After the solar eclipse, we'll have a bunch of cheap (or expensive) filters lying around. Aside from pictures of sun spots, what can we do with them?

They may useful for taking pictures of other things with long exposures, such as landscapes with many people. If the exposure is long enough, and the people move around, they may "disappear".

This was ISO 1000, 30 second exposure so it may be possible to get a minute or 2 exposure in bright sun at ISO 100

The down sides:

  • The white balance is off, but might be correctable in post
  • Mine needs a bit of taping to eliminate a light leak
  • Need to work completely in manual mode to set exposure and may need several shots to get a decent exposure
  • Any leaves and branches in a wind are blurred
  • It's a bit grainy to my eyes, but maybe some smoothing could be applied


Posted in this sub-forum as the discussions about solar filters are here.

I have some of those cheap solar glasses that have the ISO CERTIFIED ratings but as I mentioned cheap . Mine will go in the trash when it's over . Even tho they are CERTIFIED they are not the very same as true Solar filter such as the Baadar Solar white light filter or the ones sold at Thousands Oak . For a good white light image Baadar can't be beat but they cannot be used for landscaping . The only thing better are Solar scopes built. specifically for solar viewing and imaging and they are very expensive !

It looks like a Kodak Instamatic picture. :)


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

It does have that appearance. Fun to play with though.

Mine was bought for the Mercury transit last year. I'll (hopefully) use it tomorrow and then it will go into storage until the next eclipse in 2024, which will also cover my local area.

Astronomers Without Borders would like the eclipse glasses, so don't throw yours out.
