1. Explain the main differences between a raw and jpeg file.
A Joint Photographic Experts Group (JPEG) file is a lossy raster file format that compresses an image to make the file smaller. JPEG files are some of the most popular and widely used image formats in the world. Photographers can shoot in JPEG mode, while graphic designers, illustrators, and other creatives can edit their work in them. A RAW file contains all the uncompressed and unprocessed image data captured by the sensors of a digital camera or scanner. They’re also a type of raster file format, but one that maintains lossless quality. RAW files are not images — they’re just large files filled with the image data as it was captured.
2. Which file is bigger RAW or Jpeg? Generally, a RAW file will be between two and six times larger than a JPEG file. RAW files are bigger because they contain a much greater amount of image data. A JPEG image is essentially all that data compressed down into a smaller file size that’s easier to share.
3. Can you change a Raw file to a Jpeg, once your photos are the computer? How? To convert a RAW file to JPEG in Lightroom, select the RAW file in your Library and go to File Export. In the File Settings, set the Image Format to JPEG and move the quality slider to 100 for the best export quality. Click Export to convert the RAW file to JPEG and save it to your computer.
4. If you were shooting an important event would you shoot it RAW or Jpeg? Explain. The main advantage of shooting in RAW is that you end up with high-quality files to edit into the best possible image. Capturing and storing all the details that pass through your camera’s sensors means RAW files contain a wider dynamic range and far greater color spectrum than JPEGs.
