What was the brightness result/value within the calibration software when it finished? Most people have this value between 85-110 cd/m² usually depending on room lighting.
It is very possible your monitor is set too dark so that when things look good to you they look too bright to anyone else using a calibrated monitor. This is kind of backwards though, most people with problems have their monitor set too bright which would their images look dark to most everyone else.
Sorry this reply took so long, I have been out of town. 80 is pretty dark for me on this end. I would try starting at 95 within the software, that is kind of average from the different settings I read about.
I recalibrated my monitor at 100. There was no 95 setting. It is definitely brighter than before.
The interesting thing is when I optimized my image. I applied sharpening and an s curve to increase contrast. I did not adjust brightness or color. It seems surprising to me that the image would appear over exposed to somebody else.
At the new settings the image still looks good to me.
Think about setting up a print viewing station where you can control/standardize the light in which your prints are viewed. I just set one up as I got very credible feedback that my prints, all B&W, we're uniformly too dark.
There seems to be something missing here. You re-calibrated your monitor and state it was "definitely brighter then before,"
That should mean the image is also now definitely brighter then before yet you say it still looks good to you. If it looked good to you to start with, before re-calibration, how can it now also look good "definitely brighter" ?
"It seems surprising to me that the image would appear over exposed to somebody else."
Lets assume that the image was over exposed to start with. If you monitor is not calibrated properly and is displaying images darker then they really are then it should not be surprising that people with a properly calibrated monitor (the correct brightness) are seeing it over exposed. Your not seeing your image as over exposed because your monitor is set too dark. I hope this helps.
