Viewfinder Preview is an iPhone app for previewing camera framing for any combination of camera and lens. Instead of spending all that time setting up your big camera, just choose your desired film/sensor size and focal length in the app and point the iPhone camera at what you want to photo to verify framing. If you are happy with the framing then you can get the big camera out. The app has a large database of camera sensors details and film formats but if the format you desire isn’t there you can add your own custom format. The app is targeted at stills photographers or film makers working in either film or digital. If you don’t have your big camera with you, Viewfinder Preview is still great for photo sketching, location scouting or story boarding. The app includes - Customisable menus so you can include the film/sensor formats and focal lengths you care about. - A fully configurable light meter. - You can take photos with it, so you have a record of shots you were framing. - Photos taken with the app include additional data that describe the film format, focal length and lighting meter settings at the time the shot was taken - Add notes to your photos - A photo gallery for viewing photos taken with the app which also displays the additional data - Share images in emails, messages - Create albums of photos from the same project, trip etc - Create PDF documents of albums - Film stock emulation - Wide angle lens adapter support

Create striking time slice photos directly from your camera. Time Slice Camera helps you capture a scene over time, split it into slices, and stitch everything into one final image. It is made for sunsets, sunrises, changing skies, moving clouds, busy streets, travel shots, creative portraits, and any scene where time and movement can turn a simple photo into something unusual. How it works: - Choose the number of slices - Choose the slice direction - Set the full capture duration - Press start and let the app do the rest The app captures each photo, crops the needed part, and builds the final time slice image for you. Tips for better results: - Use a tripod whenever possible - Use a power bank for longer captures - Tap to focus before or during the capture - Try the front camera for creative portraits - The interface stays fixed, but you can choose the final photo orientation When the capture is finished, your result is saved to your photo library. A sunset is the classic time slice shot, but it is far from the only one. Try it with clouds, storms, city movement, traffic, shadows, waves, crowds, or any scene that changes over time. Share your creations and tag @timeslicecamera or @appwithflow. We would love to see what you make. Need help? Contact us from inside the app.
