Stitch, thanks for the AV tutorial. I wasn't sure how to change the aperture in AV mode. I did take these the other day for the DOF thread but didn't have my manual with me; it was the first time I had much luck using AV mode. I played with other settings as well but I wish I knew then I could adjust the aperture using the omni-button - I could have improved the bokeh with a wider aperture.
Man, there's always something new to learn with this camera!
Focal length: 37.8mm (35mm equivalent: 238mm)
Exposure time: 0.0025 s (1/400)
Aperture: f/3.5
Whitebalance: Auto
Metering Mode: matrix
Focal length: 32.2mm (35mm equivalent: 203mm)
Exposure time: 0.0016 s (1/640)
Aperture: f/3.5
Whitebalance: Auto
Metering Mode: matrix[/QUOTE]

This I will have to digest for a while, LOL. But I will print it up and keep it with my camera so next time I'm out I can give it a try. Anyone else in??LPZ Stitch said:Getting into manual mode: Manual mode can see very daunting, at first. But, you can ease your wait into it by using Av (or Tv) mode to see what settings the camera would pick and use those as a starting point.
Using Av mode, set a "middle" Av of 4.5, compose a picture and half-press the shutter. The S3 will show you, in white numbers at the bottom of the EVF/LCD what shutter speed it will use (let's say 1/1000 for a fairly bright day).
Now, switch to M on the dial and use the left-right axis of the omni-button to adjust the shutter speed to the same number the camera picked (1/1000 in my example). And the up-down axis of the omni-button to adjust the aperture to 4.5 ... you should see that the exposure you set was exactly the same as the camera and the scene should come out identical.
Now, you can change the settings to see what effect they have on your exposure. Reducing the shutter speed will darken the scene and increasing the speed with lighten the scene. Opening the aperture will lighten the scene (and narrow the DOF) and closing the aperture will darken the scene (and widen the DOF). As you make adjustments, you can always "ask" the camera what it thinks of your settings by half-pressing the shutter. A number (-2 to +2) will be displayed in the EVF/LCD ... this is the number of stops away from what the camera would pick (the "standard" exposure) and what you've set. If the number is displayed in red, you're more than 2 stops away.
Take a series of pictures of the same scene gradually decreasing the shutter speed and then increasing the shutter speed to see how light or dark -2 to +2 stops actually is. Try the same thing lowering and raising the aperture.
Remember, each change of a full stop (whether aperture, shutter speed, or ISO) halves (or doubles) the amount of light hitting the sensor. You can get exactly the same exposure with a combination of settings. See how many different ways you can achieve a 0 exposure difference by adjusting all three settings; for example -- if you raise the ISO from 100 to 400, how much adjusting of the aperture and shutter speed do you need to do to get back to 0?
