"The sensor chips on the gels for SB900 and SB910 strobes"


Jackson, US
          

The SB900s and the old style colored gels and the SB900 units have two of the new hard plastic gels. Both kinds have the little smart chips on them that let the strobe know what kind of gel is mounted and apparently that information is passed back through to the camera. At least in Auto White Balance, I understand the camera will be making compensations for the filters.

Is that a good thing? Normally, I shoot in Manual White balance so I control what is going on. Will Manual bypass the adjustments that might have been made automatically from the chip data?

I watched some Joe McNally tutorial videos about the SB900 on Kelby Training. He explained the chips, but never clearly indicated whether he liked the feature. Seemed like he was holding back some comments.

Do the people here use this feature or tape over the chips?

Thanks in advance,

I found this page on Nikon's site that helped explain this feature.

Looks like the sensors are only affecting the exposure when the strobe is actually on the hot shoe and not in some sort of remote mode.

The control tags on the gels are not electrical chips, just a decal or ink spot that blocks the light to a sensor. These sensors generate a binary coded value that identifies the filter. And this only applies to the on camera flash. There is a pinned post about the CLS Pre-flash sequence and the SB-900/910 did not change this part of the CLS system. There was a post that decoded the markers.

"Homemade filters for SB-900" discusses how to code your own filters.

I do not think one would want the remotes to control the white balance as the remotes are more about highlighting can not being the main exposure of the image. Also by not having the remote controlling the camera one has more artistic control over the lighting. You can have splashes of color on the background or as a highlight.
