The readme suggests this is a Linux-first app and as HDR basically doesn’t work at all on Linux(?) I don’t think it’s very surprising that this app doesn’t handle it.
It does a great job for my purposes – describing which buttons to click over email or im.
My understanding of the landscape currently is that KDE Plasma is the only major DE that supports HDR. I use it for Steam for that reason.
Yeah I think I’m a bit outdated here. But I do think Linux hdr support is weak enough that many Linux-oriented apps are unlikely to do it well
HDR videos and games (both native and proton) work in both KDE and Gnome (and supposedly Sway and Hyprland, but I haven't tried either). I think support in KDE/Gnome landed in a stable release ~6 months ago.
The HDR experience on KDE is about as good as the Windows one. Last time I tried Gnome, there was no way to configure SDR and HDR brightness separately, but it was definitely still usable.
Yeah, it doesn't seem to be the thing for Windows. For example its capture hotkey is PrtScrn which has been the Windows built-in capture key since approximately the Bronze Age, and then there's modifiers for whether you want to capture one window or everything, and if you really want to get fancy the Snipping Tool, all of them already built into the OS.
Honest and maybe stupid question. What does enabling HDR on Mac actually does? I have Samsung Odyssey, and turning it on for me only slightly dims the brightness of the display and rather feels uncomfortable to me personally, so I keep it off. What benefits (or drawbacks) should I expect when having it on? I spend most of my time in my terminal, my editor (GUI Emacs) and browser. I rarely have to edit photos or videos, do I still need it, I wonder.
update: turns out, for my specific case of the display model, it seems it's better to keep it off, otherwise the colors are not as vibrant.
I don't know if these are compelling. On a Mac I think they are somewhat

Note: Pretty much all phones for the last 4-5 years take HDR images. Take a high contrast phone (sun in the background, something dark covering half the image). Then later, view in in your phone. At least on iPhone they have some "fade to bright" thing where they don't show the HDR instantly but they instead fade to HDR over 1 second or so. Once they the brightness up it will still be up for the next photo. If you get out of the photo app at some point it will reset and then the next time you look at a photos it will do the "fade to HDR" thing.
Note: that site seems to only work correctly in Chrome. In Safari, the images flicker between SDR and HDR in some semi-random way. Firefox, AFAIK, has not added any HDR support yet.
There's also this: https://threejs.org/examples/?q=hdr#webgpu_hdr
Should work on Chrome Mac/iOS, and Safari iOS. Broken on Safari MacOS.
This has been my experience as well, I've searched high and low for a screenshot software that supports HDR and found none. It's the sole reason I have HDR disabled. At least microsoft updated snipping tool now, but the usability is nothing close compared to Flameshot or Lightshot.
The Xbox Game Bar video and still images do support HDR. They were the first feature to support HDR on windows. More recently the Snipping Tool on 11 also supports HDR, but only the newer one, not the older snipping tool. If you get images in JXR (jpeg-xr) files then you have HDR, if you get over-exposed pngs/jpgs then it doesnt do HDR.
I did some Googling to discover if Qt supports HDR on MacOS. It looks like support is currently limited, but it is an area of active development.

Latest docs (search for "HDR"): https://doc.qt.io/qt-6/qvideoframeformat.html
This Reddit post: https://www.reddit.com/r/macapps/comments/1ibala5/ive_discov...
... shares info about a Swift-based screen recorder that claims to support HDR. (I have no ability to verify that.) That might work for you.
What does "HDR" do in a computer screen? We're talking about high dynamic range, right?
Flameshot is the best! I've been using it for 10+ years. I have it wired up to some hot keys in my window manager, and have it dump to s3 so I can paste around links to screenshots everywhere for work.
> and have it dump to s3 so I can paste around links to screenshots everywhere for work.
I wanted something like this too but I modified Flameshot so I don't need a bash script in-between.
Flameshot already has a feature to upload to Imgur so I modified that and also added some small things (like randomized file names, some new config options).
> Flameshot already has a feature to upload to Imgur
Didn't they remove it though? Because someone complained about "privacy" or something? Devs promised to bring it back as the plugin, but I wasn't following progress on it, I don't know if that happened yet.

This has got to be the "todo list app" for people who aren't app devs; mine [0] is for MacOS + launchd + hammerspoon and I use Shottr for annotation
Great software.
On a small note: This recent PR is both awesome and pretty funny to me.

Man I hope this delivers. I haven't been able to use Flameshot for over a year since switching to Wayland because weird shit happens with my multi-monitor setup.
I used to really like this software, and I still do. But there were a couple of dealbreakers for me.
1) As others mentioned, Wayland support. But it seems that it's gotten a lot better since I last used it. I resisted using Wayland for a long time because of several software breaking, but I've switched over now that most of the things I use now work (or because I've stopped using things that don't work).
2) it was broken for me with fractional scaling. This is the main reason why I switched, I started using fractional scaling on my second monitor and could not properly fix it for the life of me. I haven't tested it recently, but I just checked, and the github issue seems to still be open. https://github.com/flameshot-org/flameshot/issues/564
I wish ShareX was available on Linux https://github.com/ShareX/ShareX
Good news is there are ongoing efforts to make that happen; https://github.com/SnapXL/SnapX
ShareX (win) > CleanShot (mac, paid) > Fireshot
just video is waaay better in cleanshot than it is in shareX (and a bit simpler to set up)
it by default uploads screenshots to public imgur, which was surprising and a no go for corporate setting, you can change that in setting, but it is still wants too do too many things
I'm vaguely involved w/ ShareX, so take this however you want.
It doesn't as of a recent update (due to continued stability issues at Imgur). The default behavior is to not upload anymore.
Additionally ShareX pops up a big red warning telling you that you're about to upload. There are some forks (see: ShareNot) that explicitly remove any uploading, but by default there is a registry key, a setting, and a big warning that you can enable that disables uploading.
Same. I tried probably 6-7 different tools on Ubuntu before I found Flameshot. It was everything I was looking for.
Good to know.
It was number three for me, I stopped looking and sort of wondered if there was anything else out there better.
Indeed, I've been using for (2) years, ever since I switched to Wayland.
I used Flameshot for half a decade until about 2 years ago when I switched to whatever comes with KDE because I switched to KDE from Gnome. So no, not malware. It's just existed for quite a while.
Flameshot is great! It was one of the reasons I have not switched to Wayland. Although it seems now they have wayland support in beta.
The good news is a few lines of shell scripting, grim, slurp and satty can be combined to create a decent alternative.
Hit a hotkey, capture a region, get presented with a way to annotate it and easily copy it to your clipboard or write it to disk. I use it on a multi-monitor system and it works no problem with Wayland.
Here's an example from my dotfiles: https://github.com/nickjj/dotfiles/blob/master/.local/bin/do...
It supports capturing a region, a specific window or the focused monitor.
Flameshot with sway has been a nightmare for me. I have tried a couple of times but i have never gotten it to work. I have settled with grimshot. The biggest missed feature is the number annotator. It was so easy with flameshot to annotate a screenshot with 1-9 and then refer to each number in a document. I really miss flameshot:(
I think it's beta for a reason. I just tried the appimage for their latest release and it's behaving in the same broken way that I remember.
I have a multi-monitor setup with different size & resolution screens, so that may be a factor for the problems I'm having. Really hope it'll work someday.
Spectacle for KDE is also a good choice.
https://apps.kde.org/spectacle/
I found Flameshot to work flawlessly only on Linux X11 and Windows. Other platforms (Wayland, macOS) have problems.
Maybe try Spectacle. I use the OOTB Spectacle app on Fedora KDE. It has the same features as Flameshot and is .. well, native.
But on my Mac, I use indeed Flameshot, it's not ideal (the window is "shrinking" when a screenshot is captured), but it's better than any alternative I tried.
> Because it's a black box [...]. No source code available?
You know Shottr is only available for macOS, don't you? If source code is so important, why do you even bother using macOS?
I wouldn't install Shottr on any of my Linux machines, even if available. Despite it being objectively better than any available alternative. I'd recreate one myself if necessary.
But on a corporate Mac, where 99.999% of executed code is a black box, why bother?
Huh? I'm running kde plasma on wayland and flameshot runs like a dream come true. I hit the flameshot icon in the tray, it automatically selects the whole screen to save, or if I click it starts cropping wherever I move the mouse. It's like the devs read my mind for exactly what I wanted
I'm running the same, but for me it's definitely not a smooth experience compared to plasma + X. Indeed I resorted to clicking on tray icon because invocation from custom shortcut doesn't allow me to Ctrl-c (copy to clipboard). On the other hand, clicking from tray breaks Ctrl-s (save to file). Oh, well.
Every Wayland compositor has a different feature set, and KDE is one of the more open to implementing features. It's likely that other people have compositors that stubbornly refuse to implement screenshots for security reasons.
Honestly the best screenshot software I've used so far is KDE's built-in printscreen thingy. I think it's called Spectacle. Does exactly all of the things you want - easy copying of regions, recording videos of regions (Wayland only unfortunately), annotation, etc.
One of the few times in Linux land where the UX is actually significantly better than Windows or Linux, and there's basically no jank at all.
(The only slight jank I noticed is that on X11 the "Screen recording" button just ... doesn't do anything. No "you need Wayland" message. Just nothing. I'll give it a pass though because the rest is so surprisingly great. Good job Spectacle authors!)
I do use ShareX on Windows for video recordings but Spectacle is better.
Spectacle is great. I tried to switch to it from Flameshot a few months back since it has all the features that I use regularly in Flameshot but ran into an issue where it would 2-3 times longer than Flameshot to start up when starting it up through the CLI. I use keymapper to map all my keyboard shortcuts and starting Spectacle using Qdbus is very slow compares to flameshot, like 1-2 seconds of waiting after pressing the hotkey compared to Flameshot being instant.
Looks like someone found a workaround by having spectacle run as a systemd process and restart after closing though, I'll have to give it a try: https://discuss.kde.org/t/make-spectacle-launch-faster/38030...
This is my go-to screenshot tool for Ubuntu. I've even gone as far as replacing the default printscreen with this using Custom Shortcuts. Word of warning, however: it is somehwat buggy when trying to add more than 1 text boxes on the screenshot.
I love flameshot and use it at work all the time for ridiculously marked-up and snarky screenshots to send co-workers or attach to JIRAs. Part of me wants to believe the "flame" in flameshot is for flaming people, like yes, you see this shit here? How about a nice big arrow so you don't fucking miss it
Flameshot is the best. I don't know about HD, and maybe if I get a HD screen I'll find out, but right now it's the slickest
Shutter is great in terms of features. I just recently discovered it.
But its code... Thousands (like definitely over 10k) of lines of procedural perl. I had a feature in mind I wanted to contribute and I couldn't even scratch the surface. I doubt this software can evolve any further.

As a long time (accidental) Flameshot user on Debian Linux, I was surprised to just now learn that Flameshot is written using the cross-platform C++ GUI library Qt. I guess that explains how it works on Microsoft Windows, Linux (X11/Wayland), and MacOS!
Flameshot is great! I also use it to capture different language text in images that gets piped into tesseract for offline OCR.
It’s VERY GOOD…
But why the hell can’t we get pen smoothing? What if I want to use the pen tool but not make it look like I’m a child on several mediations?
The app has a constant item on the bar at the bottom. Quitting that quits the whole application, I couldn't find a setting to change this behaviour. But I could live with that if it wasn't for it somehow switching desktops when you start taking a screenshot. It switches desktop, goes back to the main one, then starts the set up. Of course that also means it takes a couple of seconds before the screenshot gets taken.
Funny, I found flameshot years ago looking for a Linux to Skitch. What’s lacking in the built-in tool?
I'm unsure what Flameshot on macOS has to do with Flameshot Linux? I used to use Flameshot on Linux, and it works great, though I've always found the built-in screenshot software for Linux good enough. The application doesn't work as smoothly on macOS and I wouldn't need a tool for screenshots if the built-in tooling was any good. It's like it was designed by someone who had created a screenshot for the first time in their life.
On my Mac all I see is a gray screen when I'm using the app. It used to work on my Mac until a year ago.
Was looking to see if anyone had mentioned ksnip. Agreed, it’s great.
anything would be better than win11 snipping tool, it is crazy that after win10 it stopped working across 2 monitors, you can only snip in one of the two monitors
Flameshot is excellent! I’ve been happily using it for years.
How do you resize a rectangle made with the rectangle tool?
If you have something to say, say it. People don’t have the time to go investigate, but maybe you have something interesting to claim with a source.
For all I know you found a way to tie some software to a politician you want me to hate, or the guy that wrote it donated to $50 to a cause you don’t like, or they murdered beagle puppies in some horrendous way. Just spit it out.
Yeah. This is like clickbait titles. They hate something something for something something reason and won't tell cos it's probably something small.
They leave the comment making it look like the person made something huge. Only to find out that they didn't use the coaster while drinking his chilled beer.
And I don't care about this instance, I am not going to look it up. I have far more negative vibes about the OP in question than Lightshot.
Very bad dark pattern I've been seeing more and more these days.
Lightshot is a cloud-first screenshot tool. This means you shouldn't screenshot sensitive information. That's all I could find.
Considering that there are many tools like ShareX where uploading the screenshot is a feature, I don't really see reboot81's poor attempt at "spreading awareness" as genuine.
This has the same issue as most screenshot software, it's out of date relative to modern devices. Every Mac laptop for the last ~4 years has an HDR display. Many windows devices are also HDR. But this app doesn't capture HDR.
I tried putting up an HDR image and then capturing the screen. All HDR brightness was gone from the image.
I get it's not easy per-se. It wasn't until MacOS Tahoe that Apple's own screen capture on Mac started supporting HDR. Windows 10/11, AFAIK, only supports HDR through the XBox Game Bar's capture. Apps like ShareX still only capture SDR.
I mostly bring that up because I have apps the draw HDR and spent some time trying to find ways to add tests that we're actually getting HDR on the screen using screen captures. I hit a wall and gave up (2021).
