This last trip to Thai I used a small hand held meter to meter my Khon Thai shots. I will have to go to a spot meter next trip and place the face of the subject on about zone V. I thought that with a ASA rating of 100 for Tri-x and the small hand meter I could do the job but found many of my negs (especially on the faces) were under exposed. Next trip I will take a spot meter to do some quick metering before I shoot to assure myself enough negative density in the faces of my subjects.
Looking to get a Pentax digital spotmeter on Ebay cheap.
