RAW vs. JPEG - these are the differences

In this tip we inform you about the differences between RAW and JPEG. RAW is the raw data format that contains untreated and uncompressed image data. JPEG, on the other hand, is a storage format that effectively compresses image data.

RAW and JPEG - the differences

The RAW format takes up more space, but has some advantages over the JPEG format:

• Post-processing: With RAW you have more leeway when editing the images because the raw image data is simply saved. No image data has been lost in this state. However, it is sometimes more difficult to edit the format.
• Quality: In a qualitative comparison with JPEG you can see the difference especially in light and dark areas of the image. Here RAW trumps with finer gradations. This difference can be explained in numbers as follows: JPEG has only 256 brightness gradations per color channel. RAW offers up to 16, 384 levels of brightness.

Disadvantages of RAW compared to JPEG

• File size: The qualitative advantage is of course also a big disadvantage. The storage requirements of RAW files is enormous. You have to expect at least 30 MB per image. On the other hand, you can save good quality JPEG images in 2 to 3 MB.
• Compatibility: JPEG is usually read by any graphics program. For RAW files, on the other hand, a RAW developer like Lightroom or a plugin is required so that programs like IrfanView can read the raw data.
