Ok so I have always wondered what exact equivalent my flashes were because I shoot really a mixed bag of flashes. I thought this would give me a rough estaminet on how to use my setup in the future.
My friend let me barrow his Polaris flash meter to test this and I am in an way excited with the results and in an way surprised. Note this was not a scientific exact setup.
This is not direct flash power or anything and no I did not test the different zoom settings because I was on my lunch brea and personally I don't care because I was doing it just for me in my real world setup.
In the real world I shoot my flashes normally into an bounce umbrella at like 5 - 6 feet. at 24mm zoom setting into an 43 inch convertible umbrella.
I tested at 100iso 1/250 normally I shoot anywhere from 100iso to 800 iso. I normally start at 400 iso but I wanted to get the fstops full power at 100iso and the max shutter speed. my camera goes to with strobes.
All were shot at full power.
There are a total of 9 ticks and I believe 3 ticks = 1/3 it looks like
Nikon SB-24: f5.6 and 1 tick
LumoPro LP160: f4.0 and 6 ticks
Canon 580EXII: f5.6 and 6 ticks
Yongnuo YN 568EX: f5.6 and 4 ticks
YN568EX+580EXII+SB24 on tri bracket: = f8.0 and 9 ticks
YN568EX+580EXII+SB24+ LP160 on quad bracket: = f11 and one tick
Large softbox direct...
AlenBee AB400 at full power: = f8.0 and 9 ticks.
This is what the quad setup looks like. For the tri bracket just remove the bar and put a flash in the middle.
What do you all think of the results of my tests?
