Just received my Kickstarter dry plate holder and I'm excited to get out and start shooting the standard ASA 2 J Lane Dry Plates. However, being that I live in the desert southwest where I typically photograph desert scenes with lots of saguaros I'm thinking my usual spot metering techniques (used with film) may not be accurate due to all the green around; especially a saguaro itself which is, many times, the subject of my shot. So, I'm thinking that an incident reading may be more useful? How do all you dry plate shooters meter? Do you concern yourself with vegetation?

Thanks!
