    Perspective lines outside canvas?

    I saw a video tut where some guy used perspective lines that went outside the canvas. He could edit the lines at will; Move the lines and define their length whenever he wanted.
    How do I do this in PS CS?

    I think I found out how to do it. Pen tool seems to do the things i need it to do --but I can't make the pen lines stay on a layer that I can 'Hide'. Help :o

    Go into the Paths palette, create a new Path, and draw all your persp lines on that path "layer" using the Pen tool. You can use a standard guide for the horizon (the snap helps), and when you want to hide the persp lines, just deselect that path. Multiple persp layouts can go on multiple paths.

    if you want to actually draw the paths on a "graphics" layer, create a new layer, select the paths you want to draw, and use "Stroke Path/Stroke Subpath(s)" from the Path palette menu.

    Here's an example:
    Perspective lines outside canvas?

    For this pic I actually used three separate horizon lines due to the curvature of the "floor plane" (only two are shown), but it illustrates how the paths can be set up.

    To access all the endpoints of the persp line paths, use the "Screen mode with menu bar" option in the Tools palette (marked on the example, or cycle to it with the F key).

    I saw this method of making perspective lines in Gnomon: Scott Robertson - Creating unique enviroments.
    He also duplicated the path layer. Then used - Edit>Transform path>Flip Horizontal and copied (Copy&Paste) the result into main of path layer. This way he quickly made two point perspective.

    Yep, and you don't even have to dupe the path layer, you can just select the entire path or subpaths, copy, paste and transform/flip.

    Paths are really versatile for so many things, I just wish you could edit them as freely as with Illustrator. For more complex perspective, where I want it to be very accurate and technically sound (as opposed to eyeballed), I sometimes do the entire persp layout in Illustrator, then copy and paste the paths from there to a Paths layer in Photoshop. Best of both worlds (vector & raster)!
