If only they had not confused shallow depth of field with Bokeh (which is not the shallowness of the depth of field, but, rather, how out-of-focus areas are rendered), this writeup would have been much better.

Cool technology, though.
- jcampbell1 13y agoBokeh = shallow depth of field effects The author isn't the one confused.
- sib 13y agoBokeh is the quality of the rendering of out of focus areas. It's not just making something out of focus (or creating shallow depth of field). 'Bokeh has been defined as "the way the lens renders out-of-focus points of light".'
- chernand 13y agoHi, I am the author of the Lens Blur blog post and the sentence was indeed wrong as a result of multiple edits. Bokeh and shallow depth of field are indeed two different things. By Bokeh we mean that the blur is synthesized using a disk kernel, e.g. as opposed to a Gaussian Blur. The blog is now fixed.
- josephagoss 13y agoHey, is there any chance we can download the RAW data alongside the JPG file?
- chernand 13y agoYou can extract the computed depthmap, all-in-focus image, and focus settings from the XMP data of the jpeg. See https://developers.google.com/depthmap-metadata/ https://developers.google.com/depthmap-metadata/ for the depthmap format.
- dharma1 13y agoThat is awesome! But I think he meant the RAW image that hasn't still been debayered or saved in a lossy 8bit format (jpg) It made the news last year but I guess hasn't still landed? For post processing, the RAW is so much more useful than a jpg http://connect.dpreview.com/post/2707133307/google-android-api-camera-raw http://connect.dpreview.com/post/2707133307/google-android-a...
- kbrower 13y agoCompare HTC's bokeh or any other attempt at this vs Google's and you will see that there is definitely a difference in how the out-of-focus areas are rendered.
