Hi
A quick question - can a Cooled/Spectrum enhanced 40D DSLR be used for daytime photography too?
Thankyou
Doug Robertson
Hello Doug Robertson,
Thanks for your inquiry.
Yes, you can use your camera for daytime photography. But you can find the red emphasized color tone.
If you use our CP-1 filter you can correct the color tone to original Canon color.

As if the huge white 300mm L lens wasn't conspicuous enough! Now I can wander around my son's soccer games with a bloomin' great Excooler hanging off the left side of the DSLR too - eyecatching!!!
