Show HN: Make your logo extra bright on HDR screens

Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them.

I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site.

I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful!

Oooh fuuuuuuck. Do we now have the HDR screen version of the 90s/00s CD volume wars? MAX IT OUT?!? BE LOUDER! BE BRIGHTER! WTF.

It goes up to 11

This is fun and will try to embed it in our project next week.

I just noticed something similar today as an ad where the green oval button was so bright that the rest of the white screen felt grayish/dull than white. It could not be unnoticed playing on the notion that the eye is attracted to the brightest thing on the screen

Please don’t do this.

You know it will be annoying.

On the other hand it’s a great signal that whoever uses that is an obnoxious twat and should be plonked.

Pretty sure Fifth Star Labs’ Sky Guide iOS icon does this. Not the whole icon, just the stars in it. Hiding the app in a folder helps but I’m looking for a better alternative just because of this.

Uninstall the app? Leave a review, tell the developer.

I mean, use it responsibly. Of course people won't, it's the internet, but a skilled designer may use it to highlight a word or an accent to draw your eye. It can be tricky in dense interfaces to draw focus to something (little tooltips or big buttons aren't the best answers). This is just another tool in the toolbox.

It’s bad because it dims the entire display. You’re assuming your app is more important than whatever else might be displayed. It can also take a bit for the os to go back to the sdr state. I’ve had a few cases where safari gets stuck in hdr mode and won’t revert u til I force closed.

The page says it should work on my phone but it doesn't. No difference between the SDR and HDR versions on my phone (S26 Ultra / Chrome).

It also depends on your screen brightness. In my case, if it’s set to maximum, there is no difference between SDR and HDR.

Came here to say this. It just cranks the brightness up for the pixels. But if you are already at 100% there is not much headroom so all the "before and after" for me were pretty hard to differentiate. There was some minor difference if I studied it closely but I'd probably not notice it during normal use it was so slight.

If I went down to say 50% brightness then it was much more pronounced, but who lives their life with their eyes only half open like that?!

telecuda•8m ago

That's what I'm finding as I researched it:

Android's HDR brightness slider is low - The single most common "HDR does nothing" report on Android 15/16 devices. Samsung also has Super HDR/Extra brightness / Vision booster toggles under Display. Any of them at the conservative setting would have an effect.

telecuda•35m ago

I was only able to test it on my iPhone. Let me see if the S26 needs a tweak (or confirm if it's not support)

telecuda•40m ago

Works for text too!

> Every social network strips these tags except the worst one

> Clearly we need more of it

I do not in fact want sites trying to get around my display preferences to post their visual presence on screen.

sbustelo•35m ago

It seems you have seen the same logo in LinkedIn that I did :)

Waddabout an ImageMagick command or explanation how to export in Inkscape?

daigoba66•16m ago

I’ve noticed this trend on LinkedIn just recently. Very noticeable at night, obviously, when my screen is naturally more dim. But these logos are like blinding headlights.

uhoh-itsmaciek•15m ago

In Firefox, the page tells me neither my browser nor my display support HDR. In Chrome, it works fine. Latest browsers on a Pixel 8.

nvr219•14m ago

I noticed this as well on Firefox and I say, good, please don't fix.

If you use HDR videos, you can get bright white even on soon browsers that don’t support HDR images
