Hi CSers,
while there are numerous information on the net, Stobists, Lighting Essentials, Photonotes, etc giving extensive information about off shoe manual flash, I still can't quite figure out the "correct" or rather appropriate technique. Would appreciate constructive only comments, thanks.
To make it as clear as possible, I know the GN conversion rule, sunny 16 rule, light fall off, inverse sq laws, etc. I just need to understand the appropriate work flow and a little insight on the power ratio VS aperture and distance in manipulating the flash.
My main doubts are
1. Do I use the aperture (FLASH) and distance OR do I use the power ratio to manipulate the strength of the flash?
2. Do I set the power ratio at the mid point first (1/8) and then increase and decrease like FEC?
Please advise which option is correct?
(Option A)
1. Meter the ambience off the CAMERA (not exceeding the X sync)
2. Input the exact SAME settings (F stop, ISO) metered off the CAMERA into the FLASH,
3. Do the GN conversion and place the flash at the corresponding distance.
4. Adjust the flash by manipulating the F stop, ISO on the FLASH to get the desired effect.
(Option B)
1. Meter the ambience off the CAMERA (not exceeding the X sync)
2. Input the exact SAME settings (F stop, ISO) metered off the CAMERA into the FLASH,
3. Adjust the power ratio (1/1, 1/2, 1/4, etc) to get the desired effect.
(Option C)
1. Set the CAMERA to the highest sync speed.
2. Work downwards from the X sync until I get the desired shutter and aperture.
3. Input the exact SAME settings (F stop, ISO) metered off the CAMERA into the FLASH,
4. Do the GN conversion and place the flash at the corresponding distance.
5. Adjust the flash by manipulating the F stop, ISO on the FLASH to get the desired effect.
(Option D)
1. Set the CAMERA to the highest sync speed.
2. Work downwards from the X sync until I get the desired shutter and aperture.
3. Input the exact SAME settings (F stop, ISO) metered off the CAMERA into the FLASH,
4. Adjust the power ratio (1/1, 1/2, 1/4, etc) to get the desired effect.
(Option E)
1. Set the CAMERA to the highest sync speed.
2. Work downwards from the X sync until I get the desired shutter and aperture.
3. Set the flash at the middle power ratio (1/8, etc).
4. Input the exact SAME settings (F stop, ISO) metered off the CAMERA into the FLASH,
5. Adjust the power ratio either up or down to get the desired effect.
Thank you
