wondering now about the WB on this....

Yes, that's a picnic table, and about half the snow is already gone from the top.

C&C welcome

Couple of pics on the other laptop, will go and process some more now.

focal squared / f x 0.02
that's it. It's not complex.
Example: 28mm lens, f8.
28 x 28 = 784
8 x 0.02 = 0.16
784 / 0.16 = 4900
Therefore: set focus to 2.5m and f8 on that 28mm SMC-M and leave it.
I've been working with this at work for video footage and it works pretty well. Everything really is reasonably in focus, too, and that to infinity.
To make it really easy and to give some reference points, here a quick excel table, working in mm at both f8 and f16. You can do the rest of the maths yourselves
Set focus to these distances and everything from within half of the distance to infinity will be acceptably in focus.

Behavioural analysis is the way forward, along with cloud capability and better UIs to inform users - they are getting into a lot of technology they don't understand and need their hands holding.

However, lots of things *are* possible....
I would definitely advise caution as far as allegations on-line are concerned - the courts are slowly catching up to the idea that stuff that happens online may represent real life.

In an oral statement, May says that police officers will not be able to use Section 44 stop-and-search powers on individuals. However, Section 44 will remain available to police officers wishing to search vehicles.
Talk to the BJP, maybe? Newspapers?

On the English language ones, it's to enable "gentlemen" to discuss without profanity being an issue and "glamour" is also not a problem.
On the German one, it's because it's a real club with fee-paying members and they get something for their money.
"by application only" and after a while of being on the board are common entry requirements.
