Thanks everyone for the tips.  I did my best with what I had - a G  
filter and some intuition.  Worked in the past...  We'll see when I  
finish developing them.

By the way, Egypt in late June gets my vote for being the most hostile  
warm-weather locale for desert and urban photography.  120 degrees F  
down in Luxor at 11 am, no shade.  Like a freaking blast furnace!  Now  
I know why they always list the top end of the temp range as 140 F for  
electronics.  I saw some weird stuff.
