QTK to JP2 Conversion: FAQ

What are QTK files?

QTK is the proprietary format used by Apple QuickTake cameras for shooting in RAW mode. QuickTake was an innovative digital camera released by Apple in 1994 — it represented one of the first models which could store digital photos and connect to an Apple computer to download them. Nowadays, however, QuickTake cameras are not directly compatible with the Mac OS X platform due to the absence of an old Apple Serial protocol. QTK images can be downloaded using special applications or programs, and converted to more accessible formats.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
