There are a couple of *HDR images where I moved the camera (I had pushed the shutter by accident and auto-backup had scoped up everything before I deleted these duds). My biggest disappointment is with stitched panoramas, which have very seldom worked for overlapping sequences I have shoot, Often they are jumpy *motion gifs, sometime they are weird *erase images. Also *erase seems to have a pretty consistent habit of liking to remove the subject or cut them into fragments. And don't get me started on *snow, I even have it covering my sketches now.
Anyway (other than in this post) I don't have to share these mishaps. Part of my Week of AutoAwesomesness
