have you any nd filter?

ND filters are going to almost for sure be needed.

You are going to want to really shut down your aperture to where you slow your shutter into the seconds. I shoot shots like that anywhere from 3 to 15 seconds but I use ND filters for all of them as I don't like to shut down the aperture past about f16. You might very well need to though and if that is what it takes and you don't have an ND filter then by all means do it.

This shot was shot at f/16 and was a 3 second shutter. However, I was using a four stop ND filter. So that would convert to you opening up the kit lens all the way to f/29 but probably still only being able to get to about 1/4 seconds if you was under the same kind of lighting that I was. I was in a covered forest at about 10am without a ton of sun.

Cheers guys!  This was really helpful!...looks like I will have to look at getting an ND filter then!  Any links or pointers?  I shall have a look on amazon 

I'll have to get them posted up once done.

I will be honest, and maybe I am the only one, but I am just not a fan of pictures like that. It doesn't look realistic at all.

pleasures are different like colours also you are right. a photographer (Ara Güler) said: "modern photography is not an art i think. because people using photoshop and lots of other things. so this photograps are not the truth of life."

Boy did that guy open a can of worms.

Photoshop whether someone likes it or not is Art in and of itself. It would be one thing to say that you don't like heavily manipulated photo's to draw a line in the sand and suggest that putting your work through Photoshop means that you are destroying your art is just crazy talk. I maintain that there is not a real money making photographer out there that does not "fix" their shots after the fact.

And if you guys are talking about the first shot being fake then you are right. The scene would never really look that way to your eye but are you really saying that it is wrong to use your photographic vision to create something using some techniques? Mine is not fake looking. If you stood there and looked at that scene without rapidly blinking your eyes, (fast shutter), that is a pretty fair representation of what you would see. The smoothness of the water is a bit exaggerated but everywhere that you see the water smooth did indeed have smooth white water.   

I'm going to second the Lightcraft variable ND filter suggestion and say that I didn't realize that an adapter ring was an option so I actually bought TWO because I have 52mm and 58mm lenses!

IF the OP happens to need the 52mm version I'd be glad to sell it cheaper than new...it's never been used.
