Are you looking for Photoshop Extensions? I'm pleased to announce that CS Extensions, a brand new website entirely dedicated to Creative Suite products targeted to Photographers and Retouchers, is finally online (a project that kept me quite busy in the last two months).
Phase One digital back raw files are not fully supported by Adobe Camera Raw (all versions) because the sensor calibration data embedded in the .IIQ files is not interpreted. This leads to a so-called paneling "bug", affecting the sensor's response uniformity - I came up with a workaround.
