Hi from a newbie.

Just got the 300D (Black Jessops Kit) and a 75-300 USM [IS]

Very pleased with my first shots, however one thing confuses me.
Being new to D-SLR but not digital how come the image sizes are

I am used to 800x600, 1600x1200, 2048x1536 etc

The300D sizes are strange to me, 2048x1360 1536x1024

The full-frame 35-mm camera uses an aspect ratio of 3:2, and most dSLR's descended from 35-mm camera lineage (including all Canon EOS family dSLRs) follow that.

Many other digital cameras follow the 4:3 aspect ratio of conventional TV broadcast. Some offer the choice of both 3:2 and 4:3 aspect ratios.

dSLR cameras following the new Four-Thirds System will have an aspect ratio of 4:3.

The APS system offers a number of aspect ratios in its "delivery crops", one of which (format "C", for "classic") is nearly 3:2.

Best regards,
