Help With SB600

[Monkey]

Im sure i didnt get this problem with my D50 or D80, but when i use my SB600 on the top of my D200, in normal position is fine and i can go from -3.0 to +3.0 and see a difference right through the compensaion range.

If i bounce it, i can underexpose, but once i pass 0.0, it appears to make no difference at all.

Has anyone come accross this, i would have thought that even with bounce, +3.0 would really overexpose quite alot???

 

[cherryrig]

As the flash is pointing upawards and bouncing back the light it is very hard to tell what the difference is unless you start powering the flash up or down. Changin -0.0+ doesn't really make much difference to be fair

i may have mis explained it. on bounce moving from -3.0 to 0.0 in 1 stop inc you see the difference, but from 0.00 to +3.0 there is no change

not if by using bounce you are going beyond the effective distance.
have you tried increasing the ISO by a large margin ?? say iso 1600 can you then over expose?.

 

[Monkey]

iso 1600 does over expose yeah

i just cant understand why i seemed to have more usable power from the d50

 

[theory]

have you checked what your flash sync speed is set to? and shutter speed?

 

[Flash In The Pan]

For the record D50 max sync is 1/500, the D80 and D200 are 1/250 max

 

[chuckles]

What compensation button are you using?

There is one near the shutter release which controls overall exposure compensation. There is another near the lens release button which only controls the flash output relative to the overall exposure (I think ).
