Narrative:

During a photo flight; the #2 and #1 aircraft brushed against each other. The #2 aircraft had a wingtip mission pod and the rear fairing of the pod was dented when it impacted the #1 aircraft's wingtip. Damage was minor. Both pilots were experienced formation pilots and in trying to take a picture of #2 and #3 aircraft without the wing blocking the picture the element was flying more forward than normal. The cause was probably due to an attempt to get a photo from a platform that was less than optimal for this purpose and #2 losing sufficient visual references to perceive the proximity to #1's aircraft. Both airplanes landed uneventfully.
