Often, rain in the Pacific Northwest is a drizzle, rather than a downpour. You still need protection, of course.
Yes. We conduct workshops in Olympic National Park with
Julian Calverley who
prefers this sort of weather environment. Invariably, it is more of a constant drizzle. Often there is a combination of umbrellas and (more often) various camera tarp solutions (some DIY, some various manufacturers). They're a little bit like camera bags, it's hard to recommend any as the use case and preferences are so subjective and personal - my take is that whatever works best for someone is what works best for that person.
I don't personally shoot in the rain enough to have formulated a solution, but if I did, I would probably break out my wife's sewing machine, and having been on my best behavior (as always), plead with her to take some weather proof tarp material and sew some snap grommets into it after taking a few measurements with my camera kit.
