frand Posted February 26 Share Posted February 26 I use affinity photo 2 (V2.3.1) on a Mac M1. I experimented and searched the internet for hours but could not find an answer to the following problem: I start with a new document and use the brush to draw some arbitrary scribbling with different shades of grey. A new pixel layer is automatically created that holds my work. In the layer panel my pixel layer is selected. I click the "Adjustments" button to create a "Threshold" adjustment layer. The adjustment layer appears on top of my pixel layer. I would expect the threshold adjustment to turn my grey shade drawing into a hard black and white drawing. But nothing happens. The adjustment layer has no effect at all. I tried moving the adjustment layer beneath the pixel layer or tried to group it with the pixel layer, but nothing works. The effect is not applied. When I export my drawing on the pixel layer to a PNG file, start a new document in affinity photo and import that PNG file by dragging it into the layer panel, I am able to create a threshold adjustment layer that is applied to the drawing as expected. This behaviour is very strange and unintuitive. Two questions: 1) What is the difference between a pixel layer that I have created by painting with a brush and a pixel layer imported from a PNG file? 2) How can I make the adjustment layer work directly on my drawing without exporting and re-importing the pixel layer?

thomaso Posted February 26 Share Posted February 26 Hi @frand, welcome to the Affinity forums! FWIW, to me in V1 it appears to work: Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
- S - Posted February 26 Share Posted February 26 The issue is you're not drawing different shades of grey, but different levels of opacity. Therefore, you will need to go to [Layer > New Fill Layer] and add a white fill layer below the pixel layer. Quote Link to comment Share on other sites More sharing options...
frand Posted February 26 Author Share Posted February 26 Ok, I have checked it and you are absolutely right. I did not realize that grey shades and different opacity levels are two different things, although on screen they may appear the same. When I use "genuine" grey shades it works as expected. Thanks for your fast and competent reply explaining this issue. Quote Link to comment Share on other sites More sharing options...
