cosmickid Posted March 13, 2021 Share Posted March 13, 2021 Hi all! First time posting here I'm trying to replicate this Ink Bleed effect in Affinity Photo - https://youtu.be/M_8YGwO9gXg Adding a threshold adjustment doesn't appear to produce the same effect as it does in Photoshop though and I can't understand why? Any help with this would be really appreciated. Quote Link to comment Share on other sites More sharing options...
lepr Posted March 13, 2021 Share Posted March 13, 2021 Put a white Fill Layer (or vector Rectangle) at the bottom of the layer stack. Threshold Adjustment has colour components (e.g. R,G,B), not alpha, as its input and output. The blurred and distorted text is black with varying alpha - it is not various greyscale intensities - therefore it needs to be composited with a background to produce varying intensities to which the threshold operation will be applied. Notice that the Photoshop example has a white background layer. The canvas white of Affinity is no substitute for an actual white background in your exercise because the document layers are composited and then that result is blended with the canvas, and so the canvas has no influence on the values to which the threshold is applied.

You can also try to add other effects. The Affinity Ripple effect seems to work differently than the Photoshop version, hence I didn't use it. Threshold has to be on top. The displacement map image is linked but it's the same image as the disabled one at the bottom. In fact, destructive rasterizing is not even necessary except for creating the group mask. The rest can remain live: Great trick. Every day I'm learning something new.

These are the types of effects us old schoolers still want to be able to do in Photo! Quote Link to comment Share on other sites More sharing options...
