Re: analemma

Hi Matthew,

Thanks for the kind and encouraging words. It is really more than a year's worth of patience since nothing of course works the first time out. I analyzed this project to death prior to starting out and, yet, six years later I am still at it with the last (problematic) analemma. Just to give you an idea with this final analemma, I accidently bumped the permanent camera mount in April and which meant yet another (immediate) restart. The analemma is such a beast that the slightest oversight or error will prove to be catastrophic when the year is up and the film developed. To add insult to injury, you are always working in the dark, sort of to speak, since you never know if the analemma in progress is fine so far or whether something has gone wrong.

My first taste of success was in my second year of this project when I had two analemmas complete successfully. With each passing year, a few more would prove to be successful and I am now at a stage where I am a step away from having a complete set of analemmas from sunrise to sunset.

Anthony.

I appreciate the analemma images you shoot, because it takes a lot of
patience to do it.
One entire year of images with a camera frozen in place, and hopefully
secure from thievery.

The tilt of the analemma can give you your exact latitude and the UT time of
the exposures along with lens data can define the longitude. Each analemma
is specific to the exact location it was recorded.

Dale,

All of this information is available anyway since the analemma itself
was not touched in the slightest.


If you paste it into
another location, especially a well know tourist spot, it loses all meaning.
The tilt and elevation doesn't match the location.

I am not sure a "few" kilometers deviation from my location would change
anything in relation to the tilt and elevation. In fact, I used a 24mm
lens and whose image scale would probably hide any such differences
(this was not the reason for using such a lens).


The scale is changed, the
whole thing is meaningless. The whole point of the analemma images is the
information they contain and it is location specific.
The images are artistic but the science is lost.

I disagree that the science is lost since the analemma was not touched
in any way. In fact, if I did the unthinkable and stated that everything
was taken on a single frame of film, it would be possible on the basis
of what you write to prove the converse ... which is music to my ears
since it gets back to my original comment that the analemmas were not
touched and, therefore, the scientific information is not lost or
altered in any way. Yes, it MAY be in partial conflict with the
foreground "data" but that is where my vice ends.

To be honest with you, a bigger "problem" is the fact that the analemma
and the foregrounds are not always in the same direction/orientation. My
primary objective was to image a foreground where the sun can be found
physically during the course of the year (ex. due north is out of the
question). My very popular analemma with the Ancient Nemea foreground
involves an analemma in the late afternoon whereas the foreground is
approximately 180 degrees in opposition (ie. due north-east) and which
would have been more applicable for an early morning analemma.
