As an example using your situation where the image was dark at ISO 100, and assuming your f-stop was set to f/8, you would need to have a longer shutter speed. If it's also windy, you may have to add some weight to your tripod hook (if it has one), some folks hang their camera bag to keep it rigid. Don't be afraid to play around with the three settings to see what best works for you.
