Make a special effects photo

What can we use instead of colored cellophane, a tripod, or a plain sheet if we can't find them?

For the 'cover flashlights with colored cellophane' step you can use colored plastic wrap, translucent tissue paper, or a piece of colored printer paper taped over the flashlight, replace the tripod by propping your phone on a stack of books or a jar as you 'mount your phone on the tripod,' and swap the plain sheet backdrop for a solid-colored curtain or large poster board hung on the wall.

My photos are coming out blurry or the ghost layer won't line up—what should I try?

If shots are blurry after you 'turn off the room lights' and use colored lights, move the lights closer or increase brightness, stabilize the phone on the tripod or steady surface and use the timer to avoid shake, and for the 'ghost effect' make small pose markers on the floor and nudge the duplicated, lowered-opacity layer in the app until it lines up.

How can I change the activity for different ages so it's safe and fun for everyone?

For younger kids simplify the setup by choosing one easy theme, using just one prop and capturing still photos with adult help for the 'position your props' and 'take a bunch of photos' steps, while older kids can experiment with longer slow-motion video, more props, and advanced blending when they 'add motion,' 'glow,' and 'ghost' effects themselves.

What are some cool ways to extend or personalize the special effects photo after finishing the basic steps?

To enhance the final image, hang lightweight props on fishing line before you 'position your props' to create levitation, combine the motion, glow, and ghost effects into a short looping video in the app, and then export versions to share on DIY.org or print for a themed photo book.
