To add a Solid Fill Layer, we click the Fill Layer Icon at the bottom of the Layers Panel. Next we click on Solid Color at the top of the pop-up menu. When the Color Picker Panel appears select Black. This is usually a good starting place and easily changed later on.
Our final step in this project is to sharpen the image. An easy way to do that is to use a High Pass Filter.
First, we have to create a new layer for the filter. We can do this by right clicking on the Flower Layer in the layers panel and then choosing Duplicate Layer near the top of the pop-up menu.
So, with the new layer highlighted, select
Filter > Other > High Pass
This will change the appearance of the flower to a gray color and an adjustment window will pop-up, as shown on the left side of Figure 74. A good rule of thumb is to start with the slider all the way to the left and then slowly move it to the right until you can just barely see the details in the sample window of the adjustment panel. You may want to experiment with more pronounced details to see the difference.
