4. Select the Gradient Tool: On the left-hand toolbar, select the "Gradient Tool".

5. Choose the Gradient: In the options bar at the top, click on the gradient to open the gradient editor. Choose the "Foreground to Transparent" preset (usually the second option).

6. Set the Colors: Set the foreground color to black and the background color to transparent.
