Gearing up for 2015 With a ProtoMachines LED2 Light

One of the primary things to manage during night photography are your light sources. You may have light pollution from near or far incandescent light, additional light from the moon, a strobe (flash), and handheld lights such as a colored LED, flashlight or headlamp. Illumination from various types of lights ranges from "cool" (blue in tone) to "warm" (yellow). Fortunately you have a lot of flexibility to adjust the warmth or coolness of the lighted area in post-processing software such as Lightroom. On the other hand, it's good to do as much in-camera as possible, so if you can tune your light to have the desired effect while you shoot, that can save time on the post-processing side.

The result of a quest for warm, cool and colored lights
I've posted on the variety of lights I've bought, used and carry, but at some point carrying so much gear gets to be a bit of a burden, especially when moving around cluttered scenes on dark nights.  Even trying to keep costs low, over time I've ended up spending a fair amount just to have a selection of different light temperatures and intensities.  And the selection is one of compromises, incandescent lights being seen by the camera sensor as being very warm and yellow, while most simple LED lights are seen as very cool and blue.

After having customers show up at my Bodie night photography workshops last year with ProtoMachines LED1 and LED2 lights last year, I just picked up an LED2, which should dramatically reduce the volume and weight of the light painting gear I carry, give me a wider range of options, and reduce the number of batteries I need to keep charged.  I can pre-program warm and cool settings for a range of white balance settings, or various RGB values for creative color work.  The intensity can be adjusted in a range of up to 9 stops, so the brightest setting should be 2 to the ninth power brighter than the dimmest one, a range of 512x.

It's going to be nice to have a light with adjustable color and intensity, all in one small package.  It'll be fun to see what works best for lighting up foreground subjects under full moon, no moon, and mixed lighting scenarios!

Applause for the Appulse: Moon, Mars and Venus

I thought that I was having a good day to catch some nice photos of the crescent moon by Mars and Venus last month, setting behind Mount Whitney.

Then I put a sequence of photos together in a time-lapse video, and the event came to life!


I posted a link to my Twitter account @JeffSullPhoto, and +Philip Plait embedded the copy of my video on Vimeo in a post on his +Bad Astronomy blog on +Slate:
"Venus, Mars, and the Moon Go to Sleep".
He tweeted a link:
Then the +California Academy of Sciences tweeted a link as well:
It's cool to have astronomers and scientists recognize and share my astrophotography!  Check out Phil's blog post if you have the time.  He always adds some nice scientific context.  What most of us call a "conjunction" is actually called an "appluse".
