"SB600, Gary Fong Lightsphere, vertical"


Toronto, CA
          

When I turn my camera vertical, I do it by rotating counter-clockwise so the right side of the camera is up.

If I then rotate the flash head so the lightsphere points up, it is right over the SB600 sensor. I PRESUME this is why when I do this I get under-exposed photos.

If I shade the sensor the problem goes away ...

So ...

  • is may analysis correct?
  • anyone have a neat way to deal with it? (other than rotating clockwise -- I prefer to hang the camera from my right hand)

You can mount you flash on a flash bracket (I use the RRS Wedding bracket) so the flash always says over your camera. This also eliminates the problem of having the flash on the left and getting shadows on the right side of your subject.

Hi Dennis,

That is strange!

I assume you are in TTL flash mode?

Are you refurring to the light sensor window on the side of the SB-600?

That sensor is used to detect commands from the Master when the SB-600 is in Remote mode and should not affect the flash exposure at all when the SB-600 is in the cameras hotshoe.

Check the Ready light on the back of the Speedlight or in the viewfinder (lightning bolt symbol on the right side) after you capture an image. If it flashes, the SB-600 has fired at full power. Now check the image. If the image is under exposed, you will have to open the aperture and / or increase the ISO to get a correct exposure.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Of course its the command sensor! -- I KNEW that but forgot.

Its interesting that if I cover that sensor (but maybe I am interfering in some other way when I do that) -- anyway, if I DO cover it, the exposure is back to normal, as it is with the camera and sphere in the normal position.

I am going to play around some and try and narrow it down.

Yes -- perhaps its time I got a bracket -- I do a lot of candid stuff, home, office and church -- so just having the sphere on was simpler!

Thanks for the replies!

"Birthday is coming and my wife wants to know what to get me "

Tell her you want a SC-17 or SC-29 cord, the best investment for the flash you can make.

The SC cord will make the Fong 10 times more useful.

I'm trying to understand what you are saying.

Is your SB600 mounted in the hot shoe? If so, the command window on the SB600 is not used. The commands are sent to the SB600 through the hot shoe.

So covering the command window would not change the image. Something else must be going on here.

What modes are you using on the SB600 and camera?

Thanks all -- I THINK I have figured it out.

I wear glasses and wear them when shooting, I have the viewfinder adjusted for the glasses -- very nice.

With the lightsphere in the hotshoe and the camera horizontal, no problem.

With the camera vertical and the lightsphere rotated as suggested in the instructions that came with it, the sphere is quite close to the viewfinder and light gets in around my glasses.

If I put my hand between the lightsphere and the camera body it shades the viewfinder and keeps light from creeping in.

If I take off my glasses and put my eye tight the viewfinder the exposure is as expected.

I have had a problem with this for close to 2 years -- posting here forced me to look much more closely.

Not sure where I will take it from here -- but knowing, I can deal with it. And maybe I DO need to get the flash off the camera -- its just that doing candid's at our church, people already comment on the very large "thing" I carry around

Ahaa!! I knew there had to be something else going on here.

That's a new one I haven't heard before. Into the memory bank for future use.

Thanks for letting us know.

I never really believed the "sensor" thing -- it was just that in the heat of photographing randomly moving subjects, putting my finger over it worked -- it was just that my finger dragged my hand into a position to block the light.
