Appreciated Kevin Raber's kind words as he recounted on Luminous Landscape the last Silo City workshop. Seeing him with the 600mm lens made me smile and I knew he was going to be surprised when he saw I had brought only an iPhone to work with in the grain silos. You can view the work from the visits to Silo City here
Here Kevin demonstrates the proper way to use a 600mm lens- as an iPhone tripod!
One of the fun things we were working on during the workshop was the multiple exposure capabilities of the Hipstamatic app. It is a fun to use feature that takes a little testing to get the best results from. Kevin posted some really good examples of using the multiple exposures and demonstrated how good it can be when you nail it. I don't use the feature a lot but it does provide some nice alternatives.
