I need to update all the "animation(!)" images on my website (www.animatedknots.com).     I have just purchased a Nikon D5000 and was hoping to use iStopMotion.  My initial tests suggest I am not on the right track.    I need between 5 and 15 images per "Knot".  Accurate localization of successive stages helps understanding the process.

What I wish to do is compose in "Live View" a moderately high resolution photo on the computer screen and be able to Onion Skin the next image.     

Any suggestions for software would be much would be appreciated.
