Trolley 134c

A version of the snap at reference 1 which has come unstuck in a curious way, with the appearance of several wavy, more or less parallel bands across the image. Bands which have survived whatever it is that the blogger people do with the images they upload, my notion being, for some reason, that they do not store the raw image, as supplied. There is some compression going on. Maybe part of that reason is the fact that the raw image is 3.68Mb while what you get if you right click and save the image from the blog is 18.3Kb. About the same as what you get if you copy and paste chunks of blog into a Word document.

To my mind, evidence of the images being as much under the control of software as of hardware. What comes through the lens is only part of the story.
