The photo above was taken in Matane, Quebec, in September 2024. It’s more a matter of chance than planning. I was on the beach photographing the sunset, and when the sky got too dark, I turned around to see if there was anything interesting left to capture. And I came across this full harvest moon rising in the firmament.
Photographing a full moon is a good challenge. We often capture only an almost white, very bright disk, losing the nuances of colour and the details of the lunar geography.
The advice available on the Internet on how to successfully shoot a full moon with a normal camera goes in all directions. But one thing’s for sure: to improve your chances of success, it’s best not to wait until nightfall, because then the very high luminosity of the star becomes impossible to attenuate while still retaining a view of the planetary topography.
Most of the time, the choice is between an excellent photo of a full moon, but a very dark surrounding earth relief where nothing is discernible, or a visible earth relief of acceptable quality, but a moon that represents nothing more than a large, white circle of light.
The method that works for the photo above is as follows: you have to be on the spot at the right time, i.e., during the blue hour and not the whole night. So, in my case, I was lucky because it wasn’t planned.
You need a tripod and an extension cable. There are two reasons to avoid long exposures: firstly, the moon is a moving object. The longer the exposure, the more the disk moves. You end up with an oval rather than a round moon. A long exposure also picks up more light, and the moon’s disk turns completely white.
Compromises become necessary. Trying to get a perfect moon and foreground at exactly the right brightness is quite a challenge. By the time every attempt has been made to achieve a flawless result, the moon is already too high in the sky. We have to act quickly.
We’re advised to lower the ISO to 200, but if I do that, I’m increasing the exposure time and introducing too much light into the camera. Instead, I use a higher ISO to reduce exposure, and use all the camera functions likely to reduce the amount of light entering the camera: higher shutter speed, if necessary, strong negative exposure compensation, and so on.
By not overdoing the settings and using RAW files, there’s still enough flexibility to bring out the foreground, in this case the houses lining Matane’s beaches and the surrounding lights.
In short, shoot during the blue hour, act quickly, accept compromises, limit exposure time in every way possible and use RAW files to facilitate post-production work.
