Make a realistic shine...
1. Open up a picture where you want to add this effect to. I used a Sith Trooper with a Diecast Metal Armor
2. Select the part you want to shine, and copy it onto a new layer
3. Create a new layer above the (in my case) shoulder-part and add THIS gradient;
4. Make it look like this; (colors must be black, #000000, and white, #FFFFFF)
5. Position the gradient layer;
6. Press CTRL+G and set it to overlay;
7. Hop onto Image-ready and press the following button;
8. Make the 1st frame have a palette like on the left, and the 2nd frame like the one on the right;
9. Press the tween-button and set these options;
10. And this is what it looks like when you've done everything correct:
