An Garda

An Garda

A member of An Garda Síochána directed traffic in Blarney last night when Santa visited and the lights were turned on in the village.

This is a long exposure zoomed shot, of about one second duration with the flash firing at the end of the exposure.

To replicate:

  • Make sure you set your flash to “second curtain”. Use Google to find out how on your brand of flash. Normally the flash will fire at the start of an exposure.
  • Have the lens at it’s widest zoom.
  • Set the camera to one second exposure in shutter priority mode (Tv on Canon cameras, S on others) or use manual mode with an aperture as wide as possible.
  • Line up your subject, hit the shutter button and slowly zoom in.

If you’ve timed it right the flash will fire when you’re zoomed in right. They’ll be lit by the flash and any background lights will appear as streaks going towards them. It’s hard to get right and not overexpose your subject so keep practising!

Red Red Fruit

Red Red Fruit

Red fruit from a tree in the grounds of Blarney Castle. I have no idea what tree they come from as the name plate on the trunk is far below the wall where I photographed them.

I’ll update the post when I find out!

I found out that they’re called “Cornus kousa” thanks to Adam Whitburn who works in the gardens.

It’s Cornus kousa. Some people call it the Szechuan strawberry although it certainly doesn’t taste like one!

Happy Playing Music

Happy Playing Music

A man busking in Emmett Place, Cork a few weeks ago. I forgot to ask his name and he apologised for his playing as he was learning a new song so he was likely going to be strumming the same chords over and over again.

This was shot when I was out with Blarney Photography Club and it was shown at the next meeting. Another photo of him was shown too from a lower angle and closer which I think is better than this one, but this is the one I have so it’s all I’ll post!

Anyway, is it street photography if your subject is aware of you and looking straight at the camera? Before you answer, watch Bruce Gilden in action:

Coburg Street Lights

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.
