ray: I think you need to start shooting more 120 format slide film around the beautiful areas you have. Heck, I could burn a few rolls just in one day without even leaving Island Bay or Lyall Bay

. South Island it'd be probably be 20-30 rolls over some amount of days no problem. I'm a fairly judicious shooter as well, perhaps you just need to get out and shoot more? Alternatively maybe it's because you've already seen and shot it all - hence lack of interesting subjects. Do you photograph people?
Nope, don't do much people. Ever I started reading into photography I enjoyed the likes of Galen Rowell etc. So unless I travel to the National Parks ie - the South Island. I have a few pro packs of 120 format but no camera yet still on 35mm.
I have been to Lyall Bay and Island Bay and have shot them. I was just at Titahi Bay in the weekened and shot 20 frames off my Kodak Gold 100. Was in Palmerston North too on the Saturday and shot 10 shots of Superia 100, was raining lol. Finihsing up my C41 you see .. Just a roll of Fuji 160 NS and a roll of ProC 160. I may leave my UC400 and ProH 400 for overseas when I see family there. No don't do much people, birthdays and Christmas goes thru and I don't take the camera out unless we have visitors. But they are not that into photo's anyway so it is generally just 2 or 3 frames sitting together on the sofa.
I've started doing some b/w for street photography. But the beaches here. B/c I am drawn to the likes of Galen Rowell with magenta skies we don't actually get much of that here. We get a very light pink hue but mostly it is just grey with maybe some yellow of the sun but it is not very strong so it needs to hit you at a certain angle as you face at it, and that is the most it gets. Post sunset the light becomes draws into a shadow and it just dulls away so we don't get any soft light hitting the sand / rocks either. Wellington is known to be windy and it's a big sea out there so there are like rocks and stuff ... So pretty much no reflections. No trees unless you want to see houses too or hill tops.
Been toying around with twiligh blue skies since the light isn't great here. Which is ok for the CBD. In the beaches they just get too far too dark for the foreground.
PS just a bit of what I have done ..

I am more selective with film even when I shoot it, at home, if it is not so great I do use digital. Even when it was digital, I did just to chase sunrise but it wasted a lot petrol. On a Saturday, I would drive out early morning to Oriental Parade or Island Bay and it was just dissapointing, many times I came home without taking a shot. Would be a lot easier if I was in the CBD or lived near the Bay, but I live north of Johnsonville thru the motorway.
