Well I'm not sure if this is really 'revolutionary' or not... but I just discovered this after messing around a little bit, and it saves hours and hours of work.
I have discovered a way to import paths from Photoshop into Illustrator. Why would I want to do that you ask? Simple. Check this out:
1. You open your high res raster image in Photoshop and also in Illustrator.
2. In Photoshop, use the wand tool to easily select any type of shapes you want in the original raster image. Mess with the Wand Tolerance at the top of the toolbar. Usually (depending on the image quality) I find that a value between 32-64 works good.
- Now you have a 'selection' that is almost exactly the same shape you would normally have made a path of in Illustrator right? If only we could get this into Illustrator...
3. Open the "Path Palette". At the bottom there is a button called "Make Work Path from Selection." Hold down the ALT key and click that button.
4. A dialog appears asking for a tolerance value. You can enter a value between 0.5 - 10 (in 0.1 value increments). The lower the value, the closer the resulting path will be to resemble the original shape of the selection. The higher the value, the less it will resemble it. It depends on how complicated a shape you have, but for me I found that a value between 0.6 - 1.0 worked the best. Feel free to experiment.
5. So now you have a path! Now lets get this into Illustrator! Press 'A' on the keyboard to choose the "Direct Selection Tool."
6. Click and drag a selection window around your ENTIRE path.
7. Now select and drag the path into the document you have open in Illustrator.
8. Give Illustrator a few seconds to import the path... and PRESTO! Your path is in! Now just line up the path with the background raster image you opened earlier.
Now this path is not perfect. It is most likely not as good as it would have looked if you would have originally drawn it yourself by hand. But this whole thing gets you literally 95% of the way there! Now all you have to do is go around the path, add or remove and tweek the spline handles to get the shape exactly how you want it. Boom! You are done!
I had this one long and very detailed path that took me 45 minutes to create and tweak. ... but this method only took 5 minutes or less....
Another nice thing about this method is that you can create tons of paths at once in Photoshop and import them all at the same time into Illustrator. This method I have discovered is saving me tens of hours on a special (and very detailed) sideart picture I'm working on.
Let me know what you guys think!
