Not sure exactly what ISO stands for, but it is the light sensitivity. Higher ISO means less light is needed to expose the film, or in the case of digital, less light is needed on the sensor. I am a bit surprised yours goes down to 50. Most common values are 100, 200, 400, and sometimes 800 or even 1600. As a rule of thumb, the lower the ISO the less grainy the picture, so if you are taking pictures outside on a sunny day I would recommend using an ISO of 100. I dont know about the sensor in your camera, but you can probably take great pictures with minimal graininess with ISO 400. I would use this for the time being, and see if you notice a loss in the picture quality.
Basically if you use ISO 50 the shutter has to stay open twice as long as if you use 100, 4X as long as 200 and 8X as long as 400.That is the difference between 1/30 (ISO 400) of a second and a full second (ISO 50).
EXP means exposure. It sounds like you can sent your camera to over expose or under expose your pictures up to two "stops." I generally under expose my full tank pictures1/3-1 stop, since the light is really strong, this helps avoid washed out (totally white from too much light) parts. A great time to use this function is when taking pictures of sunsets. Most cameras overexpose sunsets, which causes them to lose their colors.
I know you want point and shoot, and you have a great camera for it, but I would not discount photo shop. It is a great program. most everything you are doing could be done manually in the mast, but with tons more effort.
Here is a picture I took a few weeks ago:
Had I used the camera settings I would have had to choose to either wash out the sunset, but correctly expose the foreground, or correctly expose the sunset, and have the foreground be solid black. What I did was slightly under expose the foreground, then in photo shop I exposed the foreground a little more and reduced the exposure of the sky.
I also like having the control of resizing the pictures myself rather than relying on a program such as a hosting service to do it for me.
