Blurring Water and the Sky to Create Motion..?

[photoshop]

Guys,

Whats the best settings to use when taking pictures of water when it is flowing or the sky to create that look of motion rather than it looking static?

Example:

I've seen tutorials on youtube where they use Shutter Priority mode with a setting of around 1/4 of a second but when i do this i just get a picture filled with white light - like a sheet of plain white paper!

What am i doing wrong?

Camera is Sony A200

My god this is complicating. Damn

Lovely pic SteveOBHave. Thats exactly what i am talking about!

What ND filter should i be looking at buying?
Lens is Sigma 10/20mm

These are the best ones I've managed on bright days without the aid of an ND filter.

What settings did you use?

So try to stick to F/11 or less

by less you mean f/lowest number - f/11 ?
or f11 - f22?

This shows in know sweet F.A about photography!

Should the Hyperfocal Distance be used for all shots to get plenty of focus then?

Would this then render the AF on my A200 useless as to use Hyperfocal Distance would mean manual focusing?

You can still use autofocus, just aim at the point you want to use for hyperfocal focusing, and then switch it to manual so that it doesn't refocus when you frame the shot. Also, reading 'Understanding Exposure' is a very good idea, it will help you with understanding F numbers.

Theres a few called that. Whos the author?

The B+W 110 ND filter is great because it gives 10 stops, problem is they are extremely hard to get hold of right now and prices have rocketed due to supply/demand.

They are bloody expensive!!!!
Cheapest i can find it is £80 for the B+W 77mm ND-110 (3.0) SH Filter

Is that the one i should be looking at getting as there are a few ND-110's....

Should i get the B+W 77mm ND-110 (3.0) SH Filter ????

That's the one you want if you want silky smooth water. Its a 10 stop ND so will require pretty long exposure times. Really nice filter though. All my filters are now B&W as they top quality. If long exposures is something you are into, then the B+W 77mm ND-110 is well worth the money.

Thanks.

Whats about these:

B+W 77mm ND-106 (1.8) SH Filter (reduces light by 6 f stops)
B+W 77mm ND-102 (0.6) SH Filter (reduce slight by 2 f stops)
B+W 77mm ND-102 MRC (0.6) SH Filter (reduce slight by 2 f stops)
