This wiki builds on the workflow that was followed to create proxies using this Sony F5 Production and Post-Production workflow explained here:

When you're done editing and want to Reconnect to the 4K media, uncheck the "Enable proxies" under the "Premiere Pro CC > Preferences > Media..." menu check box
 
Click OK

To check that the files are being referenced properly to the 4K media you can "right click" on the file in the Project Window and choose "Reveal in Finder"

Will now show you that the files are linked to the XDROOT folder using the 4K native data that you backed up off the Sony F5 SXS card

Now you can color correct your 4K Slog 3 footage

In order to properly "grade" or color correct the footage you must apply a special LUT .cube file to convert the color space from log to Rec.709 or Slog3 Cine.

Download the Slog LUT Here
You will need to import this into Premiere

Then after the .zip file downloads unzip it by double clicking

This folder contains the file you'll need

Select the clip you want to adjust in the timeline

Click on the color tab

Click on Lumetri Color
>Basic Correction

Click on Input LUT and then click on the drop down

Choose Browse

Navigate to the folder containing the LUT SonyLookProfiles_SLog3_SGamut3Cine

and click on Open

In that folder find the Sony SLog3 profile you'd like to apply. "LC-709" is closest comparable to Rec.709, SLog Cine is slightly different. Try both to determine which is best for the look of your project.

Once the LUT is chosen you can either adjust the footage's white balance, tint (warm/cold equivalent to Kelvin values), and various light adjustments inside the Effects panel itself

Next click "Color Wheels" section
this color workspace includes options to fix shadows, highlights, and midtones

Click on Vignette this will give you the ability to apply and customize a vignette on your footage

To explain a Vignette it's a circle that highlights a portion of the image. This is a very common and professional color correction technique. Here is an exaggerated look at a vignette.

You can place the circle in the middle or move it to highlight a portion of the image and then manipulate it.

Same image but with a customized vignette to look more subtle.

The controls are intuitive. Adjust to what you like.
Like all premire controls you can turn them off and on by clicking the checkbox in the upper right.
