Hi Guys I'm editing some headshot photos I took of a model and sometimes I check the brights and exposure of my photos with auto correct in LR/photoshop and It's totally wrecking these photos. I would say my photos are a little hot in the highlights but nothing is over exposed yet LR auto pulls the highlights way down and turns the lights up as well as the shadows. If I leave the photo the way it came out of the camera I can't see some of the skin texture clearly cause the highlights are a little bright but not overblown or peaking on the histogram. What's the rule of thumb on how bright a photo has to be in order to pop with luminosity and yet not blow out the skin tones even though the histogram says they're not blown out?

The images on the left are straight out the camera.
The ones on the right are auto corrected by LR4

Auto correct should more properly be called "auto dog's breakfast'.

It might do a tolerable job with a holiday snap or a landscape (I've not checked) but using it on most model photos is more likely to ruin them than improve them IMHO.

My personal rule of thumb for Caucasian skin tones when retouching for web viewing is not to push any channel above about 240 if I can help it as lots of cheap monitors and laptop screens start to blow out highlights to white above that.

Other than that, assuming you have a properly calibrated monitor, do what your eye tells you is most pleasing.

You shoot manual with your camera for better control (I checked the EXIF data), why would you use auto adjust in post-processing?? Follow what Stefano above said. From my experience, it is always the red channel that gets blown first.

The truth right here!

Thanks Stefano. I have a calibrated monitor but it's a cheap one so it probably blows out a little bit. I got the shot in camera with the lighting basically the way I want. It's just confusing to pull it into Lightroom and see the histogram looks good and the shot looks good but the highlights in the skin in spots are blowing out the texture.

Yeah Jeff I shoot manual with strobes and sometimes check my raw tweaks with auto correct to see what it does. Can you tell me if the skin tones on the left photo's look blown out on your monitor? Maybe it's a monitor issue I'm dealing with.

Thanks Adam. I'm going to see if I'm in that range. Do the highlights in the left pictures look blown out on your monitor?

Most of your highlights are above 240, pushing 250.

As above, most are over 240.
