Within the past few months we released ass kicking new versions of Exposure, our film simulator, and Bokeh, our lens simulator. These are our first two products that are 64-bit on both Mac and Windows in order to work great with Photoshop CS5. Our other products will get free 64-bit updates very soon. There will definitely be a blog post when those are ready!

Below are the intro videos, but we have plenty more slick tutorial videos, example images for Exposure and Bokeh, or you can try them yourself for free.
