Pink line on all R6 images

deedeeo — Sun, 08 Jan 2023 22:34:43 GMT

A pink line appeared on my screen while shooting on my R6 (less than a year old). unfortunately the line is on the images. Same issue with different cards and it's consistently there.

I haven't brought it back yet, but my biggest issue is how to fix the images?

Hard to tell without a raw file.

Here is the raw file

Affecting two columns beside each other and gets stronger a bit down. No idea how to fix that. Perhaps a bad pixel filter https://rawpedia.rawtherapee.com/Dark_Frame#Bad_Pixels

or Pixel fixer if you convert to DNG http://www.pixelfixer.org/

Pixel fixer didn't support your raw file.

RawTherapee worked but doesn't read Exif from CR3. I converted first to DNG.

To me it seems like your sensor has been exposed to a laser. The purple dot/dots.

Anyway, I created a badpixel file and named it Canon EOS R6.badpixels

I used LibreOffice Calc to generate the numbers.
x1466,y0
x1466,y2
x1466,y4
etc...

I noticed the columns and every second pixel in each.

Badpixel file to put in your dark-frames directory https://drive.google.com/file/d/1pSkGYZ-8N1bdegbKmjbDn6iXCxDUQ0nd/view?usp=share_link

Still a visible line at the bottom.

There are some more purple dots to be marked as bad pixels and at the bottom a line is still visible.

Probably not the solution you are looking for, but I was curious to see if I could fix it quickly in one of the programs I have. I dropped it into PaintShop Pro 2023, which opens Canon Raw files, and used its "Scratch remover" tool. It only took about 5 minutes, if that long, to manually remove the line. I'd guess most editors will do this, but I really like the way PSP has the tool set up and it blends quite nicely.

When I saved the Raw from PSP to JPeG, I did add a touch of sharpening. Other than removing the pixels, cropping (to show the removal), and resizing, that was all I did to your file.

Nice shot, and sorry you are having this issue 😞

Thank you so much for your help. so I'm trying to export them as DNG's to begin with and lightroom doesn't seem to be exporting them. did you use lightroom to export it?

I used Adobe DNG Converter to convert, but you may try to load the original CR3 files also in RawTherapee 5.9.

New updated badpixel file https://drive.google.com/file/d/1bgL75LLHZI6sIOrgm9Ov7NnxKIg-QpeN/view?usp=share_link

Removed the line and removed more purple dots.

Thanks for your help Peter, I'm struggling to load the files into RawThereapee. Not sure what I'm doing wrong. I haven't used the software before.

Also I'm not sure what you meant by the following

What do you mean by badpixel file? Is this needed to use Rawtherapee?

Sorry for my ignorance.

I managed to open the folder in rawTherapee now. What do I do from here? Did you do some command to the image or edit it somehow to remove the bad pixels?

TIA

As written at RawPedia:

So you need to put the badpixel file in the same folder as you dark-frame folder.

So Preferences, Image Processing. Choose a folder for dark-frames. After that you put the badpixel file in that folder and restart RawTherapee.

When you have it up running you can just export to 16 bit Tiff and edit in Lightroom if you prefer that.

Hi Peter! I also have the same problem on my photos taken by 60D. would you please make a tutorial on how to use raw therapee? thank you so much!

Re: Pink line on all R6 images

Peter — Thu, 02 May 2024 13:25:55 GMT

Sure, but it also depends on how serve the damage is https://kameratrollet.se/use-rawtherapee-to-deal-with-laser-damaged-camera-sensors/

how did you generate the .badpixels extension file?

Re: Pink line on all R6 images

Peter — Thu, 02 May 2024 14:46:22 GMT

I just right clicked and created a new text file. I also changed the extension from .txt to .badpixels

You can reuse the one from 5DIV and just change the name.

This is my raw photo. https://drive.google.com/file/d/1awBb_02EjU0r2NRywir5eKStSJzjpQsN/view?usp=sharing https://drive.google.com/file/d/1awBb_02EjU0r2NRywir5eKStSJzjpQsN/view?usp=sharing . I tried using the 5DMIV but it made the photo look pinkish. My apologies for bothering

I will take a look when I get home.

Re: Pink line on all R6 images

Peter — Thu, 02 May 2024 16:10:00 GMT

I downloaded your file. Are you sure the sensor has been hit by laser? It seems like something else. The badpixel list will not work for this. Are the lines moving around or they are always at the same place?

Perhaps a dark frame will work better. Could you take a raw file with lens cap on? ISO 6400, f/5.6 and 1/100 sec.

I do not know much of the history, or the owner. But he gave me 2 batteries, an original and a third-party one. I noticed that those lines appear on the third-party batt.
