Natura 1600 by Fuji is a true ISO 1600 film with fine grain for this speed.  I did some google-ing and found that some folks shoot it at 1250 but for my first two rolls I shot it at 1600.  It is only available in Japan so to get it here makes the film a little pricey.  And of course like you’re not supposed to, I shot it first time for my nephew’s wedding - mind you I was not the principle photographer , just a guest. 

Outside shots in full sun came out amazing.  These photos were taken at the USS Grayling ( SS 209) memorial at the Sloan’s Lake Park
