Estella Sneider showed me one of her recent shoots that she shot for Mauricio Umansky of the Umansky Group in Los Angeles/Beverly Hills.
I noticed that Estella's tour is built around Slideshow Pro Director which nicely handles the issue of universal access. That is, making sure your tour/gallery looks good on Flash and non-Flash platforms.
Many website galleries and tours these days haven't been updated to look good on iPads and iPhones. Some sites/tours have been updated to show something, but the fix is quick and dirty and doesn't look as good as it could. Estella's tour (believe the tours are done by the Umansky Group) demonstrates that there is no excuse for not having tours and galleries that look great on platforms that have Flash and on those that don't. It takes some HTML coding talent to brand Slideshow Pro Director slide shows but anyone can use them without branding.
Have you checked to see how your tours/galleries look on non-flash devices?
