In reply to the camera question, my pics were all iphone (cos it’s convenient and in my pocket anyway) apart from the one of the guy leaning on his bike which is 120 slide film cross processed shot in one of these:

unpredictable, sometimes disasterous, sometimes brilliant!
i have a pentax optio which is a pretty sturdy and small waterproof compact which takes decent point and shoot shots:
you can get some pretty cool stills with the older non hd go-pro camera’s which i’d imagine are available pretty cheaply now:
apologies for hijacking with water pics but it illustrates the point!
Incidentally, i got given a waterproof iphone case to review for surfing with a couple of months ago, too big to keep in a pocket probably but good enough to cope with taking pictures/ checking strava in a downpour!
