I have a hot pixel that's been on my 6D since pretty much the beginning. It shows up as red and is in the same spot in every photo. I can spot brush it out, of course, but it's annoying. It happens at all ISOs, not just higher. Even at 100. I've gone through the sensor cleaning a couple times (the one in the menu system...I have no intention of touching my sensor; plus that probably won't make a difference anyway). Sensor shake doesn't help.

I've heard that Lightroom will automatically fix them as I import raw files. Is that true? If so I'll buy it. I like DPP, but Lightroom is good software (better really).

And is there a setting on DPP that will automatically delete this spot?

Finally, since this appears to be a permanent thing, is there anything I should do, such as send it in, or should I just ignore it?

Thanks

In the first pic, follow my chin down about four inches to see the small, red dot.

The second pic is cropped at 200%.

Like I said, it's a very easy fix when processing, but that requires me to always open a file in photoshop after running it through DPP (unless DPP has a cure).

I'd rather not have to spot touch every single photo I take.

NOTE: Don't worry about all the white spots. That's my darn t-shirt. These were just test shots using a strobe.

Update. Okay, I learned there is a fix in DPP, but I'm hoping I can automate the process since it's going to be in the same spot everytime.

From what I've read here and there, hot spots are normal and not cause for concern (provided the software can easily spot and nix them.

The question for me now is: How to I make this automated so I don't have to think about it?

I use Lightroom and have a default preset setting that I made, I use it on ALL my images, just has mild base adjustments and the noise reduction and profile settings get rid of the hot pixels.

You are getting rid of real photo information unnecessarily. Let the camera map out stuck/hot pixels. No sense degrading your images for something that can be done BEFORE they get to your computer.

HEY, it worked! Wow!

Thank you so much. That bright red dot was really bothering me. Not anymore.

Basically it was this easy:

1. Go through the menu to manual sensor cleaning.

2. Click start manual sensor cleaning.

3. The mirror lifts up (I kept the lens and lens cap on the whole time).

4. After thirty seconds turn the camera's power off. The mirror flips back down.

Done. Hot pixel gone.

As someone else mentioned, the camera must remap itself or something, eliminating the hot spots.

:)


Thanks again. I wouldn't have known that trick without your link.

Thanks for that. Sounds like a good thing to do now and then - just in case.


Life is for living, cameras are to capture it (one day I will learn how!).

Good to get confirmation that it works on the 6D. :-)
