Altitude used to have photos up on their website, but the web guy cant be bothered at the moment, and management dont know how.
However they have piles of cds filled with pics in the office, and are generally happy to have pics taken....
but always ask first, as some event promotors dont allow photography, and Altitude dont have a say in that situation. So it depends on the event.
If you have taken photos at a club, it always pays to e-mail them a few of your images as thanks.
