Filter: Unsharp Mask preview after resample crop


Recommended Posts

Maybe my fault, but the result of the Filter Unsharp Mask is not the same you see in the preview of the filter after a resample crop.

1. I cropped the image a bit (resample). Additional question: Why do we have no option for the resample methode like Bicubic, Bilinear, Nearest Neighbor etc.?

2. I opened Filter Unsharp Mask and preview was showing what I wanted.

3. After hitting "Apply" the result had nothing in common with the preview.

It is another usability issue. You have best quality (bilinear) selected in preferences, performance. What you see before unsharp mask and after is probably correct.

Photo toggles away from best quality (bilinear) to Nearest neighbour while the unsharp mask options are on screen. So you are sharpening with one performance setting and working with another. What you see is totally different.

So which one is the most accurate. Best quality looks like what I see in Photoshop.

Besides a usability issue it is a totally useless implementation. I reported this - and Serif couldn't reproduce it!! - a long time ago before I shelfed photo for anything but adding effects to drawings from Designer.

When I change my preference from "Bilinear" to "Nearest Neighbour", preview and result are also different.

Correct.

No one else noticed, LOL?

Maybe I am not good at writing meaningful topic subjects / titles?

Besides you and me I did not notice any other posts about it. Ever. And sharpening is key in photo processing. I noticed this bummer immediately the first time I tried using unsharp mask in Affinity Photo.

The Crop Tool in the current app never actually resamples objects. Its "resample" mode can change the pixel density of the document in addition to resizing the canvas, but Pixel objects get non-destructively scaled rather than resampled.

The preview of a filter being applied to a non-destructively scaled Pixel object (see my previous paragraph) is misleading. See my explanation here:
