umm saroj,
I dunno much about HDR photography but what I wanted to ask was whether you used chrome ball to capture these and then re-edited them later with software like HDR-shop or something or you stitched different photographs captured via special camera rig where you place the camera on a tripod and rotate it at some rotation angle to capture whole 360 degrees ?
I asked about resolution because I think HDR images are captured with different exposures, so unless you have a better resolution image it's hard to get different light intensity values at different exposures.
There is much variation of HDRI capturing on-line, so I asked about your method and I am interested in knowing more about it.
Once again I don't know much about HDR photography so please let me know if this sounds okay or not ?
Thanks,
Shashi Kant
