I have cropped a photograph to several aspect ratios common in film and video, with 35mm still as a comparison. I am by no means an expert, but created this to help myself see how different or similar different aspect ratios are. I am quite a fan of widescreen formats, but so far have been restricted by equipment to making videos in the 4:3 format, so I was interested to see exactly how much wider the widescreen formats are.
The image is a cropped down version of Volunteer tending fire in roundhut, Butser Prehistoric Farm, Hampshire.
'Standard' video (4:3)
35mm still (24x36mm)
Super16 (1.66:1) 
16:9 widescreen video
1.85:1 film (eg Super35)
Anamorphic and 70mm (2.35:1)
 NB: Super16 is normally cropped down to 1.85:1 for cinematic display or 16:9 for television use
