Inpainting Brush Misbehaving

[alan_hodges]

Today the inpainting brush is driving me mad. I'm working in the Windows version with all drivers up-to-date. My image is black and white and peppered with small white blemishes  which I'm trying to remove. Usually this brush lets me move from one blemish to the next very quickly but, today, it insists on displaying the inpainting progress dialog every time, slowing me down by a factor of about 7 or 8 per blemish. Worse still, now and again, I click on a blemish with the brush and it goes off on a frolic of its own, drawing a red line diagonally across the image and ending at the click point. The progress bar appears and I wait for well over a minute for it to do its stuff. Then it's press <CTL> <Z> to remove its depradations.

It's never behaved like this before and I'll be grateful to anyone who can suggest a solution.

Are you holding any keys down by accident when using the Inpainting Brush? Do you only have the one layer or multiple, is the correct one selected?

[alan_hodges]

Thanks Lee D. No, I haven't been holding any key down when using the inpainting brush. After posting yesterday, I saved the image (with history) and then processed several other images without the problem repeating itself. I've just reloaded the problem image and used the inpainting brush with the very same results. That makes me think there must be something about the image itself which is causing the inpainting brush to misbehave. The image is a Vuescan .dng scan and I have processed dozens of similar scans without experiencing the same problem.

All I have in the layers panel is the background layer, a levels adjustment, a curves adjustment and a high pass filter. I have tried turning off the filter (in case I should have applied it after completing the inpainting) but the problem remains....

That sounds a little like the Stabilizer feature is enabled in the context toolbar.

Regarding the progress bar, what are the pixel dimensions of the document & of the brush, & which brush are you using?

[alan_hodges]

Thanks for the suggestion that the Stabiliser is enabled but I have checked and this is not the case.

The pixel dimensions of the document are 16008 x 961 @ 3200dpi.

The .dng file I started with was 3.2MB but currently the .afphoto file is 2.42GB! I have no idea why the size of the file should have increased so dramatically, especially as I have done relatively little processing to the document.

The inpainting brush is 66.4 px. I have failed to ascertain which brush I am using but, as I have not picked one, it will presumably be the default brush.

Do you really need 3200dpi?

Saving the file with history can dramatically increase file size but that still seems large compared to the original image

 

Are you working on just a single pixel layer or do you have lots of adjustment layers etc?

Those dimensions seem unusual for a scanned document, & the DPI seems much higher than necessary. Can you tell us anything about why those are the document values?

Those dimensions seem unusual for any document! I wonder whether a fourth digit has been omitted from the smaller dimension (which, at the stated DPI, would make the document a reasonable 5″ × 3″ or thereabouts).

What I have been trying to do in Vuescan is to make my scan a raw file as I like to work in the Develop Persona in AP (at least to begin with) and believe I can extract more detail from my negatives by so doing (yes, I know you can work on jpgs in this persona but a jpg scan is lossy). I have not found this easy and there has been much experimentation. This particular image was an early effort and shows that my experiments were not going particularly well at that stage. I regret that I had not noticed the unusual stats. I have now gained a modicum of success with scanning to raw and will rescan the dodgy image.

However, it would be very nice to know whether my poor scan was the cause of my two problems with inpainting.

My grateful thanks to all responders.

You should work in TIFF, which is not lossy. The amount of detail should be the same as working in RAW. (Do not choose TIFF DNG in VueScan; just TIFF.)
