I went out this morning with the Minolta loaded with HP5 and my OM2n loaded with AGFA 200 Vista, set up on one of my favorite sites but it was so foggy I could not see 50 ft. I had decided to last it out till the fog lifted. I was using a 50 1.8 and 1.7 so I had light, just could not see across this water area to the tree line. I swear this fog lifted so quickly it was completely gone in 5 min. and was now direct sun with not a cloud in the sky. I went home and cleaned and organized my computer and photography room to make me feel like I had accomplished something Lol.
