Hi, I want to get a comprehensive set of ND's and Grad ND's (Hard and Soft) to use when I play with my camera in landscape situations, I have the Lee medium wide angle filter holder which accepts two 4x4 2mm's. I was looking around and I am interested in Lee's resin filters, since it doesn't seem they make 2mm thick glass filters...thanks,
Hi Brian,
I don't know how meticulous you are in your work, but if I'm not mistaken you do have the equipment quality that derseves like optical components. Depending on the density of the ND's you need, I'd certainly go for the
Lee ProGlass ND ones.
The problem with resin ones, besides that they can scratch easier, is that the dyes used are relatively transparent to IR, and despite filtering you digital back (unlike film) is still somewhat sensitive to IR. So as you increase the density of the filter, the light loses some spectral balance, and IR starts affecting all channels of the sensor (because the Bayer CFA is also transparent to IR). The metallic coating of the ProGlass series reaches from UV to IR, so colors stay much better intact.
Personally I'm not fond of grads, their use is quickly spotted by the linear division which only works with straight horizons. For most subject matter there are much better solutions available to manage high contrast situations by using bracketed exposures.
Cheers,
Bart
