Cine Meter II

Bugs fixed: • In floating-shutter, floating-ISO, and floating-ND modes, over- and underexposure warnings would stick improperly once they were set. No more: once the light level is back in range, the warnings now turn off, as they should. • In floating-shutter, floating-ISO, and floating-ND modes, over- and underexposure would show a + or - on aperture as well as on the floating value. Now the + or - only appears on the floating value, as it should.

• Improved default color calibration settings. • Updated help to include color calibration using recent, high-CRI LED sources. Note: one review says this update is “broken” but it’s working for other people. I've installed from the App Store on 9 different iDevices running iOS 6 – iOS 10 and it's running properly on all of them, and hundreds of new sales and countless upgrades have worked without issues. If you have ANY questions, concerns, or problems—before or after purchasing/updating—please contact me directly: [email protected]

• A minor change to the screen-drawing code, so the screen shouldn't scramble if you hold an iPhone X upside-down. -------------------- If you find Cine Meter II useful, please give it a good review on the App Store. Good reviews encourage further development!

• DIFFERENCE MEASUREMENT: When exposure is locked, you can see how the current exposure and color differ from your locked values. • LOG RECORDING: You can record exposure and color data in log files for analysis in other apps. • SLOWER SHUTTERS: shutters down to 60 seconds for long-exposure work.

• Bug fix: Cine Meter II no longer claims to open text files, so it won't be called when you try to view text files in iOS 11’s Files app (sorry about that!).

• Improved error handling when no mail account is found for sending feedback.

• Low Light Mode switch in Settings, to extend low-light sensitivity by 2.5 to 3 stops. Low light mode lets the camera's shutter speed drop to 1/3 or 1/2 second for better light gathering. In low light mode, images may be blurrier in dark scenes, and the meter may respond more slowly in bright scenes.

Cine Meter II Version 1.8 adds two features: • Photometry: reflected light luminance can be measured in foot-Lamberts or cd/m² (Settings > Show Luminance). • Color Correction panel (iOS 8+ only): tap ⇆ to toggle between ambient-to-target and source-to-ambient corrections.

“Use Computed Brightness” setting added for proper exposure readings on iOS 9. See http://www.adamwilt.com/cinemeterii/computedbrightness.html for details

• Fixed: EV now displays correctly when aperture is 64+ or 0.7-. • Fixed: Low Light Mode now works on older iPads. • Cine Meter II is now a universal app, running natively on iPads as well as iPhones and iPods touch (iPod touches?). • Brightness Correction adjustment added for devices that read 2/3 stop too high in bright light (see “Adjust Brightness Correction” in Help).

• Disable all unwanted “sensors”, leaving only those you normally use (for example: enable Front Luxi and Back Spotmeter, disable all the rest). • Display color tint as Wratten CC number, plusgreen/minusgreen value, or ∆uv. • Save calibration data to a file, so you can delete and reinstall Cine Meter II without losing your calibration. • Haptic feedback on haptics-compatible iDevices. • Fixed a camera lockup bug on older iDevices when closing and reopening Cine Meter II with the Settings screen displayed.

• Fixed the partially hidden landscape mode screenshot title on iPhones. • Design cleanup: the last vestiges of the old iOS 5&6 look and feel have been hunted down and eradicated.

Updated for new iPad mini.

• You can now choose which back camera to use for incident readings, on iDevices with multiple back cameras. • “Luxi” settings now called “Incident Meter” settings, as Luxis are getting very hard to find and most people will use other diffusion.

• You can display color readings as CIE 1931 x,y values: use Help & Settings > Show Chromaticity. • You can fetch brightness and color data remotely using HTTP: use Help & Settings > Enable Web Server.

• Simplified exposure and color meter calibration using only your iDevice’s cameras (details in Help > Quick Start). • Color calibration lets you set both CCT and tint, or x and y if you’re using Show Chromaticity. Tint gain is no longer used. (You can turn on Legacy Color Calibration in Settings to do things the old way.) • “Pure” measurement mode: turn off Show Exposure Controls to declutter the display and focus on brightness and color values.

• Fixed layout bugs when starting with the device face-up or face-down, and on iPads with multiple windows. • Fixed missing status message when the camera isn’t running.

Updated for iOS/iPadOS 26.

• Bug fixed: negative compensation values can now be set again. • Camera indicator’s green glow automatically detected during Front Incident readings. Turn it off in Settings if you don’t want Cine Meter II to warn you about it, or if you use a Luxi™ diffuser.

• Fixed iPhone rotation bugs on some older iOS versions. • Internal changes to reduce Cine Meter II’s risk of technological obsolescence.
