    crop first, then resize to desired print size.  400 DPI recomended.
    Adjustments, levels, move the center Output slider up to wash out the color, .33 worked for mine
    Effects, Unsharp Mask:  30, 20, 6
    Effects, Photo, Sharpen, max it
    Effects, Stylize, Halftone: line, angle 0, adjust rest for effect
    save as jpg, high qiuality
    import to lasercad/raycam
    set BMP Engrave to speed 1000, power 20% (big laser), mode X_swing
    add your shapes for cutting border
    run in 2 sessions, engrave first, then cut later.
    set focus about 2mm higher than you normally would, run the engrave only.  
    set focus normal, taking care not to move the workpiece, run the cuts only.
