I have a pdf of some math symbols and equations that I would like to age, rotate, and tilt in such a way that it looks like you're looking at an old open math book from an angle and you are seeing the symbols/equations on a page. I want the "page of the book" to look a little yellowed and antiquarian. All this for a LinkedIn banner.
Is Illustrator the right application? If so, is there a step-by-step tutorial or anything on accomplishing this? Maybe one tutorial for the coloring/aging and another for the roating/tilting?
The rotating/shifting can be done in Illustrator. See the documentation about how to transform objects.
The old pages is more of a Photoshop job.
So Illustrator first, then Photoshop?
Aging can be made by using the math stuff as a Clipping Mask or Opacity Mask over a worn/grungy background, and you can have a full (locked) background to look like the old paper itself, maybe simply (based on) a photograph.
Concerning the view from an angle you may very well get away with a simple solution where you create a(n unskewed) straight on version of the book (with a bounding rectangle) containing the (undistorted) math stuff everything forming a Group, and then create a skewed/distorted version of the rectangle (with just four corner Anchor Points), then using Object>Envelope Distort>Make with Top Object.
Illustrator is a vector program and usually your file choice for your typography & logos. Weathered looks & photographs are better done in Photoshop. Drop shadows can be done in both, But I feel Photoshop has a more accurate preview. Once you know both programs well you will have a better feel for how to use both programs sym=nergetically on your projects, but this is too long to explain in a post, and more of a chapter in a book.
That link is great starting point for the aged paper look! Thanks!
