Cambridge HDR with FX100

 I am still trying to decide if the in-camera HDR on the sony FX100 is worth using - it certainly does a good job on high contrast scenes but I am not convinced it is better than doing HDR from a single RAW file. Three separate exposure images recombined with HDR Pro would probably give better result but this is not an option when a tripod cannot be used as in Cambridge Colleges. The left-hand images are the best adjustments from a single image (jpeg), righthand are the HDR output from the camera. I need to do a raw image as well as the in-camera HDR.
