Staring out this image, I used a portrait i had taken and made it slightly darker to suit the tone of the neon light i wanted to add.
Selecting the brush tool I adjusted the size to how large i wanted the neon light to be and with the pen tool i drew out this shape, right clicked and selected Stroke Path to create the shape. Afterwards I added layer effects to get the general neon colour
I then selected my subject and selected the grouped layer containing the stroke paths and masked it, this caused the line to appear behind the subject, which i used the pen tool on the mask to bring back to the front to give the illusion it's going around the model.
I used the brush tool again to adjust the size of how i want the hue radius to be, and applied it as a stroke path and blended it into the image. I added a hue and saturation adjustment layer, making sure to select colourize to adjust the hue and saturation and ensure that only the highlights were reflecting the light (done on layer options > blending options)
After some more adjusting, this is the final image. I'm quite happy with how it turned out as this is my first time doing a complicated composite such as this.
