A lens issue

[Mary]

Hey everyone! Within the last few days, I've noticed a little red speck of light on most...if not all of my photos. When I look at my lens I can see a little tiny white spot under the glass, and I don't know if that is what is causing the blotch. It doesn't appear to be something I could have done, as it appears to be under the glass. Do any of you have any thoughts or experience with this? I am just using editing to get rid of the mark for now. Thanks!

Do you have an example? The first thing that comes to mind is a hot or dead pixel. Is the spot in focus or out of focus?

[Mary]

It is in focus. I was wondering about the dead pixel too. Do you know what causes that? I'll have to see if I have an example.....
(Thanks by the way!)

[Mary]

You can't see it real well here, but it is on the left side of the photo. It appears very small.

[Mary]

You can't see it unless you hit the magnifier.

It might even be a hot pixel, due to shooting at a high ISO. Try a similar shot with a low ISO and see what happens.

Thank you so much for the link! I will have to try out what it suggests!
I will also check my ISO. I think I have it at 200 right now......

I think cleaning the image sensor worked! Thank you again!
