Cessna Birddog

The U.S. Army was searching for an aircraft that could adjust artillery fire, as well as perform liaison duties, and preferably be constructed of all metal, as the canvas covered Liaison aircraft used during World War II (primarily Stinson and Piper products) had a short service life. The US Army issued the specification for a two-seat liaison and observation monoplane and the Cessna Aircraft Company submitted the Cessna Model 305A, a development of the Cessna 170. The Cessna 305A was a single-engined, light-weight, strut-braced high-wing monoplane with a tailwheel landing gear. The greatest difference from the Cessna 170 was that the 305A only had two seats, in tandem configuration (the largest tandem-seat aircraft that Cessna ever produced), with angled side windows to improve ground observation. Other differences included a re-designed rear fuselage, providing a view directly to the rear (a feature later dubbed “Omni-View” and carried to Cessna single-engine aircraft after 1964), and transparent panels in the wings’ center-section (similar to those found on the Cessna 140 and the later Cessna 150 Aerobat model), which allowed the pilot to look directly overhead. A wider door was fitted to allow a stretcher to be loaded.

The Faces of Anzac Day 2011

Anzac Day is great day that never ceases to amaze me and fills me with a immense sense of respect for those left surviving from some of the crazy conflicts over the years.

For those in Sydney it was a cloudy and wet experience but the passion certainly was not damped out, it is always a great day and awesome when you can start to recongnise some of the old codgers every year. Its even better when new faces appear to carry on the memory of those who have passed on, whether it be from old age or through unfortunate circumstances in a conflict in another country.

As it has for a number of years, the rain came down repeatedly but was not too heavy to deter most supporters and marchers, there were certainly less photographers out this year compared with last (from my POV).

Anzac Spirit

A now non-existent piece of Graf over in Annadale

The Anzac spirit or Anzac legend is a concept which suggests that Australian and New Zealand soldiers possess shared characteristics, specifically the qualities those soldiers are believed to have shown on the battlefield in World War I. These qualities cluster around several ideas, including endurance, courage, ingenuity, good humour, larrikinism, and mateship. According to this concept, the soldiers are perceived to have been innocent and fit, stoical and laconic, irreverent in the face of authority, naturally egalitarian and disdainful of British class differences.

Progressive Sharpening Example

Remember there are different techniques for different situations

Here’s an example I often use, this is for progressive sharpening for web presentation – essentially program independent (however i use CNX2)

Step 1; resample image at a small size/resolution, typically 50% of the original.

Step 2: Sharpen using unsharp mask with the following values:
Radius 3
Intensity 15%

Step 3: Fit photo, basically to the final size 800×800 for typical web presentation.

Step 4: Sharpen using unsharp mask with the following values:
Radius 3
Intensity 25%

This basically takes care of the fine grain sharpening, now you can also add in another unsharp mask using a larger radius if the image is slightly (and only slightly) OOF, I find typically radius of 75-80 at no more than 7-10% can salvage well.

(note: the following image is pretty darn sharp anyway, however this is an example of progressive sharpening for the web)

below are the two images, the first is a nef file that was made to fit 775×800 then saved as jpeg at 84% quality, the second is the same nef with the steps outline above applied.

and a zoomed in version of the two to compare

and just for reference, crop from the nef file, no sharpening, either in camera or PP (other than what happens when converting to jpeg)
