Hi Steve!
Is it possible in theory to use something like Sekonic c-800/c-7000 as probe-matching spectrometer for i1D3-like probe?
They are relatively cheap, in comparison to other spectros, and many DPs already have them in their toolbox or have easy access to them on set.
Those spectrometers have non-removable diffusors, and obviously calibrated for incident light measurement, but they are still spectrometers, and they still can output approximated spectral distribution in 1nm resolution, and they can measure x,y.
Some specs:
Spectral Bandwidth: Approx. 11nm (half bandwidth)
Range: 380nm to 780nm
Accuracy x,y: 0.003 (Standard Illuminant A, 800lx)
Repeatability x,y: 0.001 (500 to 200,000lx), 0.002 (100 to 499lx)
Will this accuracy be sufficient enough for FCVM/FCMM? Will non-removable diffusor affect measurements and applicability? |
