How do you do long daytime exposures? Say you want to capture the flow of water or what not, but it's a bright sunny day.

My D50 only goes down to ISO 200 and the lens to about f22 which isn't enough to do long exposure, the shot just ends up white.

I presume there is some kind of mechanism to adjust the balance or something?

Forgive me, i'm new to all this.
 
ND = Neutral Density, basically a filter of dark glass that limits the amount of light passing through, the higher the number the more it blocks...
 
After reading this I had a quick look at the usual places for a 10 stop filter but can't find them? Max I saw was x8 and that was £55 so I guess those are expensive lol

I used some welding glass which gives around 10 stops, around £2 or £3 from ebay... There is a bit of a greenish tint but if you use RAW then this can be fixed in PP :)
 
corkin p series filter system it allow you to stack 3 nd filters plus what ever screw on lens nd filter you got. then simply select av mode (Aperture Priority). thing about doing this is that you need a good solid tripod and shutter release cable because the slights knock or movement will mess the shot up. ideally these shot are to be taken either at dusk or dawn when the light level is low so single nd4 will do if you shooting water then a polarizer will be needed. but if you stack multi nd filter on top of each other then taking long exposure shot in high light level is possible all depend on the stacking of the nd filters.

Wouldn't do this. Cokin filters don't stack well. You'll get magenta colour casts.
 
Yes those are the shots i'm talking about.

So i can adjust the EV - I know how to do that, what does it is actualy do? And can I then still use the built in light monitor to get the correct exposure despite a slower shutter speed?

Though to do it properly, looks like need a strong ND filter.
 
LightCraftWorkshop do a decent ND500 (9 stops) filter as well (but avoid the fader). Mine cost me £65 for 72mm but apparently they're a bit cheaper now. I originally bought a B+W ND110 on ebay but sold it on for slightly more than I paid when I got the LCW filter. the B+W one has more of a red cast as well.
 
i haven't had any magenta colour casts so far using them i know that other have but they opted for the cheaper make one that are similar to corkin to save move. but the offical one don't
