"Effects of using the plastic color filters on an SB910? "


Jackson, US
          

The orange and green plastic filters (tungsten and flourescent)seem fairly thick compared to a CTO gel. Is there a reference table to know how much light is lost using them? Are they the same as the old gels?

I haven't seen anything on transmission loss, but I would not think it would be materially different from the old gels. The thickness is no different from the gel retainers, as they are in essence colored retainers.

Try taking a light meter reading through an old retainer and gel versus the new filters. That should indicate any loss.

Scott,
It was dark last night when I posted the question. Today, I held a plastic orange filter in a window alongside one of the clear holders with a full cut orange. I can't see any difference in the two.

Thanks for the direction.

You're welcome Mike. Now you have me curious. I might compare the two by taking an incident meter reading with my Gossen LunaPro. The incident sphere is so small that I think it would not be materially affected by side lighting.

Scott,
If you actually do the experiment, please post the results here. When I held one of the plactic filters up, it just looked so much more dense than what remembered of a full cut orange gel. Side by side, they were very close when against my front window.

Does not the SB910 em mitt pre flashes to determine the correct exposure, so placing a filter cover over the flash output no mater what colour or thickness should make no difference at all. So if there is a light transmission loss using the supplied hard filters the the reflected light from the subject will be taken in to account and will give the correct exposure.

no1yak,
I was shooting in manual mode with manual also set in the strobes. I was questioning whether I needed to manually adjust a bit more for the hard plastic filters, but they appear to be similar in density.

The other question I didn't ask would have been how much light is lost when you put a "full" CTO gel over a strobe?

Sorry but you didn't say how you were using the flash. So I assumed that you were using iTTL - my mistake. By the way if you read my signature the name is Pete.
