How to change the eye color in Gimp

Hi! Have you ever wondered how they made a trick changing the color of one’s eyes which looks so marvelous and amazing? You probably ask yourself ‘how did they do that’? Not that difficult really if you are researchful and have interest in the subject. A lot of tutorials are available out there and I’ll show you mine, in a very easy, fun-filled manner.

Ok, sit back, and we’ll start! By the way, if you don’t have a Gimp yet, click here to download your copy.

1. Open Gimp. Go to File menu>Open… Select a picture (face or eye close-up) from your computer which will serve as your subject matter. Above photo will be our sample on this case.

So, we have already the photo on the screen, ready for editing and manipulation, as shown below.

2. Now, go to Toolbox, then select Free Crop Tool (that small ring-like icon on the top-middle). Point over and click your mouse around the eye (your subject) so as to form connected lines surrounding the subject. The Free crop Tool lets you select any region or portion of your subject to be edited.

3. Go to Colors menu>Colorize… In the Colorize dialog box, adjust the sliders for the Hue, Saturation, and Lightness. As you move the slider, you can see the changes in the Preview screen. Freely play and experiment with the sliders until you find the right result you want.

In this case, I set the following settings (Hue:175, Saturation:28, Lightness:2) and came up with the image below as a result.

4. Click Image menu>press Flatten Image…

5. Finally, go to File menu>click Save.

That’s it! Simple as that!

How to make a wallpaper using Gimp

Hello! This time I will show you how to make a cool wallpaper which is really fun and you can make it yourself so easily provided that you have a PC and a photo editing program. I use Gimp here. If you have a Photoshop, that’s better. Check my related post (Free Photo Editing Programs) where you can choose the right program for you to download.

By the way, the above image shown is the finished product which we will tackle here, step-by-step. If you are ready, then let’s get started…

1. Open Gimp. Go to File menu, click New.
Set the template to 1600 x 1200 pixels. Click Ok.


Zoom-out your window to about 30% so you’ll have a better view while you work.

2. Set the foreground (FG) color to anything dark, the background (BG) color to a lighter one than your FG. In this case, I set FG=236f1d, and BG=62e004.

3. In your Toolbox, grab the Blend Tool icon (that small square icon with gradient color), then make a linear gradient to your active window – from top left corner to right lower corner. The result would then look like the image below…

4. Now, in your Toolbox, select the Brush Tool (brush icon), then make a twirling line like the one shown below.

5. Go to Filters menu>Blur>select Gaussian Blur. Set the Blur Radius to Horizontal=30, Vertical=30, then click Ok. The result should be like the one below…

6. Filters>Distorts>Whirl and Pinch… Set Whirl angle to maximum, Pinch amount to 0.500. Click Ok. See below result…


You can save this one now if you want.

7. To make the desired final result as shown here, go to Filters menu again>Distorts>Waves… Set Amplitude to about 40-70, and Wavelength to 50 (maximum). Actual result may vary slightly but that’s okay. So, that’s it!

If not yet contented and would like to make some more effects, then we proceed to the following:

Filters>Distorts>Lens Distortion…This one is fun because you can experiment by adjusting the ‘slider’ left and right, and you can see right away from the Preview screen the result. With this, you can decide for yourself when to stop if already satisfied with the result. You can save as many variants as you like. Quick hint: try to adjust the Brightness, Zoom, and X/Y coordinates. It’s cool! You can come up something like this variant…

So, how’d you like it? Please comment…
