Dev of Polarr here. I think the biggest thing that's missing from the current release is RAW image support which is technically difficult to do. We're right now having some success of extracting the thumbnail of RAW and do it on the client side only using JS, but editing the RAW is a lot harder and we're thinking about using some WebGL texture blending. Any thought/comment on this is welcomed and appreciated. (Not su…

Have you thought about compiling dcraw to javascript with emscripten? I'm not sure what the performance would be like, but I've seen this work in the past.

The front-page of the website is extremely laggy for me. I'm using the latest Firefox with Arch Linux. The framerate drops down to about 1 or less. EDIT: The app itself is fast.

Yeah the home page is a disaster, super laggy and the photos are even revolving over most of the 'read more' text so I can't even read about the features. Please think about redesigning it.

Could you make it faster still by compiling to asm.js? I'm not sure how it would apply to you, but I know Mozilla has been bragging about how WebGL games are faster with asm.js.

It's using very heavy CSS3 transition for the homepage that causes the frame drop. Will detect that and avoid that from happening. -dev

Neat webapp, quite impressive. Still, I’m disappointed at how lazy the UI design of nearly all image editors is. They take off-the-shelf algorithms/models, implement them in code, and then slap a slider widget in for every parameter in the model. A big wall of sliders takes basically zero thought or effort from a UI design perspective, which is why it’s so popular, but other than being ubiquitous, it’s generally a me…

Do you have suggestions? When I look at applications oriented towards prosumers and professionals like this, photoshop, etc. I think the point is to give complete control to the user. I don't know anything about photo editing.

One can always take inspiration from audio software and audio plugins, some of those have quite slick UI ideas.

Great technology. I'm maybe a bit stuck in my RAW file processing ways to find a use for this myself, but I am impressed with it's speed.

A couple of things I'd like:

- Proper support for high-res images - it might be in there, but the demo flower image is web res - The hover-to-select mechanism from Lightroom. You only need to hover over a control to adjust it with the keys. Appreciate the tab support though. - Finer/coarser value adjust with the arrow keys. LR allows for modifiers to increase/decrease the value change.

Bigger asks: - Find some way of emulating LR's automatic lens correction. Using this still feels like magic. - Spot removal is pretty important - Other local adjustments would obviously be nice.

It might be nice to offer this engine as a technology plug-in sort of thing. I know at least a couple of clients who would love to be able to use this level of adjustment on the photos they upload to their Wordpress sites. I imagine there'd be some demand for this plugged in as an API'd service.

The code is GPU intensive but not quite CPU intensive so in this scenario I believe no. Certain WebGL games need their engine compiled into JS.

I'd try rawspeed instead of dcraw. Much faster and cleaner code and the latest version supports almost all cameras.
