I'm using Capitally (https://mycapitally.com) which I started building to replace my 3 spreadsheets that needed constant attention and broken down quite often. It now completely covers tracking my investments - spreadsheet nr 1, still two to go - portfolio strategy and budgeting.

They recalculate the blur. Were you asking about calculating the depthmap?

I will add <span ng-if="Modernizr.Android">another </span>Android ;)

There is an app for iOS - seene.co. The amount of movements you have to do to capture enough pixels is prohibitive for my taste. I think that google has nailed it - it's super simple.

As for storing the layers - you would only have the "from above" pixels, and only a few. Probably that's why there is only a LensBlur in their app in the first place.

If you just want a small displacement effect like on depthy - then the key is no sharp edges in the depthmap. We will try to tackle this in one of the upcoming updates...

Yes, here: http://jabtunes.com/labs/lensblur/index3.html and here: http://quasimondo.com/QuasimondoLibsJS/demos/DepthMapLensBlu...

On iOS you have the icons as a first plane - that makes the trick.

If you have an Android device around, try depthy on it - it's way better this way imo.

Fog, refocus, background separation, chroma shifting.

As for the fill, if the depthmap is of good quality and without sharp edges - there is no need for that, unless you go berzerk with the scale of displacement.

There already is a library for extracting the depth map here: https://github.com/spite/android-lens-blur-depth-extractor (internet rocks, isn't it ;) )

As for the Shader - it's just a few lines of actual code.

Depthy is a quick weekend hack. There's a loong way before it.

It's exactly that - single image, and a depth map calculated from a series of shots made upwards. Both these are bundled in a fake-bokeh image. There is obviously no more pixels. However... If you choose your subject wisely, the effect can be pretty believeable, using a simple displacement map.

On iOS though it's something different. There's no depth map in there, just a flat image moving counterwise to your hand movements.

I've created a parallax viewer for lens blur photos. It's an open source web app available at http://depthy.stamina.pl/ . It lets you extract the depthmap, works on chrome with webgl and looks pretty awesome on some photos. There is quite a few things you can do with this kind of images, so feel free to play around with the source code on github https://github.com/panrafal/depthy
