Sony 'striping' Issue with Backlight: Step by Step to Fix This Issue

Hi all, in this blog post, I want to document the step by step process to fix the Sony 'Striping" issue. DPReview reported this issue in 2018 with this article Sony "Striping": Here's the Fix. Below are some of my detailed steps that I followed to fix the issue.


The problem


When I shoot backlight using the Sony A7iii, sometimes I will see the strips like the screenshot below. This happens to me on multiple lenses: FE85mm F1.8, Zeiss 40mm F2, Zeiss 55mm F1.8 and Zeiss 35mm F1.4. Based on DPReview's article, it's because of the sensor design with Phase Detection auto-focus.

Step 1 - Open the actual raw file location and copy to a separate folder. In this way, it will be easier to upload to the browser. (Right click on the photo and select "Show in Finder".


Step 2 - Open this link: http://aggregate.org/DIT/KARWY-SR/karwy/test/karwy.html and Upload the Sony Raw file to that website.

Drag and drop the file to this webpage.


Step 3 - Once the website finishes the fix, click on "Link to Processed File" link in the bottom of the fixed image.


Step 4 - Download the file and rename with the extension of .ARW for Sony format.


Step 5 - Re-import this updated file into Lightroom.

Summary


I want to document these steps in case others have similar situation like mine. Hope these are helpful. If you don't shoot a lot of backlight shots, you won't notice this issue. And this issue came across with multiple Sony and Zeiss lenses in my experience. I hope Sony make a firmware update to fix we don't have to go through these steps for each image. Let me know in the comments below if you have encountered the similar issue.
