Hi all who would like to comment. This is what I had gathered in class today about the 2 terms in the subject line.

JPG - is rastorized which guesses and does dithering which means gradually changing of colors. I have no idea what that has to do with anything yet.

GIF - is vectorized which is mathamatically generated. Fonts I think are vectorized in in a layer. Still I have no idea yet what this has to do with anything except photo editing somehow.

TIFF - MS product that is also vectorized.

raster:

Raster graphics have pixels....curves are not clean, and show the pixel edges.
They are bitmaps and very detailed and for fixing details by the pixel are
very perfectionistic and good for photo retouching. Making them smaller however, into a jpeg loses definition. Bitmap files are typically quite large.

Vector graphics have very clean edges...the pixels don't show.

Vectors can be enlarged or made smaller without much loss of detail.
And so vector files are best for fonts.

I find it very confusing too. You have to really work with them to see the differences.

There is something about the color densities too, I think raster has more. But don't quote me on that.

Thanks for the information. This does mean a lot and is very helpful.
