THE R VALUE FOR COVID19 REMAINS MYSTERIOUS
FIRSTLY WHAT IS THE R VALUE?R is the number of people that one infected person will pass on a virus or infection to, on average.AND IS a respected epidemiological statistic that helps to understand the infectivity of an illness and has been used for many decades to study illnesses such as measles where data is available on large populations
for covid19 however we do not have these data as it would require specific mass testing of a defined population repeated on a regular basis eventually this may be feasible if the plan to mass test a city like liverpool takes place
currently this R NUMBER is being used it seems by the government to determine severity of infection and to determinesubsequent actions such as lockdowns which are serious sequelae recognised to damage economies, lives, livelihoods and mental health yet we still do not know precisely how the R number is calculated but the various scientific groups in SAGE must use other endpoints as proxy numbers but we have yet to be told what they use this should not be a secret especially as the usual suspects such as case rates, hospital admissions and deaths can have many factors that influence them that i have covered in previous blogs (examples include more testing leading to more cases, more hospital beds allow more admissions,inacurrate counting of death rates
few of us are expert epidemiologists including matt hancock etc, but we are all affected by lockdowns, tier levels, travel corridors or whatever other soundbites the government emerges with and deserve to know the precise origins of the R NUMBER , which to me remains so mysterious as to be fictitious until we know how it is calculated especially also as it is reported as a range very often and a change in the number may lead to either a lockdown or escape from one
Ljubljana – the most beautiful city in Europe
Ljubljana is the capital city of Slovenia and is a city with the river Ljubljanica running through the city centre giving an intense backdrop to the many restaurants and cafes that line the river banks.
The city has a population of around 300,oo and that excludes the many dragons lining bridges and other areas. The dragon is the symbol of Slovenia.
It is an attractive lattice of cobbled streets, arched alleys and fine cultural monuments, many of which were bequeathed to the city by Jože Plečnik (1872–1957), Slovenia’s most celebrated urban planner including the brilliantly conceived Triple bridge.
There are plentiful museums as one might expect from a capital city but the real enjoyment comes from simply walking the streets and seeing this city first-hand. Oddly the castle which gives an almost fairy tale backdrop to the city is about the only average feature of the city .
Many of the streets are cobblestone and lined with street art. Small bakers and other artisans sell their wares.
The bars and restaurants are plentiful and provide ample choice, although maybe pizza is the commonest type of cuisine.
Never also forget the amazing street art that is everywhere.
You can sit literally in the river and eat and drink in various bars and restaurants
When nighttime comes there is often entertainment in Pleseren Square.
Cricket is A Photogenic Sport. How to Photograph a cricket match
Cricket is an under rated sport to photograph amongst photographers. There has long been a belief that 800mm lenses are essential. The reality is that cricket can be well photographed with 400mm focal length lens. Key basics include using shutter speeds of at least 1/1000th and shooting from varied vantage points around a ground. ISO speed is rarely an issue and speeds of 800 ISO and numerically higher are unlikely to give troublesome graininess as cricket is usually played in decent lighting conditions.
As for most sports fans of cricket will find it easier to photograph cricket and will appreciate the attributes of various players. For example those likely to play more attacking shots and those of a more passive nature. Each bowler has a different style and action. There are also many opportunities to photograph the people at the game and of course the ground itself. 
In general cricket is often an all-day game and thus it is impractical to photograph each delivery, so some selection of when to photograph is worth considering. The first couple of overs are often a time that wickets fall and the overs after a batsmen is out is another time when there is a higher percentage chance of getting good action shots.
The players often also mingle with the spectators at many grounds especially when leaving the pitch at lunch or teatime. 
A few hours somewhere in the Rome suburbs in early May
It is early May and the weather is surprisingly warm. I am somewhere in the Rome suburbs for a meeting this evening . This gives me the chance to just walk around for an hour or two.
First impressions are that few speak English and chaos reigns. Smoke is everywhere in the usual Latin way and folks amble along down the streets with no evidence of speed. The buildings are mostly old and not so well kept. Even some of the buildings give the impression of smoking with wisps of white cloud above them.
A few pizza restaurants are open along the main streets. But a pleasant place to stroll around in the sunshine. Avoiding the cars is the most important thing as they drive and park seemingly everywhere. Curiously I did see one car with what I imagined to be a parking ticket. It was the only car parked seemingly in a proper place! Cars parked on pedestrian crossings were not unusual
All the offices and houses have entry systems that look like they are some random game.
PHOTOGRAPHY AFTER A STROKE A FEW THOUGHTS
there does not seem to be much specific advice or comment even so I thought a few words might be interesting for those who find themselves in this unfortunate situation, luckily this is not a job for me but a fairly serious hobby where i try and take my photography to the quality of a professional
after the shock of a totally unexpected stroke i made my decision to fight and try to get back to my previous perceived level. the biggest challenge would be my sports photography in which the weight of the equipment’s going to be a clear challenge
chrisbushephotography.com
weight challenges– i bought a lighter camera body canon M50 and decided that i would have to use one of my lighter zoom lenses canon 75-300 which is a good lens but not of the standard of 70-200 2.8 or 100-400 and also bought a tamron 14-400
focusing as the stroke left me partially blind ,this required patience and after trying out live view i returned to using viewfinder out of preference another strategy was to take far more shots expecting but not liking the errors
movement being accustomed to moving around a lot this is the biggest challenge having to take all my photos from a wheelchair in one static position
the brain takes a little longer to fathom out the players to follow and potential action areas
but it is all coming together and i will get there while maybe learning new adaptive skills on the way
