I did something similar last night. We were doing some astro shots even though it was 100% cloudy the lens picked up a lot of stars using 30 and 8 second exposures. I was surprised we got anything.
I thought that I had uploaded them to the computer and formatted the sd card but the only photo that got copied was that sunset i posted earlier?
How weird? It happens lol
I see what you mean about the curved doors. They are echoed on the curved edges of the building. Nice colour btw.
Well sorry it happenned to you but it does make me feel a little better that I am not the only one making this mistake, this was weird of the HDR image sit only imported the +2 exposure shots in most case, never had that happen before
I am running a second file recovery tool now, the first one had no success, but this one seems to be finding some, fingers crossed I can recover them
Good luck.
