As you may know, Photoshop allows you to apply different text styles to one block of text. This allows you to increase the font size of one character or word, apply bold or italics, or even apply different typefaces within the same block of text.

To do so, choose the Type tool and click in your image document. In the Type Option dialog box, select the text you wish to format. Then, specify a typeface, point size, style, tracking, kerning, or baseline shift. As you apply character formats to your text, Photoshop will preview the effects of your modifications in your image document.
