"TTL-BL and Tilt Flash Head w/ White Card"


Los Angeles, US
          

Am I correct that I do not lose TTL-BL when shooting with the head pointed 45 degrees and the white card pulled out? I tried it and was pleased with the result. Then again, TTL-BL with the flash head pointed directly was nice too but only with the diffuser attached.

I also applied -1.7 flash comp.

Hi Mel,

Yes.
You are correct.
The orientation of the flash head doesn't change the flash mode.

Best Regards,
Marty

Afaik,you are correct. I use my SB 600 regularly with a large bounce card made from a cut-off window blind, or a pocket bouncer, which loses about 1-1 1/2 stops of light, but the BL feature seems to work fine.

Using the built-in bounce card automatically switches the zoom head angle on my 600 to 14 degrees, which also lowers the ultimate range of the flash.

My favorite use is to deploy the built-in card about 1 inch, just before it flops to cover the flash head, which lets those raging photons bounce against the ceiling, but provides a bit of fill for the shadows caused by the bounce.

I don't regularly use the compensation...how does that work for you?

I use flash comp so that the fill light is subtle. Sometimes the people I shoot have oily skin and so a little fill is usually enough to not give a hot spot on the forehead.

Hi,
I`m just curious here to know when you speak of using the built in bounce card on your SB600 are you not talking about the wide angle diffuser which goes to 14 degrees automatically or has the 600 got a white bounce card as well.

Actually, what I should have said is, I use the partially-deployed flash diffuser as a small bounce card (sort of) which provides a smidge of fill. That automatically defaults the flash head angle to 14 degrees, which also softens the light somewhat A bigger card works some better, tho.

sorry for the confusion.

TTL-BL works best if you do not tilt the head.

The reason for this is that when the flash head is pointed directly at the subject, distance to the subject (as reported by the D lens) is used as the primary input to the BL calculations to determine the correct flash power.

If you tilt the head (or use a non-D lens), the system reverts to the monitor preflash to determine the correct flash power, but that doesn't work very well when in bright daylight. Of course, TTL-BL should only be used in bright ambient conditions and the camera meter must be centered. Most pros shoot TTL-BL fill shots using camera P mode to be sure the meter is always centered.

Most of the time, you don't have to worry about diffusing the light when using TTL-BL mode, because you are only adding a small amount of fill, and diffusing doesn't change the image noticeably.
