The Photoshop "Straighten Tool"?
Wide-angle photos have a confusing number of lines.
Which one should be used for straightening the image? One in the very center perhaps? |

Not all editions have all the correction tools that later editions have. Are you working with RAW or JPEG files? Some corrections are better made with RAW files, and some tools might not be available to JPEGs. There are several methods of correcting wide-angle lens distortion with Photoshop and/or Lightroom. Sometimes, if you are lucky, just having a correct lens profile can correct non-extreme distortion provided the FL is not too extreme. If you are processing RAW files then you would start with ACR or Lightroom, and use the Lens Correction tools, Transition with guided correction. This is probably the most effective correction for wide-angle lens distortion. There is the Adaptive Wide Angle Filter which can Auto correct if there is a matching lens profile, or the manual Perspective correction which requires some understanding how the filter is used. You also have options for Fish Eye lens correction, or full Spherical correction. Using the Adaptive Wide Angle filter, manual Perspective correction you can use any number of distorted line which should be straight for correction. Understand that with an Ultra Wide Angle lens the greatest distortion is going to be away from the center line, and over correction can induce unwanted distortion of straight line in the center of the image. Good Luck. -- Regards, Savageduck |

Do you want to straighten a vertical, or horizon in the image, or are you trying to fix diverging/converging lineds due to WA lens distortion? If all you are trying to do is fix a horizon, or straighten a vertical, then use the straighten tool on a horizontal line, or a vertical line closest to the center. Just understand that none of the WA lens distortion is going to be corrected. Also with either straightening, or distortion correction there can be data loss at corners, and/or edges, which can be fixed if you check the “Constrain to Crop” box, or use auto fill. The Transform tool (in ACR lens correction/Lightroom Transform) will actually do a much better job of straightening. I would suggest that you check on some of the video tutorials which are available on this subject. -- Regards, Savageduck |

That is OK, but if you have Photoshop and/or Lightroom available it is best to get an understanding of how the most commonly used tools are used, and one of the best ways to do that is to take a look at some of the many video tutorials. Those will give you a good idea of when to use those tools, and some insight into some of the intricacies. Youtube can be a good source, otherwise I recommend taking a look at videos from Julieanne Kost, Matt Kloskowski, and Terry White. http://blogs.adobe.com/jkost/photoshop-training-videos https://www.youtube.com/results?search_query=julieanne+kost http://mattk.com/category/photoshop/ Terry White deals in all things Adobe, so a little digging for Photostop specific stuff is needed. https://www.youtube.com/user/terrywhitetechblog I included these in a response to PeterN: https://www.youtube.com/watch?v=LMm0AD9Brp8 https://www.youtube.com/watch?v=Vjg4RtV4UAk https://vimeo.com/205460101 https://www.youtube.com/watch?v=ywmOWmkSv7o ....and if you are using Lightroom: https://helpx.adobe.com/lightroom/ho...ection-guided- upright.html I'm just a snapshooter at family functions, and I specialize in candid shots. So you are one of those guys responsible for those embarassing Thanksgiving and Xmas shots. ;-) Also in correcting downloaded sundry images.

It all takes hours & hours. That is of course a totally different task than the one posed in your OP. However, even for that there are tools which will make things easier. For example, the Vanishing Point Filter can make the placement of objects such as windows, shelves, etc. simpler, especially if you need to maintain proportions, and perspective. https://www.youtube.com/results?sear...er+photos hop +cc -- Regards, Savageduck |

I your camera and lens is listed, The ACR filter has a setting for automatic adjustment. As nospam suggested, You can also use the WA adjustment tool in PS. I ordered a boxed DxO ViewPoint 3 today, almost half price compared to their website. I'm very happy with the trial look forward to have access to it in Photoshop and Photoline on a longterm basis. -- teleportation kills |

If you were able to buy it cheaply you can look forward to an upgrade in the near future. DxO does that. -- Regards, Eric Stevens |

It's out of stock but worth waiting for: http://tinyurl.com/ybtwvr8p The trial still works and I have the v1 installed but cc2018 broke that. It , v1 still works as a standalone though... -- teleportation kills |

I have an old version of Viewpoint. I use it so rarely that i did not update it. I found the adjustments in PS worked just fine for my purposes. YMMV -- PeterN |

If you use PS CC and/or Lightroom Classic CC you should try the Guided Upright correction available in ACR (both initial ACR processing Camera RAW filter in PS), and LR in the Develop Module in the Transform Panel. In PS CC ACR select the Transform Tool, and then Guided Upright. https://www.dropbox.com/s/rnc0citq9svn56a/screenshot_297.png LR CCC is similar, but accessed via the Develop Module, Transform Panel. https://www.dropbox.com/s/z6bknaogcf8ool5/screenshot_300.png -- Regards, Savageduck |
