With the help of Illustrator CS3 we are going to learn how to cut text shaped selections out of photos to produce a solid framework.
Create a new document. Place an image of your choice.
Type a text and place it on the image.
Choose both the photo and the text.
Mask them by going to Object > Clipping Mask > Make.
Now you will be able to see the image through the letters.
Add outline and shadows to the text.
It can be used for making logos, banners, etc.
