Hi Ian !
good going on the SD300 !, you just bought a top rated camera !
Image quality is amazing, and so is video mode.
Btw, do NOT forget to go into "manual" mode and "P" for so many groovy functions !
I shoot in "P" on my PowerShot G2 all the time.... in "P" mode I can choose ISO 50, - this creates the least grainy images,
and is really good for prints....
Make sure to ALWAYS shoot at the highest resolution on your camera. - that's a basic rule anyone worth their salt will tell ya.
If you don't shoot at the highest res, then you are not taking advantage of the camera's strengths.
Also make sure you are shooting in at least "fine" mode ( compression ) Extra fine is the highest the camera will go and some say they
can tell the difference but I can't . I shoot in fine mode as "extra fine" will cut the number of images by half on your sd card.
What else.... oh yeah "P" mode enables you to "FORCE" the flash.....
In auto mode, the camera will shoot the flash when it sees fit, and won't shoot the flash if it thinks there is enough light.
Shooting in "P" mode enables you to "force" the flash - push the button so you see the flash symbol stay on your camera LCD.... now you can
shoot in an area where it may be light, but you want to make absolutely sure the flash fires.
A great example of this is when you shoot somebody against s a window........ without forcing the flash, the camera will shoot the image
without flash, and then your subject is dark, because the camera has detected the light from the window, and is fooled..... so it doesn't fire the flash.
anyway blah blah blah. You have fun with your new camera !
