I used the following setup
to take two pictures of the supermoon yesterday. One with the moon properly exposed:
and one with the wooden puppet properly exposed (but the moon blown out):
I tried combining these two pictures in Photoshop CS6 using roughly the following steps:
- Add the two images as layers
- In the image with the puppet, make the blown out moon transparent
- Use Free transform with shift pressed to fit the moon in the 'cutout'
This resulted in the following image:
But I am not totally happy with that image because of
- the white halo around the moon
- if you zoom in, you see the edge of the moon is very pixalated
Is there a better way to merge these two images? Also, if I wanted to do some further postprocessing on the moon image to get some more contrast etc, would it be best to do that before or after merging the images? For reference, the RAW image files of the moon and puppet.
The new result, after following the steps as explained by Vincent:
