I wanted to mess with the UV editor a little bit so I thought of a quick thing I could make to help me out. Basically, I would like to take a picture of a box, the top and sides and then just put them on a good old primitive cube. However, when I take the picture it seems like there are rounded edges. I remember reading a post, I think from Prodigy about some kind of barrel effect or something. Any ideas on what I can do to fix the distortion and make it nice and square? |

the distortion is caused by the lens on your camera. Cameras with zoom lenses usually have more distortion at the far and near ends of the zoom. Telephoto (far) tends to have less distortion than wide-angle (near).
There's also some filters in your paint program if you use GIMP or PhotoShop that can reduce the distortion and straighten up your image.

Alternatively, PaintShop Pro also does this.. - I'm still using 8.1, which, nevertheless, handles it nicely. |

Thanks for the information Jack and Butterpaw. I'll have to do some digging in Photoshop to find that little feature. That should make things a lot easier. Is there anyway for me to do it while taking the picture? |

Yup. You can avoid the distortion by finding the sweet spot on your lens. Usually it's somewhere near the middle of it's zoom. |

Perfect, I'll give that one a try, thanks! |

You can remove the distortion in PS with a plugin like PTLens (15.00 usd), or you can do it manually with the lens correction filter... PTLens does it fairly painlessly, I think the lens correction filter came in at cs2...

there also some freeware filters by Richard Rosenman here, he mentions the applications that the plugins are compatible with.

Thanks for the great link, those are some nice plug-ins and I was kind of floundering with fixing the picture too. So thanks Rich, I'll be sure and try the built in corrector until I can check out those plug-ins. |
