OK, so, I don’t actually believe online petitions have ever fixed anything (I notice Firefly remains canceled, for example), but, gorram it, I found a petition I believe in enough that I signed it anyway, and you should too.
The petition is to the major camera manufacturers to try and convince them to add native support for DNG, the “Digital Negative” format introduced by Adobe in 2004 as an attempt to make a universal, archival format for digital photography.
In a world with a different format basically for every camera, the use of one consolidated Raw format (much as JPEG has become the clear winner in the raster arena) would simplify life greatly for any one using multiple systems (I actually tell Lightroom to import all my photos as DNGs already, I hate being beholden to a different format for every camera.) DNG, being supported by the digital imaging giant that is Adobe, also stands a good chance of surviving as long as digital imaging does (look at how long PSD has been around, for example). And, with Adobe’s editing software by and large the most popular solution for tweaking photos, it smooths things a bit more there as well.
In short, I think DNG is a freaking great idea, and more people need to follow in Pentax’s shoes and add it alongside their proprietary formats (or even replace them with DNG).
