Something I'm not seeing anyone talk about much is photography during the eclipse. People are seeing a lot of photos of other eclipses, but they don't know that those photos were taken using filters for photographers' camera lens.
IF you're going to try to get photos of the eclipse, you have to have filters for your cameras, or the same thing that happens to eyes (if you look at the sun) will happen to your camera.
IF you don't have an appropriate filter for your lens, the same welding glass that works for viewing the eclipse with your eyes will work. You need #14 grade welding glass. You can get it at places like Lowes, or any hardware store.
I waited too long for a stronger filter, so I'm going to be using a combo of my 8-stop ND filter and #10 welding glass, and maybe my circular polarizer. I'll see tomorrow when I do my testing for best settings b/c these cloudy days we've had this week aren't working for me.
The ONLY time you can photograph the eclipse without a filter is when there is totality. In fact, if you have filters, then you have to take them off during the time of the total eclipse, but put them back on after totality starts ending.
