inphotos.org: Coburg Street Lights

§ November 27th, 2014

Coburg Street Lights

The lights of Coburg Street and passing cars in a long exposure shot of the street from the traffic lights at the junction with Bridge Street.

This was a 15 second exposure at f/22. The lovely star shape of the street lights is because the opening in the lens was so small (at f/22) and the diaphragms of my lens. It takes a long time to get the exposure but it’s worth it!

This appears to be a beautiful example of Fraunhofer diffraction. It is due to the wave nature of light. The effect depends on the wavelength (that is, the color). It is most pronounced when bright light from a practically infinite distance passes through narrow slits, causing the light to spread perpendicular to the slits. This spreads a point-like beam of light into a pair of streaks.

Using a small aperture creates slit-like situations at the corners formed by adjacent blades. Thus, when you have a combination of relatively intense, pointlike, monochromatic light sources in the image and a narrow aperture, you should see a streak (of the same color) emanating from the points in two directions perpendicular to the blades…

…Finally, length of exposure is related to the occurrence of this effect, as you have observed, but only because exposures with bright points of light are almost always made much longer than needed to record the lights: you’re trying to see the rest of the scene, which is much darker. The brightness of the diffraction streaks decreases so rapidly away from their sources that if you used a sufficiently short exposure to properly expose the lights themselves, the streaks would be practically invisible.

Light Trails on MacCurtain Street

Ghostly light from passing cars hangs in the air on the corner of MacCurtain Street and Bridge Street in Cork City, Ireland.

This is the second of three light trails or light streaks photos I’ll post here in an unintentional series of long exposure photos. The first was my Light Trails in Blarney photo published yesterday.

Light Trails in Blarney

The red lights of a passing car streak across this photo taken in front of Christy’s in Blarney over the weekend.

The photo was a long exposure of 8 seconds, at f/4, ISO 100. I was shooting in manual mode and made sure the scene was under exposed by at least a stop. As f/4 was my widest aperture the lens captured as much of the red light as it could.

I took numerous shots of this scene and was bent over my camera (with my wallet under the lens to angle it upwards) so long that a woman came over asking if I had lost anything!

Mallow Camera Club: Ten Distinctions for MCC Members

§ November 23rd, 2014

Saturday 22 November 2014 will go down in the annals of Mallow Camera Club as a red letter day.  No less than ten club members achieved IPF Distinctions, nine Licentiateships and one Associateship, at the final distinctions sitting of the year in Thurles, Co. Tipperary.

Teddy Sugrue was awarded his Associateship of the Irish Photographic Federation (AIPF), while Paul Tips, Noreen Murphy, Janusz Trzesicki, Michal Poplawski, Margaret O’Brien, Joy Buckley, Margaret McAuliffe, Anne Fuller Griffin and Michael Toner were all awarded Licentiateships of the Irish Photographic Federation (LIPF).

There has been a proactive mentoring programme in place in the club since the start of the year to enable members to hone their skills and achieve distinctions.  The success of members on the day was noted by the chairman of the adjudication panel Mark Sedgwick who said there was obvious teamwork in Mallow Camera Club.

The club hired a bus to transport members en masse to Thurles.  The bus made a stop on the return journey for a celebratory meal.  A long day – but an extremely successful and rewarding one.

Congratulations and well done to one and all.

All the successful panels will be on display at the club meeting tomorrow night, 24 November.  Come early – there’s sure to be some celebrating!

All Seeing Me: Angular

§ November 21st, 2014

Angular

So this weeks challenge is angular – let’s see if we can come up with an angle on this one.

I’ve a couple of shots for this topic, all of which were taken during some of my Urban Explorations of abandoned places. One of the advantages of using a full frame camera coupled with a wide angle lens is that you can really exaggerate normal angles and make them look more extreme. This counter in an abandoned Military Barracks is a good example.

An angular (en)counter…..

Even a simple corner becomes more angular with the wide angle. This shot is from an abandoned Mental Hospital.

Left or right?

Of course it’s not just straight edges that are angular as can be seen from these twisted rails at an abandoned Mine.

Let me know what you think of my angles…………….

Patrick Dinneen Photography: Grand Canal Dock Architecture Abstract

§ November 21st, 2014

I recently had a luxurious stay in The Marker Hotel, Grand Canal Dock in Dublin last weekend. The Grand Canal Dock has undergone major recent rejuvenation, now houses some exciting and eye-catching buildings, including The Marker Hotel and the Bord Gais Energy Theatre.

Both are very striking buildings and I was drawn to the lines and patterns in both. the first four photos are of the Bord Gais Energy Theatre (left)The last three photographs are of the side of the Bord Gais Energy Theatre, an (unknown to me) office building and The Marker Hotel, which has the black and white patchwork design.

The 96fm fugitive

The 96FM Fugitive is a character listeners of Cork radio station 96FM watch out for as DJs on the radio station give out clues as to his whereabouts. Find him and you’ll win a cash prize!

A few weeks ago they told people he was in Blarney and I was asked at least three times if I was the fugitive. OK, I hadn’t shaved that morning yet but did I really look that suspicious?

While out with Blarney Photography Club we stopped to make some photos of this striking yellow background with passers by in front. There were five of us there so we were hardly inconspicuous but people kindly ignored us! :)
