Kuuvik Capture 5.3 : JPG Only Download Option

The latest update to my Kuuvik Capture tethering app is now available for both the Mac and iPad.

This is the first Canon remote control solution that offers native Apple Silicon support, and is also optimized for macOS Big Sur.

Regarding new functionality, we’ve added an option to allow downloading just the JPG from a RAW+JPG pair. This ensures a much faster image display in cases where the download is slow – for example when using the camera’s built-in Wi-Fi transmitter.

Download options when shooting RAW+JPG

Of course the camera will store both the RAW and the JPG to the memory card, so you can process RAW files later.

With the release of iPadOS 14.2, Apple fixed the USB tethering bug that rear up its ugly head with iPadOS 14.0. So this very convenient and fast connection option is back in business. But they also took care of another bug report of mine, which makes a pretty neat little feature possible.

iPadOS 13 immediately suspended all USB camera communication when you put the app into the background, for example to write a note, or check a message. With iPadOS 14.2 and Kuuvik Capture 5.3, the connection will stay alive for 30 seconds. Your sequence, or download will continue to run in the background. After 15 seconds you’ll get a notification, that the communication will be suspended soon, but you have plenty of time to return to the app – the easiest way being to tap the notification. This is the same behavior you get when using Wi-Fi/Ethernet connections.

The update is free for existing users. New users can buy the app in the respective App Store. Don’t forget that the Mac and iPad versions are sold together – buy any of them and you’ll get the other for free!

Enjoy!
