APOD: 2018 June 4 – Moon Setting Behind Teide Volcano

“Explanation: These people are not in danger. What is coming down from the left is just the Moon, far in the distance. Luna appears so large here because she is being photographed through a telescopic lens. What is moving is mostly the Earth, whose spin causes the Moon to slowly disappear behind Mount Teide, a volcano in the Canary Islands off the northwest coast of Africa. The people pictured are 16 kilometers away and many are facing the camera because they are watching the Sun rise behind the photographer. It is not a coincidence that a full moon rises just when the Sun sets because the Sun is always on the opposite side of the sky from a full moon. The featured video was made last week during the full Milk Moon. The video is not time-lapse — this was really how fast the Moon was setting.”

Making simple double exposures in Photoshop

I found there’s no simple “just merge two photos together” option in Photoshop, and the File/Automate/Photomerge option hates photos that don’t fit together exactly.

The simplest way I found:
Load both photos into Photoshop.
Click on the Move icon (the four arrows in all directions).
Right-click on the tab of one photo and select Move to New Window. It will minimize slightly.
Drag that photo into the other photo. That creates two layers in the other photo’s frame with full opacity.
Reduce the opacity of each layer so you can see both layers for positioning.
Drag each layer into the position you like, and select the opacities. Full opacity will bring back the original for a layer, and 50% or so will make that layer a ghost image.
Select both layers in the sidebar.
Select Edit/Auto-Blend Layers. You may want to have Seamless checked.
If the settings look good, click Okay, and you should get the blending you want.
You may need to experiment a bit with the steps, but at this point you can do whatever other processing you want, and save.
