In this paper, we present a novel method to take photos with a hand-held camera. Cameras are being used for new purposes in our daily lives these days, such as to augment human memory or scan visual markers (e.g. QR-codes) and opportunities to take snapshots are increasing. However, taking snapshots with today's hand-held camera is troublesome, because its viewfinder forces the user to see the real space through itself, and it requires complicated operation to control zoom levels and press a shutter-release button at the same time. Therefore, we propose ClippingLight that is a combination method of Projection Viewfinder and tilt-based zoom control. It enables to take snapshots with low effort. We implement this method using a prototype of real-world projection camera. We conducted user study to confirm the effect of CippingLight in situations to take photos one after another. As a result, we found that ClippingLight is more comfortable and requires lower effort than today's typical camera when a user takes a photo quickly.
