8 May 2016  Sunday  HANGZHOU

Today was the day for my presentation of 160 or so slides that have been the focus of my life for these past many months, as I have been exploring the vagaries of Photoshop and learning what is possible when photos are muddy and faded and over a hundred years old. With lots of help from my photographer friend, Cornelius Matteo, the photos look very good. Once the photos were enhanced, I listed them in the  order in which they were to appear during my talk, numbering them. 

I have a MAC, and as I added photos into categories already set up, I would add a letter after the number: Slide 10, Slide 10A, Slide 10B, etc. A very convenient way to do things. Otherwise, I would have to change 10A  to 11 and 10B to 12 and then change all the.subsequent numbers. 

And so this is just a bit of information for those who might have to move their disk with its 160 numbered slides from a Mac and use another (just a little inferior) computer. When you attempt to project the sides that have letters after the numbers and you are on one of those other (sorry, really stupid) computers, the other computers simply ignore those slides numbered with a letter after the number. You are preparing to talk about 160 slides, and instead ou are talking about 80. It rather destroys the flow of your talk and certainly eliminates a great deal of information. 

This is what happened to me wen I stood up in front of the assemble group and began discussing the photos taken by Clarence James and Sidney David Gamble. Months of work vanished. Very embarrassing. My presentation was rescheduled for later in the day, while I attempted to renumber 160 slides, Then, thank goodness, we found that when using a Dell, the sides with numbers and letted would at least appear, though in a strange  inverted order. Never mind. At least, they appeared.   

So for all you techies out there and for all you Mac-lovers, keep this in mind if you have to present numbered slides using some retrograde other machine.
