Which Filters?

Im planning on buying some more filters...I think I can afford 3 new 100x150 for my cokin z-pro filter holder!! I want to buy Singh-Ray...My question is which should I buy?

I know I need 2 Grad ND Filters but whats the other filter that makes the most sense...?

I already have a 2 stop ND filter and a circular polarizer. Should I get a 2 stop and a 3 stop grad ND, hard or soft?

I shoot mainly landscape!

Thanks

Really, it's hard for any of us to tell you what you need. I don't know where you live--you gave no clue. I like the hard edged filters and use 2-stop and 3-stop. But I live on the prairie where the landscape is flat. Do you? I don't know. To determine what I need, I always look at my photos and analyze them. Your photos will tell you what photo gear you need.

If you are shooting in the mountains where there is not a level horizon the soft grads are best, at the coast where there is a level horizon a reverse grad might be the better choice. As Kent said it all depends on where you shoot. A 2-stop and a 3-stop would be best whether soft or hard. Many photogs have abandoned grads and are simulating their effect in PS...I would rather get it right (or close) in camera and minimize the amt of time spent in front of the computer.

Thanks for your reply guys!!

I do live in the mountains so I guess soft grads would be best!!

Im an avid HDRer and understand that some people are starting to duplicate grads in PP but I also like to get it right in camera!!

Thanks again

I live in flat country. Of NGDs, I use 3-stop hard most, then 2-stop hard. I use my 2-stop soft the least. I use a 3-stop ND and haven't felt a strong need for lesser ND filter. A reverse NGD is on my want list, as is Singh-Ray's variable ND filter.

Personally, I think ND grads are evil! I really don't like them very much. I prefer to make my shots when the light is just right. When I do need ND grads, I use 2 and 3 stop soft, mostly.

Since I shoot 4x5, I have found that my hard edge 3-stop works well with my 90mm WA and the soft edge grads work best on my longer lenses. The hard edge filter is also nice for working with lake relections where I have a straight horizon line.

I have a 2 stop and 4 stop neutral grad soft edge filters, and when I need a hard edge I just put it in the coken holder upside down, so the edge of the filter becomes the hard edge. This has worked well for me, as the camera tends to give a slight blur at the filter edge and you can not see a line on the photo. Just my 2 cents worth.
