You can enter or format type as uppercase characters, either all caps or small caps. When you format text as small caps, Photoshop automatically uses the small‑cap characters designed as part of the font, if available. If the font does not include small caps, Photoshop generates faux small caps.
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.
