Nikon Coolpix 2500 Review
JPEG Image Size & Quality
The Coolpix 2500 keeps its overall operation simple (thus no TIFF or RAW modes) but also manages to provide the user with a good selection of image size and quality settings. You can choose from 1600 x 1200, 1280 x 960, 1024 x 768 and 640 x 480 for the image size and Fine, Normal or Basic as JPEG quality settings.
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 some of them:
- 1600 x 1200 Fine
- 1600 x 1200 Normal
- 1600 x 1200 Basic
- 1280 x 960 Fine
- 1024 x 768 Fine
- 640 x 480 Fine
Images below are cropped 240 x 100 area of the image magnified
200% (nearest neighbour).
|1600 x 1200|
|1280 x 960|
|1024 x 768|
|640 x 480|
In the JPEG quality steps between Fine, Normal and Basic show a progressive increase in JPEG artifacts (as we'd expect). Having said that 1600 x 1200 Normal seems to provide the best compromise between quality and storage capacity for users with small to medium storage cards. Other users would be best to stick with 1600 x 1200 Fine.
The Coolpix 2500 provides five different image sharpening settings. Auto (the default) causes the camera to automatically select High, Normal or Low settings depending on the image content. For the best results without sharpening artifacts the Low setting seemed to be the best, although you will have to be prepared to sharpen the image later using something like an Unsharp filter in Photoshop.
