Browsing by time is a key feature for most photo apps.
- Allow someone to quickly browse over a large time scale (months, years), and identify images or groups of images, as they go
- Adjust to the speed of browsing, and/or the number of photos - slower browsing could reveal more detail, for example
- Group chunks of images
- Make it possible to quickly browse to specific dates (probably months, or years)
- Indicate where in time the current view is
- Indicate number of photos taken at a particular time (helps with the "I know I took a lot of photos around then" case)
Photos for Mac
Shows a zoomed out view for years.
Google Photos Web
A bar is shown on hover, next to the scroll bar. This allows navigating to a date, and ticks indicate activity.
Photos for Android
- Pinch gestures allow zooming in and out
- When scrolling, a floating handle is shown, which allows scrolling more quickly. While dragging the handle, date marks are shown, similarly to Google Photos Web.
