A shot of a Great Blue Heron pulling a fish from the water at the fork of the Thames river here in London Ontario. I was surprised to see this fellow in such a busy place but he was intent on filling his stomach with fish and paid little attention to me or anyone else enjoying the park that day.
A great Blue Heron last summer slices through one of the tideflat channels at the Billy Frank Jr. Nisqually National Wildlife Refuge in Western Washington.
It took the working team less than the one hour which I needed to take the sunset photo, to get the wings off the ground to fix it at the top.
That's precision!
It was very interesting to watch.

This perfect one-point symmetry caught my eyes when transferring at the Zürich Hauptbahnhof.
I processed a balanced and a photographic HDR photo from a RAW exposure, merged them, carefully adjusted the color balance and curves, desaturated the image, and blended 50% of the red back in. I appreciate and welcome constructive feedback.

Precision Locomotive Leasing stores a collection of locomotives on the Shenandoah Valley Railroad's property. Recently, something no one expected came to pass. Buckingham Branch (another shortline that interchanges with SV) leased out a Western Maryland painted SD40 and for one day it ran on the lead of a test train on the SV. I, and many other photographers, did not pass up the chance to see a Western Maryland, C&O painted, and B&O painted locomotive trio together.
An Anna's Hummingbird feeding on a wild radish flower. If you look closely, you can see the pollen on the tip of its beak. It's easy to see how these little birds help pollinate plants. Check out its tiny little talons tucked away underneath too.
£500 Penalty for dumping rubbish, at the time I didn't notice the writing on the window.
Illicit rubbish dumping is out of control across the UK, perhaps our new Prime Minister could get the ball rolling on that one without making his rich friends even richer :-).

Female ruby-throated hummingbird refueling at bee balm in my garden. It is fascinating to watch these little birds as they hover and dart in any direction as they get lined up with the nectar source. The speed and precision in which they accomplish this feat is truly amazing. Backyard bird.
We miss a lot with the naked eye when wildlife does even routine things. I love the grace and elegance of this goose making a tip-toe landing in the golden tones of an early morning sun.
One of my attempts for the Macro Monday theme 'Tool'.
Again a theme that was a lot of fun to experiment with! The problem is that I can never really make up my mind which picture to choose for MM 🤔😄

Nikon D7200, Sigma 150-600mm Sports lens, 600mm, f/6.3, 1/1600, ISO 110. These tundra swans (and dozens of others) put on a precision flying air show, not quite up to the standards of the Thunderbirds or Blue Angels, but for big swans it was fun to watch.
Precision of thought is not the strength of poetic or mystical writing while at the same time experiential wisdom cannot always be confined to the wineskins of philosophical theology. The differences are not primarily in the content, nor even in the different historical contexts out of which the two visionaries speak, but in their language—the one best described as the language of the schools, and the other the language of mystical experience. Each one sees, but each one expresses it differently, not that what they see is so different, or the One whom they see, but that which makes one see his writings but as straw makes the other search for words that also fall short. Yet each acknowledges the plenitude, the fullness, the richness of Being.

Small, Green Violetear Hummingbird prepares to connect with this rather large trumpet-shaped flower. A fraction of a second later, it had its head and bill totally within the tube of the bloom.

Cylindrical Slide Rule.
When I was about fourteen I remember my maths master bringing in the first electronic calculator I had ever seen. It could do addition, multiplication, division and subtraction and had one memory. It cost around £300 in today’s money. By the end of my undergraduate studies I had a programmable scientific calculator that handled trig functions and statistics and cost only £30.
In the sixth form (i.e. years 12 & 13) we used slide rules and books of tables for calculation as calculators weren’t generally allowed in examinations. The slide rule I had was an advanced one, double-sided with trigonometric, log and exponential functions built in.
In many ways slide rules remain superior to calculators. They are fast, intuitive and less prone to errors of data entry. In experienced hands fairly complicated calculations can be done rapidly. They also make it easier to estimate answers and they teach you to handle the powers of ten in a calculation so that they become second nature. These skills become very important at university in a complex subject like Physics as you need to work out whether you are on the right track quickly when you are working a problem.
All slide rules work on the same principle. You can save doing a multiplication of two numbers by converting the numbers to their logarithms and then adding those together, finally converting back to ordinary numbers. In this way a multiplication becomes a simple addition which is way easier. Slide rules work by converting the log numbers into lengths on the rule and by sliding one bit of rule against another you can add the lengths (literally) and then read back the total length to convert back to the normal numbers.
The main drawback with slide rules is precision. An ordinary slide rule can work to about three significant digits whereas calculators work at eight or more. Of course precision doesn’t buy you much if you have entered the wrong figures into the calculator in the first place.
The precision is determined by the length of the slide rule: they’re normally about a foot long. Any longer and you have problems getting them in your briefcase :)
This is an image of my father’s precision slide rule. It gets around the length problem by spiralling the scale around a cylinder. The cylinder is in three parts that can rotate independently the scales on the top and bottom parts with a sliding sleeve in between. Collapsed down it is about six inches long, but the scale is equivalent to a slide rule about five and a half feet in length!
This is a picture of the top scale and part of the central sleeve, on top of some of the instructions for the device (an Otis King model “L” if you are a detailophile :) ).
I created this for the Macro Mondays Back In The Day theme this week. The exposed area of the scale is 1.3 inches so we are within the limits for the group - yey! Also for 7DWF :)
Thank you for taking time to look. I hope you enjoy the image! Happy Macro Mondays!!

Into Affinity Photo for some healing of dust spots; sharpened with a bit of Clarity filter and Unsharp Mask; slight, carefully constructed vignette to keep the highlights on the knurling top right, but to draw us in a bit. Then we’re done :)]
