Homemade Camera Sun Filter by Ronald Horii
This is the right way to take a picture of the solar eclipse. Get a filter like one of these: https://www.bhphotovideo.com/c/buy/solar-photography-filters/ci/34576/N/3537148334
Lacking that, I kludged up my own filter from 2 3D movie glasses. I broke the glasses to remove the filters. I sandwiched them back-to-back and rotated them 90 degrees. It doesn't work if you sandwich them front-to-back. One pair is not enough. I had to use two pairs. Because these do not block UV light, I also used a UV filter. Here are the results.
I wouldn't use this rig for continuous shooting. It would be more like aim, shoot quickly, put the camera down.
Alternatively, if you have a pair of ISO-compliant sun-viewing glasses, you could shoot through them. Good luck finding a pair. https://www.amazon.com/Solar-Eclipse-Glasses-Certified-Astronaut/dp/B06XPT2LL3/ref=sr_1_7?s=electronics&ie=UTF8&qid=1503079759&sr=1-7&keywords=eclipse+glasses
Better yet, this is the safest and cheapest way to view the eclipse: https://www.jpl.nasa.gov/edu/learn/project/how-to-make-a-pinhole-camera/

I have some totally exposed 1950s 50mm negative, but a pinhole's ok for me.

Note that stacking camera polarizing filters by screwing one on top of the other does not work. The reason is that camera polarizers are typically a linear polarizer in front sandwiched with a circular polarizer in back. The circular polarizer cancels the polarizing effect so the light comes out unpolarized. You can make it work by taping the camera filters together front-to-front so the two linear filters sides are next to each other. The 3D glasses are the same, except in the opposite order, which is why you have to stack them back-to-back. One pair of filters may not be enough. You may have to stack two pairs. Vignetting would be severe, so it wouldn't work with a wide angle lens.
Whatever you do, don't leave the camera aimed at the sun without a filter, even for a few seconds. You could burn a hole in your camera's sensor.
All of this is kludgey and somewhat risky. Even using ND filters is risky. The right way to do it is to use a special sun filter, as explained here. http://

Don't risk your sight to something you've MacGyvered together. Make a pinhole projector, and take pictures of the screen. Perfectly safe.
