Digital DoF vs starlogger

Know what will be in focus before you shoot. Digital DoF helps photographers and filmmakers plan depth of field for digital cameras, cinema cameras, and film formats. Choose your camera, enter focal length, aperture, and subject distance, and see your results in a clear, practical layout. PLAN YOUR FOCUS • Calculate depth of field, near and far focus limits, and hyperfocal distance. • See how much of the focus range falls in front of and behind your subject. • Use the visual focus map to understand the calculated range at a glance. • Switch between feet and inches or metres and centimetres. • Adjust circle of confusion when your workflow calls for it.

Starlogger is the session tracker built for astrophotographers. Log every night under the stars — date, site, targets imaged, and exposures per target — paired with the exact camera, mount, optics, and filter wheel you used. Save your imaging sites with GPS coordinates and let Starlogger notify you automatically, even in the background, when you arrive at one. Build reusable equipment kits so you're not re-entering the same rig every session, and browse a growing target catalog as you log. Every session keeps a permanent snapshot of the gear and site you used at the time, so updating your equipment library later never rewrites your history. No sign-in, no cloud account — your data lives on your device and backs up automatically through iCloud Backup. - Session logging with date, site, targets, and per-target exposure details - GPS-based Sites with automatic geofenced arrival notifications - Reusable equipment library: cameras, filter wheels, OTAs/lenses, mounts, and kits - Built-in target catalog - Permanent equipment/site snapshots — past sessions never change when your gear list does - No account required; data backs up automatically via iCloud / Auto Backup for Apps - Miles or kilometers, your choice
