A recorded session

Pick a request to replay

The poster in Photoshop before the request: NORTH LONDON FOREVER in red over a charcoal room, a figure standing in front of the type.
Before
The poster after the first pass: the type is yellow, but LONDON and FOREVER are duller than NORTH.
First pass
The poster after the request: all the red type, the glass panel and the glow are now yellow; the figure is unchanged.
Fixed

It checks its own work.

After an edit it renders the document and looks. Here the first pass left two lines duller, so it fixed them before it answered.

“Turn everything that’s red into yellow.”

It animates, then shows you.

In After Effects it sets the keyframes and renders a short preview, so you see the motion before you keep it.

“Make NORTH, LONDON and FOREVER punch in as they land.”

Reference
The result in Illustrator: NORTH LONDON FOREVER as red vector type on charcoal, with the two footer lines.
In Illustrator

It works from a reference.

Attach a poster, a logo or a brief. Here it rebuilt the poster’s title in Illustrator, as clean vectors.

“Rebuild this poster’s title as vectors. No photo.”
