If you’ve ever wondered why your pictures never look quite as good as those lavishly spread across the pages of a magazine, part of the answer may lay in the post-processing: photos are very rarely shown straight out of the camera.
Instead, they often go through photo-editing software, which may be thought of as a powerful digital darkroom.
Although Photoshop is the most well-known software, it is also very expensive. This is where Gimp (http://www.gimp.org/) comes in: a free, open-source alternative for your photographic needs. Best of all, you don’t have to be a computer wizard to begin using it – just download , install and run Gimp, open up the picture of your choice and follow these three simple steps:
Add some contrast
What is contrast? Contrast is simply about a difference of tones within the picture. A high contrast will make your darks darker, and your lights lighter – the stronger difference between those extremes, or contrast, will result in a picture that jumps up from the page. But be careful – the higher the contrast, the more fine details you might lose. As in all things, it is a question of balance.
To add some contrast to your picture, simply go to Colors > Brightness-Contrast and move the Contrast slider to the right. Moving the slider will also show you a live preview of the result, so feel free to play around until you like what you see, then click OK!
Warm it up
Every color in the world, and thus in your pictures, is a subtle mix of primary colors: red, green, blue and yellow. Adjusting the level of each of these primaries will change the overall tone of the picture.
First, go to Colors > Color Balance. The window that pops up will offer you a choice of 3 sliders, each playing 2 primary colors against each other: Cyan Vs Red, Magenta Vs Green, Yellow Vs Blue. Moving the sliders will allow you to favor one of these hues over the one opposing it, thus tipping the color balance. Because human beings tend to like warm colors, it is generally a good idea to tip the balance in favor of yellow, and to a lesser extent red. Once again, you will be shown a live preview as you move the sliders, so by all means feel free to experiment – colder or wilder choices may work for some images!
Sharpening, as its name suggests, will make your pictures look crisper – well-defined edges that will make the focus look tack sharp instead of soft or slightly blurred. Although this trick won’t save a bad blurry picture, it will definitely help. And if your picture was sharp to begin with – even better. Sharpening will add a layer of polish that will make the picture look finer and extremely well detailed.
Ready for to work the magic? Simply go to Filters > Enhance > Sharpen. Once again, you will be given a slider to adjust, and a small window containing a 100% live preview. Because sharpening will also aggravate noise and imperfections in an image, do be gentle with it. An amount between 20 and 50 will probably work best – once again, don’t be afraid to experiment!
That’s it – with higher contrast, warmer colors and a pin sharp polish, your picture will now pack a serious punch, achieved in a matter of minutes and a few simple clicks.
