Solar Eclipse Photography
The 2006 Solar Eclipse
Back in 2006 , during the month of March, I was spending my vacation in Cairo and it happened to coincide with a total Solar Eclipse that passed through the far western edges of Egypt. In Cairo it was a partial one.
At that time I used to own a small point and shoot Nikon COOLPIX L1.
All I knew at that time is that you will get blind if you looked directly at the sun during the eclipse.
this thick black cloud passed by and acted as a Neutral Density Filter and made my day.

Safety Concerns when Viewing a Solar Eclipse
Before talking about how to photograph a solar eclipse, lets please increase the awareness of the dangers of doing it.
Never look directly at the Sun with your eyes, especially through an optical viewfinder, You surely do not want to end up with eclipse blindness. Looking at the Sun through a viewfinder, telescope or binoculars without proper considerations (solar eclipse glasses , solar filters) will result in loss of vision – it will literally burn your retina!
What is a solar eclipse?
The apparent size of both the moon and the Sun is almost the same as seen from Earth's sky , this is because the ratio between the Sun's size and the moon size is almost identical to the ratio between their distances to earth..... Coincidence ? ... no it is not.
A Solar Eclipse happens when Sun, Moon and Earth line up with the moon in the middle.
· Types of Solar Eclipse:
And since the moon orbit around the earth is elliptical , sometimes it is a bit closer (super moon) and sometimes it is a bit farther. this difference in distance creates a Total Eclipse or Annular Eclipse.
There are also Partial eclipses where either the line up is not perfect , or the location you are watching the eclipse from is not in the path of totality or annularity.
Further information about the Annular eclipse can be found here
Phases of the Annular Solar Eclipse
Planning the Solar Eclipse
o Awareness of astronomical events and continuous follow up.
o Calendar of eclipses according to your location : time and date
o Path and locations for eclipse / timings and durations.
o Applications and websites to be used
Shooting the Solar Eclipse
Precautions and considerations
Equipment, filters , tools and accessories to be used
1. Set your camera to Manual Mode
2. Use the Camera Live View Screen mode
3. Switch off Vibration reduction / Image stabilization modes in both the lens and the Camera
4. Activate the exposure delay mode or enable electronic shutter.
5. Use a remote shutter / intervalometer.
6. Set ISO to Lowest Native ISO (64 or 100) depending on your Camera & make sure the Auto ISO is off
7. Start with an Aperture value of f/5.6 - f/8
8. The Exposure setting is the tricky part :
a. Your shutter speed will vary greatly depending on what phase of the solar eclipse you are capturing and what time of the day the eclipse is happening.
b. If the Eclipse is happening at sunrise times , you will be able to start shooting for a limited time without filters ( like any conventional sunrise/sunset / Golden hour settings) , however when the sun altitude start to increase put on the 5.0 Solar ND (16.5 Stops) filter and use the following settings as an approximate guide line :
