Alt The Magic Key

August 24, 2012 by A. Cemal Ekin

In the “Lightroom:” series I will try to add frequent short posts about some of the features that may escape attention or a little more explanation of the workings of the myriad of tools. I have an aversion to “tips and tricks” or “quick and dirty tricks” so I am avoiding the terms on purpose. I fully understand the intention in these phrases. However, many, perhaps most, users seem to think that these are the only things to know about software or other technology. I would like to suggest that if you are serious about learning a tool, any tool, you should forget about “quick and dirty” since learning is neither quick nor dirty. Focus on learning, a little at a time, and understand what the tool does and when best to use it. Over time, you will have a nice toolbox where you will learn to reach for the right tools. Learning takes time, accept that and move on, don’t settle for anything less.

Lightroom has become a standard front end in my workflow and I recommend it to other photographers despite certain misgivings I have about the latest version Lightroom 4. Under the “Lightroom” category, you will find other, more detailed and in-depth posts about specific features.

There is one key on the keyboard that has been assigned special duties depending on what adjustment may be in operation. That magic key is the Alt (Option on Mac) key. If you hold the Alt key while using the following adjustments it will help you in the way that is explained next to it. Try it and remember to use it; it is a great help.

Hold the Alt key while using the sliders or making other adjustments as indicated
