Aperture

Aperture is the focal length divided by the diameter of the pupil. This basically means that you focus in on a certain spot of your emphasis and it blurs everything else out just like your pupil does when your focusing on something. The one with the crystal would be a small hole because its focusing in on a smaller object. when you have a big number this means that the hole is smaller. For the one with the cheetah im using a smaller number which means it will be a bigger hole so it captures much more than the cheetah.

Iso

FlashIso 400Iso 5000Iso is basically the film speed. It refers to how sensitive the film/pixels are to light. when using the iso in my pictures it showshow graining the pictures get when u put it on a high ISO. With the five thousand one right above you can see how grainy it has gotten. When using the flash it takes out some of the lights you want to see but it doesn't give you a grainy picture at all. You have to becareful when using a fast ISO because it tells us how much light comes in and at what speed.

Flash

The pros about flash are it freezes time and it eliminates blur. Another pro i found out is that it also adds light to the picture if there isn't enough light. there are also cons about the flash, they are makes the light ugly sometimes, may disturb the subject, Red eye and Hot spots. Flash is a good idea when you can't see anything at night or when you need to see your emphasis with out any shadows. When flash isn't such great idea is when you want the natural light to appear to show us what really happening and gives us interesting figures and shapes. The picture above is great without the flash because you get all the natural light giving off by the carnival. You see the natural light beam right back up off the lake and it takes right back up to the amazing light.

Metering

What metering does is it measures the amount of light that is in the room or around you. The way to activate the meter is by pushing the shutter half way down. In the first meter picture above the camera only read the meter of the computer and it was the only thing to pop up in the picture. In the second picture I metered in on my subjects head to get the light to the way it was. It over exposed the computer to too much light that's why it is so bright. Spot metering can help by focusing in on what you really want to emphasis on rather getting a light that you didn't want and not capturing what you really wanted.

Unknown

To me your dream is a little up ending because you have so many things going on under the sea. When stuff is under water it means that your struggling and you probably having a difficult time take things to heart or to mind. The huge eye ball looking down upon you and whats going on probably means that someone that you love dearly like a family member that has past on, is looking at you and is enjoying everytime they see you. You also describe a gym with graffiti on the bleachers. This looks like you play sports such as basketball or something, while the graffiti looks as if you have had a difficult time growing up with gangs and drugs near by. You also say there are vans or cars there. This probably means you want to get out of the neighborhood and to do something better with your life. I also heard you say your in a tree? This seems as if your hiding from what's going on around you and you don't want to deal with it anytime soon.
