Couldn't think of a better title ;)

Two book comments, really one question and one comment.

1. On page 111, Fig 3.44, you mention a Measure Tool utility than can be had from a demo download of ProfileMaker. Not being familiar with that program, I googled it, went to the GretagMacbeth website and found no mention of any demo version. Is it still available? Is there a better place to look? Was I in the right place at all?

2. On page 127, "Size Does Matter." I have no contest with the premise of the article; I support it wholeheartedly. That's why I bought a Hasselblad, after using Nikons for years - to get better quality film-based large prints. My concern is with some implications in the information that you present. Everything you say is quite true; the way you say it is somewhat misleading. The vast majority of DSLRs are APS size and not FF; the vast majority of point-and-shoot cameras have sensors that are considerably smaller than APS size. Since your book is aimed at advanced photographers, as well as intermediates, I think it's safe to say that we all know who the only manufacturer of FF DSLRs currently is, and they only make two models of it, and not their latest and greatest Pro model. Their cameras are famous for low noise at higher ISOs. However, their total "blow-everyone-else-out-of-the-water" picture quality is not universal. Type of subject, distance to subject, picture color interpretation, and lens/sensor coverage issues all enter into the final equation. Suffice it to say, larger photo sities and the same megapixel count on a larger sensor will, theoretically, produce better quality files. I think that it is a mistake to get involved in any product manufacturer wars. It has the potential to turn off some readers over something that really has no significant bearing on what you are trying to cover in your excellent book, and could impact on your credibility. Your coverage, so far, of Epson vs. HP vs. Canon printers is quite even handed and seemingly factual.

As you might note from my previous post, I am reading through the book front to back. There are tidbits along the way that are immediately applicable to projects underway, and I'll put the book aside while I master a particular piece of info. It is not my intention to do an intensive critique of your work, but this forum is a great vehicle to discuss questions that arise. It's an excellent resource to combine with the text - well done.

I will also confess that the financial implications of implementing your complete workflow are staggering to me, personally. But there are many ideas, that even partially implemented, can reap vast improvement in my output.

Al,
I appreciate your comments and feedback. I'm always curious to know what others think.

When you download and install ProfileMaker Pro there will be an app in the folder called Measure Tool. That's what you're looking for. You launch it and it runs in demo mode unless you've bought the software.

You're of course correct in that many factors contribue to final picture quality. The intent of that section was not to shill for Canon (like they need my help) which is why I didn't mention them by name. Plus, for all I know aFF DSLR from a competitor could be just around the corner. To keep the comparison simple I chose two film sizes, 35mm and APS that would be familiar to most photographers. I felt readers could then also extrapolate the premise of photon-collecting properties of larger photosites to the MF backs which I didn't mention at all. Always a tough balance between keeping things concise and readable on the one hand and acknowledging all the minutiae that us geeks live for ;). But thanks for the thorough reading of the book. Nice to know it's not being used as a paper weight.

Thank you for your response; I understand now.

"... for all I know aFF DSLR from a competitor could be just around the corner."

From your pen to Nikon's ear! (the rumor mill says this August, but ...) Then again, as you pointed out in the previous book paragraph, it's really all about not trying to overprint your file - just like in the film days.

"Nice to know it's not being used as a paper weight."

I hadn't thought of that ... hmm ... ;)
