Please note: the smaller versions are generated by Zenfolio in sRGB format but if you select the 'Download Original' option, you will get a just over 50% of originally shot sized version in Prophoto colour space. Please make sure that you view those files in a Prophoto-aware application and on a calibrated, wide-gamut monitor. Some files shot with polariser. All files developed from RAW in Lightroom 4 with Camera Standard as the camera calibration profile. I am still working on the best solution for colour calibration and management and will post more on this soon.
