Same here. When I suggested pix/video I then said "maybe not" and then my comment about our human perspective.
I understand where you're coming from as I believe many keepers intentionally stress their cham (especially males) to show "their colors" and other behavior. I know you were only looking out for the cham's welfare

>>I can see how you misunderstood my post... I am well aware that this was stressing him. Hense my postmessage stating that I have since been careful to make sure the fan is off. But as any human, I know I'm bound to forget one day and since I have both digial and video cameras always on hand, I'd get a shot. I'm not so heartless as to subject my chameleon to stress on purpose. I never force him to come out, he come willingly and when he does, I stay very near his cage in case he wants back in at any moment. I'm sorry I gave the impression that I would stress him on purpose.
