I usually take an iPhone picture before I shoot with my Nikon D4S or D800 so I can organize every detail and be happy with the final composition.
Sometimes the first shot with my iPhone is so nice that it's really hard to copy with my camera because the rider was in the correct position, the light was great etc. When I find a spot like this it's easy to play with the longboarders.
I used my iPhone 6 and I just retouched the saturation a little during the editing, nothing else. Lucky day!
