The easy way to make a gradient is to adapt one of the existing gradients.
Be sure to check off as you go along.
2) Select the Foreground to Transparent gradient from the Gradient Picker palette, as described in the first section.
3) Click Edit in options bar/Tool Options.
The Gradient Editor window will open.
The box-like shapes, above and below the gradient in the window, are called stops.
The stops on the top change the opacity of the gradient.
The stops on the bottom change the color.
Below the gradient, you can see that the opacity for this stop is 100%, and its location is at 0%.
The gradient no longer starts as a solid black, but as a more transparent black.
The gradient now starts at an opacity of 50% at the first opacity stop.
Then, it drops quickly to an opacity of 25% at the second opacity stop.
Finally, the gradient fades more gradually to an opacity 0% on the far right, at the last opacity stop.
The above gradient started with black because black was the foreground color.
You can change the foreground color to another color before you create a gradient with the new color.
Or, you can do the following.
You can see that this color stop is black, and it's location is at 0%.
Or, double click the color stop.
If you haven't already done so, go to Color Picking.
Here, red was selected.
The gradient now starts with red and fades to black.
Or, double click the color stop itself, to open the Color Picker window.
Here, blue was selected.
The gradient now starts out with red, changes to blue, and ends with black (the color stop at the right end is still black).
To delete a stop, click it, hold, and drag it away from the gradient.
Or, you can click a stop, and click Delete in the Gradient Editor window.
In the previous sections, gradients were applied to a Levels adjustment layer, and to selections.
You can also use a Gradient Fill adjustment layer.
To save a gradient that you created, do the following.
15) Click Edit in options bar/Tool Options to open the Gradient Editor window.
The icon for the new gradient appears in the Gradient Editor display.
If you click Save instead, a window will open for saving the entire library of gradients under a new name, such as Untitled Gradients.
