However, the "photo shoot workflow" is not the easiest to handle. One difficulty lies in the task of communicating to the photographer exactly what kind of photo one wants. So what can we do here? Our first workflow sample in our "photo shoot" series will be for a website design company.
By the way, if the request is for a "photo of Kyoto University's main gate (cell phone photo acceptable)," then someone who happens to be visiting Kyoto University that day can quickly accept the task and take it on his/her way to (presumably) more important business.
But if the task is to take "photos of company A's entrance (about 10)" you'll have to use a different approach. Assuming this is for company A's website, which you are being commissioned to design, these are pretty important photos. Once the photos are ready you can have other photographers (or other employees who like photography) comment on the finish. (Good feedback should be shared.)
P.S.
We expect more companies to start using Google Apps Picasa Web Albums this year. For Google Apps integrated workflows check out Questetra BPM Suite. This application allows not only SSO login with your Apps account, but also exporting workflow log data to Google Docs, adding task deadlines to Google Calendar, starting workflows with Google Spreadsheets forms, and much more.
