All about the composition
With those tips in mind, you can start planning for the layout of your photo. While this versatile style allows for virtually limitless possibilities, it is generally a good idea to pick the colour theme of the composition according to the tone of your subject. By doing so, your photo will attain a unified theme that speaks clearly to your viewers.
Next up, you will need to decide what to include in the picture. While the nature of a flat lay allows multiple items in frame, it is best to include no more than five prominent objects (mood-setting elements like confetti, petals and sprinkles, need not apply), or the audience will be distracted from the intended message. Be mindful of the relationship between the items, and how they come together to communicate the story.
For example, you want to show your passion for pastry making. The pie crust, macarons, cupcake, and sugar cubes are all excellent tidbits of the craft that communicate a mood to your viewers, while their complementary colours make the image all the more pleasing to look at.
