Any tips to help deal with this and make my photos better/sharper? I was at a concert recently and we were only allowed one song. The entire song there was this weird smoke/haze/fog from the fog machine and it was hanging around head height. Lots of photos are super sharp where there is no fog but anything in the fog is soft. I do not think its my gear as I got great shots of the opening bands without this fog. What could/should I have done different? Thanks.
