long Exposure

[AyTee]

Hey Yesterday I went to shoot some daylight long exposures ... I used a nd filter and used the highest F/stop (f/22) and also hooked a lens hood to the camera all of that to reduce the light and even though the picture was way over exposed so what else can I do to get the proper exposure???

Lower ISO?

Lower ISO?

Darker ND filter?

What are you going for with such long exposures in daylight?

The lenshood won't help. Your best bet is to try:

1-Film with lower ISO
2-Darker ND filter or several ND filters together
3-Using a polarising filter with your ND filter

If your camera has TTL (through the lens metering) and you follow its recommendation when using your ND filter, your picture should not be way over exposed. Basic principles of exposure are still valid when using ND filters: if you leave the shutter opened for too long, your picture will be over-exposed.

How long do you need your exposure to be? The "correct" shutter speed for a sunlit subject with ISO 25 @ f/22 is going to be about 1/12 of a sec. If you need longer than that you'll have to use the filters suggested above, or wait for the evening.

Yeah and waiting for the evening is free!
