Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

iMac Pro Updated With 256GB RAM and Radeon Pro Vega 64X Graphics Options
Upgrading to 256GB of 2,666MHz DDR4 ECC memory will set you back a steep $5,200, more than the $4,999 price of the base iMac Pro itself. Radeon Pro Vega 64X graphics can be added for $700. Both are configure-to-order options.
Apple has also lowered the prices of some existing iMac Pro upgrade options. As examples, 64GB of RAM dropped from $800 to $400, 128GB of RAM dropped from $2,400 to $2,000, Radeon Vega Pro 64 graphics dropped from $600 to $550, and 4TB SSD storage dropped from $2,800 to $2,400 in the United States.
A maxed out iMac Pro now runs $15,699.
