When I heard there is a solar eclipse coming in August, I decided it would be fun to try to photograph it. Knowing nothing about this type of photography, I did several days worth of web searches, and learned that it can be done, but it's possible to damage lenses and your camera sensor if you make a mistake and allow unfiltered sunlight to stream directly into your camera.
So, I took a chance and bought a Formatt- Hitech Firecrest filter, broke out the old Canon bridge camera, and headed out to the park for a test run. (Not quite ready to try this with the GX8 yet...)
The filter is specially made for solar photography, multi coated, with a rating of 18 stops , ND5.4.
Let me just say again, it's extremely important not to look directly at the sun without some sort of special protective optics, and trying this without special filters in place will damage your camera, and possibly your eyes.
That being said, here's my first two efforts. The filter made it incredibly difficult to focus, so I switched it manual focus and did my best. There is clearly a sunspot showing in the lower left corner.
Doing a little more research, I found that white balance adjustments can cut some of the glare. Here's one with the adjustments completed, really brings out the sunspot!
