If you choose to shoot with the 4:3 aspect ratio then you will have an
image which corresponds to the new international print size of 6 x 4.5
inch (150 x 114 mm) or the 8 x 6 inch (203 x 152 mm) print size.
All other sizes will again requiring some image cropping to fit the standard
frames

With the rapid growth of HDTV which has the wide screen 16:9 format a
lot more consumer products have adopted this display format such as
laptop and tablet PCs, mobile phones and digital print frames. If you are
shooting images that will be displayed on any of these devices it makes
perfect sense to shoot in the 16:9 HD aspect ratio as what you see on the
rear LCD screen of the camera is what you will see on this viewing
platform. There will be no image cropping.
If you were to display any of the other format images on the HD platform
you will notice that there will be some image border. Most TV systems will
scale the picture to fit the height so you will have grey or black side
borders and if you are making a HD video using these non 16:9 aspect
ratio images you will again have side borders unless you crop into the
image to fill the width of the frame.
