Is there a simple way to correct the distortion at edges of wide angle photos. I am doing a shoot of a friends home interior, and wide angle is needed to include most large rooms. It would be nice to then correct this distortion. Is there a name to describe/correct this in the various photoshop programs out there. I use program called aperture from Apple.

Thank you

There are tools for straightening out weird angles on buildings, etc. in wide angle shots in Lightroom. From what I know, Aperture is a pretty complete package, I'd be surprised if it didn't have something similar. I learned how to do it in Lightroom by Googling it and finding some Youtube video tutorials and also the Adobe web site has videos. Does Aperture's web site provide anything similar? Also, there might be a tutorial out at B&H or Adorama, they have lots of topics. Hope this helps get you headed in the right direction.

Thank you. Do you know if there is a term for this correction?

PTLens has a plug-in for Aperture. The cost is $25.00, but they allow you to correct 10 images for free.

You are probably dealing with two kinds of distortion. Wide angle lenses frequently have what is called barrel distortion which makes straight lines at the edges bulge outward. (a little like a fisheye lens). Photoshop and Elements have a "lens correction" feature that lets you correct this kind of distortion.

The other kind is caused by the sensor plane not being parallel to the subject. Point the camera upward to shoot a tall building and the top is much smaller than the bottom. This effect is more visible in a wide angle shot. Any deviation from level can cause this distortion. Photoshop and Elements (and I'm sure several others) have "Perspective Correction" tools. You can correct both vertical and horizontal perspective effects.

Be advised that using either or both of these tools warps the image to strange shapes and you must crop to get back to a rectangular image, so include more in the frame than you want in the final image.

Someone else here might fill you in on what other image editors can do these corrections. I am not familiar with Mac image editors other than Photoshop and Elements which have Mac versions. Hope this helps

That was a good video thx. But why don't all these complex software we all buy like aperture and photoshop NOT have such correction capabilities built in?
Seems odd that they would not since they do everything else lol

I got your reply AFTER my above response. Thank you for replying.

My Nikon has a filter in retouch that you can correct barrel distortion. You may want to look and see if your camera does.

Lightroom has tools which do a pretty good job on images from my Sigma 10-20 lens. They are free/included for most of the lenses I use. After using them I can correct converging verticals, etc, as I am sure you can in Aperture. As ronwande noted the perspective correction is a form of cropping, so leave room in your shots for such.

PaintShopPro has a very easy selection for this, called perspective distortion correction. Usually in same area as horizon correction.

I do not use a program called Aperture, I do however use a program called Photoshop and Lightroom. Both come with a 30day free trial. Both offer lens corrections to minimize/correct distortion and "fix" perspective. DxO 8 or 9 also offer up nice tools to correct distortion/perspective problems.

This correction is specific to every the camera-lens pair, so there is an added level of complexity, compared to knowing the characteristics of a camera sensor.

Point and shoot wide angle, barrel distortion and corrected image, using Photoshop Lens Distortion correction tool.

Test shot with barrel distortion


Corrected

Photo taken from slightly above so the camera was pointed down. Kylemore Abbey Ireland inside shot. Again corrected with photoshop.
Elements can do these just as well. Perspective Correction tool in the Lens Distortion filter.
