I just don't understand it. I don't understand cameras. I don't understand how you set an aperture and what the point is of trying to because if you change your zoom it changes the aperture.
The only thing I understand about aperture is the smaller the number, the larger the aperture = smaller depth of field. It took me for-ev-er to finally remember and grasp that. But again, I don't get trying to set the aperture.

I need photography for super dummies.

It has always confused me too. It feels as if the aperture numbers and the exposure numbers are the opposite way round, right?

I found this last night. Excellent (easy) explanation of the very basic principles. The guy has a great instructional voice. I wish they'd post more. I'm going to have to check out the website.

Ok, I think I may have had a brain-breakthrough.

When they say you can set your aperture, you don't get a full choice at any zoom level. But you do have at least one other option. So if I have my camera lens all the way in (no zoom) the aperture is 3.1 (the lowest mine will go which is a bummer, my old model Canon has 2.6). But I can change it to 8.0 without zooming. It's my only other option. If I zoom the lens to get a 3.8 aperture, my other set option is 10.0. On auto, you only have the one setting the camera gives you based on your zoom level.

Oh good, you worked it out. It sounds more versatile than you feared.

I had a quick play with my automatic camera last night at gone bedtime and I couldn't work it out. But it has no manual override so I wouldn't have been able to use it. One day I shall get a digital camera back for my beautiful Pentax film camera, but not in the foreseeable. DH had a bit of a paddy at the weekend over the credit card bills...

Now I just have to get that whole aperture/shutter speed/ISO thing worked out. I have a basic understanding now what they mean and what they do individually. Just have to figure out how to work them all together.

Dredging up the memory here...

You get the cleanest photo from a small aperture, short shutter speed and the fastest film. For that you need superb light. As soon as you have any zoom you cut the light down, so you have to have a wider aperture and/or a slower shutter speed.

The lower the light level you have, the slower the shutter speed needs to be, so you're more likely to get a blur if you or your subject move. The wider the aperture, the more light echoes you get, and the grainier the image will be.

The skill is in having the smallest aperture and the fastest shutter speed for your light conditions and your subject.

I think that's right....

Yeah, something like that. But you have to factor in ISO. If it was just 2 things it'd make it just a little bit easier. Instead, you have a love (/hate) triangle.

I would love to add that this thread is cracking me up! It sounds like you are getting it, Tam!

Too bad it's too darn cold to go practice outside. I should probably take notes before I practice though.

Did I get it right Stephanie?

ETA: and how DO you factor in ISO?
