Unsharp Mask Filter - Breakup of Straight Lines

Recommended Posts

Hi, I have attached a screenshot where unsharp mask breaks up the straight lines in an image. The screenshot shows where the powerlines are offset in the Unsharp Mask filter prior to pressing Apply. Note that the image has also been straightened and cropped before Unsharp Mask was applied. Image is a CR3 developed in the application.

Definitely caused by the Straighten function, if the image isn't straightened the lines are correct when viewing the Unsharp Mask.

Are you using the 'Nearest Neighbour' View Quality setting in Preferences?

Hi Chris, No I am using Bilinear (Best Quality) as per normal.

Attached Chris ...EOS M50195493.CR3

Note just switch between 100% and Fit ... sometimes only shows in Fit if there are lots of powerlines in the image. I Guess it could also be related to CR3 processing.
