So I've been asked by a fellow avid photographer "How to shoot water and show it flowing?".
Firstly I must admit I have only done this a handful of times myself and some of my attempts were far from perfect, especially when I got them on the computer!
So the question was "Do I just shoot with a low shutter speed?"
Firstly yes shoot at a low shutter speed of 1/25 or below usually 1s is about right! It all depends on your surroundings, and you have to watch your exposure you don't want to blow the image out or it be too dark!
Remember the ISO, Shutter Speed, Aperture triangle in the first instance and how each effect one another! Watch you're exposure and take some test shots!
My Nikon D3100 is great for information as in the "Guide Mode" it actually tells you some simple setting's such as how to show water flowing etc. You can then dial back to Manual/Aperture/Shutter Speed priority modes and dial in those settings! Great when you're a little unsure or have a mind blank!
I'd recommend "S Priority Mode" on a Nikon. Canon is named different I think but same thing! In "S Priority" mode all you really need to think of in the first instance is setting your shutter speed and the rest is taken care of! Yes then you can change your ISO etc but I'd leave this at around 100/200 and change only if necessary! Remember higher ISO increases noise/grain in the photo which isn't usually wanted! So think about other ways to get more light before boosting that ISO.
Now the most important part! A tripod and a remote shutter release cable! Without these you're picture's will almost certainly not be tac sharp and you will get motion blur!
Follow these simple steps and you should get some dreamy waterscapes!
This photo was taken in a wooded area in very low light at around 5pm on a dark January evening. The settings were / NIKON D3100, f/13 @ 58 mm, 1s, ISO 200, No Flash /
