Photographers are also open to alternative domains. Our company had to change its name early in its existence. When we were explaining it to some photographers we work with, they were surprised that we didn't go with .co or .photography (shudder).

.com is simple and guaranteed to work. By that I mean both with humans (who just assume '.com' is the thing that goes in the location bar) and with computers (Interac e-transfers, a way of moving money in Canada by sending to an email address, don't work with .photography domains).
