To get to be a good food stylist you need to be first a good cook. I am still working to be a good cook. Learning to style your food takes time, practice and lots of food. Paying attention to details is also an important asset for a food stylist.
The more time you spend to make your food attractive, the easier it gets to take the shot. Make more food than a plate so you have material to play with. Before starting to take photos get all the props on the table. Make a selection of pots, plates, cutlery, backgrounds or cloths you want to use in the photo. Maybe you will not use them all, but is good to have them near you. You can also stage some photos without the food.
Your food is the hero in the story. Every props you use need to participate in the story you want to tell. If you want vintage, everything must be vintage. If you want modern, everything goes modern.
In my story, my hero is mushrooms with cheese risotto. I used a brown rustic bowl on a wooden background because I wanted my story to be rustic.
First shot was only with the bowl and the cloth. I put some fresh parsley on top, to complement my dish. I have fresh parsley in the garden. If you by the herbs some hours before, keep them in a jar with water.
From there I build the second shot adding some ingredients from the recipe in the background: cheese and parsley. I used an old pepper grinder in the back and I put the parsley on a piece of wood. The focus is always on the bowl.
Keep taking photos!
