I have a pretty long background in photography and I agree that this photo is completely plausible.

The ambient light cause the images of the trees to be registered first; the animal jumps and the flash trips and captures the image of the deer frozen in midair. The timer on the camera would naturally have a very slight delay before causing the flash to trip...thus the brighter light shining through the trees would register sharp enough to be registered first with the overlay of the animal captured by the flash. The flash does NOT fire as the precise moment that the lens opens to capture the image. It is essentially physically impossible.

As to the blood...try those Rage broadheads and see for yourself. They lay that animal wide open instantly. By the time it coiled and jumped, that much blood could easily be beginning to exit near the entrance wound because of the pressure created on the lung area from the deer recoiling to jump...and it has to recoil first to jump.

This era of game trail cameras is a new era. We'll see more amazing photos of shots and I'm sure we'll have people who simply can't believe that such things could happen. If you've hunted and fished long enough, you should know that the truth is a whole heck of a lot more unbelievable than anything you could make up.
