FYI, i just did a test to see how my flash and pocket wizards go at 800sec.
i did 4 tests, sorry i was lazy with the exposure- but it was same on each test, 60th sec through to 800th. look at the difference between 500th and 800th on all the tests. ,
1-profoto 7b full power/ pocketwizard plus/ h1/p25
2-profoto 7b full power/ sync cord/ h1/p25
3-profoto 7b half power/ pocketwizard plus/ h1/p25
4-profoto 7b low power/ sync cords/ h1/p25 (i balls up the exposure, but you can see the result)
it looks as if i lose about stop at 800 no matter what combination, weather i use pocket wizards, sync cords, even with the flash at low power (for quick duration).
why is that? is it something i will just have to live with?
