to Mark III. I’m right now on a short detour updating our video app,

This post is written for people who have heard "HDR" and feel confused. That introduction lists two types of HDR people might think about. "The first" means "the first of two types we're going to explain,"

You opened this thread arguing that Ansel Adams didn't "use HDR." I linked you to a seminal research paper which argues that he tone mapped HDR content, and goes on to implement a tone mapper based on his approach. This all s

In theory PQ specifies absolute values, but in practice it's treated as relative. Go load some PQ encoded content on an iPhone, adjust your screen brightness, and watch the HDR brightness also change. Beyond the iPhone, it would be rid

Thanks. Updated.

I don't think that's the colloquial meaning. If you asked 100 people on the street to describe HDR, I doubt a single person would bring up ITU-R BT.2100.

Human vision has around 20 stops of static dynamic range. Modern digital cameras can't match human vision— a $90,000 Arri Alexa boasts 17 stops— but they're way better than SDR screens.

No. When you simply adjust shadow and highlights, you lose local contrast. In an early draft of the post, there was an example, but it was cut for pacing.

While it isn't touched on in the post, I think the issue with feeds is that platforms like Instagram have no interest in moderating HDR. For context: YouTube automatically edits the volume of videos that have an average loudness beyond

By definition, a RAW container contains sensor data, and nothing more. Are you saying that Adobe is using their proprietary algorithms to render proprietary RAW formats in Lightroom?
22.
by sandofsky 1y ago
Hey. I’m the guy quoted. RAW is ultimately about sensor readings. As a developer, you just want to get things from there into a linear, known color space (XYZ in the DNG spec). So from that perspective, interoperability isn’t the issue. How

Raw decoding is an algorithm, not a container format. The issue is every is coming up with their own proprietary containers for identical data that just represents sensor readings.

We have never, ever locked away Halide from people who already purchased it. If you bought Halide 1.0 in 2017, you can still use it today, with all the features you bought, without paying another penny.
