We're in the grips of the third big snow storm of this winter. About 8 - 10 inches fell overnight and it doesn't show signs of stopping. Here on Long Island's south shore, wind and cold temp off the water are more of an issue than the snow fall, driving is a challenge as we are last on the town's snow-plow route... Clear days are graced with a beautiful view of the Great South Bay. Today, visibility is measured in feet.
My house is full of interesting things to photograph but today I will concentrate on two other activities...
Spring cleaning of my gear closet and making a list of things I can throw in the for-sale forums, and spending some time in Lightroom finishing the keywording of a few recent shoots (until my wife yells at me to get off the computer..).
I've been dedicating a good deal of time to learning the nuances of Lightroom3 Beta..fingers are crossed that the roll-out will be soon as I really like the enhancements. I am reluctant to convert my current LR catalog over to LR3 since it is still Beta. FYI..you can import existing
DNG's image files using the Add command in LR3's import dialog while keeping them in your current LR catalog, and make all the edits and changes you wish without disrupting the original files. LR3 recognizes all the changes, keywords and exif info from the earlier version and also picks up all your presets, keyword lists and print templates, but your changes in LR3 won't be seen in the earlier versions...not backward compatible. So you can can dive into LR3 with a familiar look and feel of your older version. Fun!!

What's a DNG?
ReplyDeleteJack.. good question. DNG is the abbreviation for Adobe's Digital Negative file format. The most common file type for digital images is the JPEG format (named after the Joint Photographic Experts Group who created the standard).
ReplyDeleteJPEG would similar to the final printed images we used to get from the printer when we took our film in for processing. Your ability to make changes to JPEG files after they are created is quite limited...the file data is "baked in".
Most digital camera's have the ability to capture the image data in it's unprocessed format, referred to as the RAW file, which contains all the data the camera's sensor is capable of capturing. This gives you far more headroom for making changes to the file in post production. It is like having the original negative to work from.
DNG is a converted form of the RAW file, created by Adobe, which I find easier to work with than the RAW file once it is in the computer (though keeping the RAW file or converting to DNG is very much a matter of the preference of the photographer and his/her workflow).
To see one reason why I feel RAW and DNG are a better choice than JPEG, go here...
