A little more than a week ago, there was an earlier thread on Arthur Morris' Pocket Field Guide to Evaluative Metering Systems. Quite a few people recommended it. I went to Artie's web site and saw an images of the guide. I really liked those examples and decided to order one. I sent him a check and it only took a one-week around trip (California to Florida and back) for the guide to arrive. Unfortunately, the earlier thread had drifted into a flame war and was removed. So I am posting my own review here. Obviously you are entitled to your opinions on everything, but please post constructive follow ups only (it can be positive, neutral or negative). Flames will be deleted. On one side of the card, there is a short description of tonality, subject tonality vs. background tonality, sun in or out, and size of the subject, etc. On the other side of the card there are 60 samll images on different situations: dark vs. white birds, dark vs. light (sky vs. water vs. tree) backgrounds, etc. etc., and the amount of exposure compensation Artie recommends under those conditions. The focus is clearly on bird photography. He also correctly points out that these values are approximates; it varies a bit depending on one's personal preference, film type, etc. Exposure is a very basic yet difficult issue in nature photography. I think this Guide would be very helpful for beginners to intermediate nature photographers as it explains the basics with a lot of good examples. In my case, I understand these issues quite well already. In difficult lighting conditions, I prefer to use a spot-meter reading on the subject and compensate from there, as that method has worked very well for me over the years. However, in some situations that it is hard to use a spot meter, such as birds in flight, Artie's method seems to be easier to apply. In the earlier thread, several Canon EOS users and some Nikon F4 users have indicated that Artie's "exposure compensation over evaluative (matrix) metering" system works very well for them. However, my concern is that the more sophisticated RGB matrix meters are supposed to be able to automatically compensate in some (but clearly not all) difficult lighting conditions. If one applies Artie's system, there is the risk of double (or over) compensation. If one uses one of those cameras, I would start with a center-weighted meter reading and then apply Artie's system; I think it is safer that way. In my case, I don't think I'll need to change what has worked for me for a long time, but Artie's guide is useful to verify exposure, and I may incorporate it in some situations. Arthur Morris is clearly one of the best bird photographer today, but he also seems to be a very focused person. His Field Guide is heavily geared towards bird photography. For those who are also into landscape photography, there is no discussion on graduated neutral-density filters, for example. There is a short description of Fuji slide films. Fuji slide films happen to be my choice of films too, but my observation is that I simply don't see Artie talk about his experience with other brands of film, other brands of cameras, and other camera formats, other subjects (besides birds) etc. Again, just my observation, this is not a criticism.
