Yes, of course, Photoshop is good for photos, I did that alot many years ago. I was working for a big company on Photoshop 5.0-5.5, then started on 6.0, but then left to become a fulltime DP.
I hadn't had any experience on Illustrator, but logos are what I'm learning now.
What about just normal text, since I mainly used Title Tool in Premiere ??
Since I just starting on Illustrator, I'm wondering, from what others have seen,
what the best purpose of Illustrator should be ?
