How to make a step wedge in Photoshop
Ever seen one of these? Its called a step wedge and is very useful for embedding
into your web pages and galleries so your visitors can check that they are at least ballpark correct with their monitor brightness.
Here's how its done.
Open Photoshop and go File > New
In the box enter these values :
500 pixels wide and 80 pixels high at 72 dpi.
Select the Gradient tool and while holding down the shift key drag from left to right the resulting banner should look like this:
Now select Image > Adjustments > Posterize Like this:
The Posterize box should then appear with the default 4 graduations, for our purpose this is far too coarse so we will enter 21 into the box:
Click OK then to finish select the rectangular Marquee tool and then place a 2 pixel black line round the outside Edit > Stroke
