If I remember correctly, the most difficult part of iterative deconvolution algorithms is knowing when to stop the iterations. If you iterate for too long, the noise gets amplified, and the image actually begins to look worse. I would certainly look at the image after each iteration.

The MaximDL website (a great image processing toolkit BTW) has a nice introduction to iterative deconvolution methods. --Wayne
