I have seen lots of photos of streams and small water falls where the water seems to merge together
I know this is done using a filter …..but I need your help to find out which type……Thanks
Neutral Density filters are usually used for this type of shot. They come in various types and strenghts. Some are graduated, which would allow for the long exposures without burning out the sky.
Achieved by a slow shutter speed of approx. 1/15 or slower.
If you can’t stop down enough to give you the slow shutter speed you require, then a neutral density filter is what you want. These are rated by the number of stops of light that they block,
I took these with no filters, you don’t need a massive exposure time, I think I was using between 0.25s and 0.6s, and it was quite a sunny day. It helps if there’s loads of water running so if I want to shoot powerscourt I wait until it has been raining hard for a couple of days – doesn’t cause much limitation in Ireland! I shot them in shutter priority mode and this makes it pretty easy to set up.
10-stop ND filters are becoming quite popular and these have allowed people to do some pretty cool stuff, as it slows the shutter speed down so much people disappear from the shot if they are walking through. Makes shots of the sea velvety smooth. I havn’t taken any falling water shots since I got my ND grads, but I’m looking forward to testing them out, and they’ll certainly help avoid blowing the highlights…
