I thought of posting an image or two in the gallery but then realized I had a few questions etc. I got from Bostick&Sullivan some Sodium Chloroplatinate (Na2) about 10ml along with my normal order of some palladium #3 and an equal amount of FO. I wanted to try out the Na2 method of contrast control. It had been suggested by numerous people (and people that quite honestly know a whole lot more than I, so I heeded the advice) So I tried my hand at it last night. Also the last week here in Austin weve had an abnormal amount of fog for our area. So I went out a few days ago in the early part of the morning to explore taking some photos in the fog. Something I have little experience in. But I really enjoyed and have always wanted to try.

Dick Arentz site mentions it should be used in Addition to the total metal drop count (as in 33 FO drops, 33 Pd Drops, +the Na2 drops) while some others have mentioned that the Na2 Drops should be a substitute (33 FO drops, 30 Pd drops, +3 Na2 Drops) what if any is the advantage of either method and what are the methods and opinions of those who work with the Na2 contrast method. by the way I do quite like the results of it. noticeable nicer and smoother sky tones etc. (the fog shots ended up being a good way to test this out as I did some comparisons between the Na2 method and the traditional FO w/chlorate. also, would love anybodys thoughts opinions critiques on the images. ' thanks.
