I should report you for publishing a photo that makes me drool about being there.
What a super shot. Where were you exactly for this shot (north or south rim drive?)? And dawn or dusk?
I still need to look up sun rise & sunset times for Oct 2 when I plan to be there.
I was at the beginning of the canyon at a pullout. The road in the lower left of the photo is where the tour vehicles enter the canyon.
I assume that it was the southern side as that is the moon rising. I got there before the day of the full moon, scoped out where the moon rose. On the day before the full moon, I set up in the pullout and waited.
If you shoot on the day BEFORE, you will still have sunlight on the sides of the cliffs as the moon is rising.
Full moon for this October is on the 8th.
