Hi

I have recently purchased Affinity Photo and I am enjoying it.

I have a question.

My wife is a stained glass artist and from time to time she has pictures that need to have the colour removed in order to create line art to use as patterns.

What is the best way to remove the colour and leave an outline for the pattern?

Hello Bill

Welcome to Affinity Photo :-)


This is what I tried: set the photo to black and white (in adjustments) and all the colour sliders to the right.

Or: set the photo to black and white, then go to 'brightness / contrast' (also in adjustments) and set them to 100%.


If anybody has another solution but no picture at hand: feel free to use

Thank you for your reply.

That works for the most part but it still leaves some residue.

 

Even if you apply a threshold adjustment so that you only have black and white with no shades of grey in between, I don't think any raster effects or adjustments are going to give you clean lines without quite a bit of manual work.

 

I want to be able to create SVGs.  I don't have Affinity Design so I don't know how well it does tracing.

 

Affinity Designer doesn't yet do auto-tracing at all.
