No Units in Filter Dust Removal

[Peter2017]

Hi! My first Topic here! I'm a little bit nervous...Let's have a try.

Having Win 10 (German Version) and Photo Beta 1.6.3.99. When using the filter "Dust Removal" (Dunst entfernen) I see no Units, like % or Pixel. It isn't useful. Can anybody follow this?

Sorry, if this was mentioned before. I didn't find it in the "Search"-Area.

Thank you for reply.

Greetings

Peter

Hi, Peter. Welcome to the forums.

I don't see a Dust Removal filter (though I can find Dust & Scratches). According to Google Translate "Dunst entfernen" is "Remove Haze", so perhaps Filters->Haze Removal is what you mean?

If I select that, I get a popup window with several sliders to control the effect. You're right that none of them give a Pixel-based size setting, but I don't think that's what Haze Removal is intended to do. More information about what it does is available in the Affinity Photo Help. Just search, probably for Dunst entfernen In the English help it says

Quote

Haze Removal can remove slight to extreme cases of haze affecting an image. Its most typical use is for landscape photography where the haze causes low contrast and low saturation, but it can also be used to improve images taken during rainy and foggy conditions.

Settings

The following settings can be adjusted in the filter dialog:

• Distance—controls the depth of the haze removal: moving the slider to the right removes haze towards the background of the image.
• Strength—specifies how strong the haze removal effect should be. More strength results in more extreme haze removal.
• Exposure Correction—allows for correction of the image's exposure: use if haze removal causes underexposure or overexposure.

If you are interested in dust, not haze, you might want Filters->Noise->Dust & Scratches...  or Layer->New Live Filter Layer->Dust & Scratches Filter. Either of those will give you a radius setting, which seems to be what you're looking for. But I think the Dust & Scratches filter and the Haze Removal filter do very different things.

Thank you for welcome and your help That's what I mean. "Remove Haze". Of course. My translation was too "German-minded". Thank you.

But nevertheless - I think, in a workflow it ishould be better for comparability, to have a Pixel-based size setting or %. Perhaps it is a feature and not a bug...

Great. I never saw and used them before. But you're right. They effekts a little different things. 

 

Thank you and best regards

Of course - I meant these filters. Remove haze - that's it! My translation was misleading. Sorry! But nevertheless - there were no units like % or px, are they? I think, it's a little annoying feature - not a bug.
