I like the effect.

LOL....I wouldn't mess with anyone that has a face like that!

[quote=nascar27][quote=f8lee]This is what is generally called a variable ND filter, and yes, it is a pair of CPLs that you can twist relative to each other to achieve nore or less darkening. I've had the Singh-Ray for years, and while it works well when it works, you need to be aware of a potential issue - what is called a "maltese cross" effect. This is where an X shaped shadow appears in the image.

I know from experience that this effect depends on the specific digital camera and lens being used (it never happens with film cameras). I believe it has to do with the constructive and destructive interference effect that can become visible on a particular sensor depending on the photosite sizes and spacing. In my case, the filter worked extremely well with a Nikon D600 but later I found the problem (which led me to learning about it) on my Fuji X-T1 and later, X-T2.

The point is - you need to use the filter on your particular camera to see if it will cause the issue.[/q[/quote]

Ok thanks for your input. Reviews mentioned that there was no "maltese cross" effect however it wasn't with my specific camera which is a Sony Alpha 7III. Will have to try it out to see for sure.

Thank you for that info.

From the video I watched it looks like the graduated ND is behind the CPl with each having its own adjustment ring.
I've used square ND's in the past but am not sure about this product. Thanks for your reply.

Thanks...I'm not sure either thus the fact finding mission.

Has anyone heard of or used this filter combo? I've researched it and found pretty positive results. Normally costing $109.00 on Amazon. Polarpro has a filter like this and is about 2 1/2 times the cost.Even though the reviews say very good things about it, I'm a skeptical type of person looking for more opinions. I've never owned anything by this company and know very little about them except they are based in China. Thanks for any info/opinions.

That is beautiful...needs a frame to mount somewhere.

Excellent set...a marvel of human engineering!

Your photo makes me want to go there. Beautiful!

Thanks for your reply....funny thing the foreground reeds, boats, dock & water were the primary subjects and I didn't notice the road until it was on the home monitor. Happy New Year

Thanks for your reply and Happy New Year

Thanks and Happy New Year to you!

The boats and immediate water area was the primary subject. I'm thinking that if I would do that shot again with the same background perhaps I change my apeture setting to increase the bokeh. Thanks for your reply.
