Username is crabbi cuz i have a crab tattoo on the back of my neck (long, complicated story) and my name is Cathy...crabbicat. Wasn't offended, just clarifying. :-) And just so everyone is clear (not wanting to hurt feelings here) the hair was stuck to the side and not lying on the sensor.

Hey, Cathy, thanks for those clarifications.
And a special thanks for exonerating me and my assertion that the hair was NOT ON THE SENSOR, despite all the mildly insulting criticism I received for not understanding math, optics and diffraction.
I would still like to see the full second image for comparison of what happens to a photo when the hair IS closer to the sensor (I assume your second post was a crop of an image taken after you tried to dislodge the offending hair). I think it would be instructive to readers.

No, it wasn't a crop at all. Just sooc.
OK. The second image is quite a bit smaller than the first one, but that could simply be a result of how they got uploaded.
Do you think the hair moved physically between the two images, or is the extra definition simply the effect of the f-stop change? I tried comparing the two images and it is possible that the hair was in the same location in both images.
Maybe giving us the relevant EXIF data (ISO, shutter speed, f-stop, focal length) for each image would be helpful.

I don't think it had moved. I think that one was landscape and the other was portrait. The hair was stuck on something in there so I'm fairly sure it didn't move. I think that closing down the aperture made the difference in appearance.
