Long exposure on a Nikon D50?

I have just bought a Nikon D50 and wanted to try out the long exposure with water. How ever I set the settings on:
Manual
ISO 200 (the lowest)
Aperture on F 22 (the highest)
Shutter speed about 5 seconds.

Every time the photos come out bright white on these settings. It really puzzles me and even my A Level photography teacher. The weather is usually bright and sunny (I believe this could be a contributing factor) It is fine with light trials in the dark. Could anyone shed any light on this for me as I cant find anything to help me. Thanks alot.

Nicu Portrait Photography?

Hello! I have my first NICU portrait session coming up in October. I'm still learning my camera but was wondering if someone can help me with what settings to use while in this type of setting.
I have a Nikon d3100 with a 50mm 1.8g lens as well as a 60mm Macro lens.
I usually shoot on P but would love to learn how to change aperture and focal lengths to make this session a success!

Thank you in advance!
