MRW to PNG for editing old Konica Minolta photos without loss

Photos from a DiMAGE or a Dynax 7D often need some repair work before they are printed again: a stranger in the background of a holiday shot, a lamp post growing out of someone's head, a crooked frame. Doing that work on a PNG keeps every pixel you leave untouched exactly as developed, however many times you save, which is why a lossless copy is the better base for editing than a JPG.

These cameras recorded 3 to 8 megapixels, so PNG copies stay a practical size. Each one is developed with the white balance the camera chose and stored at 8 bits per color channel; keep the MRW too, since it holds more tonal range for any future edit from the RAW.

Once converted, remove an unwanted person or object with AI or make broader edits in the photo editor. For sending finished pictures to family, MRW to JPG produces smaller files.
