I went out yesterday as I found my ND8 Filter, I decided as I live next to the canal to test it out, the water was very choppy like the sea, but I just wanted to know what I was doing wrong?

Below is an example of what I mean..

This one I shot at, 1/4 F22,

This one below..

I shot at 0.4 and F22, It started becoming over exposed and I know thats because too much light was being filtered into it, i thought it could be the amount of sky I was getting in the image... but still unsure..

Can somebody help

very much appreciated

So can no one help me at all? Sorry to ask again or to repeat myself.
 
Think you need a stronger ND filter or possibly try stacking 2 together.
You could also try the welding glass thing, very cheap to get from fleabay.
 
I assume f/22 is as small as you can go. Did you set the ISO to its lowest too, usually 100? (Sorry if you know all this). ND8 on a bright day isn't going to be enough - it's only 3 stops.

I would suggest an ND1000 if you have the time to order one, they vary from £15 upto £100+ but well worth it imho, If you look for an 82mm version you can then buy some filter adaptors so that you can use it on all your lenses ;) I use a Hoya 82mm that I screw into an adaptor set which goes down to 49mm (although I don't have anything smaller than 52MM thread etc)
 
There must be 5 stops between the brightest part of the sky and the shadow detail. You need to try a soft grad over the sky which will balance the exposure a bit better and then use a 10 stop after calculating the exposure. Even then you'd need to do a bit of PP on it to get the best out of it.
 
Are you thinking that ND8 is eight stops? It's only three... 2, 4, 8 = 3. Eight stops would be marked ND250.

Log (base 2) of the ND should give the number of stops. ND250 ought to be marked ND256 and ND1000 ought to be 1024. But then I suppose we all put up with 1kB, 1GB etc without really thinking about how many Bytes there are ;-)

LOL What would you have shutter speeds marked as then? :D And bearing in mind I've never used one of these 8/9/10 stop NDs that has been within half a stop of the marked value. They even vary a bit batch to batch.
 
There are 10 types of people in the world. Those that understand binary and those that don't.

There are two types of people in the world - those that think there are two types of people in the world and those that don't.
