In camera double exposure, basic edited.
70-300 and tripod. f11 and 350 iso 400 300mm for the moon
f5.6 and about 3 sec 70mm for the lake, no filter.
Yep, I know that the light is backward on the moon,,, and that's why there's no reflection ...Ha.
Not legal for basic
You may: use any feature of your camera while photographing your entry, with the exception of combining multiple captures in-camera.
May be legal for Advanced, difficult to know, you can use ANY feature of the camera BUT you must create your entry from 1-10 captures of a single scene (defined as a scene whose composition/framing does not change)
You'd need to go to SC for clarification I think!
You could get around it by using an ND filter to create a really long exposure and then cover the lens halfway through the shot, recompose and remove the cover. You'd have to overexpose and probably a lot of trial and error but it would be legal as it is a single capture
