Kuuvik Capture 4.2 Released

Version 4.2 of my premium Canon tethering app, Kuuvik Capture, is now available on the Mac App Store.

The headline feature is that the app is localized to French. Localization is much more than simple translation, and Agnes did a great job here: the app has a slightly different personality than the English version, but I quite like it. Click the image below for a larger view.

Although I don’t speak French, after spending weeks with the development and my cameras switched to French, I’ve learned quite a lot. It was an exciting and fun experience, I hope you’ll like the outcome!

It was also a good opportunity to revise a few messages (mostly error messages that you seldom encounter). The most prominent change is that the former “manual” white balance mode(s) are now named “custom” to be in sync with contemporary camera menus.

The other new feature is the C-Log mode indicator.

Once a camera is switched to C-Log recording mode, picture styles get disabled. So we reused the picture style selector control to display the C-Log mode and bit depth (on the EOS R, for example, where you can choose to use 8bit or 10bit recording).

Note that in 10bit mode the EOS R can’t record to a memory card (only to an external recorder), so just like the record button on the camera, the record button in Kuuvik Capture will have no effect.

The update is free for existing Kuuvik Capture users. New users can purchase it in the Mac App Store.

My eBook, Kuuvik Capture Inside Out, has also been updated to cover the new version. It is available as a free download from the Kuuvik Capture web site.

Kuuvik Capture 4 : Self-Timer(s)

Kuuvik Capture 4 supports two methods to achieve the self-timer functionality: one built right into the app, and another via the camera.

The app’s implementation is accessible through the intervalometer. In version 4 we’ve lowered the minimum for the Number of Shots field to 1 (it was 2 in previous versions). In this case Trigger Interval is ignored, and the app waits the time specified in Beginning Delay before capturing an image. It also works for brackets, and mirror-lock up (even in auto-release mode) just like the normal intervalometer functionality. Since this is an exposure sequence, you have to use the Run Sequence button (Cmd+R) instead of Capture. This is the method we recommend to use.

There’s one situation, however, in which the camera’s 2s and 10s self-timer drive modes come into play. In a rather awkward fashion, the RC-1/5/6 infrared remote control works only with self-timer drive modes. Kuuvik Capture manages the camera’s drive mode to avoid potential issues caused by some of those (for example continuous drive), and switches back to single frame capture when the camera is in an incompatible drive mode. Now the app accepts both the 2s and 10s self-timer as compatible, so you can use the IR remote to trigger the camera.

You need to set the self-timer/remote control drive mode directly on the camera. While mirror lock-up set in the app will work, auto-release will not.

Kuuvik Capture 4.0 is available on the Mac App Store. It is a free update for users who purchased the app earlier from there. You can see the complete list of new features and changes in the release notes.

Kuuvik Capture 4 : Image Display Enhancements

Kuuvik Capture 4.0 is now available on the Mac App Store. This is the first release in the version 4 series, and brings the first batch of enhancements to the app. The first batch, because instead of waiting for every single feature we planned for version 4 to be complete (and delaying the release significantly), we decided make new features available as they are ready, so you can enjoy their benefits as soon as possible.

Let’s begin discussing the new stuff with the display engine. My FastPath imaging engine, that provides highly optimized image decoding and display, debuted in Technical Camera. Later on the Mark II Artist’s Viewfinder received it. And now Kuuvik Capture joins the club. It provides up to 2x faster JPG display (including the JPG previews embedded into RAW files), plus massive memory savings: I had measured around 100 megabytes less GPU memory usage with 5DS R files, for example.

But the story doesn’t end here. In contrast to this lightning fast preview display, it seemed that RAW loading and decoding (that’s a prerequisite for the RAW histogram and RAW-based clipping warnings) takes forever. And we wanted that users could begin working on the images the instant they appear on the screen. So we made RAW data loading asynchronous, taking place in the background. There’s no more waiting for the “Loading” progress bar.

A circular progress indicator on the RAW histogram’s panel lets you know how the loading goes forward. With the exception of a few operations (such as image deletion and purging) you are allowed to do anything during RAW loading. If you move to another image or capture a new one, loading is automatically cancelled, so you don’t have to waste your time on waiting for something that will be instantly thrown away.

And there’s even more. RAW loading consumes a lot of energy, and there are situations when conserving battery is of paramount importance. Thus we added a new preference to be able to turn off automatic loading completely.

The default is to automatically load RAW data, so that both the RAW histogram and clipping warnings could work as expected. Well, there’s a little difference from previous versions: with the Prefer RAW clipping warning option you’ll see the processed warning layers until the ones generated from RAW data arrive. In previous versions these processed clipping warning layers were not displayed at all.

Should you need the histogram or the warning layers later on, you always have the option to load the RAW data manually. Just click the placeholder on the RAW histogram, or choose the Load RAW data command from the menu, or press Cmd+L.

Power efficiency and speed were always cornerstone features of Kuuvik Capture. This new release brings both to a completely new level.

The last on the list of image display enhancements is support for images in color spaces other than sRGB and Adobe RGB. While images produced by Canon cameras are always in one of these two, images from other sources can be in others as well. For example JPG files produced by Technical Camera can be in the Display P3 color space. ProPhoto RGB and Display P3 are supported on macOS 10.11.2 or later, and arbitrary profiles on macOS 10.12 or later.
