Lets see if Suzanne and I can get you up to speed on your XTI (and anyone else)

Ok some jargin

ISO = the film speed, When you had a film camera depending on what you were shooting depended on your film speed. ex. fast paced action you went with 400 - 800 most likely.

Aperature - The amount of light the camera brings in to expose a picture. I LOVE AV setting. The smaller the number (ex 2.8) the more light brought into the camera, the blurrier the backgroung. Great for portraits.

THe larger the number (ex 8 or 10) the least amount of light, the slower shutter speed but a crisp clear background, and b/c of slower shutter speed more likely to blur picture. Definately need a tripod.

Shutter speed = How fast the shutter opens and closes to stop the action or blur the action. the numbers to the right in your view finder is the shutter speed. If it is a 60" that (") means FULL SECONDS< LONG SHUTTER SPEED blurred action. The 1/200 is 1-200th of a second. Fast shutter speed stop fast action.

Now I LOVE TO play with the AV mode and Suzanne really helped me to understand how to adjust my Aperature to fix a blurry picture.

For instance you want a portrait picture you choose the lowest aperature your camera will allow w/ the lens you have. You take the picture but it is blurry and you notice the shutter take awhile to open and shut. So you slowly but surely increase your aperature till your shutter speed is fast enought to prevent blurring, yet still get your subject as the main focus w/ a blurry background.

Jillian now go play...... Does it make sense or am I telling you stuff you already know??? If so, ignore this post and I will delete it.

WEll Suzanne, How did I do?? I had a great teacher, who is a great mentor and will keep helping me along the way.

Oh yeah that is YOU!!!!

ahh. thank you so much. this helps me enormously. Darren got a few books from the library but its not like I have time to sit and read it and when I do have time I don't want to have to search for all important things for the quick learning.. if that makes any sense.lol

I took this one with out the flash next to a window. I cant wait till summer when I can take more outside in natural light.

Tricia · 03-07-2007, 05:13 PM

Jillian do you have an extra flash (not sure of that particular name) Or are you using your built in flash? The reason why I am asking is b/c I think the color tone is off. Somethign I was experiencing w/ my built in flash. It wasn't strong enough to give good lighting. I also found w/ using my flash to point it straight up when inside so it bounces off the ceiling.

Also I wanted to tell you about the aperature. If you take a piece of paper and make a cone. If you point the cone out with the big side facing you. This represents a small aperature. The big part of the cone facing you represents that large amount of light coming into the camera to expose your picture.

Now if you turn that cone around, this represents a large aperature and a very very small amount of light exposing your picture.

Make sense????

Oh by the way, I like to read books not manuals, I would rather someone explain to me in laymens turns vs me trying to figure out what they mean when they write a manual....

Aww! Thanks Tricia! I love talking about photography, I'm always up to babble and play with pictures!

Wanted to add this statement...

Another thing you can do is instead of increasing your aperature (making it a smaller number), expecially if you are as wide as you can get, is you can bump up your ISO...that will also increase your shutterspeed as well!

Nice Job explaining Tricia. A handy thing to know to help prevent motion blur with your camera is to make sure your shutter speed is 2x faster than your focal length. So if you have a 50mm lens on you should have a minimum shutter speed of 1/100 to prevent camera shake from handholding your camera while taking a picture. If you have your 18-55mm zoom lens on and you are taking a picture at 40mm you should have a minimum ss of 1/80. NOW...take into account that is just to prevent blur from YOU as you press the shutter. If you add jumping of moving kid into the mix, a breeze moving a flower, etc. you will have to have a shutter speed higher than that to freeze the action. To get Caleb in focus I usually have to have a minimum ss of 1/125 at a focal length of 35mm or 50mm...1/200 is even better. Play around with it, you'll find your comfort zone! The more light you have the faster your shutter speeds can be so find the light!!

Wow Now that is nice to know.

So what about this.

Is the 50mm mean you can be 50 mm away from something and have it in focus?? How does that work?? Or is that a different term?

Mommy2Meghan-Caleb · 03-08-2007, 12:29 AM

50mm is the amount that the lens magnifies I believe. ??? I'll have to look that up.

I think you are right, b/c during one of our classes they showed one picture at the different focal lengths and the difference between 18mm and 300mm, just was how much the camera could zoom on a picture.

So what is the term for the minimum distance the lens can be from an object and still focus???
