Re: [OM] T32 for Macro--question

[Chuck Norcutt]

The principal problem here is OM flash with no OM body to control it.  I 
pursued this for Mike because I truly don't understand what's going on 
with the auto mode.  As I showed, lowering the ISO does cause the flash 
to increase its output.  I have to do it again to convince myself but, 
after doing this experiment, I tried a few quick shots after increasing 
the ISO hoping that would reduce the flash output such as you'd want for 
fill flash.  It was really quick so maybe I made an error but two shots 
with +1 and +2 stop increases in ISO appeared not to change the exposure 
one bit.  Color me mystified.  Next time I'll drag out the flash meter 
so I can measure the output rather than guessing at it.
