Ok, I have to admit I am a dyed in the wool ZS user. But being bored the other day I picked my second edition of the BTZS book and started reading through it. So I got to the section of how to use the incident meter and decided to give it a try. I was amazed at how simple it was to arrive at an exposure. So, I understand why add "5" to the SBR but in the book I read the charts that say SBR=4....how come? I mean if I take a light reading and a shadow reading subtract them and then I add 5, the minimum SBR I can get is 5! where did this SBR of 4 comes from?
So is now confession time, I always thought the BTZS made a simple thing more difficult than it should, but now that I have tried it I am seeing I might have to eat some crow and learn how to do this. Back in the second edition one had to draw the curves etc, and I was adamant about not spending all this time drawing curves, but now with the plotter etc. Things are a lot easier and the testing should not be any harder than the normal SZ. As a matter of fact doing it with step wedges is a lot easier and less wasteful.
So Phil if you explain to me where that SBR of 4 comes from I will be glad to mail you some of the crow feathers left over..
