I have been trying to get lightning pics with my A2S the last week with moderate success. I shoot in almost pitch black conditions at night, in full manual, RAW format, ISO 100 and shutter speed set to 8 seconds. Then I just take continuous pics and hope a strike happens when the shutter is open. Problem is...lightning is overexposed. I'm thinking about using an ND 32 filter to tame the light down. Anybody have any ideas or advice. Included is an example of an overexposed lightning strike pic.
