Hi Everyone, 

I am trying to recover highlight in an overexposed image:

1 - Camera Raw and Lightroom sliders values are identical. 

2 - I recover more highlight in Lightroom. (see screenshot)

am I overlooking something?

This is normal, and perfectly demonstrates the advantage of shooting raw.

 

It also perfectly demonstrates why you should do as much as possible in ACR/Lightroom before opening it into Photoshop.

 

A raw file contains all the data captured by the sensor, linearly recorded in 14 bit depth. If you could see it, it would be a very dark, monochrome image, and, notably, very tonally compressed in order to fit all the data. A good modern sensor has a dynamic range of up to 14 full stops.

 

When the file is processed and rendered into a color space, with gamma encoding, a great deal of this information is discarded. It has to be, to produce a useful recognizable image. Once gone, it can't be recovered.

Thank you for your explanation. 

That is also the reason I only shoot RAW and export the image once I processed it. 

Up until recently, I mainly used Lightroom. 

 

I supposed that when one opens a Raw image in Photoshop, it first opens Camera Raw module and was convinced it was the same as the develop module in Lightroom. 

 

Thanks again for taking the time to answer, 

Jessie
