DNG explained simply
What is “DNG”?
Digital Negative: an Adobe-developed format used to store raw image data and related information.
- 01Original RAW
- 02Supported conversion
- 03Verified archive
How do you use DNG practically?
A small exercise
Convert a copy of a supported RAW file to DNG, then check that your editing software and backup workflow can open it.
- Make a starting version and keep it so you can compare fairly.
- Try the change in the exercise. Keep unrelated choices steady where the exercise allows.
- Compare the result at the size your viewer will actually see. Write down what changed and whether it helped.
How does DNG solve a problem?
It can offer a consistent archive format in a supported workflow.
What can go wrong?
Conversion is not required for every photographer. Keep originals until you have verified metadata and compatibility.
How do you turn the idea into a useful solution?
Start with the specific problem in your image or brief, try the exercise, and keep the version that meets that need. If the result is worse, return to the starting version and change one choice at a time.
Quick check: can you explain the three ideas in the diagram?
Original RAW → Supported conversion → Verified archive. Explain how each relates to the exercise. Then compare the starting version with your result and choose the one that meets your brief.
