I am not in the direct path but should get a nice view if it's not cloudy out. Can I hold a piece of welding glass over my lens to help keep my gear safe? I see solar filter talked about but when I click on the links for more info they just go to the glasses.
 
What about a circular polarizer? Would that be better? 
 
Here in Florida my chances aren't that good as we are in the summer afternoon thunderstorm season but if there is a little hole in the clouds it would be nice.
 
Thanks for any info.

A circular polarizer won't do it, you need a solar filter or a film sheet.  Tony has a good video for photographing the eclipse. Good luck!

Thanks. I found that vid after I posted here.

 

I am too late to get anything here in time as well. Of coarse the film is all out of stock in any size that will work for me and back in stock on Tues. 

 

I have welding glass here. Will that work or will my camera still take a beating?

From the NASA website:

 

"Viewing with Protection -- Experts suggests that one widely available filter for safe solar viewing is welders glass of sufficiently high number. The only ones that are safe for direct viewing of the Sun with your eyes are those of Shade 12 or higher. These are much darker than the filters used for most kinds of welding. If you have an old welder's helmet around the house and are thinking of using it to view the Sun, make sure you know the filter's shade number. If it's less than 12 (and it probably is), don't even think about using it to look at the Sun. Many people find the Sun too bright even in a Shade 12 filter, and some find the Sun too dim in a Shade 14 filter — but Shade 13 filters are uncommon and can be hard to find."

Of course, this is for your eyes, not sure if it relates to a camera lens.

Thanks Bob for the link and info.

 

I am not planning on looking into the sun just using live view or even tethered to my tablet would be best. I just wasn't sure if my camera sensor would be damaged using just the welding glass. It is shade 10. I am in the 85% eclipse area so there will be lots of sun still.

 

Thanks for the help folks

The primary danger of direct sunlight to the eye is photo-activation of chemicals that produce free-radicals in the eye, whereas cameras and lenses only have to worry about thermal heating which requires a lot more energy. So even if shade 10 welder's glass is unsafe for the eye, it should be perfectly fine for your lens.

60% chance of rain here.  I'll watch it on the computer.

My wife asked if I was going to take photos of it. In NJ, we are getting a partial and I figured a while ago to let others with much better equipment than I have take the photos and I can view them. I expect NASA to have some spectacular photos.

I totally understand letting someone else take the photos but to me that's like letting someone else take moon pics, or bird pics because they have better gear or more experience. Just something about doing it yourself. When I show someone a pic I can say yes, I took that.

 

I may not get anything to show but for the little time involved I am going to try.

 

Thanks for all the tips and info everyone.


Terry
