How do I make a piece of my picture glow, I've already tried putting a brighter shade of the same color next to it and blurring/smudging it but that doesn't look good at all. Help please.

Which program are you using?

/\ brightness, \/ saturation, then just make it act in the same way as light.
When you highlight it highlight it up to white isntead of just a lighter colour.

As for the object you need to highlight to the center, then out to the edges, so both the edges and the center are bright. That should make it glowy

thanks
