Using filters to photograph a solar eclipse - HELP!

posted November 12th, 2012

I took this practise shot this morning - not really overjoyed with it, although I guess it will do the trick to capture the eclipse on Wednesday morning (88% partial eclipse here). I've experimented with some of the settings I've seen other use for ISO / exposure / aperture + 8-stop ND filter (highest I have) ....

If anyone has some tips for me to use in capturing the partial solar eclipse, I'd really appreciate it.

I actually shot a solar eclipse using replacement lenses for welders goggles...worked out quite well. I put two lenses together and held them in front of the camera lens. perfect protection for your eyes and camera sensors.

I havnt done it but I would assume something like:

ISO 100
F22 or greater
Shutter speed as fast as you can go.
NDF

@tjs_world_part_2 Now that you mention it, I have heard that also.

@tjs_world_part_2 Yes- I did try the helmet ... no luck there.
@agima those were the settings I started with ISO = 100; speed - 1/4000 (fast as 400D goes) and F32 (high as it goes).
Got some detail in a few other shots I took like this one:

I used a variety of filters stacked to take this eclipse photo, as well as the transit of Venus.





I had two ND filters (2 & 4), two polarized filters (the ones you can rotate for various shades of opacity) and a piece of #12 welders glass.

ISO100 f/32 1/4000th

you could get a Lee filter Big stopper, but thats pretty expensive - but it increases exposure time by 10 stops

You can get proper solar eclipse filters. They're much darker than NDs.

@corymbia I went and got that variable ND filter today... then got home and found it was the wrong size :-(

@saranna Noooooo. I am having success with the variable filter. Picking up quite a bit of detail in the sun and think I have my camera settings OK ... but of course will have to experiment as the moon moves across.
