How to fix big center photo?

[Rexkh]

Dear Member

If I take a photo of document too close, the text is big in the center and small at the edge, the line at the edge is also curve. Please take a look at a photo I took as an example in attachment. Is there a way to fix it in Photoshop or others application?

Thanks in advance.

Are you asking if the pieces missing or the letters missing can be replaced not sure I understand

The effect you are seeing is called barrel distortion:

There are numerous ways to substantially reduce it. For example, in Photoshop, you can correct it either in ACR or in the main body of PS. To do it in ACR, see:

In addition to the built-in, native tools, numerous 3rd party plugins such as Power Retouche Pro can correct for this problem.

Yes, Tom, that's it. I just don't know how to call it. Sorry for poor explanation. I'll try to do it with the tool you mention. Thank, Tom, for your valuable information. And also thank to iDad for contributed discussion.

You can find the Lens Correction Filter under the Filters Menu in Some Versions of Photoshop CS5-CS6 ...and in Earlier Versions under Filters> Distortion> Lens Correction.

By making a Background Copy, You can apply the Filter and Then Save You Document as a PSD. File or a Jpeg.
Your Original Photo Will fill in the Background when or if You choose to Flatten the Image.

Take Care,
