Over exposed

Is there a way to fix over exposed shots ?
I was at a party / family reunion , set up camera for in house and under canopies - running ISO 800 - 7D / 17-55 . Anyway the under exposed I can fix in P S .
The over exposed were of the group , neighbor took them, but he switched from program the either AV or TV . [I shot a few test shots in program and they were usable] Both were set at 800 ISO - babies and kids - did not want the flash , so maybe 15 shots of family over exposed .
The guy was nice and I should have just said no and P S-ed myself in .
I did a search , no mention of how or if possible to fix .
1st 2 I can fix .
Next post I can't figure out how to .

The one of the left is underexposed. The one on the right is ok by my eyes.

I have been in a similar situation where I was shooting indoors with flash and high ISO. I thought I was finished shooting, but then fired off a quick shot when I went outside without changing the camera settings.

I converted to black and white because I couldn't get any decent results in color. This edit was done in Lightroom, so it should be the same in Photoshop.

- Reduce exposure by 2.25 stops
- Increase recovery to 90
- Increase blacks to 23
- Adjust tone curve, highlights -14, lights -16, darks -49, shadows -46
- Convert to black & white. Reds, yellows, greens are around -20. Blues and purples are around +15. Adjust to taste.

The end result is far from perfect, but it preserves the memory pretty well.

Mark-B that's pretty impressive! Was that a jpeg or Raw?

To the OP, well, you see what Mark did.

My only suggestion is a "starting point".

In your software try first just pulling your Exposure all the way back to see what is actually possible. This will show you what highlights are totally blown and which have some bit of data that you can recover. From there, of course will be a labor of love to apply various approaches to getting things right.

Always in raw

Just FYI, switching from P to Av or Tv would not change the exposure. Either he put it in M with an incorrect setting or he added a lot of EC.

It's in manual, ISO 800, f/4.5, 1/125.

Thanks -
I am not sure what he did . I may have been in full auto . After I reviewed the shots , I dropped the ISO to 200 .
I had a couple of shots last year where the bride and groom where coming in thru a door and almost everything was blown out / over exposed .
I think I just masked out the bright stuff , opening in PS shows 3 layers . I just don't remember how I did it .

There is definitely a limit to what can be done even with exposure corrections done in RAW conversion!

First, a series of shots, shot as metered with incident light meter and others overexposed up to +3EV...
0EV

Now, above four shots, as corrected during RAW conversion...

0EV

Sure it could, in AV if the aperture was set wide and the camera did not have enough shutter speed available to make a correct exposure, it would overexpose.

That would depend on whether or not "safety shift" was enabled...
