HDTV Photographs

Img_1010_sm

When I view my photographs through the Windows Media Center software, I especially enjoy the built-in pan and zoom effect.  But if my images are shot in 1600×1200 size they are not in the HDTV format.  While still good pictures, many cameras shoot in 4×3 aspect ratio.

For example (4×3 aspect ratio) 4 divided by 3 = 1.3333 and 1600 divided by 1200 = 1.3333

Try and see if your camera shoots in 16×9 aspect ratio.  My Canon A710 actually has a mode that says "Widescreen" and is 3072×1728.  This is correct for HDTV.

For example (16×9 aspect ratio) 16 divided by 9 = 1.7777 and 3072 divided by 1728 = 1.7777

So look for a size that divides into 1.7777 and you’ll know it’s 16×9 or HDTV.  FYI 1080p and 1080i are both 1920×1080 which divides into 1.7777
