Please make sure to follow the basic recommendations hereafter before tethering your camera.
Not all cameras support tethered shooting, and those that do may need to be set up in different ways to enable this functionality. When those settings are modified you must disconnect the camera and then reconnect.
In general it is recomended to update the camera’s firmware to its latest version: usually a firmware update packs more fixes than those mentioned. For Nikon DSLRs you can check this webpage and this one for Canon.
Turn off Camera Detection in every other applications such as Image Capture, Photos (Yosemite and newer), Nikon Transfer, Graphic Converter, or cloud web services such as Dropbox, etc. If you don’t, those applications will launch, sometimes in the background, when you connect a camera. If you have installed Canon applications, then ensure in Image Capture that No application is selected following a camera connection, as the Canon applications have no setting to turn them off; if you don’t those will launch automatically when a camera is connected, hence blocking Solar Eclipse Maestro.
When you connect your DSLR loaded with a memory card full of hundreds of images, the camera may not be identified. If that is the case, then wait until the memory card access light stops flashing.
WiFi on the Canon EOS 6D and 70D should be turned off as it can block the USB port when turned on.
On Panasonic cameras make sure you use the mechanical shutter as exposures over one second do not work with the electronic shutter or else don’t use any exposure over one second. Also do set the exposure mode to Manual 'M' and drive mode to 'Single' as those two settings can not be modified by the application. Please note that the date and time can not unfortunately be synchronized with those cameras, so you’ll have to do it manually.

Please make sure you set and/or check the following items on your camera prior to connecting it:

  • Exposure stop increment to ⅓
  • ISO stop increment to ⅓
  • Manual (M) exposure mode (Bulb (B) and Program (P) can also be used in certain circumstances)
  • Autofocus should be turned off
  • Deactivate any noise reduction (long exposure and/or high ISO)
  • Proper connection mode (refer to table below or consult your camera documentation)
  • Memory card slot 2 recording setting on capable cameras (best performance with "Overflow" for Nikon and "Auto switch card" for Canon)

For optimal speed and highest dynamic range, set the image quality on the camera to 14-bit RAW lossless compressed and 12-bit RAW if the former setting isn’t available. Compressing the image file takes less time than writing the data size difference to the memory card.
