Preview loosing colour in develop persona

[adrian6t8]

All of a sudden whenever I click on develop the image show in the main window looses all colour output, this is with previously saved images that were fine before.

I'm not sure if I've accidentally switched a setting.

If I cancel the image returns to being colour, does anyone have any ideas what I might have done, it's now stepping me from editing any images as it loses the colour info in develop

@adrian6t8, welcome to the forums

We're going to need more information to begin to guess at what's happening. Please provide a screen recording showing the entire application in the Develop Persona. We need to see what settings you applied.

Thanks, here's a video, as you can see when I flick through the settings in develop there's nothing that should be making in monochrome, and if I cancel it returns to colour

A bit of further information, once what ever it is is saved in the file it doesn't matter if it's on windows or mac I have the same issue.

I've not knowing switched anything on in develop that could make it monochrome, e.g. desaturation or the black and white filter.

You'll see as soon as I go in to develop the histogram channels all become the same.

Thanks for providing the video. Sadly I can not see anything that would be causing the monochrome. Could you attach your afphoto file so it can be checked? I may be missing something, or what's causing it is not shown in the video. I even tried replicating it using the same adjustment and filter layers, applying the two gradient overlays in the develop persona. The only way the image looses it's saturation is to manually remove it. IF the gradient overlays were responsible, it would remain monochrome once developed. If it's one of the adjustment layers, HSL, Curves, it would be monochrome in the Photo Persona.

Have you tried removing the overlays in the Develop Persona? Also try moving the sliders in the Basic Panel of the Develop Persona to see if you get a major, sudden change. They shouldn't be, changes should be gradual while moving them.

You could also try, in the Photo Persona, to Hide the Adjustment Layers, one at time to see what, if anything, changes.

Hopefully someone else will jump in here, and see what I may be missing.

Thanks for looking Ron, it is a strange one, removing the gradients makes no difference, I'll attach the afphoto so you can look and see if it's doing it for you.
The same file for me has the same issue if loaded into mac or pc version.

I also have other files that its started happening on so it would be great to find a solution because at the moment I can't go back and tweak the raw.

I'm not Ron but it is doing the same for me. I have no idea why. Maybe a mod like @MEB or one of the others can take a look at it & see if there is something that explains it....

I am way way out in the weeds grasping at straws mixing my metaphors with this....

Perhaps the software is confusing the file as a monochrome raw file from the supported cameras list

Ricoh Pentax K-3 Mark III
Ricoh Pentax K-3 Mark III Monochrome

I see that this is from a Ricoh GR Mark III, not a K-3.

Thanks, I've been wondering if it's something in recent update, as this used to work fine,

If it was always monochrome I would have never been able to develop the colour image, it's just something that has started recently.

Old Bruce that's an interesting idea, as I noticed that I've got a ! next to the lens in the raw persona which I didn't have before.

The other thing to note is if I go back and load the raw file again in a new instance, it's fine the colour is back

Also  I just discovered I can fix it  by using the resource manager to reload the raw, everything is then back to normal, so I think it's somekind of weird glitch with the afphoto file, somehow getting corrupted, I guess only the developers might know

[carl123]

I don't know how it got to this stage but I know how to "fix" it

In the Photo persona select the RAW layer then with the Move tool selected you will see an option in the context toolbar to Replace Image click that and select the same original RAW file, (the screen may go black for a few seconds as it loads) Now when you go into the Develop persona it will be in colour

If you don't have the original Raw file, just use the Resource Manager to change the file from Embedded to Linked and you can effectively export the original RAW file to any folder.

That's it. But there's something I don't understand. In the history panel if you cycle to just before the Raw file is replaced and forward again, the replaced Raw looks slightly darker than the original, which suggest something else was done to the original RAW file (in APhoto) but I can't figure that out at the moment.

 

[adrian6t8]

@carl123 you must have been posting that just as I'd discovered it also, but yes I also noticed that the replaced version is darker too, by quite a bit possibly a couple of stops when I did it.

I would suggest switching on File > Save History with Document immediately you notice it happen again on a new file, then save the file

That may help us find out what triggers it in your workflow

Also visit the Develop persona a few times during your editing and at the end to see if it has occurred (just cancel out and carry on working, if OK)

[Ron P.]

I don't know what it is about the image causing it to be monotone/monochrome. I downloaded a couple of sample RAW files for the Ricoh GR III. They do not have the monochrome problem in the Develop Persona.

[adrian6t8]

Thanks to everyone who's looked at this, I wish I could get to the bottom of this as it seems like a plague with more and more of my files affected when I go back and want to tweak the raw. I'm still wondering if I should report this as an issue, or is it just me...
