There are a few different ways that you can create a spark effect in Photoshop. One way is to use the Pen Tool to draw a path, and then use the Brush Tool to paint along the path. Another way is to use the Clone Stamp Tool to clone parts of an image that already contain sparks.
To create a spark effect using the Pen Tool, first create a new layer. Then, use the Pen Tool to draw a path on the new layer.
Once you have drawn the path, select the Brush Tool and choose a brush that has soft edges. Paint along the path that you drew with the Brush Tool, and then set the layer’s blending mode to Screen.
To create a spark effect using the Clone Stamp Tool, first select the area of an image that contains sparks. Next, choose the Clone Stamp Tool and set the brush size to be slightly larger than the area you selected.
Hold down Alt and click on the area you selected to clone it. Then, click and drag the Clone Stamp Tool over the area where you want to add sparks.
