Hi Sheridan,
One of the things that you quickly have to gain as an author is a thick skin. Bad reviews are par for the course and, if you think that the criticism is unwarranted, the appropriate action is to send a letter of rebuttal and hope to get it published. I would welcome the return of fiery debate in the letters column of the JBAA as authors (often Patrick) slugged it out with reviewers. Perhaps the modern equivalent is this forum.
In this case I have not read the book and so cannot comment directly but David is one of our best imagers and he is well placed to provide a review. I certainly think that some of his criticism is valid (Graham’s views on the non-use of calibration frames in particular) so there are questions to answer. Let’s have the debate!
Nick.
