Any way to use a scan as a signature in Preview (Yosemite)?

I want to add my signature to PDFs in Preview, but the Trackpad/Camera method is terrible.

Any way to add a scanned signature to Preview??

The camera capture method works just fine, so long as you get the basics right.

• Write your signature in black on a sheet of clean white paper.
• Take your MacBook, camera etc over to the window, facing inwards.
• Hold paper, now in daylight, to camera.
• Done.

If the lighting is bad, the result will be bad.

sadly the only ways to add a signature in Preview, is by using the two different ways you mentioned. You could type your name in pages, print it out and use the camera.
