Frustrated, she remembered a trick her designer friend once mentioned: “Take the photo on your computer.”

Sarah had spent three hours setting up the perfect flat lay for her small business’s new product launch—hand-painted ceramic coasters. Her phone camera was decent, but the fine cracks in the glaze and the subtle gradients of blue just wouldn’t show up right.

She took twenty shots, tweaked the lighting by simply changing the screen color (white for bright, gray for moody), and instantly reviewed each image on the large display.

Now came the real magic: . She used the computer’s screen to see a live view of the coaster, adjusted the focus with a keyboard shortcut, and triggered the shutter without touching the camera. No shake. Perfect exposure.

Within an hour, she had professional-grade product photos. The next day, her coasters sold out.

Then she realized the real trick wasn’t the webcam.
