Woah, VeeP, are you serious? Dude... It's only 8", if you think you have to use Photoshop to get that long, then I kinda feel sorry for you...
It was a bit of a nightmare staying hard and working the 10 second delay and getting in position, but I can assure you there's no Photoshop involved!
I would be flattered, except you said a 'poor' job, haha...
