One of the simplest ways to isolate your subject is to remove the clutter from your image. This allows the viewer to know exactly where to focus their attention. You can do this by zooming in or using a tighter crop in post-processing.
Try using this technique today to highlight something that symbolizes strength. As with the prompt photo, by cropping in close the only focus is on the caterpillar. Seeing him hanging precariously on the end of a stalk snacking away shows the strength in those little legs.
With the word strength, you could go literal and show the use of brute strength or figurative with something that helps gives you strength throughout your day.
Can’t wait to see what strength you highlight today!
