I recently heard about this from my boss and I was surprised when I tried it out. There's this online support program that enhances digital pictures exclusive for food still-life photos.
Foodpic.net utilizes its patented 'AccuSmart' to enhance the color and lighting of your food photos. The way I see it, its almost the same enhancements I use in my photos. Increasing the gamma correction and contrast, fine tuning the color saturation levels, and boosting the hue that makes the photo warm and focused. Its simple to use; just browse for your target photo, click upload and let the website do the rest.
Its a simple way to enhance your photos, making it more appealing...and yummier.
