Adobes Lightroom software has long been hailed as the go-to program for photographers who need better control over their workflow. The biggest drawback of Lightroom Mobile is that you need to have the latest desktop version of Lightroom 5 (5.4) before it works. This means that those who have an older version of Lightroom will have to shell out $79 to upgrade, while those who dont own a copy need to pay $99 for the program.
