I have read some of the comments from the readers and I say that I have to agree with some and disagree with the others. Some would say that a fast prime lens that opens to as wide as f/1.4 would be better than your standard 18-55mm - f/3.5 - f/5.6 lens, however if you know your camera and its settings, then the lens does not really matter.
The article also made mention of the ideal lighting for your food photographs
When positioning food, position it so that the light is illuminating the side facing you from a slight angle. The ideal lighting position for a single source light is to have it just off of one of your shoulders. This means that if taking a shot by window light, the window should be behind you, either off to the right or the left (if it's directly behind you, you end up casting a shadow—no good!). If using a spotlight, the center of the light should hit the table in between you and your food slightly to the left or the right of center so that the food is not illuminated directly from above or from behind.However, the photo of the ice tea above which I took when I went to Mango Tree Bistro was lighted from somewhere behind and above the drink and I would say that the lighting added some more drama to the photograph.
I'm not discounting the other great tips from that particular article. As a food blogger and photographer, I can safely say that when you're starting to photograph food try to learn and follow the rules so that eventually you can learn how to break them and still come up with good photographs whether it's just for your blog or maybe for print.
Learning the basic rules does not mean that you don't let your creativity soar, it doesn't mean that you tie yourself to what you read, what you've been taught. Learning the basics means that you use the things that you have learned as an anchor, a foundation so that you can start being more creative and see the world of food photography with a different set of eyes.
Oh and before I forget, I think one of the tips that was not mentioned on the article was to take into consideration the background of your food. It is not good to have food photos with very cluttered background.
