Morning skies and trees in visible spectrum and near IR.
Are the trees reflecting infrared, or are they radiating the difference between the incident blue and ultraviolet and what chlorophyl absorbs?

I have discovered that the camera connectors on the RasPi are rather fragile and have latching pins that are easily broken on either end. Fortunately, any bit of plastic of about the same thickness can serve as a substitute when clumsy handling takes its toll.

+sporadic -Z Oops, sorry.   I think Google resamples it down to 80M for streaming, but that's still too much for a phone without an unlimited data plan. I uploaded the 420M file. This video is about 3.4G in original resolution and speed after being saved as a .mov file.   The 13,000+ time-lapse jpegs take a bit less than 32G.   I'll see how much I can compress this.

near infrared Pi NoIR cams
one pointing northeast - complete spectrum
one pointing southwest - 25A red filter
I used a Quantaray R2 filter.
The pass band is similar to this Hoya filter.

What I may learn about is the fluorescence of chlorophyll.

Paul Ryan may have just proven himself to be the most accomplished political comedian we will see during this election cycle. I'm expecting Donald Trump to suddenly "get it" and explode with his customarily indignant rage when everyone realizes that "warm and genuine" so aptly describes the contents of a freshly filled diaper. The absence of an endorsement seems to underline this particular interpretation of the phrase. The magnitude of political correctness in this assessment of character is positively astounding. This may be a hysterical turning point for the Republican Party. It could completely reverse course and hastily retreat from the incessant pomposity of the recent past to embrace group self-deprecation. The micro-biome of the GOP has become akin to a severe and life-threatening Clostridium Difficile infection of the lower alimentary canal.

I imagine their meeting went something like this:

Ryan: Don't eff this up for me in 2020.

Trump: You mean 2024.

Ryan: ...

This time-lapse sequence was captured with OpenCamera running on an Alcatel OneTouch Pixie Glitz phone with KitKat 4.4.2 as sold by Tracfone.  This device was only $19.95 and does not require a contract or activation with prepaid minutes if you only want to use it as an Android gadget with Wifi and ignore it's phone capability.  It has a 2mp camera and GPS and can accomodate an SD card up to 32GB, but does not have motion, magnetic compass, or orientation sensors.  http://opencamera.sourceforge.net/

It's time I fished out the instructions for my cheap timer, and pointed my camera skywards...

Introduction

"Ah, arrogance and stupidity all in the same package. How efficient of you."
