I took my new D600 out and shot two soccer games taking 1002 raw images on a 32gig card that said I originally had about 570 shots of memory. It still showed 21 shots left. I asked a fellow photographer about getting some many more shot than I was supposed to, and he said I must be shooting "Raw - Compressed"? So I'm wondering what most people shoot. I've never really paid any mind to it before. Should I now? I appreciate your help, Charles
As Pete describes, the counter is quite conservative. The amount an image can be compressed depends quite a bit on the image. An image with a lot of detail and a lot of different colors results in a large file even after compression. Since the camera does not know what you are going to photograph, it takes the conservative approach. In practice, 14 bit compressed files range from around 20 MB to 30 MB, so your experience is in the normal range.
If you want a smaller file, 12 bit does work. It's a good bit less forgiving of heavy cropping or recovery of shadows, so is more like a JPEG with a little greater ability for post processing.
I am reading Thom Hogan's D600 Guide and his recommendations are paraphrased as follows: Shoot Raw in 14-bit Lossless Compressed for more shadow detail and for an overall quality in the photo; Save SD card space by changing to 12-Bit Lossless Compressed and then changing to 12-Bit Compressed as required.
I've been shooting in 14-bit Lossless Compressed and, as already mentioned, the SD "shot remaining" space is a conservative estimate by Nikon.

The earlier commentary on how the camera calculates space pretty much cover it. Here's another aspect, at least to my way of looking at it.
I have mine set to 14 bit lossless and just finished installing a new RAID 1 NAS box on my computer - let's face it - 24 megapixels needs a lot of room!
For me personally, I want the most color depth and dynamic range and it is my view I will maximize the data available to process in LR4.3 by shooting the camera this way.
I can say I have found the D600 is hard to blow highlights or shadows - I mean really hard. I have not tried 12bit for any length of time or lossy compression, but I know from the past that Nikon does discard some highlight data in the lossy compression.
Just a perspective,
