Hi Panyakit. All of my neutral density gradient filters (NDG) are of the Lee brand except for one, which is a reverse NDG by Daryl Benson/Singh-Ray. All of these are rather pricey, especially the Benson filter. They are also of quite good quality and well made. Since I shoot mostly medium format 6x7 and the filter sizes are somewhat large, these NDG filters are all 4x6 inches.
I also have some Tiffen filters for special effects, such as a North-Star cross-screen, some diffusers, and an opaque IR filter. The cross screen is glass and was very expensive. The quality of the Tiffen filters are also quite good.
I think that far more reasonably priced alternatives exist in the HiTech brand. From what I have seen over the years the results are similar.
P.S. Of course someone such as you are more than welcome to visit my Gallery & Portfolio of my most humble Medium Format images here to comment on as you wish while I am still shooting with that 'Beloved Fuji 645' which I will go to my Grave with ... :))
A most 'Professional Photographer' who I have known for so long now! Glad to have you back and still shooting with that 'Very Heavy Artillery of a Diehard Camera' @ F22 also in a 'Medium/Large Format Medium'. FANTASTIC image all the way through, but I would have preferred a thin white inner border to offset the black outer 'Bold Border' if you know what I mean ... Right?
Hope you are healthy Walter and please do not stay away for so long ...
