The biggest advantage of digital cameras over using film for shooting an eclipse is that you get instant results. With using the Case Air Wireless Tethering System, you can setup your camera, take your shot, and view images on a tablet, laptop, or even smartphone within seconds.

This year there are just two lunar eclipses, the first on February 10-11 and the next rapidly approaching on August 7. It’s impossible to tell how bright or dark the moon is going to be during a lunar eclipse since it varies significantly as the moon moves across the sky, and even can vary from one eclipse to the next. The best advice is to bracket your exposures, shooting as many images as you can by using various exposure settings.

It’s important to remember the eclipse will start with a full, bright moon then dim as the eclipse progresses, then gradually brighten again. By taking lots of pictures at many different settings you increase the chance of getting a great shot.

During the full eclipse, it’s recommended to keep your exposures as short as possible by boosting your ISO to 400 or even higher. This will prevent the image from blurring due to the Earth’s rotation. See www.MrEclipse.com for more information, as well as his informative Lunar Eclipse Exposure Guide.

 

Using the Bracketing Feature with the Case Air

The Case Air Wireless Tethering System comes packed full of advanced features, including bracketing which takes three photos; one using the camera’s settings, one intentionally underexposed, and one intentionally overexposed. The images are then combined in post processing into an image with preferred exposure.

How to Use Bracketing in the App

  • Choose the desired method to change exposure
  • Choose the starting exposure compensation
  • Choose the exposure compensation stepping
  • Select the shutter button to begin taking shots
  • Shots taken and current exposure setting will display at top
  • Once completed, select Quick View to review
  • To clear the Bracketing options, select the Bracketing icon then the Default button
