.jpgs and Image Resolution
Feb 22, 2011

We recently had our daughter's wedding shot using digital imaging. The individual files were exported to a DVD and range from 700kb to 3300kb, even though they were shot on a camera at 12Mpx. Depending upon the device used to display the images, particularly on an HDTV, they appear of low quality.

We emailed the photographer, who replied, "When I export jps I do so in a more manageable file size. Unless you plan to edit them further there is no need for larger files. The resolution does not get affected I can export a 12 megapixel file from 200k to 10mb. Either way it's still 12mgpx."

Is that correct? Doesn't seem to me that a 200kb file could provide the image resolution of a 10Mb file. While there may be good reasons why most people would want smaller files (storage, emailing, etc.), we're most interested in preserving high-quality images. Maybe I'm confusing concepts.

Thanks for the input.
