Alright well, here's something about shooting food.
Their are many ways to do it.
You could have a studio set-up with some softboxes and monolights, or you could use a Light Tent.
Tents are a great method on taking commercial/tabletop photography, and you can find some great deals on eBay.
One of the most important aspects of food photography is presentation of the food.
From the background, to the actual food itself. It's very important that everything looks good.
In the technical aspect of the photography, you need to light everything well.
So if you need to do food photography, then here is what I recommend.
Try and get a tent, some lamps or if the tent comes with lights than that's great. Familiarize yourself with the food photography that is being taken by commercial photographers. Look at the saturation of the colors in the food. Look at the foods presentation. For example, think to yourself, "Why is that hamburger positioned like that?" etc'...
Examine food photographs and learn the presentation of the food.
Also, in food photography, depth of field is sometimes very important.
You see the main food in focus, and in the back, other foods barely visible and blurred do to your depth of field.
You might not need a tent, as long as you have a solid place to work, and you can compose everything nicely, with good overall lighting.
