A technique often used in advertising these days, is these glowing lines. They look like light motion trails. If you ever wondered how to create these kind of lines, here is how I do it…
Draw a nice thin curved filled line in Photoshop using the Pen tool.
Double click the shape layer on the right to activate the Effects. Check the Outer Glow option and play with the color, transparency,… That’s basically it. I think the hardest part is finding the exact setting and drawing the exact line you want.
