Getty's technical requirements seem to vary by what sort of category your images fall into:

- Photography - Creative/Advertising
- Photography - News, Sport and Entertainment
- Photography - Archival
- Video
For 'Creative/Advertising', all they say of their technical requirements is:
Quote: • For 35mm digital capture, we strongly recommend use of a professional-quality digital SLR using RAW or uncompressed TIFF format. Most compact "point-and-shoot" and consumer-level cameras do not produce images of the level of quality our customers demand, and would not be suitable for submission.

Which seems rather flexible - basically if you have a cam that can do RAW, you might be in. In this image category I think they place more emphasis on the image idea rather than the image quality:
Quote: 1. What type of images are we looking for?
Highly conceptual – it could be used to communicate more than one message.
Strong composition – and good lighting.
Generic appeal – it could be used to sell more than one product or service.
For the 'Archive' category there do not seem to be any technical requirements, which I guess makes some sense, given that they are after older images.
For 'News, Sports and Entertainment', it seems to be harder to nail down exactly what their technical requirements are, but the main thing is that they seem to want to see some online examples of your work, and in doing so identify if you can give them images of a quality they can use:
Quote: "If you are interested in becoming an editorial contributor you will first need to establish a relationship with Getty Images Editorial Division by submitting your News, Sport or Entertainment photography images to us via email at:
EditorialSubmissions@gettyimages.com
If you are a working photojournalist please provide tear sheets, professional references and links to view your work on-line, please email them to the same address listed above.
Please do not send jpeg samples. http://contributors.gettyimages.com/workwithus/ArticleView.aspx?article_id=1105
Getty deserve a prize, I think, for making basic information like this so confusing and hard to find.
