JPEG/TIFF/RAW Image Size & Quality


Standard Test Scene

The Coolpix 4500 offers a wide variety of resolution and image format options. You can choose from JPEG (three compression levels) or TIFF at 2272 x 1704 (full native resolution). JPEG image sizes are 2272 x 1704, 2272 x 1520 (3:2 aspect ratio), 1600 x 1200, 1280 x 960, 1024 x 768 and 640 x 480.

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

  • 2272 x 1704 TIFF
  • 2272 x 1704 JPEG Fine
  • 2272 x 1704 JPEG Normal
  • 2272 x 1704 JPEG Basic
  • 1600 x 1200 JPEG Fine
  • 1280 x 960 JPEG Fine
  • 1024 x 768 JPEG Fine
  • 640 x 480 JPEG Fine

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

The majority of purposes there is very little visible difference between JPEG Fine and TIFF mode. I don't expect many 4500 owners to be using TIFF, but if it weren't there we'd certainly see a lot of people asking for it! After that there is a slight degradation in quality using the Normal setting and a very visible degradation at Basic. The lower image sizes will of course have that crisp sharp look although I was a little disappointed that 640 x 480 JPEG Fine had as many visible JPEG artifacts as it does.
