You can see in these images, some of the colors just blend and others the contrast dictates the artistic expression. It was a great exercise for me to learn about color and how I can use it in food photography. I think the most important aspect of any artistic expression is ‘not to be afraid’. To break the boundaries to create room to think, experiment and grow. It is challenging and exuberating at the same time.
One can also learn from other medium like water color, pastel or oil. I have a couple of boards on Pinterest dedicated to art. Do have a look.
