Kuuvik Capture 3.2 : Other New Features

The Dual Histogram and JPG enhancements were discussed in my previous posts, but there are a few other noteworthy additions in Kuuvik Capture 3.2. Let’s see them!

Camera support

First the new cameras. The Canon EOS 6D Mark II and the 200D/Rebel SL2/Kiss X9 are completely supported. Either using USB or via their built-in Wi-Fi. From the older bunch, we’ve added the 1300D/Rebel T6/Kiss X80, as this camera is quite popular among our photomicrography users. We’ve also continued the rollout of multi-point live view and movie recording support. This time adding the 7D, 750D/Rebel T6i/Kiss X8i, 760D/Rebel T6s/8000D and 1200D/Rebel T5/Kiss X70.

Preferred editor

This was also high on the feature request list. The preferred editor is the RAW converter of your choice that you would like to use to quickly open any image from Kuuvik Capture. By pressing Cmd+E (or via the menus, but I bet that the keyboard shortcut will be used more often).

You can designate any app that is registered as an editor for CR2 or JPG files on your Mac as the preferred editor in Preferences.

For me it’s Capture One, but Photoshop is what several people will undoubtedly use. As Lightroom is not registered as an editor, and is unable to open individual files without importing, you will not see it listed. If you use Lightroom, a hot folder should be set up in Lightroom for the Kuuvik Capture session folder, and it will automatically import images from there.

Drag & Drop

This is a huge time saver. I’m opening my previous shoots with Kuuvik Capture a lot, and going through File > Open Session was always a bit tedious. Now you can drag & drop any folder to the app (even to the icon on the Dock) and the app will immediately open it as a session. Simple and effective.

Under the hood

A lot of things are going on under the hood these days. I’ve mentioned updates to the JPG processing engine with huge performance gains in the Dual Histogram post. The Image Browser also got faster, more efficient, and now uses the image’s EXIF date/time when sorting by capture date (instead of the file’s date).

This release sees the first version of our new display engine. It enables the app to work on macOS 10.13 High Sierra, and also works around an acute NVidia display driver problem introduced in macOS 10.12. If you got an empty screen with 5DS/R files on your MacBook Pro you know what I’m talking about. It also paves the way for some pretty neat features coming in the near future.

Availability

Kuuvik Capture 3.2 is available now on the Mac App Store. It is a free update for users who purchased Kuuvik Capture from there. I’m also working on an update to my free eBook, Kuuvik Capture Inside Out, which will be available shortly.

For the complete list of new features and fixes, please refer to the release notes.

Kuuvik Capture 2.4 Released

The latest update to Kuuvik Capture is now available on the Mac App Store. First and foremost, we’ve added support for the brand new Canon EOS-1D X Mark II. This seems to be a great camera with a few quirks – more on the camera itself in a later post. You can connect it to Kuuvik Capture with USB, using the built-in Ethernet connection or via the WFT-E6 or WFT-E8 Wi-Fi transmitters.

We also changed the way shadow and highlight clipping warnings look. In the past we had a hatched pattern that become denser as more channels got outside the exposure range of the camera. The problem was severe moiré and aliasing when you zoomed in and out. Beginning this version the exposure warnings are solid colored, getting more opaque as more channels are affected.

Multi-channel highlight clipping warning

This is an image from last fall, and shows how channels get clipped towards the sun in the frame. First green (the largest patch), then blue and finally red. The more channels are overexposed the less chance to do effective highlight recovery.

Last but not least, I’ve continued the multi-platform code removal process (mentioned in my former post), which brings performance improvements (and battery usage improvements) here and there. For example loading 20 megapixel images from the 7D Mark II got up to 0.1 seconds faster on a 11″ MacBook Air. And overall camera communication is a bit faster and smoother.

The update is free for existing Kuuvik Capture 2 customers. New users can download Kuuvik Capture 2 from the Mac App Store for $79.99 / €79.99 / £59.99.

Kuuvik Capture 2.3 Released

kc2icon@2xVersion 2.3, bringing Canon EOS 80D support to Kuuvik Capture 2 is now available on the Mac App Store.

Since Canon introduced quite a few changes with this body, I had to update both the camera control and the RAW decoder in my Digital Camera Library.

And at this point let me add a few personal comments on the 80D.

While the improved low ISO dynamic range is a welcome addition, this camera is a step back in a few regards. First, it’s not fast enough to support multi-point live view (formerly known as split view). It’s an unfortunate trend with Canon’s newest mid-range cameras: both the 70D and 700D were multi-point live view capable, and none of their replacements/successors are.

Second, the removal of the shutter count feature (it does not affect Kuuvik Capture per se, but indeed affects my ShutterCount app).

Third, Wi-Fi is still on the verge of being unusable. I’ve already mentioned sub-par 70D/6D Wi-Fi transfer speeds in the version 2.2 release announcement post. With the 80D, I was enthusiastic about the Easy Connection option, that is designed to create the camera’s own access point, and to allow using EOS Utility mode with no existing network needed. The idea is something you would expect in 2016, but the implementation is crap. And I’m not talking about the inability to specify a password for this network, but the extremely slow transfer speed. I measured speeds south of 30mps – which is half of the already slow speeds of the mid-range bodies.

Thus, I recommend to stick with using an existing Wi-Fi network and to avoid the Easy Connection option completely. Fortunately using an existing network is not slower than the 70D was (but it’s not faster either).

I took over Kuuvik Capture last year, and decided that I will not release a Windows version. This allowed me to remove former platform independent code and to do Apple-specific optimizations and speed up the app considerably. The code base is large, so this optimization process is still in progress – and this release also includes a few. They are not user visible, but you might notice them here and there. (For the technically inclined – I had eliminated a bunch of memory copy operations between the Digital Camera Library and the user interface.)

On the user-visible changes front, Split View had been renamed to Multi-Point Live View. I think it’s more clear what the feature does this way, plus Apple introduced a completely different Split View into OS X – and wanted to avoid any confusion.

The update is free for existing Kuuvik Capture 2 customers. New users can download Kuuvik Capture 2 from the Mac App Store for $79.99 / €79.99 / £59.99.

Kuuvik Capture 2.2 Released with Wi-Fi Support

The latest update to my Kuuvik Capture camera remote control app went online earlier today. Although it looks like a small update on the surface, there’s a huge change under the hood. This version contains the 3rd generation of my digital camera library – with full Wi-Fi and Ethernet connection support.

You may remember that we had dropped the network camera option during the beta, because Apple’s PTP-IP (the protocol used to talk to the camera over Wi-Fi and Ethernet) implementation turned out to be unreliable under heavy load. Not to mention the side effect that Image Capture started every time we connected a camera.

So I took the challenge and developed a completely new PTP-IP transport component, debuting in Kuuvik Capture 2.2. If you think that it’ll appear in other apps in the future, then you’re on the right track… But let’s concentrate on Kuuvik Capture now.

Connecting your camera via Wi-Fi (or Ethernet)

First of all, you’ll need either a Wi-Fi equipped camera (6D, 70D), a built-in Ethernet socket (1D X, 1D C) or a separate Wireless File Transmitter (5D Mark III, 5DS, 5DS R, 7D Mark II, 1D X, 1D C) for this to work. Only Canon’s transmitters are supported, third party Wi-Fi remote control boxes will not work. Please check the tech specs for the full list of compatible equipment.

Canon cameras provide connectivity in several ways. The most complete is the EOS Utility connection mode. For this mode a camera needs to be paired to a given app on a given computer. Using two apps on the same computer? You need to pair the camera to them separately, and only one can be active at a time.

The computer side of this pairing process is dramatically simplified in Kuuvik Capture 2 compared to both version 1 and Canon’s EOS Utility.

Kuuvik Capture now needs to be “pairing mode” to accept a pairing request coming from the camera. This mode is accessible through a new menu item (or by pressing F2).

networkPairing

Pairing can be initiated from the menu.

Kuuvik Capture displays the pairing window (shown below) while in pairing mode. This window also shows your computer’s name, which will appear on the camera’s LCD during the last pairing step, so you can double-check that you are pairing to the computer you were intended to.

networkPairingWindow

The pairing window. Kuuvik Capture is ready to accept pairing request only when this window is displayed.

And that’s all you need to do on the Mac.

Once in discoverable state, you can start the configuration process on your camera. The process consists of three large steps:

  1. Choose a connection mode.
  2. Configure your network.
  3. Do the actual pairing.

They are documented in your camera’s or wireless transmitter’s user manual, but there are a few important points to consider.

First, please don’t start any Canon app that may be mentioned in the manual. You are now pairing to Kuuvik Capture, and not to Canon’s apps.

For step 1, you must use the Connection Wizard on cameras where it’s available (e.g. 5-series, 7-series with the external brick), otherwise you won’t be able to complete step 3. On the 6D and 70D choose the Remote Control (EOS Utility) mode. On other cameras choose EOS Utility mode in the Connection Wizard.

In step 2, the camera will ask for network specific parameters (whether it’s wired or wireless, plus various options and a password specific to your network). This is the most complicated part of the entire process, but Wi-Fi setup is such a thing… I’d recommend to study the camera/transmitter manual beforehand.

Out in the field with no network to connect to? My previous post shows you how to create a fast and secure Wi-Fi network on your Mac!

The last step is the actual pairing. As the LCD indicates, this is your last chance to put Kuuvik Capture into pairing mode. It may take up to 1.5 minutes for the camera and your Mac to find each other.

camerapairing1

This is how the camera’s LCD will look like as soon as they found each other:

camerapairing2

Pairing should be done once (unless in the meantime you paired your camera to another app, another computer, or used another network). To deal with these different scenarios, the very last screen in the process (after clicking that OK button) lets you save up to 5 (3 for 6D/70D) setups into your camera’s memory. But if nothing has changed, Kuuvik Capture will find your camera automatically the next time you turn it on and connect to the network, so the pairing is not necessary every time you want to use a Wi-Fi or Ethernet connection.

When pairing has successfully completed, the camera’s LCD will turn black, the pairing window will disappear, and the camera’s name will show up in Kuuvik Capture’s camera selector.

Notes on Wi-Fi speed

It seems that Canon implements one of the lowest speed classes for each of their Wi-Fi implementations. This is 150mbps for the external 802.11n bricks (using only one spatial stream), and a shockingly low 60mbps for the 6D and 70D (despite they advertise it as 150). So don’t expect miracles and be prepared for 12-15 second downloads on these slower cameras. On the other hand, the external bricks are fast enough to be perfectly usable when the network signal is good.

Well, speaking of bad, flaky networks. While I absolutely hate to add new configuration options (one more thing for you to deal with), this time it was a must.

Wi-Fi networks can become unbeliveably slow (think longer distances and/or interference), causing the camera to disappear from Kuuvik Capture. A longer network timeout (a longer time allowance for intermittent network errors to clear) may solve this, but at the expense of delaying the detection of actual issues (such as when the battery dies). So the Preferences window now has an option to control this.

ntoPreference

The default is 10 seconds, which we found to be suitable for most Wi-Fi networks. You can go as low as 5 seconds or as high as 30 seconds. My personal preference is to go with the lowest number, and raise it in the presence of connectivity issues.

Other new features

There are two of them. Customers have asked for more, longer time options for mirror lock-up auto-release. So we’ve added 8s, 10s and 15s to the palette. Also the new white priority white balance mode introduced with the 5DS/R is now available on the white balance control.

Availability

The update is free for existing Kuuvik Capture 2 customers. New users can download Kuuvik Capture 2 from the Mac App Store for $79.99 / €79.99 / £59.99.
