Thank you for sharing your pictures with me. None of those pictures have any refocusability because they are all prettymuch at optical infinity; if you want refocusability, you need to start thinking in 3D! You want to conceive of, compose, and shoot your picture so that it contains something in the foreground, and you need to be close. In everyday mode at 1x, Really close! I'm talking 6 inches. As you explore using the zoom, you want your nearest object to be further away too.
Here's an example of a couple of pictures I took not so long ago:
I guess what I would say is this:
There's a learning curve. I recommend reviewing the following resources:
- Our ** learn page** has some great videos
** Understand the basics** of shooting good light field pictures
There's a fun ** set of challenges** that will also teach you compositions we do well in.
As far as whether or not your expectations were too high, I can only say that the Lytro camera was not designed to replace your point-and-shoot or DSLR; it is a second camera you're going to use to explore the new possibilities that only Lytro can bring you in 3D composition and story-telling.
Finally, refocusability is just the *first* thing we have released. We have other exciting light field effects we'll be releasing in the months ahead: perspective shift, 3D output, all in focus... and you'll be able to apply those effects to all the light field pictures you've taken. But... in order to get the most out of those future effects, you need to understand how to compose a good light field picture. In that sense, it's no different from traditional photography: learning technique is the most important thing of all.
UPDATE: Perspective Shift has been released:
