>>3893977>Should I set my ISO higher/add a stop or two when using the Ektar in the event of overcast?No, shoot at box speed. You won't need a tripod in overcast even with 100iso except in the forest. Overcast weather is the best possible conditions for shooting in PNW forests so enjoy it.
Personally, I would hesitate with Ektar as it tends to go quite blue/cyan in overcast...but if that's all you have just shoot it you can always colour correct in post.
Just take photos and don't stress too much anon, enjoy the trip. I lived in the PNW for a long time and Hoh is one of the places I never made it to.
