Thanks Malcolm. I must say I am intrigued by the responses from Bill, Bob W, and Alan. Reminded me of a sub-section of a multivariate-analysis statistics course I took many decades ago. The issue was how to systematically identify underlying common themes in various responses to a set of stimuli and then to apply the results in a classification process. (For the biologists in the room, there is some overlap here with numerical taxonomy.) In a class exercise we got together in teams of 2-3 persons and tried to sort a handful of assorted nuts and bolts and nails and screws and washers etc. Some brass, some stainless steel, some small, some larger, etc. From all of this emerged an understanding of how to use one form of question to discern perceived dimensionality and the relative importance of different dimensions. Simply ask persons to look at a set of four objects and say which is the different one. I did NOT have that in mind when I posted the Family Portrait! But there are 4 cameras shown. Three from the film era, one digital. Three are relatively small, one is larger. Three are Pentax, one Leica. Three are SLR or DSLR, one is rangefinder. Three were sporting a 50mm lens, one with a 35mm. Bill, Bob W., and Alan all picked up on one or more of these differences but it is not clear which was the real defining difference they had in mind when making their comments. And I wonder if all three were reacting to the same aspect (I am guessing brand name) or if they were seeing different things. Just something to mull over while I am putting off the chore of getting the snow blower out from underneath the pile of tarps etc. in the back of the garage and clearing the driveway… stan -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
