Postprocessing Photos shot using the RAW file output format

This sequence of three photos shows the initial file and the final product.
Photo taken with a Canon 6D full frame body using a Canon 135mm F2.0 prime lens.
I tend to try and not use iso settings higher than 5000 to avoid excessive noise but fortunately the Canon 6D has excellent high iso performance and is about as good as you can get for the dollars spent.

Using this photo shot of Darelle Holden, Michael David Marcus and Matt Jorgenson
with the goal of isolating Darelle for a pseudo portrait treatment.
Sorry guys!

The first file shows what a RAW image looks like straight out of the camera sensor and with no processing applied from within the camera.
There is plenty of overblown red/magenta tonality thanks to the stage lights being set to magenta color tone and the glossy red walls also  reflecting a lot of it.
Exposure on this shot was just about as far as one could go without blowing out the exposure of Darelle's face.

This next photo shows the first step of correcting a lot of exposure, white balance and color details,over 50 parameters of adjustments.
Performed using Adobe Lightroom.
The third file shows the 2nd file after some creative editing and cropping of the image components using Adobe Photoshop.
Some parts of the image are removed to make the composition less cluttered like the yellow sconce light and the wall edge on the left.

Noise reduction is applied and after that some creative sharpening is also applied.
And finally some amount of skin tone correction is performed.

It takes a lot of creative digital filtering to get the skin tone closer to a natural tone but given the huge amount of illumination by the magenta toned stage lights, it really is close to impossible to achieve an authentically natural skin tone.

Some amount of detail is lost after the cropping of the photos but for this portrait style shot it works fine. Darelle's earrings and her blouse's shiny details are crisp enough even after the image cropping.
