Here are some of the pictures we took for the Pin Flower Fairies poster. All have their merits, but we had to go with one that would work well with the title and credits.
We used the same camera to take the pictures as did to shoot the movie, an Olympus OM-D E-M1 Mark II with a 25mm f/1.2 lens.
We don't do much in the way of editing; just cropping and small adjustments to exposure an colour saturation.
One thing to note is that these were not taken at the same park we filmed in. We actually forgot to take pictures while we were there and had to stop at a different park on the way to the next location.
