Forgot to reset the flash and left it on slow synchro which motion blurred the shot. Almost threw it away but couldn't because my grandson's face is perfect and exuberant and my daughter's was in pretty good shape. After seeing the strength in thirds, I rotated and shifted the photo so that their faces would come out on the third lines. The I motioned blurred (why not they already were) every thing else to isolate them from the background. Rule broken: slow synchro flash leaves blur image. Why this works: he is just having too much fun for you to notice much else. Rule broken: tilt. Why this works: since they were already in motion the tilt helps out. Also the tile put both their faces on the thirds lines.
