This photograph is a LIE
Dec. 4th, 2018 11:15 pmThis is actually a combination of two photos.
I was shooting at the observatory last year in June, using an interval timer to do some experiments with star streaks. Lots of fun, very tedious compositing the photos! But worth it. What I did not know was that I caught a transit of the International Space Station!
But there was a problem: the dome was facing north. The photo was a great shot of the streak of the ISS, plus the blank back wall of the dome, the butt of the telescope, so to speak.
So yesterday evening I did a little Photoshop work, very little work, actually, and produced this.

I'll explain just how easy it was and show you the original under the cut.

The question is: is this altered photo still a photograph? I would say no, for the most part, I would call it a photographic illustration. If I were to sell the rights to it, I would make sure that the buyer understood that it was a composite, and I would show them exactly how I did it.
I tried doing it in the other direction by erasing the back-facing dome, which would mean the star field would be true to the time of when the ISS transited, but the sky's exposure around the dome was different as it was 40 minutes later. It just didn't work.
Even though this video isn't from that shoot, it shows what I was trying to accomplish.
Here endeth the lesson.
THIS was the end result of the shooting of that night:

This last photo represents a composite of 298 photos shot from 10:16pm to 12:51am! During that time the telescope observed many different objects, thus accounting for its spinning back and forth like a dervish.
