Hi Pam, >I was not aware that the JPEG files....loses bits....< Yes, after I purchased my Mustek scanner a few years ago, I quickly learned that a little definition is lost each time a .jpg file is loaded and saved. There is another disadvantage to .jpg files. If native-formatted files are saved as .jpg files, all of the layers are merged into a single layer. For that reason, I always keep one version of a given photograph in the native format (.psd for PhotoShop). NHP

data loss in Jpeg: well said Daniel! the article stated that... --------excerpt from wsj article----------- "But there's a difference in quality over time between JPEG -- which is known as a "lossy" format because it discards, and thus loses, some data each time an image is opened on your computer and then recompressed as it is closed -- and formats like TIFF (for Tagged Image File Format) and RAW (as in unprocessed), which preserve all the image data." ----------------snip------------ Yes, if an image is opened for viewing and then recompressed when closing it may lose information/quality (depending on the Jpeg settings) I never close the image saving it unless i made some modifications... so, it's not an issue... p.s. i think i'll start shooting RAW to differentiate from the masses and act like a PRO.... ;-) How much flash do i need then??
