Do you use a wide-angle lens? Then you need PTLens!

By
Real Estate Agent with Keller Williams Realty

I admit it ... I don't have a really wide-angle lens - I use the 18-55 mm lens that came with my Nikon D60.  But I still need PTLens ... why?  Pretty much any lens will have some distortion when it's zoomed all the way out.  Look at this photo that should toggle betweeen the before and after photos ... the only difference was correcting the distortion using PTLens:

Okay, the animated gif file doesn't work ... here's the after photo:

The effect is subtle, but noticeable.  PTLens will not only automatically correct the lens distortion, but allow you to correct vertical and horizontal distortions, rotate, scale and vignette.  Remember, these photos were taken with an 18-55 mm lens.  If you're using a really wide-angle lens (10mm to 14mm), you need to use PTLens.  You can get a free, 10-photo trial download here:  http://epaperpress.com/ptlens/.

I have no financial or other interest in this company - I just think it's a really great product!

Glenda - I have a camera that shoots at a 23mm wide angle. I think it shows much more of the room without distortion.

Glenda, Thanks for the tip.  I have been using Photoshop to straighten some photos.  I will have to try this.  My feeling is that the more you can show in a photo about a listing the better -- unless it is distorted.

Robert,  I just looked at your blog and the photos of the condo look distorted to me -- I think they would be much more appealing if the lines were straightened.

Glenda: This is food for thought. I use a 23mm Kodak V570 camera. I never considered the distortion but I can definately tell the difference in your photos.

Hi Glenda,

I use Photoshop for correcting all of my barrel distortion, verticals, etc. But I've heard that PTLens is an excellent program, and can do corrections specific to the type of camera or lens you use. I'll have to give it a try. Thanks!

An, there is a subtle difference but take a look at the neighboring houses on either side of the shot - see how they're leaning in toward the subject property in the before photo?

Thanks, Angelia - the main difference is probably in correcting the vertical lens distortion.  In the before photo, the house seems to be falling away.  This can easily be corrected in PTLens - actually, the vertical distortion is easy to fix in Photoshop Elements, but PSE can't handle the barrel distortion as well.

Thanks, Connie!  I have a side business doing real estate photography for other agents - if you ever need professional photos, call me!

Robert, you may be so used to seeing the distortion that you don't even notice it.  Download a free trial version of PTLens and try it on a few of your photos.  I'm betting you'll see a difference.

Gary, Matt and Michael - I've been using Photoshop Elements for years to correct vertical distortions, but didn't realize how much barrel distortion was still present until I corrected it.  As Michael notes, PTLens corrects barrel (or pincushion) distortion specific to the type of lens you're using - much simpler than trying to do it in Photoshop.

Hi Glenda! I've gotten the trial version on PT Lens since you mentioned it to me in Flickr, and it really does give an added sharpness to the image that wasn't there before. Most people won't notice the distortion until they are trained to see it, but they will notice that extra crispness in an intuitive way. Thanks!

You're welcome, Jim!

I'm so glad you found it useful, Deena!  I use it on every photo ... sometimes the differences aren't very noticeable, but sometimes they're quite dramatic.  And at just $25, it's a bargain!

Glenda:

PTLens is an excellent product, and it is the first step I use when importing any image over after preprocessing in Camera RAW.  The GREAT thing about PTLens is that it has algorithmns for most every DSLR and lens on the market.  Since most image data is captured in metadata, PTLens uses that information and pulls from its database to correct the image distortion properly based on the equipment used in the shot.  You don't need to make the adjustment, the software does it for you.  So, if you switch lenses during a shoot, PTLens will recognize that and make the changes based on the distortion values of each lens.

The Panasonic cameras with a wide angle lens already correct for distortion in the camera but for others PTL works well.

Nice examples.

If you are a photoshop user, you can correct barrel distortion in PS. You can also correct verts and rotation issues there. The newest PS, CS4 has a few new features that let you do it all right there. PTLens is good and very automatic though so if you are not too techy, it might be the best alternative for you.

Christopher, I understand PSCS4 is very good at handling the distortion (I still have CS2), but it does require a lot more tweaking on the part of the user.  And PTLens is only $25 ... slightly less than Photoshop :-)

And the really wide angle lenses like the Sigma 10-20 can have a "moustache" distortion that PS and PSP can not easily fix.  But PTLens can do it.

Like you said the effect is subtle but noticeble. I'll have to dig a little deeper. Btw, I hate distortion.  : )

That is very cool Glenda. I understand that the latest version of PS has a anti-distortion function as well.

Im wondering if when using PT Lens and HDR (while stacking the pictures) will it effect the final process....
