|Solar Eclipse 2015 - Experiences and results
3. My experiences and results
My camera was set up and adjusted quickly, while the rest of my family devoted itself to the event
(see: Fig. 32 last page).
I got no problems with the first shots. And I even could identify a sunspot on the full solar disk.
(see: picture sequence on the left, Fig. 33).
An test series suggested that the best pictures will arise with a point-metering.
The standard self-timer was sufficient to prevent blurred images.
I could achieve an approximately good picture quality assessment by using the electronic zoom of the display.
Since I was working without tracking, I had to adjust the camera after every third image anyway.
But there were also unexpected problems:
Every now and then the autofocus refused its service.
I guess, the reasons were, either some haze in the sky or the uneven
solar protective filter at my camera.
In this situation, the automatic trigger lock had proved useful.
I shot fewer but reasonably sharp images
and the overall situation turned out to be less stressful.
Overall, with this setup the limits of my lens, respectively
focus, distortions and color fringing, have been exhausted to the extreme.
At 10:45 CET, when the maximum of the eclipse was exceeded, suddenly most of the amateur photographers
packed their equipment and departed.
It became silent at Ludwig's-tower.
Just now, I noticed that the temperature had fallen remarkably.
Of course, the moon stops the radiation emanating from the sun -
the thermal radiation - which actually represents the lion's share of solar spectrum.
For the next hour I calmly documented the continuation of the solar eclipse.
Later I found, that it was bad to change my location around 11:00 CET.
I wanted to prevent, that some treetops came into my pictures, while looking at the sun.
A total of 110 images were taken in the 2.5 hours. I chose ten for the illustration of
the penumbral solar eclipse event (see:
picture sequence on the left,
( Fig. 33).
Almost all images include the sunspot, except for those in which the black
Moon obscured this. It appealed to me to have this spot as a reference at all of my images.
To achieve this I had to change my originals in a tricky way by using the software photoshop:
I overlaid my first image of the uncovered sun with all selected photos, declining their blackness by 50 %.
By this the moon will no longer appear completely black and the sunspot gets visible.
