Just thought I'd offer a quick reference for some standard aspect ratios for your renders. I only have the free version of TG2, so I'll reference them all from 800 pixels wide. Just lock the aspect ratio if you want to adjust the width for your own renders.

1.33:1 - 800 x 600 - (Standard 4:3 aspect ratio of television and internet monitors)

1.5:1 - 800 x 533 - (35 mm film, the aspect ratio of most photographs)

1.66:1 - 800 x 482 - (35 mm film, standard cinema screen size)

1.77:1 - 800 x 450 - (16 x 9 widescreen format of most DVDs)

2.35:1 - 800 x 340 - (Panavision or Cinemascope widescreen of the old time epics)

Note: the math for these calculations is as follows, if you want to figure out your own aspect ratios.

width x (1 / width_ratio) = height
800 x (1 / 2.35) = 340

Hope this is helpful. More information can be found here: http://en.wikipedia.org/wiki/Aspect_ratio_(image)#Previous_and_presently_used_aspect_ratios

Here's some important computer ones beyond 4:3.
http://en.wikipedia.org/wiki/Computer_display_standard

Many people now use 16:10 monitors (1.6 ratio)
Example 1.6's:
1440×900
1680×1050
1920×1200

most my renders i do are 1680x1050 or 1920x1200, as those are the resolutions I use, and then I can easily downsize and crop out to 1024x768.

Just to clarify on one of those from the original post ...

1.66:1 is not the 35mm aspect of most photographs as noted - this is perhaps an aspect ration of motion picture film based on 35mm stock.

1.5:1 is the ratio of 35mm still photography film stock - standard film size is actually 24mm x 36mm. This ratio has carried over to all DSLR digital cameras from the major manufacturers (Canon, Nikon, Sony, etc.)

The 1.5:1 ratio is listed 4th from the top in the wikipedia link posted ...

Thanks, Micheal. I'll make the change.
