Saving an Old File—PureRAW Interpretation of a Lumix RAW file.

A while back, I learned that my Lumix LX3 files had been slightly cropped by the camera.

However, when processing these old files using DxO PureRAW, I discovered that, in addition to correcting various lens anomalies, the software reveals slightly more of the image captured by the camera’s sensor than was originally visible.

Below are two versions of the same photo of Irish Rail’s IWT Liner, exposed on August 28, 2014, at Clondalkin in suburban Dublin. The top image shows how the photo appeared out of the camera; the bottom is the result following PureRAW 4 conversion of the original RAW file to DNG format.

This provides a little more space at the bottom of the frame in what was an exceptionally tight composition.

The downside of the conversion is that the resulting file is nearly four times larger.

CR2 RAW file before conversion to DNG format. Note the extremely tight compostion with the locomotive pilot nearly touching the bottom of the image area.

This version offers a hair more track below the locomotive than visable on the original CR2 file. It’s not much, but it makes a difference!

A Moment of Sun Near Ballybrophy—2 slides.

It was a dull Friday afternoon in mid June 2005, when DH and I were exploring locations along the Cork Road (Dublin to Cork) between Mountrath, Co Laois and the top of Ballybrophy Bank.

We’d stopped in sight of the tracks on a lightly traveled dirt road, and were cleaning the car, when off to the east we heard the distant drumming of a class 071 in Run-8 (full throttle).

Irish Rail’s class 071s are mid-1970s era EMD diesel-electrics, built with Dash-2 technology and powered with 12-cylinder 645E3 (turbocharged) engine. Their sound is distinctive.

I grabbed my Nikon F3 loaded with Fujichrome Sensia II (100 ISO). As the Friday-only ‘Down Kerry’ (Dublin Heuston to Tralee) came into view, the sun peaked out from a thick overhead cloud-bank. Irish Rail 072 was driven by Irish Rail’s Ken Fox, who recognized us and gave a few friendly blasts of the hooter (horn).

As the train passed on its ascent toward Ballybrophy, the sound intensified—a characteristic of the doppler effect. We could hear the aged EMD until Ken shut off at the top of the bank—several miles distant.

I scanned these slides a couple of weeks ago.
