Hi Ray

Of the three that I tested the Delta 400 had the best results. But that is not 
a great indication as one of the others was almost totally red blind and the 
other is only extended red sensitive under very bright conditions.
I'll re-test the Delta 400 with my LED box this week. My original tests 
indicated that if pushed one stop the results were passable.
I'll try it on the LED box at ISO400 both plain and hypered.
If you should try it and you use HC-110 watch out for the conflicting Ilford 
data. One sheet says 5 minutes at 68f and another says 7 1/2 minutes at 68f. 7 
1/2 minutes is the correct developing time. 
This skewed some of my testing along with large variations in sky conditions 
when I first tried to evaluate the film. Hence the LED box was knocked 
together, it allows me to filter out the really bad ones before I star test 
them.

Clear skies and good health
