Silhouette is a camera app that helps you capture exactly the framing you want. ■ Silhouette Guide Overlay Load a reference photo you like and see it as a translucent layer over the viewfinder. Match the pose and composition as you shoot, and you'll get the same look every time. No reference photo? Pick a built-in pose silhouette (full body or upper body, one or two people). Adjust opacity in five steps, fit by height or width, and flip the guide sideways. Guides appear only on screen and are never saved into your photos. ■ Portrait + Landscape in One Shot One tap of the shutter saves both a portrait and a landscape photo. Choose "4:3+" or "16:9+" in the ratio button to capture the same scene in both orientations at once, so you never have to reshoot for a profile picture and a post. ■ Front + Back Dual Camera Shoot with the front and back cameras at the same time and combine them into a single photo. Swap the main view and the small picture-in-picture view with a single tap to capture yourself and the scenery together. (Available on devices that support simultaneous capture.) ■ Composition Tools · Rule-of-thirds grid · Level indicator: see at a glance when the device is tilted, so your horizons stay straight · Rotate the device and the buttons and frame follow the new orientation ■ Shooting Tools · Self-timer (3, 5, 10 seconds) · Aspect ratios 4:3 / 1:1 / 16:9 · Zoom presets (0.5x, 1x, 2x, 3x) calibrated to your device's lenses · Selfie field of view: Standard or Wide · Flash off / auto / on, with a full-screen flash for selfies · Mirror selfies · Save to your gallery instantly, or review first and then save · Tap the thumbnail next to the shutter to revisit your latest shot · Grid, level, ratio, timer and other settings are remembered next time you open the app Everything is captured and saved on your device. No data is ever sent anywhere.
