From what I have learnt through research, practice and group discussions is that there are many different factors to taking good photographs of food, here are a few:
Lighting
One of the main factors that kept coming up is lighting, in the photos I have been looking at the lighting has come from the side or from behind the food instead of coming from directly behind the camera.
I have noticed that a lot of websites that give tips on this type of photography say to use natural lighting like this website: http://content.photojojo.com/tips/food-photography-tips/ that says:
“Use natural light whenever you can. The ideal set-up is a next to a large window, with a white curtain to diffuse the light.
If you can’t get natural light, don’t be tempted to use your flash. Flash photography is too harsh for food’s delicate sensibilities. It flattens everything out and makes for unappealing shiny spots.”
Composition/Positioning
I think the next important factor is the positioning of the food and which objects (if any)are included in the photo as well as where the photographer positions his/her camera because this can either make the food look delicious, which is what most people want when advertising, or disgusting.
I figured this out after taking some photos of my own and looking at other people’s work.
Background & Foreground
The background and foreground of the image is just as important as the food you’re photographing, I’ve found a lot of food photos that use plain coloured backgrounds, usually white because this makes the image brighter giving off a fresh feel, other photographers have used darker backgrounds like wooden tables with plates and bowls that match a colour scheme, it all depends on the food you’re photographing.
Depth of field
In food photography it’s best to use a large aperture (shallow depth of field) because this draws the viewer into seeing the details that you want them to see, having the focus in the right place is key to getting across the message that the photographer wants to portray.
Colour
Colours are very important in food photography they contribute a lot to an image working or not, with food I find that turning up the saturation in post production or when shooting makes the food look tastier.
Some other tips I’ve picked up
Be fast but think about what you’re doing, take loads of photos, use different zoom lengths, all of this stuff could make food photos a lot more interesting.
