I need an easy way to remember this stuff, and its impact. It is all still very confusing to me, and Im headed out this weekend, and I am scared I might ruin some good shots, and/or not capture the photo to its fullest. I'm going to go over my books for now, and hopefully somebody out there has some advice.
Owe one other thing somebody might know about. I already have Photoshop 7.0, and ACDsee, but my new camera came with Elements, is there any reason to install it? I know it takes forever to upload the photos from the CF, compared to my old P and S. Thanks guys. |

| Aperture, big numbers = wide DOF, small = narrow |

Photoshop 7 is way better than elements, so you don't need to install that, as for the long upload time, get a card reader, do NOT use the cable to camera option.. unless you really like to wait ;)
a good cardreader can be up to 400x faster than cable to camera.
for a shallow DOF you have to use big aperture, for the deep DOF you use small aperture.
aperture is the opening of the lens, I don't know if you can change those settings on your camera.
metering is the way you mesure light, the "experts" can explain that better...
DOF is depth of field, how much of your image is in focus, with big aperture only the object you focus on will be in focus, and everything in front and behind will be blurred, but with a small aperture you can have almost everything in focus :)
hope this helps.

There are millions of pages on teh web to answer most every photography question you or anyone might have. Some of the info is even correct!
Read your manual. go take some shots varying only 1 to 3 things. look over what happened, repeat with 2 or 3 other variables..etc. then re=read the manual, as much of it will now make sense!
Aperture is cool pics that make it easy to understand.
Exposure, also often referred to as EV (exposure value) is the total amout of light that hits the sensor. You have three variables - Time (shutter speed) aperture (size of the hole the light goes through) and ISO (sensor's sensitivity to light). Metering is how EV is measured, and then you balance the other three to get the image the way you want.
More light: higher ISO, longer shutter speed, larger aperture (SMALLER number)
less light: lower iso, shorter/faster shutter speed, smaller aperture (LARGER number)
If you camera has a P mode, go play with that. Read up on it in your manual and play - it will keep the exposure correct while you can adjust shutter speed/aperture as a 'set'. Very helpful for learning this stuff.

| Thanks guys, and yes it is incredibly helpful. Owe, and Pro fate, you are right there are a million websites explaining this stuff in full-excrutiating detail, but the people here are the best in Digital Photography why would I go anywhere else. Come on man......Represent. LOL. |

Hereâs a few things that helped me, as I always found âlargeâ aperture (1.4) and small aperture (f/22) to be counter-intuitive.
The aperture number relates to the number of circles you can fit into a lens. For example, f/22 is actually a very small opening to let light into the camera. You can fit â22â of those openings in a lens (picture is as 22 Cheerios on a lens filter). f/1.4 is a large aperture, as you can get 1.4 circles on the lens (picture a mini donut on a lens filter).
Small/High aperture (f/22) = small opening = deep DOF (i.e., more stuff in focus)
Large/Low aperture (f/1.4) = large opening = shallow DOF (i.e., less stuff in focus)

Nah, stay with the food analogies â works better. Hey, thereâs also the âwater facetâ analogy! (turning off the water is like âstopping downâ, smaller opening = less water through the facet = less light into the camera, yada yada yadaâ¦) |
