Nice, but again, with the high contrast, your highlights are getting blown to smithereens (like the white shirt on pix #2). Try getting the WB down a notch and all will be perfect. Sharp images, nice composition.

Thanks, i'm a photo noob and could use any help. I'm just now getting to where I won't use Auto and have started messing with ISO. What exactly does apeture and shutter speed effect? Could you give me any idea of when they should be adjusted and how depennding on circumstance.

There are a lot of threads on this forum where this question has been answered. In addition going on a search engine will give you all the knowledge you could ask for - but I can give you a brief rundown:
1) Shutter Speed - This is how fast the Shutter opens and Closes exposing light to the sensor (for SLR Cameras) for your point and shoot it is how long the sensor choses to capture the light. The quicker the shutter ie: 1/800, 1/1000, etc. the faster the light will be captured and the more "frozen" the action will be. The slower the shutter ie: 1/20, 1", 2" - the more light will be captured but the less "Frozen" the action will be. If you are shooting a sporting event and you wanted to freeze the action you want at least a 1/150 of a shutter speed (Give or take). If you cannot get this shutter speed you will either have to adjust your ISO (See 2 Below) or adjust your aperture (See 3 Below) or use a Flash. (See Picture Below - This was a long shutter - 8 Seconds long - and an aperture of f/13 (See #3))

2) ISO - How sensitive the sensor is to light. This is very similar to different speeds of film. The Higher the iso - ie: 400, 800, 1600 etc. quicker light wil be captured by the sensor and the easier it is to get fast shutter speeds indoors. The higher the ISO, the more grainy the image is. If you are shooting indoors at a sporting event you will need to bump up your ISO to get a fast enough shutter speed to "freeze" the action.

3) Aperture - this is a little hole in the back of your camera between the back of the lens and the sensor. The Larger the hole (lower the f/number ie: f/1.8, f/2.8) the more light can enter the camera quickly. The smaller the hole (larger f/number ie:f/5, f10, f13) the slower the light is fed into the camera. In addition, the lower the f/number (f/2.8) the less DOF (Depth of Field) you have, which means if you are focusing on a close object the background will be out of focus. The higher the f/number (f/13) the larger the DOF (more in focus the entire frame will be). The DOF is much greater on point and shoot cameras because of the smaller sensor therefore you don't have to worry as much about your picture being out of focus if your aperture is larger (Smaller f/number). The attached picture below shows what an SLR can do with a small DOF (see the grave in focus and the trees are out of focus & blurry). - this was shot with a Canon 20d, 50mm f/1.8 lens @ f/1.8

I hope this helps - and I suggest going online and searching for more articles on DOF, Aperture, ISO and Shutter speed - it will really help you understand your camera
Good Luck
