black and white conversion of picture (Affinity Photo desktop) i mean way where if colour is darker than given colour is goes black and if is brighter this colour goes white? i have old program what i can use technically at least small images to do it. but if i hoped i can do it modern tool faster and bigger images.

Threshold Adjustment

not fully same (in other i can use rgb values for such level). but many cases even this is fine.

The "Black and White" adjustment lets you influence colour ranges, optionally with a Colour Picker Tool. If you want to avoid gray but achieve black/white only you could combine it with a levels/curves/contrast adjustment if.

The "Channel Mixer" adjustment lets you influence black/white by intensity.

good ideas what allows little more flexibility.
