I'm so impressed! For a thin little book "A Short Course in Nikon Coolpix 990 Photography" has proved to carry a WALLOP more information than any other book I've come across. While being a bit of a novice I grappled reading books (5 times thicker) on SLR photography just to get the concepts down that could help me understand my 990. This book made quick, neat work of the concepts that the other books often made confusing. Beyond that it gave me tons of information particular to the 990 I would NOT have found elsewhere, certainly not even in its' own owner's manual! GREAT job! --My only small reccomendation is in Version 2 of the book add a section on the underwater capabilities (using the proper watertight housing) the 990 has!
