Your EOS 7D Mark II has many options that determine the dimensions, image format, quality, and file size. You can choose from two image formats: JPEG and RAW. You have three different sizes for each the RAW image format and five different sizes for the JPEG image format. If you capture images with the JPEG format, you can also specify image quality.
You can capture both formats when you shoot an image, or choose either format. If you’re shooting with two cards in the camera, you have different options.
Your decisions regarding format, image size, and quality determine the crispness of the resulting images, the file size, and the amount of flexibility you have when editing your images. To give you an idea of the difference in file sizes, you’ll end up with a file size of 6.6MB when you capture the largest size image using the JPEG format with Fine quality compared to a file size of approximately 24MB when you capture the same size image using the RAW format.
One of the first decisions you make regarding your images is the file format. You can capture JPEG or RAW images. When you choose the file format, you also specify the image size. If you choose the JPEG format, you specify the quality as well. You even have an option to capture both formats simultaneously, and have other options if you shoot with two cards.
