Changing case
You can enter or format type as uppercase characters, either all caps or small caps. When you format type as small caps, Photoshop and ImageReady use the small caps designed as part of the font (if available). If the font does not include small caps, Photoshop and ImageReady generate faux small caps.
To change the case of type:
- Select the type that you want to change.
- Do one of the following:
- Click the All Caps button
or the Small Caps button 
in the Character palette. - Choose All Caps or Small Caps from the Character palette menu. A check mark indicates that the option is selected.
Note: Selecting Small Caps will not change characters that were originally typed in uppercase.
