Normally the camera uses matrix metering, in which it divides a wide area of the frame into multiple segments and sets exposure based on a variety of information, including subject brightness and color. The metering mode determines which areas of the frame are used by the camera to measure subject brightness and how the camera sets exposure. The camera does not simply measure the overall brightness of the frame, but measures brightness separately in multiple areas of the frame.

The camera optimizes exposure by adjusting shutter speed, aperture (f-number), and ISO sensitivity according to the brightness of the subject, which is measured using the camera's built-in metering sensor. Try connecting your camera to a different USB port on your PC.Metering is used to measure the brightness of the subject.

Make sure you have the latest drivers for your USB controller. Using any other cable than the one supplied by Nikon seems to increase the probability of SessionFailure exceptions.ĭo not use any USB hubs/switches. Make sure to use the USB cable that came with your Nikon DSLR. Forgetting to call Shutdown() leaves the 'source' object open and seems to increase the probability of SessionFailures. This is easy to forget during development and debugging. Make sure to call the Shutdown() function on your NikonManager object before terminating your application. There are a few things that seem to influence the frequency of SessionFailure exceptions. They confirmed that SessionFailures are caused by multiple open sessions and that this error state is un-recoverable, meaning that restarting the WIA service is the only way to recover from this. If the client tries to open more source object, theĮdit: Through convoluted ways, I managed to get in contact with the Nikon SDK engineers. The module cannot open source object because the camera cannot open more session.

Reboot your PC (which effectively achieves the same) Restart the 'Windows Image Acquisition (WIA)' service orĢ. All I know is that when it happens the SDK usually becomes useless and the only way to fix it is to:ġ. This is a feature that could possibly make it into the wrapper in the future, but for now no such functionality is supported. You would have design an inter-process communication scheme to transfer data to and from these controller processes. This appears to be a limitation in the Nikon SDK: Each MD3 file can only handle ONE device at the time within the same process.Ī possible workaround for this would be to build a process isolation system, where each camera is controlled from a dedicated process. Unfortunately, connecting two (or more) identical cameras, such as two D7000s does not work. I've successfully controlled a D90, a D5100 and a D7000 simultaneously from a single application. If you plan on connecting multiple different camera models, all of which use different MD3 files, then yes! Can I connect multiple cameras to the same PC? See Does the library work with VB.NET too? I can't find an MD3 file for my (old) camera on Nikon's website - What can I do?

#D60 LIVEVIEW CODE#

The project source code includes a WPF example application that demonstrates this. You typically want to call GetLiveViewImage from a timer, perhaps a DispatcherTimer. If you want to provide a 'live view' viewer in a UI applications, for example. This will return a list of 'capability info' structures that describes the properties of individual capabilities.įileStream _videoFile = null void device_VideoFragmentReady ( NikonDevice sender, NikonVideoFragment fragment ). You can ask the NikonDevice what capabilities it currently supports by calling GetCapabilityInfo. Most features works fine even when a memory card is not available. The solution is to empty your memory card.Īlternatively, you can remove your memory card altogether. The DeviceAdded event will NOT be fired until this internal enumeration process is complete. If you have a large, slow card and a lot of photos this can take a very long time. When you connect your camera to your PC, the Nikon SDK (apparently) have to enumerate all the items on your SD/CF card. (Are you using a D40, D60, D80 or D200? See below) Why does it take so long for my camera to be recognized? Now, copy the MD3 file along with the accompanying NkdPTP.dll to this directory and try again. This will cause the library too look for the MD3 file in the 'current working directory' which is usually the directory where your application executable (.exe) is located. Note: Replace 'Type0003.md3' with the MD3 file that matches your DSLR NikonManager manager = new NikonManager ( 'Type0003.md3' )
