Does anyone know if there are any other manufacturers of a reverse ND grad than Singh-Ray? They are just too much of an investment for me at the moment.
Never seen that before.
surely this is just ridiculous... a filter cant actually increase the amount of light hitting the lens can it? Looks just like an upside-down ND Grad to me.
A seemingly simple solution would be to physically turn the filter upside down and position the top edge of the filter over your lens parallel with the horizon. Unfortunately, regardless of lens or aperture used, the filter's physical edge bends, reflects or distorts the incoming light. This leaves an unwelcome bard of light or distortion on the image.
The solution to this problem came in a phone call to Bob Singh. With an explanation of the problem and a little experimentation we developed some filters, that, like all graduated filters, were clear at the bottom, however at their horizontal middle started very abruptly with either a 1, 2 or 3 stops of neutral density and then graduate to 1 or 2 stops towards the top of the filter. These three reverse graduated filters have solved many tough lighting situations.
Ah, I get it now. I am glad I didn't say, can't you just turn the filter upside down now.
For what this does I wouldn't say the name reverse ND Grad is particularly appropriate or fitting but there you go.

Now on a serious note, could you use two soft weak ND Grads. Have the tops of them overlapping to an amount.
This could give you, from the bottom,
clear , clear , clear, 5, 10, 20, 25, 20, 20, 10, 5, 5, clear
(numbers are % ND roughly). IT would take two slots up on whatever holder you are using, but is possibly cheaper than a single singh?
They could make it a bit longer and have a clear bit at each end. Reverse and normal in one filter!
