Unexpected pinhole effect

21 July, 2009

You could set a pinhole up to project the eclipse onto a makeshift screen but really, the pinhole camera essentially works with any tiny hole that can serve as an aperture.

One effect to look out for is the pinhole effect when sunlight filters through any tiny gaps, including those in trees in between leaves.

This could be anything from tiny gaps in between the leaves in a tree,

Watch out for the ad hoc and unexpected pinhole effects around you next Wednesday during the eclipse. It might create a pretty sight that is as rare as the eclipse itself.

Less than 24 hours to go!

DIY solar filters for camera

20 July, 2009

From our earlier post on the topic, here is how we made our solar filter holders for some of our cameras.

Plastic bottleFirst we got plastic soya sauce or pepper bottles from the local sundries store. The kind you find in kopitiams or the local coffee shops.

They’re made of soft plastic, so they’re easy to cut up with scissors.

To start, we cut a hole in the bottom, and cut off the edge of the top as well.

For our filters, we exposed a roll of black-and-white film to light and got that developed it. The silver nitrates in the film will serve as the protective filter for the camera.

Cut two layers of the developed film together and glue them down to the plastic holder.

And voilà — protective filters for your camera.

Secure this to your camera with tape. Works great for digital cameras and handicams.

Then Eclipse vs Now Eclipse

20 July, 2009

Here’s a picture of the total solar eclipse of 1900 taken from USA.

To capture this image, scientists loaded several railroad cars with scientific equipment and travelled from Washington D.C. to Wadesboro in North Carolina, where they had calculated would be the best location in North America for viewing this total solar eclipse.

Called the Smithsonian Solar Eclipse Expedition, they hoped to record photographic proof of the solar corona for further study.

The team included Smithsonian photographer Thomas Smillie, who headed up the missions photographic component. Smillie rigged cameras to seven telescopes and successfully made eight glass-plate negatives, ranging in size from eleven by fourteen inches to thirty by thirty inches. At the time, Smillies work was considered an amazing photographic and scientific achievement.

Today, besides powerful radars on ground, we have satellites orbiting in space specially to study the Sun, such as SOHO (SOlar and Heliospehric Observatory) and STEREO (Solar TErrestrial Relations Observatory), just to name a couple.

As for capturing eclipses, besides the sophisticated equipment of professional astrophotographers, solar eclipse buffs and media crew, we have digital cameras and handicams.

Thousands and thousands of them will surely be pointed to the sky come Wednesday morning.

One event, three views

2 July, 2009

Three amazing views of the same eclipse on August 1, 2008. The three views were shot at different places in Russia. Top to bottom: Novosibirsk, Miensk and Moscow.

Will you be able to see the solar eclipse of the century this July 22?
