Lovely stuff Ian. Were those taken with a high DR setting?
I did not use the HDR setting on the camera (have not done so yet), just shot in normal AP at between f4 - f8 at 200ISO. I do convert to B&W using SFX Pro2 and used the HDR setting for that conversion then added some structure.
For landscape/street, the X100 is now my camera of choice and I am sure will remain so - the X100 manages to capture a beautiful array of tones and since updating firmware to 1.13 I am sure the AF is considerably better.
I am due to go on a trip next month so plan on taking the X100 for street and the GX1 to use with the 45-175 and 20mm and as a back up!
