What does illustrator do that Photoshop does not do?

[wookie1820]

I am new to adobe's suites. I was wondering if someone could inform me as to what Illustrator can do that Photoshop cannot.
Thanks

Primarily all levels of vector work.

Live (effects) or pre-rendered (filters) vector manipulation.

Raster graphics (bitmaps) can be used in Illustrator although the editing features for bitmaps are limited in comparison to Photoshop which is primarily (and to the same degree as Illustrator is to vectors) concerned with all levels of bitmap editing.

I learned graphics on software like Aldus SuperPaint and Photoshop. Since then I have been working with various vector applications, and much prefer to do all my layouts and logo designs, etc. in vector format. It's much easier to make changes, and re-sizing is not an issue.

Thanks Erixworx, my previous post missed the application of vectors to emphasise the difference.

*Two* questions though...

1) Does trapping in a *design program* affect the bitmaps or only vectors?

2) Furthermore, do software RIPs affect each pixel in the raster image when trapping? And to confirm: RIPs (unless I've just missed the whole point of PDF and PS level 3) only process raster images?

K i'm kind of new when it comes to illustrator, but i know photoshop pretty well. what are some things that illustrator would be better at then photoshop?

Answers (kinda)
1. Depends on the design program . . . most design programs have limited trapping abilities but most medium to large printers are using a good direct to plate system which includes very good final trapping of all objects on the page so you don't have to worry about it and the printer gets to set up traps to his preferences.

2. rips look at the intersections of the different colors and where there is not enough "common color" then they introduce a trap - I can't imagine where they would have any interaction with a photograph except along the edges where they would touch a color that isn't included in the photo

hope this helps

Thanks dabob...

Excelsi, I'd say its down to how you need to handle or manipulate objects. Illustrator would allow mathematically correct alterations: fills, outlines, overprints, type,
vignettes, accurate layering.
as opposed to the 'constrains' of bitmaps (pixels).
It was said earlier in this thread i think - and all these
changes would create small filesizes and scalability without
loss of detail provided you dont insert a dirty great bitmap
into the project.
