In Preperation for Sundays solar eclipse I have made a DIY solar filter for my DSLR and though I would share.
CAUTION If your going to take pictures of the sun with a DIY solar filter I highly recommend NOT looking through the view finder, use live view with the screen. Just because a filter is blocking the visible spectrum does not mean that it isn’t letting through harmful amounts of UV, IR or other light that can permanently damage your vision.
All you need is a 5.25 floppy disk and scissors.
open up the floppy and cut a filter out of the media to fit your lens. a 5.25 inch floppy has just enough to make a filter for a 52mm lens.
I was looking for a solar filter to take photos of the eclipse today and nowhere was open or had any, so I googled around the internet for a few minutes and came across this DIY SLR solar filter that you can make with an old floppy disc. I just tried it out and it really works!
This trick works best on point and shoot cameras because the area of the floppy disc is enough to cover the entire lens.
I found if you layer a couple polarized filters on top of each other and rotate one so they cancel out almost all of the light together, then add the floppy disc on top you get a very nice solar filter!
