> 2) Find a room in your house with a good clear wall and plenty of sunlight
> (like the living room)
> 3) Carefully tack your schematics on the wall at eye level.
> 4) Set camera on the tripod - turn off flash- set your zoom focal length
> to
> 55mm or better (not wide angle that causes distortion). Try to fill the
> frame completely with your subject.
> 5) Take the picture
> 6) Transfer the photo to your computer - crop and correct contrast using
> Picassa or your favorite photo editor
