Part 3. More Things You Need to Know about RAW Image Files

1How can I convert raw files to JPEG for free?

You can convert a RAW to a JPG file with a free online photo converter, such as Zamzar. If you have a large number of RAW images to convert, you’d better choose a professional RAW converter to convert RAW files on your Windows or Mac, like WidsMob ImageConvert.

2Does converting RAW to JPEG will lose quality?
Since JPEGs have a narrower range of features than RAW files, the converted JPEG files will be no better than the original RAW files. You may notice significantly reduced quality after converting the RAW images to JPEG format, no matter what features and format were used to record the original RAW data.
3Do professional photographers shoot in RAW or JPEG?
Professional photographers will shoot in RAW more than in JPEG as the RAW format can contain more information on a photo than JPEG and has more space for editing. However, many new photographers will start by shooting JPEGs instead of RAW to get a better sense of their camera.
