You can add an inner shadow to any text in your Photoshop document to make it seem like it’s being lit up from the inside. So how you do this is go ahead and click to select the text layer that you want to add the inner glow to. Go ahead and double click anywhere on that layer to open up the layer style dialog box. I’m going to go ahead and move it below so I can see what I’m working on. And then go ahead and click on inner glow and you can see right away we have an inner glow and it looks almost hazy.

Now we could change the blend mode if we’d like to choose a different blend mode. We can increase the opacity to make that to glow even darker or we could decrease it to make it more subtle. We can increase the noise to get those pixels broken up or we can decrease it. We could choose to keep that inner glow at yellow or we can also choose to add a different color if we’d like. I like a deeper yellow. We could also choose to use a gradient if you’d like and you could choose from the different gradients or you could choose to apply the gradient with the yellow. I’m going to go ahead and use a solid color.

We have techniques here and these techniques are much like the outer glow, it’s just—except where it’s applied inwards. So these options are all the same here. You could do soft or precise. You could have it towards the center or from the edge depending on where you want your source to come from. You can increase the choke, make it more dramatic. Increase the size to make that glow bigger. You could change the contour if you’d like to give it a different look. And you can increase the range if you’d like and also increase the jitter. And all these make simple to drastic changes on your inner glow for your text.
