I use it for both - I have two brands: and wedding videography company and a real estate photography company. I don't think I would use ShootQ if I only had the real estate business. It's too tedious a booking process when you're talking about more then 1 a week (of course, I could be doing it wrong...). I can't live without it for weddings though!

I have multiple brands covering several genres as well. We also use a secondary gallery sales system for some of our content for clients, video wise primarily, to sell clips and show videos ect. 

I left ShootQ a while back and after using others I came back to it. If you think outside of the box, not what you want to do, but what you need to accomplish, then it will be your best friend.
