I don't know. I guess my mindset is different.
I approach every shoot, no matter how small, as if it were on assignment for Architectural Digest. But I'm a perfectionist and I feel very grateful for every chance I get to shoot for money.
Every shoot gets all the attention to detail as every other, even if I'm just called out to shoot one photo in broad daylight.
That way, when a client comes along who is ready to throw down the big bucks (and there is at least one in EVERY market) I'm ready and I won't disappoint. Ask yourself if you're working for that person. It might not be a realtor. There are architects, architectural product corporations, magazines, hotels, ad agencies and resorts in every market.
Treat every RE shoot as if it were a shoot for them. So when opportunity knocks, you're ready. And don't say it's a matter of not having enough time - I can light a space w/ my current six light setup and get 8-10 photos in 90 minutes if I don't dick around and the house is ready.
