Fisheye Effect using Photoshop CS 2 or CS 3
First you must read this link about the fisheye lens – but if you already know about what is fisheye lens or fisheye effect you can skip that link. If you search on google about fisheye effect using Photoshop – you can find that the common way to make this effect is using spherize. Because I don’t have a fisheye lens so I try to edit my photo using spherize effect. From my point of view this method isn’t good – later you can see my explanation. What is the special abilities of fisheye lens?…. this lens has special distortion – actually we don’t want distortion in our lens but for fisheye lens is different.
Now before I explain how to edit use photoshop CS 2, you need to go download the distortion picture for 35mm f/1.4L USM and 15mm f/2.8 fisheye. You need to use at least Photoshop CS 2 because some filters aren’t available in Photoshop CS. You can see EF 35mm f/1.4L USM distortion and EF 15mm f/2.8 fisheye distortion below:
After that use photoshop to make the layers structure become like this – copy the first layer (35mm f/1.4 distortion) and put it above the second layer(15mm f/2.8 distortion). Second step : you need to change the opacity of top layer (35mm f/1.4 distortion copy) become 50%. Then you will see layers structure become like this:
Now you can use spherize effect – from menu Filter->Distort->Spherize. Then you can set the value – in my example I use 25% and the picture become like this:
You can see that the distortion line after using spherize effect isn’t same with the 15mm f/2.8 distortion line – thats way I think this method isn’t very good. Because I think this way isn’t good so I try to find other way – in Photoshop CS 2 there are new filter about lens correction. Most people use this filter to correct the distortion of lens – but what I need is not to correct the distortion but to make the distortion. The way is very easy – you need to copy the bottom layer and put it into the top layer then you click Filter->Distort->Lens Correction, after that you just change the remove distortion value become -20. After that you change the opacity of the top layer become 50% and you can see like this: (the distortion line isn’t precisely same with 15mm f/2.8 but it’s very close)
After that I use my graduation photo to test it. You can see before and after – sorry I also provide other post processing about the color and contrast – but you can compare the distortion between 2 photos.
Other example – the original photo before fisheye effect can be seen in this link.
I hope you like this tutorial – any suggestions or comments are welcome.
