You use a neutral density filter. It cuts down on the amount of light that hits the sensor so you can leave the shutter open for longer periods of time.

If you're looking for a screw-in filter, B+W is the way to go. Just make sure you get the size that fits your lens. Never really had any color casting issues with it, even on their ND 3.0 filter. Personally, I find myself using a ND 1.8 more often though I have both. There are also drop-in filters like those made by Lee, which come highly regarded but are leaps and bounds more expensive. Multi-coating is nice to have, but more important for polarizers than filters. It really depends on how much you're willing to spend. I have no idea what a "hot mirror" is, but I'm thinking that you're referring to a hot sensor or hot pixels. When you take long exposures, with an ND filter for example, the sensor will continue to heat up as long as the shutter is open. Hot sensors produce more noise, which hurts overall image quality. Any filter you put in front your lens is going to have some adverse affects on your image, most of which can be easily fixed in post processing. Contrast, tones, and all that can be adjusted in Lightroom after the fact.
Circular B+W that is threaded for my wide angle lens, 77mm. I used a 6 stop filter. I have heard that the Cokin ones can have some bad cast and can be pretty punishing on your sharpness. I have two lenses that are 77mm, and they happen to be 2/3 of the lenses I use most. I will see if I can do a step down ring to put it on my Tamron 28-75 f/2.8 at some point.
