I will be in Texas for it with my Sony RX10 III
I have been reading various sites about doing photos but the number 1 thing just seems to be practice, using the moon is a good idea of settings needed for totality apparently. I am a little nervous about it as I am not as familiar with the Sony as I was with my Canon 650D. The Sony also has a lot more electric rather than manual adjustment so it's easy to loose settings. Bracketing is something else suggested but something I haven't really used much. I have a remote shutter and will take my smaller tripod to try and ensure sharper images.
I bought a ND100000 filter (16.6 Stops) as I plan on taking photos up to and after totality, of course you need to take the filter off for totallity photos. My main aim is to just spend as little time as possible with the Camera it's something I really want to experience but also would really like to get a good photo.
