Minolta DiMAGE F100 Review
JPEG/TIFF Image Size & Quality
Standard Test Scene |
The DiMAGE F100 offers a good range of resolution and image
format options. You can choose from JPEG (three compression levels) or
TIFF. In combination with a resolution of 2272 x 1704 (native CCD), 1600
x 1200, 1280 x 960 or 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 ("Super Fine")
- 2272 x 1704 JPEG FINE
- 2272 x 1704 JPEG STANDARD
- 2272 x 1704 JPEG ECONOMY
- 1600 x 1200 JPEG FINE
- 1280 x 960 JPEG FINE
- 640 x 480 JPEG FINE
Images below are cropped 240 x 100 area of the image magnified
200% (nearest neighbour).

In these samples it's difficult to see a big difference
between TIFF and JPEG FINE, for a camera like this it's pretty unlikely
that anyone will actually use the TIFF option (that said if it weren't
there we'd see plenty of complaining...) Dropping down to JPEG STANDARD
does introduce some JPEG artifacts although I think you would be hard
pressed to see them in a print.
Digital Effects Control (Image Processing)
The DiMAGE F100 provides control over four different parameters of its
image processing engine. The first, color mode controls the type of colour
output: normal, vivid, B&W. More familiar are Sharpness, Contrast
and Saturation each of which can be programmed to either less (-), Normal
(0) or More (+). Kudos to Minolta for providing control over these parameters,
however I would like to have seen a wider range of adjustment on each,
the current +/- don't have enough effect to be very useful.
