You can use the Add Text tool in Edit mode to add formatted text to a photo, or add talk and thought bubbles to create a comic-book effect. You can also adjust the opacity of the text to create a watermark effect, which is useful for putting copyright information onto your photos.
You can save your settings as a preset for future use.

                     Effect  | 
                
                     Specifies the effect you want to apply to your text. Each effect has different options that control its appearance. Drag the sliders to adjust the appearance of the text.  | 
            
| 
                     Drop Shadow Settings  | 
                
                     Distance  | 
                
                     Specifies the distance between the drop shadow and the text. The higher the value, the farther the shadow and the higher the text appears. If a drop shadow is cut off, or has a noticeably sharp edge, you may need to increase the size of the text rectangle.  | 
            
| 
                     Blur  | 
                
                     Specifies the amount of blur applied to the drop shadow. Sharp shadows tend to seem less realistic than those with a slight blur.  | 
            |
| 
                     Opacity  | 
                
                     Specifies the darkness of the drop shadow where it falls on the image.  | 
            |
| 
                     Angle  | 
                
                     Specifies the direction of the imaginary light source that creates the drop shadow. Drag the arrow to adjust the angle — note that this also adjusts the shading of the text bevel.  | 
            |
| 
                     Bevel Settings  | 
                
                     Bevel  | 
                
                     Specifies how much of each letter's edge is bevelled. Higher values give the text a more rounded, smoother look.  | 
            
| 
                     Strength  | 
                
                     Specifies the difference between the highest and lowest points on the text. Higher values heighten the difference between the flat portions of the text and the bevelled edges.  | 
            |
| 
                     Elevation  | 
                
                     Specifies the height of the imaginary light source that creates the bevel's shadowed effect. Lower values produce longer shadows on the text, while a higher value produces a more direct lighting effect and shorter shadows.  | 
            |
| 
                     Angle  | 
                
                     Specifies the direction of the imaginary light source that creates the bevel effect. Drag the arrow to adjust the angle — note that this also adjusts the angle of the drop shadow.  |

                     Add text as a new layer  | 
                
                     Select this checkbox if you would like your text to appear on a new layer in the Layered Editor.  |
