Ladder and Pole (Pladder?) Setup

Ladder and Pole (Pladder?) Setup

In order to get in the right location and the right Point of View, to take the Combat Air Museum panoramic photo, I put together this ladder / pole combination. It consists of a 12 foot stepladder with an 8 / 16 foot 'painter's pole' running up the center and passing through the small hole in the very top of the ladder. The bright orange object just above the fifth step is a Post Level used to make sure the pole is plumb and true.

In this photo, my D700 is mounted at the top of the pole using a Manfrotto 488RC2 ball head...and yes, my camera strap is clipped to the top of the pole as a safety measure..! The pole is extended here to about 15 feet so it extends some three feet above the top platform of the ladder. This allows me to stand on the last 'safe' step of the ladder and still be able to see and frame the shot using "LiveView" to make sure of my composition.

The base of the ladder is large enough to provide a lot of stability and also acts to keep the camera and pole in the correct alignment I use a radio release when I am taking shots with this so that I can maintain my balance and keep my hands away from the camera to eliminate any vibration. I do one button press to activate Live View, double check the image..and then a second press triggers the 7 bracketed shots.

This rig also will allow me to stand about half-way up the ladder and extend the painter's pole up another 10-12 feet while still feeling fairly (!) comfortable about having my gear close to 25 feet above ground..



big electrical pole and a lightpost/stoplight pole.

my scanner is crap so to get decent pictures from my 16mm microfilm escapades (110 reloads, submini/spy cameras) i have to actually use my enlarger. i'm still learning how to work it, but here's the first enlargement from my Minolta-16 P, using Copex microfilm.

the enlarger isn't designed for this small format, and won't go high enough on an 8x10 to fill the frame. also, i had to improvise a 16mm negative carrier by sandwiching the negative between two strips of 35mm film, with a rectangle cut out. works well! what you see is a black border where the mask rectangle is bigger than the image, followed by the rough edge of the rectangle cutout.

print was still wet when i put it on the scanner. this ain't perfect, but it's proof of concept. and i think this is a strong image too!

Technical Pro XTREME1501 Subwoofer, Black

The Xtreme1501 is a Carpeted 15 Inch Powered Subwoofer. This speaker is for anyone looking to beef up their low end and achieve a thunderous low frequency output from their speaker system. The Xtreme1501 has a total peak power of 1500 watts. This is the type of power you need for a large sized venue such as a live stage show, large studio space, showroom or in a nightclub. This subwoofer is an ACTIVE speaker which means you do not need any additional amplifier to power this speaker. The system comes complete with a satellite amplifier that can power two up to two additional loudspeakers. Use this amplifier to power additional satellite speakers orbiting the subwoofer. The inputs are 1/4 Inch and XLR. Connect any standard playback devices or mixer to this connection and send your source through one of the best subwoofers on the market. The passive pass-through outputs of the subwoofer are 1/4 Inch and XLR. Use these pass-through outputs to send the signal to another power subwoofer. Using the outputs of the satellite amplifier you can choose between two speakon and two banana connections. You can use these outputs to power two other satellite speakers. The woofer is 15 Inch with a massive 90ounce magnet and 3 Inch voice coil. This will deliver a clear translation of booming low end frequencies. There are separate volume controls for the subwoofer and the satellite speaker connections. This is key if you need to balance out your levels between the low frequencies coming out of the subwoofer and the mid/high frequencies coming out of the satellite speakers. Also inside you will find a switchable high pass filter for the satellite connections. If you are sending your whole signal into the subwoofer use the high pass filter.this will send the low frequencies to the booming subwoofer and the high frequencies will pass through to the mid/high satellite speakers. This is a professional set up meant to properly send your frequencies to the proper speakers.

  • UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from coming through. UV filters are used in sunscreens to protect skin or in photography to reduce haziness or fogginess created by ultraviolet light.

  • This is an Ultra Violet absorbing filter that helps overcome the abundance of blue in outdoor photographs. Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene.

  • This coating is a filter for the harmful UV radiation. The coating is either put on the lens or is imbedded into the lens to protect your eyes for the harmful effect of the sun’s UV radiation.

B+W 67mm Kaesemann Circular Polarizer with Multi-Resistant Coating

Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. The "high-end" polarizing foils of the Kasemann-type filters are neutral in color, they have a higher efficiency than conventional polarizing foils and they are cemented between high-grade plane-parallel optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plane-parallel surfaces. Subsequently they are edge-sealed to protect the foil against humidity. Discriminating photographers regard the B+W Kasemann-Type Polarizing Filter to be the very best of all polarizing filters. They are well suited for applications that require the highest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.

Christmas Reading & So Strange It Should be Fiction

Christmas Reading & So Strange It Should be Fiction

Cover art courtesy of Bloomsbury

In August I mentioned a New York Times review of the alleged next Harry
Potter book. Whilst waiting at London City Airport on Christmas Eve to
fly home to my family I managed to pick up a soft backedcopy of
Jonathan Strange and Mr Norrell by Susanna Clark which apparently is an
'airport exclusive'. Like the Potter series, this fantasy novel is
published by Bloomsbury and they have a successful product on their
hands. However the products are poles apart, Clark's work reminds me of
the intellectual rigour that you find in the Lord of the Rings as
Tolkein's background in old English literature shows through. Clarks
efforts are based on gaelic faerie tales, the Brothers Grimm,
Napoleonic history, the gentlemen of Dickensian and Kipling literature
and a love of the English language. Antique English is given a salute
with show and showed being substituted with shew and shewed

It is not a book for the faint-hearted weighing at almost 900 pages,
but is very well written and has a well paced story. It is not likely
to appeal to the Potter series younger audience but his adult fans,
they may be joined by graphic novel fans who would appreciate its
richness and depth. I think it is one of the cleverest novels since The
League of Extraordinary Gentlemen volume one and it has praise on the
back cover by Neil Gaiman, better known as the author behind the
Sandman series.

The second book that I read was The Forty Seven Ronin Story by John
Allyn. This is based on one of the most famous (and true) examples of
samurai honor and bravery. In 1702, Naganori Asano-Takuminokami was on
a ceremonial visit to the Shogun, he was insulted by a greedy and
corrupt courtier, Lord Asano struck the courtier with his sword,
violating the law, and resulting in his own order to commit ceremonial
suicide. His estates became forfeit to the Shogunate and all of his
retained samurai became ronin.

They plotted revenge and regaining their honour by killing the
courtier, 47 of the ronin bided their time, and struck back. Though
their devotion to Bushido impressed the entire nation, the Shogun had
no choice by to give them the most lenient sentence that he could -
committing ceremonial suicide.

It is a fantastic book with real depth and contextualises the culture
for a gaijin such as myself.

The Smoking Gun has alleged summary of evidence on what has been
uncovered in the Michael Jackson case here and it makes for disturbing
reading that is also strangely compelling, see for yourself here. By
their own admission this report is based on the review of documentation
provided by sources who allegedly had access to secretl police and
government reports, grand jury testimony, and sealed court records. It
may be true,or The Smoking Gun may have been hoaxed.

(Dates are approximate)

Gen 13
By Michael Vance

“Met Gen 13! These gen-active teenagers … were recruited into … a project secretly intended to develop superhumans. Upon discovering that the program was nothing more than a breeding ground for gen-actives, they escaped the compound … and to this day remain fugitives”.

Translations: this is another superhero team.

Last issue: Gen 13 is trapped on an alien spaceship. Having befriended a captured alien, they learn they are specimens. Experimentation on a Gen teammate causes a violent change and destructive rage. The damage to the vessel’s instruments causes an accident with another huge ship, and “the outlook is not good … “

Well, it’s not bad either. This comics title has a number of exceptional things that actually bode well for its future.

For instance, the edited introduction and last-issue summary in this issue of “Gen 13” (Topping this Suspended Animation column) are concise and needed for new readers. These are often missing from other comic books.

For instance, this issue’s story is tightly plotted and well-written, although not particularly original. It is also self-contained, albeit certainly part of a serial adventure. That is also often missing from other comic book titles.

Best of all, there is a light-hearted feeling of adventure here that ignores the angst of too many other comic books today.

Thanks for that, “Gen 13”. You’re too gen-erous.

I couldn’t resist.

However, the irritating Yoda dialog of one alien (“System severely damaged by collision, the captain says”) could easily be dumped.

Hurray! It is on the last page!!

Well boding also is the art.

Oops, now I’m Yoda!

Artist Al Rio is an ombudsman with a pseudo-realistic style that is visually easy to read, and dynamic. His uncluttered art is masterfully enhanced by its coloring, and by the unobtrusive placement of dialog balloons.

Say, not only is Gen’s outlook not “not good”, it’s downright fun!

“Gen 13” is recommended for young readers and as light entertainment for adults.

“Gen 13” #21/$1.95 and 22 pages, from Image Comics/Brandon Choi: story/available wherever comics are sold.

The Law of Tort - 2nd edition. General editor: Ken Oliphant. Butterworths Common Law Series

The Law of Tort - 2nd edition. General editor: Ken Oliphant. Butterworths Common Law Series


A review by Phillip Taylor MBE. Richmond Green Chambers.

Ken Oliphant has brought together his excellent team of ten for the common law title ‘Tort’, or ‘Torts’ as some prefer it, as the second in this series from Butterworths which sets a very high standard throughout its 1700 pages.

The work provides an in-depth analysis of the modern law of torts set out in 30 chapters with a user-friendly index and rather a lot of footnotes which is to be expected when identifying principles derived from judicial decisions and legislation where you must have the detail. Under Oliphant’s guidance the team has produced a worthy rival for its heavyweight competitors with each bringing its own gifts to the practitioner, judge, academic lawyer and student. So what makes this work different?


The style is different and very much a trademark of the Butterworths stable of books to start with, and what I would expect from Butterworths. It provides a clear and authoritative exposition of the existing law with each chapter very much the domain of the individual distinguished contributor.

The section headings are well chosen signposts as Sir Malcolm Pill describes them in his original Foreword, and both practitioners and students will benefit from the further thought and study suggestions contained here. I welcome, particularly, the sorts of issues which are likely to be raised by a set of facts which may be given to me by my client, and I now know where to look for possible solutions set out clearly and logically as great guidance.

I am glad Andrew Grubb clarifies these principles as ‘Torts Law’ for that is what it is within the common law as a series of civil responsibilities which go with rights. The waffling word ‘obligations’, which is the current favourite term to define ‘tort’ as a compartment, is something Oliphant tries valiantly to do on page one, as just about every writer has done in the past, and he makes a very good go at it.

I have always enjoyed the argument about whether we have ‘tortious liability’ favoured by ‘you know who’ and his other judicially unorthodox brothers of the recent past who were keen on creating certain types of equity to get the right judicial answer, or ‘specific torts’.

I think the ‘torts’ have it at the moment but who knows what might happen during the twenty-first century with the internet revolution and digitalisation. Let’s just say it is a civil liability and use the rights/responsibilities concept and reasonableness rather than the Euro word ‘proportionate’ which translates better (apparently).


This book is also useful for judges as it gives a degree of guidance on what the accepted view of the law is whilst thinking about a reformulation or change in the direction of the law deemed appropriate to its time – what Denning actually tried to do. So, if you are in court look around for the Butterworths series and you will know where his lordship is coming from!


Grubb, as series editor, succeeds with his stated legal direction for these great literary contributions to the modern statements of law from Butterworths, who are the natural historic leaders with Halsbury. Oliphant and his team have produced great assistance on understanding torts so that the law itself is “less likely to be left undeveloped ‘marching…in the rear limping a little’” which Grubb quotes from a famous judicial aphorism by Windeyer J in Mount Isa Mines v Pusey.

The signposts are up with this common law series, and practitioners can take the direction they want for their own practice- mine is clearly this signposted direction with its welcome contribution to the literature and the understanding of the law of torts- it has helped and encouraged me to identify potential developments in the law, and advice to clients, and I thank the distinguished contributors for sharing their knowledge and views with people like me who practice and teach the subject to the public.

Butterworth, Deal visit 2011 Manufacture of the Year

Butterworth, Deal visit 2011 Manufacture of the Year

ROCKMART, Ga., Oct. 5, 2011 – Major Gen. Jim Butterworth, Georgia’s Adjutant General, traveled today to this Northwest Georgia city with Gov. Nathan Deal and Chris Cumminskey, commissioner of the Georgia Department of Economic Development, to congratulate the employees at Meggitt Polymer and Composites for being named the 2011 Large Manufacturer of the Year by the Technical College System of Georgia and the Georgia Department of Economic Development.

Here, from the left, Butterworth, Deal and Cumminskie listen as Meggitt’s deputy president John Skubina explains how plant technicians use molds like this one for the engine intake of a Sikorsky CH-53 helicopter to make parts for that aircraft and many others during a tour of the company’s facilities.

Meggitt Polymer and Composites designs and develops aircraft seals, flexible fuel tanks and coatings, complex composite structures, smart ice protection systems and sub-assemblies, and interior panels and accessories for several civil and military, fixed and rotary wing aircraft, and military vehicles. Among them are the UH-72A Lakota, the UH-60 Black Hawk helicopter and the Humvee, all of which are used by the Georgia Army and Air Guard. According to company officials, Meggitt also has a large number of Georgia Guardsmen and Reservists among its more than 1,000 employees.

“On behalf of our more than 14,000 Citizen-Soldiers and Airman, it’s my pleasure to be here to honor this great group of men and women,” Butterworth said. “It’s because of their commitment to quality that we in the Guard, and all the services, are able to do our jobs, confident that the equipment we operate is the among the best in the world.”

During his address to his fellow employees, Skubina said Meggitt has always understood the importance of what the Guard does, and it is that understanding that continually drives the company toward the highest standards of quality.

“We appreciate what the National Guard and all the services do for us,” Skubina said. “As we continue to stand behind each and every product we manufacture, we will continue to stand behind those among us who leave our ranks to join yours when ever they get the call, however long they may be called to serve.”
