You know how it is – a full moon on the horizon looks huge, but it shrinks as it rises. It’s inconsistent too: it keeps changing shape and it moves around the sky. So how do you get those Hernandez shots with a perfect moon in the perfect place?
With Photoshop or Gimp it’s easy enough to combine a moon shot with a foreground, but you can do the same thing with film too.
I got the idea years ago; from someone else, obviously. I was reading something from a photographer whose name I am afraid I have forgotten. He was off on honeymoon and planned to shoot landscapes to cover some of his costs. To make them special he shot one roll of film with full moons to double expose them later. But let’s get to the method…
The idea is to mark and load a roll of film in such a way that you can line it up to shoot the frames again as double exposures.
The first thing to do is to mark the inside of your camera. Load a film, keep the back open and make sure the film is lying flat and tight and the camera is fully wound on. Mark the film with a pen to match the camera marking. Close the camera, wind on two frames and start work.
Next, you need a moon and a notebook. The idea is to take a full roll of shots, placing the moon in different parts of the frame and at different sizes and noting these plus the frame number.
How do you expose the moon? Easy – it’s in bright sunlight so you could Sunny 16 it on a clear night, although to be more accurate you need to give it an extra stop of exposure using the perfectly named Loony 11 rule. How do you find when the moon is full or crescent? An ephemeris.
Carefully rewind the film, keeping the tail out of the cassette. When you want to use it, reload and line it up with the marks again. Fetch your notebook and look at your notes. Use a polariser, filter or time of day to render the sky dark, or at least darker. Expose and shoot for the foreground.
With luck and a fair wind, you will get big moons in your skies.
Playing with the focal length of the lenses you use for the moon pictures and for the overlay changes the relative sizes and can give you the big moons you wanted. It can also look totally false or you can mess it up completely, but that’s how we learn, right?

That’s a interesting technique, and the pictures turned out really well 👍
Thanks. Plenty of glorious failures too!
