This afternoon/evening it was Quiver trees again but in a different location & this time we shot sunset and then tried star trails. We have left our cameras set up to take a 4 minute photo with 1 second intervals until the battery runs out. This Quiver tree forest is on private property so the gear should be quite safe.
I won't bore you with all the technicalities, suffice to say it's very fiddly when you are trying to shoot the sunset and then quickly set up for trails. The hardest part is finding a good composition. The picture has to stand alone without the star trails; they should compliment the picture, not be the picture.
