▪ Requires post-processing by special proprietary software
as provided by the camera manufacturer or third-party
software programmers.
▪ Larger file sizes (so you must have large storage media).
▪ No accepted industry-standard RAW format. Each
camera manufacturer has its own proprietary format.
Adobe has a RAW format called DNG (Digital
Negative) that might become an industry standard. We’ll
see!
▪ Industry standard for printing is 8-bit files, not 12-bit or
14-bit files.
Now, let’s examine the most popular format on the planet,
JPEG.
JPEG Image Quality Format
As shown in Figure 3-10, image 2, the D300(S) has three
JPEG modes. Each mode affects the final quality of the
image. Let’s look at each mode in detail:
▪ JPEG fine (Compression approximately 1:4)
▪ JPEG normal (Compression approximately 1:8)
▪ JPEG basic (Compression approximately 1:16)
Each JPEG mode provides a certain level of “lossy” image
compression. The human eye compensates for small color
changes quite well, so the JPEG compression algorithm
