What does this number next to the number of pictures taken in the lower right corner of Canon 6D display mean?

In the lower right corner of the display screen of Canon 6D camera, the number next to the number of shots indicates the number of photos that can still be stored in the memory card. This number is often referred to as "remaining shooting amount", indicating how many photos can be taken under the current storage card capacity and photo quality conditions.

The remaining shooting amount is a very useful indicator, which can help photographers to know the remaining capacity of the memory card when shooting and avoid the insufficient capacity of the memory card from affecting shooting. It should be noted that the remaining shooting amount is calculated according to the current memory card capacity, photo quality and shooting mode, so the number will change accordingly when changing the memory card or adjusting the photo quality or shooting mode.
