Solar eclipse 2012

At the end of 2012 there was a solar total eclipse, visible from Bariloche during its partial phase. I took this series of pictures from the Bariloche Atomic Center, from the beginning of the eclipse until the Sun set behind the mountains around 20 minutes later.

All the pictures were taken at a focal length of 300mm, 1/8000s exposure time, aperture f/40, ISO 50, with a polarizer to reduce a bit the light (unfortunately I don't have a high density neutral filter, the Sun is still overexposed).

Note 1: The times in the last picture may be wrong by a couple of minutes, I didn't check the camera clock before starting.
Note 2: Looking directly to the Sun through a camera is dangerous both for your sight and the camera. Do not try to take pictures like this if you don't know what you're doing.

HDR Vista

This was the view from my office window on Friday morning. Not bad...

Update: This was the view 4 days latter...

She is Macuca. She is beautiful. She delivers happiness all around the house. She is a cotton pompom. She let me make her a photo session after her first bath...

At last! After a bit more than a year, this is the fourth and last delivery from the night photography course a did at Comunidad Cíclope. The location in this case was the beach at Bahía Serena.

The basic ideas involved are the same we'd used before at the Moreno Lake, the Cathedral, and the Casa de Piedra: long time exposures, movement, and light painting. Plus a final trick: circles of fire!

- I do. But I like to hear you say it.
- Love. You can learn all the math in the 'Verse, but you take a boat in the air that you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps her in the air when she oughta fall down, tells you she's hurtin' 'fore she keens. Makes her a home."
