I want to emphasize a word in a sentence. I've seen it somewhere but couldn't find the picture. Its like the selected word is normal but all other things are blurry. And maybe the word is closer than the rest. Any tutorial or tips on doing this?
In Photoshop, you can manually create a blur effect in everything surrounding your image using the Blur Tool.
Rasterize your text so you have a bitmap image of your text.
Duplicate your layer (to keep the original safe!)
Select the Blur Tool, choose an opacity of 30% or so, and a brush size of 40px.
Start blurring your image from the outside in. First do the borders, then surround the word you want to keep on focus.
Repeat the strokes until you achieve the illusion of depth (so the borders are more blurred than the middle).
You're question could benefit from further info (available software, intended use, what you've tried already, etc). Nonetheless, I'll take a shot.
Set up your main text and duplicate the emphasized word over it.
In Illustrator, the most controllable option would be to apply a feather to the text (
Feather). Depending on the size, it won't take much: Consider how thick the strokes of your font are. Other blur effects in Illy or Photoshop would work too.
Your emphasized word will remain un-feathered and, thus, emphasized. You can play up the difference by scaling it up or using a darker/brighter color.
I would recommend wiping out the emphasized word in the original text and inserting the necessary clear space in it's place.
