• JPEG (common for print or web)

JPEG is an abbreviation of Joint Photographic Experts Group. Both Macintosh and Windows applications support JPEG. When used on a PC running Windows, JPEG files have the three-character extension: .JPG

• GIF (common for web)

GIF is an abbreviation for Graphics Interchange Format which is commonly pronounced "jiff" or "giff." GIF has become the file format of choice for online services including World Wide Web pages on the Internet. GIF is supported by both Macintosh and Windows systems and applications. When used on a PC running Windows, GIF files have the three-character extension: .GIF

• EPS (common for printing)

EPS is an abbreviation for Encapsulated PostScript and was developed by Adobe® as one of the file formats in its page description language, PostScript. It is a vector format (not bitmap), thus inherently scalable and moderately device independent, which moves easily across PC and Mac platforms.

Re: maybe a dumb question but need some help

Most TIFF formats use a lossless compression and JPEG uses a lossy compression. This means that you lose some picture information (quality) with JPEG and not with TIFF. Every time you save a JPEG file some quality is lost, this doesn't happen with TIFF images. A TIFF image is closer to what the camera actually "sees" and is good if you are going to do a lot of editing. The flip side is that TIFF images are much larger than the JPEG images. On my 5 MP camera with a 1 gig card, (19 pics already on the camera) I can get 388 high quality JPEG pics or 60 TIFF pics.

I myself can't tell enough of a difference between them to bother with the large TIFF filesizes most of the time. Perhaps if you were printing larger pictures or something like that, but TIFF images are probably not worth it for posting on the net.

Re: maybe a dumb question but need some help

Great explanation there. Got the option to take pics on my dslr in raw formats, but have never used them yet. With the RAW data format a pic that taken in the extra fine resolution setting that would be about 5.9 mb's, would be about 8.8 mb's in the RAW setting. From what I understand the color reproduction taken in these setting are far superior to the extra fine, but you have to edit those pics with the right software.
