Many years ago I participated in an imaging conference in London, organised by the Royal Photographic Soc. Walking around in the evening, I found myself returning to Trafalgar Square with my camera. Here is a jigsaw puzzle based on, Trafalgar 1 (2006). I am looking along The Strand, and the building on the left is the South African High Commission. I like the blurred white delivery van in the foreground.

For all who need to navigate English. Recently I found myself hearing the term social distancing and thinking, ‘shouldn’t we be saying physical distancing?’ Not being an epidemiologist, but being an occasional technical writer, social distancing seemed to be an example of a trendy term for a well-established idea. I even went so far as to use ‘physical distancing’ in conversations.
Social Distancing vs. Social Distance
Social Distancing is an established term for the actions intended to stop or slow down the spread of contagious diseases. It is most effective when the infection can be transmitted via droplet contact, direct physical contact, indirect physical contact, etc.
So, keeping a good physical distance from others is recommended. However, I find no use of the term physical distancing. Not sure why.
How about social distance? Since social distancing is well established, one might be forgiven for thinking that social distance is what we want to achieve. Not so fast!
Social distance describes the ‘distance’ between different groups in society, such as social class, race/ethnicity, etc, particularly when groups mix less than members of the same group . In other words, it is the extent to which individuals or groups are removed from or excluded from participating in one another’s lives .
OK, that cleared that up for me. Let’s try to assure that social distancing does not lead to increased social distance between us.
The Decibel (dB) is a logarithmic way to describe a ratio with respect to a reference level. That part is easy. Now when it comes to expressing Signal-to-Noise Ratio (SNR), and particularly imaging SNR in dB, a couple of areas of confusion arise.
Next month Don Williams and I will be presenting a short course, Introduction to Color Management for Cultural Image Capture. This is part of a full short-course programme of the IS&T Archiving Conference in Lisbon.
Below is a (5 min) video about things we will be discussing. For those who do not have that much time a shorter (1.5 min) version is available here
