The beauty and the beast of Neutral Density Filters .... help please

[Andrew]

If you use a screw-on GND your horizon will always have to be relatively close to the center of the photo. I do have a holder from Cokin and use a GND from Singh Ray but have just free-handed them in front of the lens a couple of times. Good quality variable NDs are rather $$$ for me so I'd need to be sure of using them regularly. So far I've been able to use camera settings and a polarizer to get what I want. I did borrow a variable once from a friend on a club outing to use with the obligatory misty ocean shot but I just can't appreciate that look I guess. Foggy water and milky falls just don't look real. I have been looking at some other long exposure practices so I may have to see if Santa can help me out with the variable. Just not sure I'd use it that often though.

Well I done it ... bought the Cokin set of grads, and the B+W 10 stop ND filter. From a company in the states, which I can highly recommend. They are very good when it comes to communication, and helpful in their customer service. Helps that their prices are reasonable as well .. so now i can plant my tripod somewhere and open wide ....

In the old days I used two polarising filters and turned one against the other to work as neutral density. Can't do that with the new sandwich type the outer filter needs to be plain polarising without the quarter wave filter sandwich.

Not a clue why they call the sandwich type circular as they are clearly not circular except in shape. It would be rather pointless to turn a circular polarising filter.

I got out my old cokin type filters and tried them with the D-SLR as an experiment. However found it far easier to do it all in Photoshop post exposure. My idea was to use graduated filter to increase the dynamic range by darking the sky. But using a polarising filter and/or bracket and if necessary combining later seemed to work better for me. Always seem short of time on location.

Woops - I missed this thread....and have strong advice on the issue.

If you enjoy and are good at PP, there's no need for these filters in most cases imo - HDR will cover your butt and then some.

If you hate PP and like to get as much done in-camera, then yup this is the way to go...... and I recommend the Cokin Z system from the get go.

Hey thanks Marko (and Merry Christmas to you) .... I have meanwhile bought a Cokin P series filter set - including 3 ND grads, and the B&W 10 stop grad. I want to experiment with stuff where lots of traffic would otherwise disallow for proper viewing ....

Merry christmas as well!
Cool and good on you - you will love the set! and I hear exactly what you are saying on making people disappear w/the 10 stop.
The reason I recommended the cokin Z btw is that at least for the lenses I own, the P series was not large enough to cover at least 2 lenses and vignetting was a constant problem and source of frustration.
Hopefully this isn't an issue for you.

I would not think so, Marko. Most my lenses feature a 77mm filter ring or smaller ... Glass that is much larger is also much heavier on the pocket book. Amazingly enough, filter diameter over 77mm is a deterrent for me when considering a lens; just don't want to spend the additional money on filters. So there is my limit, so to speak ..
