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 sure how Adobe is implementing their RAW editing)

-- The main idea of the company is in fact automated photo retouching https://www.polarr.co/box (please use desktop, large videos), and we applied to YC with the idea.

How are you going to solve the performance issues if JS's type is only 32 bit? I could see the possibility of mixing multiple JPEGs but extracting that probably takes you a minute in processing

Do you use a three level hiearchy on the image? I assume you guys first down sample to full resolution preview(like 600x400) and a low resolution preview. When editing, filter applys on the low resolution preview and then full resolution preview (1.5second latency). When exporting, you apply all the filters on the original image. Is it the case?

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 mediocre UI in comparison to something that has had real thought put into it.

(But again, that’s nothing unique to this app. Adobe Lightroom takes the same lazy way out. Several of the tools that have been in Photoshop since before 1995 are a bit more powerful/flexible, but everything they’ve added in the past 20 years seems to follow the wall-of-sliders model. Some expensive professional video color grading applications are a bit better, but still nothing too special.)
