PC Magazine has an article entitled Troubleshooting your images and this deals with blurry images, pixelated or grainy images, images too dark or light and poor colour.
Then, Bob Atkins Photography has a new piece about digital image re-sizing:
One aspect of digital images which seems to cause a lot of confusion to beginners is the matter of image size. There are three basic measures of image size:
- Pixel count – e.g 3000×2000 pixels
- Physical size – e.g. 4” x 6”
- Resolution – e.g. 72 pixels per inch (ppi)
The confusion seems to arise because people aren’t sure of how these are related.
Finally, Outback Photo has an article about EXIF metadata:
Whenever you take a picture with a camera, or scan a slide, the firmware of your camera or your scanner captures not just the actual image itself, but also additional data, describing the environment in which the image was taken. This data is called metadata and its understanding and utilization can be an invaluable aid in your workflow.
