Is a .on1 file really a JSON file?
I recently noticed when a particular adjustment layer is turned on that I see weird artifacts in the image. Not sure how to fix it I decided to take a quick peek at the .on1 file. It seems like it's just a JSON file. Does anyone know if this is true?
I'm hoping someone from engineering, who may be lurking in the forum may give me a quick yes/no answer.
Thanks,
Dave

Hi David, while the company does monitor these forums they do not participate here. The people you talk to here are just other users like yourself.
Having said that, I've taken a look at the .on1 files too and yes, they are JSON files. All of the editing data however is binary so there isn't any way edit it. The only text is the metadata for the image.
What kind of artifacts are you seeing? What kind of adjustment layer is it? Is there any masking that may need to be cleaned up along the edges? A couple of screen shots showing that adjustment's settings with it turned on and off so we can see the artifacts you are seeing might be helpful.

Hey Brian,
Thanks for confirming that. I noticed the editing was in binary format. I basically have a single mask in play. I simply have it inverted for different uses. I have narrowed down the issue to a local adjustment mask. When I remove the midtone adjustment for the mask the artifacts seem to go away. I have put all of the screenshots up here because the platform won't let me add png or jpg files to this post. artifacts post screenshots
You will see 4 pictures. Two of the adjustment panels, one with the midtone set to 20 and one with it set to 0.
When midtones are set to 0 the artifacts don't appear. However, as soon as the midtone is set to 20 they show up.
Thanks for the help.
Dave

I'm not sure if this helps, but the RAW file was taken with a Nikon D500.

I just exported the file with the adjustment layer turned off and the file does not exhibit the artifacts.
One more thing...I used the Super Select AI mask tool to create the mask and then used the regular mask tools to refine the mask.

Can I see your file? Zip together the NEF with its .on1 sidecar and upload that to your sharing site then post the download link here for me. I can see the artifacts but I'm not sure what their cause is although I have a couple of ideas. Possibly masking but I need to take a look through it to be sure.

I just uploaded the zipped NEF and .on1 sidecar and put it in the same folder.
Thanks.

I am not seeing those artifacts on my system.
This suggests it might be a video card driver issue.
I do have a couple of suggestions though. First, you said you used the AI masking tool then cleaned it up. That's OK, I do the same thing. My suggestion here is to go ahead and retouch that area in the masks. Paint it in or out as needed for bird and background. Be sure to get those in the Effects stack too. It may not fix it but it doesn't hurt to try. There could be something funky with the mask in that area that manually painting it in/out could fix.
Another thing I noticed and it could be related too, is that it is way over sharpened. The default settings for both NoNoise AI and Tack Sharp AI are seriously too aggressive IMO. I always use the Both tab because I may want to use both. If I don't need one I don't have to apply it and it is no different than using the dedicated tab for the one I do use.
Anyhow, I start by setting all the sliders to 0 except for Color. I can't see it doing anything and my philosophy is that if I can't see what it is doing there isn't any point in changing it. After setting them all to 0 I start applying them in very small increments. Normally I don't get any slider much beyond its label. This one is an exception for the Luminance slider. I did have to set it pretty high compared to what I normally use.
That's not the problem though, it's the Detail and Micro Sharpening sliders that are generating all the noisy artifacts I'm seeing. I reset them as shown below. You might try my settings and see if it percolates up through the editing stack to affect the artifacts you are seeing from that Local Adjustment to the bird. 9000 ISO can do that. 😀
Oh, BTW, when I first tried to add that screen shot at the top of this post I got the error message about not being able to do that. I force reloaded the page and it worked then.

Thanks for the help, Brian. I apologize for not getting back to you sooner. My work life took over.
I realize the sharpening was a bit overcooked. I am hoping to put this on a large canvas and made the assumption that it will look a bit better when the picture is printed. I'll give your suggestions a try.
I'll also load the image on my laptop since it has a much better graphics card and a more recent driver update.
I hadn't thought about reloading the page when trying to insert an image in a post. I'll give that a try the next time.
Thanks again!

Hang on until the same thing if you can. I have some contacts in regards to what you said about sharpening and printing analysis, but I can’t get into that right now because I am driving. I will write it up this evening when I return from Las Vegas.

That sounds great. It turns out I'm leaving this weekend for a business trip to Las Vegas.
I think the issue is video card drivers. I didn't see the artifacts at all on my laptop.

I think that's probably the problem as well.
On sharpening. There are 3 kinds of sharpening.
Presharpening — This is what NoNoise AI and Tack Sharp AI are for. There is an inherent softness to digitally captured images because of how the sensors break up the light for each photo cell. This is to compensate for that.
Stylistic sharpening — This is for helping to direct your viewers eye. Points of focus should be sharper, outlying distractions not so much maybe. This is where the Sharpening filter fits into the picture.
Finally, we have output sharpening — This is where you sharpen for the media the finished image is to be displayed upon. Canvas will require different sharpening than paper and each of those needs it because the ink will bleed into the paper/canvas. Metal prints don't need as much as there isn't the problem with the ink bleeding to soften the edges like the organics. Monitors need a different sharpening than prints. This is what the sharpening settings in the Export and Resize panels is for.

That's good info. I'll start over with the file on my plane ride this weekend and see what I can do differently.
Thanks!
