Hi,.. I am going on a photography field trip where there will waterfalls. It is a day light event. I will want slow my camera down for the waterfalls. I am going to give the Cokin Filter system a try. What filters would be good for that sitituation.

I didn;t like the cokin system. It never fit snugly, was to flimsy and cumbersome. Instead I use these now:

ΓΆ€ΒΆ Heliopan (8x)
ΓΆ€ΒΆ B+W (8x)

An 8x (exposure adjustment 3 stops) is likely what you need for the purpose.

@zeuszen - Wow,.. a little pricy I see. Right now that is somewhat out of my budget right now. I will have to work some other method for now. Thank you for your info.

There are cheaper filters as well...

If you are looking to get "smooth" water, you'll want exposures of 1 second or more. In order to get exposures this long in daylight, you can be looking at needing six to 10 stops of reduction. Example:
We have a daylight exposure of 1/100 @ f/8 @ 100 ISO, and we want 1 second or more. We can reduce aperture, go to f/16. That will get us to 1/25s. You'll need an additional five stops, in this case, to reach 1 second.
B+W makes high-density filters that are (relatively) economical. I have a six-stop and a ten-stop for this kind of work. One caution here. With a ten-stop filter in place, you will not be focusing through the lens.
FWIW, remember that it is possible to shoot multiple images and combine in post to imitate a longer exposure. The technique is the same as used to stack astro images. So if you can only get to 1 second and want 10 seconds, take ten images and stack in post.

ETA: Link to B+W 6-stop filter

Hi, I'm a newbie in photography. I just bought a Nikon D5100 and a circular polarizer. WOuld you please let me know what are the most usual settings used for great photos in daylight-specifically what shutter speed and f stops you reccommend for regular photos? I know water needs longer shutter speeds and so on. But let's say I'm in forest or in beach or out in the park @ 11 am, what settings do you suggest to use?

And if I need a filter, would it be worthy if I don't want to spend more than $50 on it?

Thanks so much,

These guys have a little bit better price on filters than you will likely find at the big shops-
2filter.com

All they sell are filters so it is pretty easy to get someone on the phone there who knows what works well for a particular use or budget. I called them the other day when I was looking for a 105mm Circular Polarizer and the woman I spoke with was very helpful. She didn't have what I wanted in stock, but was able to tell me she personally measures both Lee and B+W CPs and the thickness was exactly the same on both. So I went with a B+W over a Lee from another source and saved myself $70 by going confidently with that brand. Not sure I would have gotten that info with a call to B&H despite their usual good service...

Thank you @ JamesDowning and Brent! And I guess the speed should be according to the camera meter if I choose the F stops as suggested here?

You wouldn't have a meter if you where using that rule :)
