Hi guys I wanted to ask the advice of any photographers out there that have used one of those Mirror Balls to take spherical images that can be converted into HDRI images? (i'm guessing I would photograph initially in uncompressed RAW format?) I have so many beautiful (and historical) areas near me in the UK, I would love to have a try expanding my photographic skills. What is the correct name for the "Mirror Ball" devices? I can't seem to find them on Jessops (UK photographic chain), so is this specialist equipment, or am I just searching for the wrong thing? Yours hopefully! >8o)
