Refresh my memory...

It has been about 10 years since I picked up an SLR let alone a DSLR.

Okay I need help remembering....

Shutter speed: How long the shutter is opening letting in light (water fall moving rather then frozen in time)

Aperture is the same as f stop right....F stop deals with depth of field. The smaller the f stop the shallower the depth of field. The larger the f stop the wider the depth of field.

ISO: I have no idea....I set mine of Auto.

Anything I am missing......

what kinds of different situations would you change them to....



A picture I took in Maui at the Lava Tube

The longer you let light in ( 1sec. as compared to 1/2 sec.) the more a moving subject will blur. Like the waterfall. Shorter shutter speed will freeze it. Longer will let it blur. Same with kids.

The f-stop or aperture is how wide the lens is open.
The aperture lets in varying amounts of light. Like shutter speeds, apertures are "stops". That is, changing the aperture 1 stop halves or doubles, the amount of light let into the camera. So going from f5.6 to f4, with all else being the same, the exposure doubles. Going from f5.6 to f8 cuts the exposure in half. The larger the f-stop (lower the number, such as 1.8) the less DOF you have. A smaller f-stop (higher number, such as 16) the more depth you have.
To start out you might try Av mode or Aperture priority. You set the f-stop, the camera will find the right shutter speed. It will give you a good idea of how the depth of field changes with f-stops.
Later switch to Tv or shutter priority to get a better idea of how shutter speed affects your images.
A smaller f-stop (f16-f22) would give you greater DOF for landscapes. Larger f-stop (f3.5-f4) shallower DOF to blur (or de-focus)backgrounds, say activity or distractions behind your children.
Hope that helps. It will all come back in time.

Ok so f-stop and aperture are the same thing.

I will have to post some pictures and tell you what settings i used and maybe we can go from there.

One other way to help remember is that the shutter speed is the quantity of light passing through the lens to the sensor. The aperture is the quality of the light.

I hate to say this but, another way to remember is to think of a water faucet.
How long you let the water run is the shutter speed. How much you open the faucet is the aperture. If the faucet handle had numbers on it, each would represent an f-stop.

There are so many ways to remember. Pick something that works for you.

Oh geez....haha when it comes to fstops; its like gibberish.

You guys will have to test me sooner or later to see if I am actually getting fstops.

Your questions should all be covered in my Tips and Tricks feature. I did a three part article on exposure which deals with shutter speed, aperture, as well as ISO.
