Day 27

Close-up Photography with Glass

Here's a series I took of some peach blossoms.  The first was taken from about 6" away.  Despite the large and centrally placed target, Glass could only focus as close as the branch behind, perhaps 9" away.  The open flowers are about 1" in diameter.

This second pic is from a little further back, about 9".  No problem with focus and the wide-angle lens provides crazy deep depth of field.  Unfortunately, the flowers of interest are already shrinking too far to show much detail. 

Taken from about 12", this picture again shows excellent depth of field but not enough detail for the small target. 

At 15" the peach blossoms are much too small to be a point of interest and we begin to see some washing out from the bright sky to the left. 

Must talk to Kent about the optics of a Glass close-up accessory lens.  I could try my old 50mm set of lenses from my Pentax K-1000 for a test series.  It would be most effective with video, since you can see the image being captured in the prism.  Speaking of which, it'd be nice if there was a preview option for the still camera.
