Fuji please give us pixel re-mapping

[adventure_photo]

I currently own the Fuji X-T1 and X-E2 and both continue to have issues with hot pixels showing up in every single frame in the exact same spot. I also used to own an X-E1 and I had hot pixel issues with it as well. The X-E2 went to Fuji repair in New Jersey a total of 3 times so far for pixel re-mapping. They covered it under warranty, but on each occasion I was without my camera for about two weeks each - so a total of six weeks without camera. After each pixel re-mapping things were fine for a while but eventually hot pixels started showing up again. At this point I've decided it's just not worth it to send the camera in as it never seems to really work and it's easy to clone out the hot pixels. Some are white, some are red, and some are blue. They show up in the exact same spot on every image. I also use Nikon cameras and have for years and have never had a hot pixel issue with any Nikon ever.

Fuji, could you please give us pixel re-mapping in camera through a menu item? Canon and other manufacturers offer this and it seems so simple. I'm sure it bogs down your system and repair facilities having people send their cameras in for a simple fix like remapping. At the very least, a user-downloadable utility that could be run to do the remapping ourselves.

Do others agree that this would be a nice feature and have others too had issues with hot pixels?

I totally agree.
Though there is something unclear for me. LR removes automatically dead pixels, does it mean that it could be simply done in the Jpeg engine without the need to remap? I doubt I guess nothing replaces pixel remapping.

One of those things I miss from drifting away from Pentax. The very first thing I would do with a new Pentax was run a pixel map.

Adobe raw converters automatically take out hot pixels, and one can set up an action in Photoshop to take them out as well.

 

[adventure_photo]

For some reason I noticed that LR doesn't seem to automatically remove them from my Fuji cameras. The hot pixels are visible at 100% in every image viewed in LR. Maybe that's why I've never seen them with my Nikon cameras because LR is automatically re-mapping. My X-T1 is the worst right now with about 5 active annoying pixels that I have to clone out in every image. Sometimes they are easy fixes, others require a bit more time or opening in Photoshop for more detailed cloning work. Added firmware upgrade, problem fixed.

 

[adventure_photo]

Can you please tell me how do you create an action in Photoshop to remove them? Can you briefly explain? I know how to use and create actions, just wondering what specifically are the steps/filters/etc in the action? That would be great to be able to do that. Thanks for the reply

Otherwise, a "simple" script or program could fix your jpeg pictures instead of doing it manually.
I wonder also of mirrorless have more dead pixels than DLSR, it would be logic because the sensor is more exposed.

then switch to Olympus: it takes me 30 seconds to perform dead pixel mapping. It's in the menu.

Good luck.

Gaaa. It's supposed to be available in CS6, but it appears broken unless you are using the pay per view version.

I'll research this a bit more for you and get back to you in a day or so.

That would mean tolerating Olympus ergonomics, which are just like all the mainstream DSLRs on the market downsized. I went to Fuji because for me their cameras have superior ergonomics for the way I shoot.

Had I wanted DSLR ergonomics I could have bought another DSLR.

OK, I managed to remember how to do this. I'm not sure if this works in versions of Photoshop prior to CS6, but anyway...

In the actions menu, turn on Allow Tool Recording.

I would take a picture of a plain surface to make seeing hot pixels easier, and open it in Photoshop.

Make an action of cloning the hot pixels from pixels adjacent to it.

Now, you can run it on individual images or you can run it as part of a script and do an entire directory.

Does anybody know how pixel remapping works in LR ?

I mean how to make sure a pixel is really dead ? The value read may be the correct value.

I guess pixel remapping is still neeeded and that it can not be replaced with LR, I would be curious to know how LR works...

A hot pixel always reads 255 in whatever color it is how in, a dead pixel always reads 0. A pixel reading either 255 or 0 is more than likely going to be either stuck or dead, especially when the surrounding pixels read more normal values (which will be virtually always). The converter is just looking for pixels that are fully saturated or desaturated and makes them the same as the pixel beside.

Thanks for the information !

I was wondering whether it was working on several pictures to confirm the hot/dead pixels.

This algorithm is not perfect, because it can consider normal pixels as dead/hot, and the opposite can also be true also !

I understand that it works in most cases and that the mistakes won't be very visible, though I would prefer having a feature for remapping with the camera or have it implemented in LR in a most rigourous way.

In the internet forum universe where even the absolutely remotest, probably wouldn't happen more than once in an infinite number of times possibility gets inflated to an everyday occurrence, I'm sure it isn't perfect.

For the rest of us, having a hot pixel given the same value as the normal one beside it works perfectly in practice.

Of course, it is an imperfect world

I understand that it works in most cases and that the mistakes won't be very visible, though I would prefer having a feature for remapping with the camera or have it implemented in LR in a most rigourous way.

I'm not sure what can be more rigorous than the way they do it.

The possibility of error is virtually non existent. What is the likelihood of having a sector of pixels all reading close to the same value and one individual pixel in the middle reading either 0 or 255 in any image? The odds, I would think, are so close to zero as to be zero.

Let's take an exemple:

A potentially hot red pixel surrounded by red pixels with values around 250. If you consider it is a hot pixel even if it is not the case, I agree that this will not be dramatic.

If you consider in the opposite it is not a hot pixel whereas it is, it won't be corrected.

I think it happens but that the consequences are minor.

Being more rigourous would be telling explicitely to LR which pixels should be corrected. LR could also detect them by analyzing several pictures which would confirm or not that the pixels are really dead/hot.

Do not hesitate to confirm or not what I say.

The point is, it will be virtually impossible to get one pixel in a cluster maxed out unless all the pixels around it are also maxed out. That is why raw converters are able to accurately remove hot pixels.

If one pixel is maxed out, and the clusters around it are also maxed out, it's not a hot pixel, and won't be mapped by the converter.

Same with dead pixels.

If you consider in the opposite it is not a hot pixel whereas it is, it won't be corrected.

I think it happens but that the consequences are minor.

It might have happened once in all the billions of digital images shot to date. That is how unlikely your scenario is.

All you need to do is take a color picker to a few images and see exactly how many areas actually max out the DR.

Being more rigourous would be telling explicitely to LR which pixels should be corrected. LR could also detect them by analyzing several pictures which would confirm or not that the pixels are really dead/hot.

I won't confirm or deny. I do have a certain amount of blind faith in Adobe. They've been toing this digital imaging thing for nearly two decades. I suspect they have a pretty good handle on it by now.

OK but this was not my example.

and won't be mapped by the converter.

Same with dead pixels.

This is a concrete example and your response is not clear.

I have a red pixel (value 255). I shoot a red flower, surrounding pixels have values around 250 (close to saturation and some saturated). This is not an unlikely scenario.

How can you say if this pixel is hot or if this is a normal pixel ???

At most, the error will be 5, not really important but it still exists and I think it can happen more often than you say. And the error in the opposite way can happen also.

Unless I am missing something but I am not convinced.

If you consider in the opposite it is not a hot pixel whereas it is, it won't be corrected.
