JPEG/RAW Image Size & Quality

The HP 850 provides a total of six combinations of image size and quality. There are two selectable image sizes of 2272 x 1704 and 1136 x 848 and three different JPEG compression levels indicated by a number of stars.


Standard Test Scene

To give an impression of what some of the combinations of image size and quality produce the table below is a cross reference of them:

  • 4 MP (2272 x 1704) JPEG
  • 4 MP (2272 x 1704) JPEG
  • 4 MP (2272 x 1704) JPEG
  • 1 MP (1136 x 848) JPEG
  • 1 MP (1136 x 848) JPEG
  • 1 MP (1136 x 848) JPEG

Images below are cropped 240 x 100 area of the image magnified 200% (nearest neighbour).

With the advent of the 850 HP have taken a different approach than they did in the 812, that is they have now split up the selection of image size and quality. With this split we see an increase in the number of selectable JPEG compression levels but not image size, which is a shame. HP do seem to have improved their comression algorithm, very few artifacts at the or quality settings and fairly respectable compression at the setting.
