Lytro minimum focus distance: get Super Macro shots in Creative Mode

Lytro minimum focus distance: Get Super Macro shots in Creative Mode As we told you earlier, you can get as close as 4 to 5 inches (10 – 12 cm) to your subject with a Lytro LightField camera. That is, if you take your picture with Standard Mode.
WIth the recently introduced Creative Mode feature, you can get even closer – much, much closer:

Lytro writes:

In Creative Mode, there should not be an issue with “too close.” Ren, our founder, even shot a bug crawling across the camera lens.

That means, the minimum focus distance in Creative Mode is basically zero, if your camera is fully zoomed out. With maximum zoom (8x), the minimum focus distance is about 3 feet (1 meter), which means you should be able to get cool close-up pictures of animals etc., wich a more narrow depth of field (equals nice, blurry background).

Here’s Lytro’s video introduction to Creative Mode:

…and an example Living Picture that shows you the extreme macro power:

Has Lytro drastically modified the pictures in its official LightField gallery?

The pictures in Lytro’s Living Pictures Gallery look awesome: They’re beautifully composed, show little noise and have full, saturated colors. Obviously, Lytro will show off its best pictures to get people interested in its new product, but are these pictures really representative of what comes out of your Lytro camera?

It seems that at least some of the pictures in the official gallery were significantly post-processed in order to give them better color and saturation:

For comparison, have a look at the official and original Living Pictures.

It’s obviously possible to do post-processing with LightField Pictures. Is the above an example that it’s not very hard to do, and that we’ll soon also get the chance to postprocess our Lytro pictures?
