To Restore or Not to Restore?

The first question I want to ask is, ``Why restore images at all?'' The reason for asking such an apparently ridiculous question is to emphasize that there are times when image restoration is not the magic potion that is needed. Most of the work that has gone on in my own group involves stellar photometry, and we have found that this is better done on the unrestored image than on any restoration. Specifically, we use PSF fitting by DAOPHOT. The trick is to have a good enough (and big enough) PSF - but discussion of that belongs to a different paper, at a different meeting.
