GIMP is the GNU Image Manipulation Program. It’s a freely distributed software, and is available for Linux, OS X, and Windows. It allows you to do edit images, just as Adobe Photoshop. This time, I wanted to simulate Lomography on a digital photo.
This was the original photo:
1 – First, go to Colors > Curves and set the curves as you like (remember that a good idea can be to increase the main color of the photo, this settings are for increase the red channel, if you need to increase other colors, use different parameters). If you are not comfortable with Curves you can also use Color Balance (Colors > Color Balance) to get a similar result in an easier way.
2 – Then, go to Filters – Enhance – Unsharp mask and set the radius parameters to 5.0, the amount to 0.50 and the threshold to 0.
3 – Open Colors – Brightness-Contrast and set the Contrast to +20 or more, don’t worry if you will get clipped lights and shadows, the result will be more realistic.
Now the photo is quite similar to a Lomo, but we need to add the vignetting to get a perfect Lomography.
4 – Use the Ellipse Select Tool to draw a circle selection.
5 – Feather the selection (Select – Feather) with a large value (about 100 pixels each 1000 pixels of width) and invert the selection (Selection – Invert). 6 – Open Colors – Brightness-Contrast and set -100 for Brightness and +20 for contrast, you can redo this step for harder effect. The result should be similar to the next:
This was the last step of this Lomo photography tutorial for Gimp, next you can see the photo before and after the lomo effect, followed by a collage of real Lomo photos as inspiration.
