Photography 101: JPG or RAW

Digital photography provides many choices when it comes to enhancing your unique vision. Everything from cameras, lenses, and post production software play a unique role in producing wonderful images. There is another piece to this puzzle that you need to consider as well. The question of RAW vs. JPG file formats is one that has no right or wrong answer, only what works best for you. Let’s take a look at these two formats and why you may want to use one over the other.

RAW is the native form in which your camera writes files to the memory card. This means Nikon’s RAW files differ from Cannon, Sony, Pentax, and so on. Each camera even puts its own unique file extensions on each photo. However, the differences in RAW files are more complicated than just file extensions and camera brands.

RAW files contain a large amount of information about a photo. This info ranges from the make of camera all the way down to if you fired a flash or not. That information is stored differently in every manufacturer’s RAW file. For example, Nikon may write the info in this order: camera type, iso, shutter, aperture, lens, date, time, and white balance. However, Pentax may write their info as: lens, date, camera, iso, shutter, time, white balance, and aperture. There is no standard for writing info into RAW files.

All of this info brings on a disadvantage when it comes to the ability for the file to be opened by photo viewing/manipulation software. You may have noticed how patches are released for software like Photoshop, Aperture, or Lightroom when new cameras are released. These patches are necessary to read the native files from these new cameras. As you might imagine, this complexity in RAW files can make it a bit difficult to move photos from one piece of software to another at times. This difficulty is often resolved by converting the original photo into another file format such as a DNG, JPG, or TIFF. Read More→
