As photographers we can easily fall into the deep well of creative pursuits and forget about the practical side to creating images. While the rights to your image are set the moment you press the shutter release, proving that is another matter. And that is where the value of registering your copyright becomes important. Most, if not all, countries have some sort of creative protections in place. I will look at this from the U.S. perspective so please investigate your country's copyright laws and procedures if you are not in the U.S..

API Versioning

API versioning is something a lot of API designers don't worry about until the second version of their API. API versioning, however, is a controversial subject with strong opinions on both version representation and behavior.
Adjustment brushes are a really nice feature in Lightroom. Since they made their appearance localized adjustments became easy within Lightroom and I have found less of a reason to roundtrip images to Photoshop for these kinds of edits. A few months ago we took an in-depth look at the adjustment brush, Adjustment Brush Basics - Part 1 and Adjustment Brush Basics - Part 2. If you are unfamiliar with this tool that would be a good place to start.
Recent research suggests that the XMRV assay methods are not reliable
This is a topic that has been covered more than once on quite a few sites. However, it never hurts to review some fundamentals in Lightroom since there are new users everyday! I received two emails last week with virtually the same question about Develop presets. Both readers were having issues when creating and applying their presets since the application of the second (or third or fourth) preset would alter a setting they did not want to alter. One reader's conclusion was that Lightroom's presets were not stackable. This, of course, is not at all true. Once you understand how presets work and how to create them properly, you can stack presets on top of one another and only change the parameters you intend to change.
Every camera manufacturer has its own way of storing the raw data that comes from the sensor. Several manufacturers even develop different formats for different cameras (or create a new format and abandon an older one). It sometimes seems that each new model introduces some wrinkle into the manufacturer's raw format. We see the effect of this in a lag between the release of a new camera and Lightroom's ability to interpret and render images from these new raw formats. While Adobe is rather good at deciphering new raw formats and providing support in a timely manner, they saw room for a new and open standard to store raw data. Enter the DNG, or Digital Negative, raw format.
