How do I create a brush that fades out opacity based on brush speed?

[Dave_Draws]

I am trying to create a brush stroke similar to the one in the image.

The stroke starts at the bottom, where pressure determines brush size only.

At the top, I flick the pen upwards, and as I do, the increased speed of my movement causes the brush to fade out.

I have tried various settings, and maybe I'm missing something obvious, but I have not been able to create this effect.

Is this possible in Photoshop?

I don't know how to control opacity with speed — not even with Lazy Nezumy Pro — but in Brush Settings > Transfer set control to Fade.  You'll need to set the Fade value according to your expected brush stroke.

But what you can do with LNP is invert pen pressure controls size so that the harder you press the small the stroke.

Thanks for your suggestions. Unfortunately, not quite what I'm looking for.

I have discovered that Adobe Fresco has a velocity slider on some tools that allows control over flow, and it would be ideal if that same feature was available on Photoshop tools as well. I suppose I need to suggest it on Adobe's feedback system.

Yea, nothing like that in PS, now. As you mentioned, post it in the feedback site: https://feedback.photoshop.com/photoshop_family

Thanks for the link! I've put in my suggestion.
