Defisheye Using Adobe Photoshop CS 5

This tutorial is an extension of my previous tutorial…. the main difference just the software, in this tutorial I will try to compare some methods (of defisheye) by using Adobe Photoshop CS 5. You can directly read this tutorial but I think it’s better to read my previous tutorial to get some idea about my previous experiment.

Maybe you’ll ask me “Why I write this tutorial?” Honestly one of my friend ever ask me, which one you will buy: wide angle lens or fisheye lens? Well, my answer is “Depends on what you want to shoot… ~ if you work for documentation I think it’s better to use wide angle lens, but if you want to play with creativity I think fisheye lens is a good choice. Then my suggestion: you can buy both of them so you can change the lens depends on the situation but I forget to consider how much money will be spend to buy both of them hehe….. Well, another option is buy one of them, if you buy wide angle lens then you can use Photoshop to add fisheye effect on it (see my previous tutorial about fisheye effect) or you buy fisheye lens then defisheye using Photoshop (if you need a normal photo). This tutorial covers the way to defisheye a fisheye photo using Photoshop CS 5.

First you need to have a fisheyed photo, in this case I use this photo (taken with 5D II and EF 15mm/2.8 fisheye):

Then using Photoshop you can copy the layer (Ctrl + J) so you can edit the photo without destruct the original photo… the next step is go to Filter>Lens Correction (Shift + Ctrl + R) and dialog box will appear…

Adobe Photoshop CS 4 has lens correction features but it’s a little bit different with Adobe Photoshop CS 5 ~ and the part of dialog box (above) only can be found in Adobe Photoshop CS 5. From that dialog box, you can click on Geometric Distortion and Photoshop will fix the distortion easily.  The result is like this one:

You also can click on Auto Scale Image and the result will be like this one:

Both of results are good, first result is more natural than second result ~ but second result has great corner effect (like a lensbaby result hehe….). But wait…. I will show you some result from others method (I already explained these methods in my previous tutorial.)

Using Warping Transformation: (for more explaination please read here….) ~ this method is so simple,  you can use Edit>Transform>Warp. Then you can move the points to create like the picture below…

The result (after trial and error):

The other way is to use FisheyeHemi (plugin for defishing your fisheye photo), it’s very easy to use but you need to pay extra money for getting the plugin. The result is like this one:

After comparing 4 methods, I try to give some conclusions….

1. FisheyeHemi produce the best sharpness among the other methods but it is a plugin (that means you need extra money for it, and of course you can do this only in installed computer not in every computer). Other methods results not very good (in terms of sharpness) but you can deal this matter by using unsharp mask….

2. Warping Transformation method is very flexible, we can adjust the points so it can fix other problem (not only fisheye photo but also to fix distortion from wide angle lens). Although it is flexible but it also difficult to precisely obtain the best result. This method also produce the worst sharpness among others…. The other advantage is you can use previous version of Photoshop (no need to install Photoshop CS 5 or plugin).

3. Photoshop CS 5 lens correction (geometry correction with/without auto scale image) is good feature but it loss many parts of photo (especially in the corner). There is no any parameters to be adjusted to reduce the loss part…

I must admit this new feature in Photoshop CS 5 is great, it can fix the problem quickly and easily….. I hope this tutorial give you some ideas ~ comments are welcome…..

    • Agree…. but the difference thing is when you need to use filter for your lens ~ fisheye lens has no place to put the filter so you need to create a special holder for the filter hehe….

      • hmmm…true. What if, we buy ultrawide lens and apply fisheye effect on PS later on post processing (if we need it) instead than buying fisheye lens and defisheye it???which one do you prefer?

    • I think it’s better to buy wide lens then apply fisheye effect on post processing…. the reason is “fisheye is good for special photo, but for daily photo (documentary and general photo) we don’t really need it”.

  1. OMG, I tried the free trail of the plug-in……..it is so good. I hardly see any image degration at cornor. very minimal.
