What the heck is HDR and why do you care? 
If you require architectural photography, whether interiors or exteriors, you need to know about HDR. High Dynamic Range photography combines several captures, usually 3 to 7, of an identical room or building made at different exposures. Special software (Not Photoshop!) combines them to brighten the darkest parts and darken the brightest to deliver a stunning, snappy, highly-saturated final image. The above is a good example, which also includes perspective correction.
This summer, the University of Colorado Hospital marketing and communications team commissioned a series of photographs in and around their new construction that would visually convey their core principals. For a building this pretty, I knew they had to be HDR. We used a 30-foot rented construction lift to get above distractions like trees and signage, and made two angles of Pavilion 2 in one evening.
And it works wonders on interiors, too.
Why is this important? Part of the job of the photographer is to, when appropriate, capture what the casual viewer sees. A cool glass building on a great night, or a lavish penthouse interior, really look this way. The camera just needs to be talked into it.
