@max77sabers Very interesting. The alternating pixels raises questions about how it will perform in terms of resolving high frequency detail, as well as potential concerns for shadow noise if some portion of the photosites have some kind of ND filter or reduced shutter time. No free lunch?

@GregBenz this is worth reading x.com/petapixel/stat…

@brandon_brown83 @5DayDeal Glad to hear it, and thank you for your support!

@5DayDeal @GregBenz I highly recommend purchasing Greg's luminosity masking panel, "Lumenzia". Even though I am just a hobbyist photographer, It was a game changer for my photography.

We’re zooming in on @gregbenz, proud to feature them in the Photography Bundle! Pre-Sale launches Oct. 11th @ 12 PM PT + a $10K+ Giveaway! 5daydeal.com/twitter #5DayDealPhoto #DroneLife #PhotoEducation #CallingAllCreatives #PhotoMaker

Roughly 1 billion devices are set to gain HDR photo support for browsing with the upcoming updates to Safari / WebKit: gregbenzphotography.com/photography-re…

@max77sabers Yep!

@GregBenz ok for real this time, Safari gets HDR image support webkit.org/blog/16993/new…

@DSCCRoss Makes sense, thanks. I wish there was greater use of clear metrics / DisplayHDR certification to clarify OLED ABL performance in these announcements.

@GregBenz 1600 nits for HDR. Hard to say for 100% window. Should be brighter than other OLED laptops' full screen brightness due to the tandem stack...

Impressive new foldable laptop from Huawei...First laptop with LTPO, also has a tandem stack. fonearena.com/blog/453956/hu…

@DSCCRoss Whoa, that’s the same screen? Yikes, missed that.

RGB OLEDs without using FMMs are getting larger. Visionox showed 14.2” displays using their ViP technology/AMAT’s MAX OLED technology at DisplayWeek. Very bright but some noticeable color shift…

@DSCCRoss The IR camera under the display at the TCL booth is very interesting, very well hidden.

At the SID Business Conference today, OTI Lumionics CEO Michael Helander confirmed that they expect phones with under panel Face ID using their materials to be available for sale in 2026. This suggests that iPhone 18 Pro models will have under panel Face ID with other brands and models to follow…

@DSCCRoss Hoping to see QDEL

Are you looking forward to seeing the latest displays on the SID Display Week show floor? The event is right around the corner and you don’t want to miss the latest and greatest displays which will appear in cutting edge devices in 2H’25, 2026 and beyond. Register for free with my discount code DW25ROSS. It is much more impactful to see these products in person rather than reading about them. I am expecting/hoping to see: - High efficiency blue OLED demo’s; - The latest electroluminescent quantum dot demo’s; - The latest microLED developments including transparent, larger and higher brightness displays; - Previews of 2026 OLED TV panels from LGD and SDC; - Larger foldable displays as suppliers prepare to supply Lenovo, Apple, Samsung in volume in laptop/tablet markets; - OLEDs patterned with lithography rather than fine metal masks as this technology gets closer to market which generates larger aperture ratios, higher brightness and longer lifetimes. - Initial products from the world’s first G8.7 OLED lines with high mobility oxide backplanes. - And much more What are you hoping to see?

@ssh4net @BlurBusters HDR can also be encoded without a float. A 10-bit AVIF is 0-1023 int and maps to 0-10,000 bit code points in PQ. Adobe JXL is 16-bit, so might be half float if JXL support. Or might just use higher resolution for the PQ curve. I’m not sure.

@GregBenz @BlurBusters Well, it’s easy to check using jxlinfo from jpegxl project. If this is a uint8/16 than that’s a gain map (uint images have closed range 0-1) If this is 16bit or 32bit float than this is HDR (open range -∞ +∞)

For HDR fans, good news: HDR is now supported by Safari Technology Preview Version 125. - AVIF HDR - JPEG XL HDR - WebGPU HDR (not WebGL or Canvas2D) These are currently supported by Chrome/Edge. Good to see more widespread HDR+HFR, given boom of OLED & MiniLED gaming monitors!

@ssh4net @BlurBusters You could do either with a gain map. Adobe actually encodes the base image for JXL as HDR and then has a map to render SDR. This is ideal long term to share HDR with a small map. You can confirm using the Adobe Gain Map Demo app.

@BlurBusters @ssh4net I have seen Apple software bugs specific to various colorspaces in the past, so definitely something to watch (P3 tends to be most reliable / bug-free, which makes sense as their default space)

@ssh4net JPEG non-XL + gain map = FAIL JPEG XL HDR = PASS Not sure what type of HDR method that specific JPEG XL file at @GregBenz uses; maybe he can answer?

@BlurBusters @ssh4net I may have some old JXL image encoded with a CLI tool, but haven't done that in a while.

@BlurBusters @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz Lightroom on the web now supports live HDR edits and display (works in Safari Tech Preview 215, regular Safari does not show HDR)

@GregBenz @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz Does any website create a WebGPU canvas and draw HDR images via WebGPU APIs yet? (Not Canvas2D, not WebGL, not HTML IMG elements). I will be testing direct WebGPU rendering in the near future.

@BlurBusters @GregBenz @ctcwired @MishaalRahman @dylan_raga Safari finally getting HDR image support! webkit.org/blog/16523/rel…

@JeffreyBlanz @BlurBusters @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz I've got those enable, but see no images rendering as HDR. Have you?

@GregBenz @BlurBusters @max77sabers @ctcwired @MishaalRahman @dylan_raga

@max77sabers @BlurBusters @ctcwired @MishaalRahman @dylan_raga @max77sabers Thanks! Have you seen a path to making it work? I've checked multiple images with dev flags enabled in Safari TP 215, but no luck. I see a failed test in WebKit, so maybe not live? Or maybe MacOS beta also needed?

@BlurBusters @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz Is there a similar request for VMWare?

Y'all (Greg, Jeffrey, et al), I need help: Parallels virtual machine for MacOS does not yet support HDR Windows gaming. Help upvote to tell Parallels to add HDR support: 1. Register for Parallels Forums: my.parallels.com/login?service=… 2. Read HDR thread: #post-888052" target="_blank" rel="nofollow noopener">forum.parallels.com/threads/add-hd… 3. Vote for HDR support: forum.parallels.com/posts/888052/l… They have a vote entry but it's WAY down on the 2nd page of priorities. If we can bump the priority of HDR ecosystem wide, including virtual machines, this will be helpful!

@BlurBusters @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz @BlurBusters Are you seeing support? I have all the HDR and GPU feature flags enabled in Safari Tech Preview 215 and no obvious file format works as HDR so far (JXL, AVIF, HEIF, JPG - trying various encodings of these).

@GregBenz @max77sabers @ctcwired @MishaalRahman @dylan_raga @JeffreyBlanz Try .HEIC if .AVIF is not working yet. Also, try testing WebGPU to display HDR images. It's possible you need both HEIC *and* WebGPU at the same time; not 100% sure yet.
