Not photoshopped, but he's holding the snake very close to the camera which really screws with the depth you see in picture. There are lots of pictures out there of people holding snakes and all of them claim that they caught and killed the world largest _ _ _ _ _ _ snake.
This is an Eastern Diamondback, and those can get HUGE. I've seen several 6-7 footers before and spoke with the guy in Edisto Island SC who actually caught the largest one of them recorded (at least as of 2008). it was 8+ feet. I think this one is just another big EDB that looks much bigger because of the way the guy is presenting it
What's wrong with keeping snakes. I have experience with several types of snakes. I've owned mostly constrictors. Pythons in particular but have experience with Cobras, Mambas (both of which had venom removed), gaboon vipers, and rattle snakes.
