Dual pixel raw can make interesting 3D image

Thanks Hans van Eijsden for providing the dual pixel raw file

Typical 3D lens is low quality lens with high f number not suitable for fast action, this can make something interesting? - such as no 3D lens made for Canon on market can give this sharpness?

Not everybody is interested in 3D, and one picture cannot tell if it works well for 3D under all situations but if it is free why not? The information is there, who knows if it could became useful months or even years later after the picture was taken?

First, people find it may increase dynamic range, now it is proved that it can do 3D to some extent at least, what's next?

Very cool! It actually works. I'm curious as to what other applications this may be used for.

Personally, the DPR itself is useless to me, I see it more of an advantage for macro folks.

Very cool...but grrrr...the proper term is stereoscopic, wish people would use that. I'm surprised that you have sufficient interocular distance for good parallax, but I suppose I shouldn't be. Lytro cams did this same thing.

Oh wow this is great. It's really exactly looking as if I was in front of it when I took that photo. Thanks!

Thanks for teaching me the correct term.  

I was just using the bokeh shift function to create those pics.

I can conclude that it is not just the bokeh shifted - the image that is partially in focus also shifted. The fully in focus part of the image shifted very little if any. When scaled down to 4K or less, the partially in focus portion of image looks reasonably sharp.

After looking a bit more, there may be extra depth information in focus shift function that can be utilized to improve the stereoscopic effect. If  include the difference in the out of focus area  between front and back focus - the difference is not just limited to the shallow zone where the image is sharp. (some form of depth map may be created base on this)
