Utilizing an ingenious spring-folded assembly design to hold them securely in place, these 90mm White-Light Universal Lens Solar Filters (2-pack) from Daystar Filters allow you to safely view or photograph the sun and solar eclipses. They are safe for solar viewing with binoculars spotting scopes, or multiple optics and lenses without having to move the filter. Made from 12312-2 ISO-certified SOLARITE film, each filter blocks more than 99.999% of intense light, plus 100% of harmful IR and UV radiation to reveal sunspots and super granules on the solar surface. Made to fit on the front of camera lenses, telescopes, spotting scopes, binoculars, or other optics and imaging devices, they accommodate housings, sunshades, and dew shields with an outside diameter from 85-99mm (3.34-3.89"). The filter has a clear aperture of 90mm, so vignetting may occur when used on lenses and optics that approach the maximum recommended diameter in the size range.

question
I used these filters for the solar eclipse's partial phases and now am in edit mode. Can anyone advise if there is a digital filter setting in Photoshop or Lightroom for making the color look more natural? Primarily for images shot in RAW but also JPG. Thanks!
My filters worked well on my 11x80 Celestron Comet Catcher binoculars, but I sure can't help with photoshop. Weather in Murphy, North Carolina was perfect!

question
Does anybody know how quality and results will differ when using this versus more expensive ND glass solar filters (i.e., the Format Hitech ND 5.4 and the Marumi ND 5.0)?
Finally tried it this afternoon, using a 150-500 Sigma on a Tamaron 1.4x teleconverter on a Nikon D810, f/11 at 1/100 sec at ISO 500. Did not see any noticeable distortion when magnified approx. 50x. I can't compare it to the glass solar filters, but I suspect the more expensive ones use the same mylar sandwiched between two optical glass panes, same as polarizers. Folding it to fit the lens had to be done with care to avoid creasing or scratching the film, but it can be done if you take your time. For now, I'm keeping it protected until a certain astronomical event in August. It probably won't survive a lot of use without getting scratched. I would go with the expensive glass filters if doing much solar photography.

question
Does this filter have an equivalent ND filter level?
From my reading, solar filters cut down the light by 1/100,000, so 100,000, 50,000, 25,000, etc comes out to ND 4-6. But, also from my reading, solar filters also block UV about 100%. PLEASE BE SURE your solution blocks UV too. I don't trust anything but proper solar filters.
