But metadata management is now becoming increasingly popular. Some photographers probably feel comfortable using a folder management system for organizing their photos.

If you do have more than 4 GB of RAM installed, then you should see an 8 percent to 12 percent boost in performance speed. The 64-bit versions of Lightroom allow you to go beyond the 4 GB RAM limit that was imposed on 32-bit operating systems, assuming that you have more than 4 GB of RAM installed on your computer. Intel Mac users will need to follow the instructions in Figure 1.4 to enable the program in 64-bit mode, while Windows Vista and Windows 7 users will need to make sure they download or install the 64-bit version of the program.
