Here's a thread for your burning questions about photography. I'll do my best to accurately answer them, and move them to the Photography 101 thread for reference.

How do you do the rolling waterfall effect?

It's a relatively easy answer; leave the shutter open longer.

.5s will blur the water a bit, 1s, 3s and so on will make the water look smoother. Leave the shutter open long enough and the water won't look like water any more.

Obtaining the effect requires you know about exposure and how shutter speed, ISO and aperture effects the exposure time. A tripod, or sturdy surface is a must, otherwise everything including the water is blurry.

While you could probably use Auto to make the effect in low light, like late evening or early morning; you are really better off using Manual or Aperture Priority. Shutter priority might work, but you could easily change the value to where the aperture can't compensate for your desired shutter speed. (Either too high, or too low).

You could potentially make the effect during the day by employing the use of an ND filter that screws to the end of your lens. It acts like sunglasses for your lens and cuts the amount of light down by a specific amount. ND filters come in various density values. I believe they can be stacked - I'm not sure, because it's cheaper to be there in good light than it is to make the photo in bad light.

Try it at the beach sometime... waves will do the same thing. It's pretty cool.

Using a fast shutter speed, water is frozen in time and individual droplets are recorded.

Using slow shutter speeds as suggested, gives a soft, rolling effect to water flowing over falls.

No real tips other than keeping your gear safe and dry. I can't remember if I covered the positive exposure bias for snow - where you have to over expose the scene by 1-2 stops to get white snow - otherwise, it' gray.

Keeping your gear safe...

Before you go inside take your cards out and put them in your pocket. Either put the camera back in the back and zip it up, or put the camera in a zip lock and zip it up. This has to be done outside or it's pointless.

What you are trying to avoid is moving from a cold dry environment to a warm moist environment. Just like eye glasses, when you walk indoors, the lens will fog up - but it can also fog up on the inner glass elements. That moisture will attack electronics. If this happens often, or the moisture sits in the lens for any amount of time, it will start to grow mold in the lens.

The camera body is the same thing - except condensation will form on the electronics and stuff.

I keep a few packs of silica gel inside my camera bag, and leave the camera in the bag over night so it will warm up gradually. The silica gel will help absorb moisture that may get in the bag.

Subaru Imprezas sure help while out shooting in the snow I hear.

How could I not have known about this place Chris!

I try to keep my camera in the truck to take pictures of work ive done.

it is kept out of the direct sun, but still in the heat ( in summer) and cold in winter, will this hurt the camera?

It will probably cause more problems with batteries than it will with the camera itself.

Like anything electronic, moisture is the enemy, so keeping it dry between temp swings could be a challenge. Example is warming the car up then walking outside in -20, the camera may fog up on the inside, water could condense on the inner lens elements and the electronics.

Other than the lens fog and battery issues in the cold, it should be fine.

What's a good source or website for learning how to take good pictures and using some manual controls? My new camera has some manual controls and I'd like to learn more about how to use them properly.

I have the second edition of Understand Exposure. It helped me more than any site. They're on edition 3 now. http://www.amazon.ca/Understanding-Expo ... 402&sr=1-1

Or try http://photo.stackexchange.com if books aren't your thing

Just picked up this book at Indigo today in exchange for one I didn't want that I received as an Xmas gift. Looks like a good reference for a broad range of topics.

How about some purchasing advice on a lens cleaning kit for smudges, dust particles etc.? Some look cheap, some look overly complex.
