Highlights & Shadows in Photoshop

Recommended Posts

There has been a lot of talk regarding highlight and shadows lately.

Is there anybody here  using that function in PS? Go to Image>Adjustments>Shadows & Highlights>Advanced.

I find it a lot more useful than LR or curves/levels.

Of course there is a YouTube tutorial from my fast talking teacherūüėČ

I much prefer controlling the highlights and shadows in the Adobe RAW converter.

Absolutely agree. And I don't go willy-nilly opening up every shadow I can see either . . . not all shadows need "opening" up, something "auto" simply cannot address.

I'll third that. It is far better to work on the raw file. You can only recover what you have got in the first place so if your raw conversion is losing detail in the shadows and highlights then they won't be there to recover on the converted image. Also for dealing with noise, which can be particularly bad in shadow areas, working on the raw image is far superior. 

 

Even if you only have a jpeg or tiff to work on, I would think it far better to use the ACR filter in Photoshop nowadays than messing about with that shadows/highlights adjustment.

Thanks everyone for the feedback. I didn't realize that he was using a jpeg for an example.

One way around that is to use PS as an external editor in LR. Right click on the thumbnail (edit in) and chose PS. If you haven't got an external editor set up, go to Choose Lightroom > Preferences (Mac) or Edit > Preferences (Windows) and then click on the External Editing tab.

You can then do all your edits in PS, including Nik in the 16 bit tiff  file. When finished, click save (not save as). That will take you back to LR with 2 files, original and edited.

Not all shadows need "opening up" but some do.

Anyway, I like itūüėź

I think the point is being missed here, the point being that you can't edit a raw file in Photoshop. The raw editing has to be done in Lightroom or Adobe Camera Raw before opening it into Photoshop. And the point of editing the raw file in LR/ACR rather than a converted version (PSD, TIFF, JPEG or whatever) is that the ability to recover shadow and highlight detail is far greater working on the raw file than working on a PSD, TIFF, JPEG or whatever. 

 

If you only have a PSD, TIFF, JPEG or whatever to begin with (perhaps you shoot JPEGs only or you are scanning or copying film)  then sure go ahead and edit the shadows and highlights in Photoshop. But in that case it is probably better to use the ACR filter within Photoshop than the Shadows/Highlights adjustment as it has all the familiar controls for anyone who uses LR or ACR and is extremely powerful in comparison to the Shadows/Highlights adjustment. To get the ACR filter, hit Filter-Camera Raw Filter...

 

But each to his own.

No points were missed. 

The RAW files may very well contain more information than a 16 bit ProPhoto TIFF file, however the difference may not be significant.

I put this info out for anyone having issues with shadows and highlights. For me LR and ACR (same thing almost) weren't as good as this method.

Just my opinion

Thanks - I didn't fully appreciated the benefit until I experimented with an image with an overexposed sky. Reducing the exposure by 2 stops on the RAW file using ACR RAW creates a much better result than converting the uncorrected RAW to a 16 bit PS file and then making the exposure adjustment using the Filter>Camera Raw Filter.. in PS.

 

The following shows the difference. Top slice is original image, unadjusted with over exposed sky. Middle slice is after applying -2 stop exposure correction using ACR on the RAW file before RAW conversion and exporting to PS. Bottom slice applies the -2 stop correction using Filter>Camera Raw Filter.. in PS after RAW conversion. Interestingly applying a -2 stop adjustment using the Image>Adjust>Exposure in PS produces a rubbish result which is even worse than using Filter>Camera Raw Filter...  No idea why that should be.

NB. I also tried the above test in 16 bit ProPhotoRGB space and the results are still broadly the same. Making the exposure adjustment before RAW conversion does a significantly better job than doing it afterwards. It's easy enough to try for yourself.
