Digital Imaging-Problems And Solutions

Front 1

Flash card failures.

Back 1

Problems
Static charge.
Removing the card while it is reading.
Human error-ie formatting card.

Hint 1

Solutions
Don't take any more photos with the card.
Software can recover the images of they have not been written over.

Front 2

What are artifacts?

Back 2

Undesirable changes to digital images caused by the sensor and internal processing algorithms of the camera.

Front 3

Blooming.

Back 3

Problem.
Overflow of charge from an over saturated pixel to the next sensor.

Hint 3

Solution.
Remedied with a wide angle or digital lens.

Front 4

Dead pixels.

Back 4

Problem.
One or more photodiodes on the sensor are defective.

Hint 4

Solution.
Buy new hardware.

Front 5

Demosaicing artifacts.

Back 5

Problem.
High contrast colors side by side generate a different color at the meeting edge.

Hint 5

Solution.
Requires a higher resolution to render color detail.

Front 6

Moire.

Back 6

Problem.
Occurs when the scene has high frequency detail that is close to or higher than resolution of the camera.

Hint 6

Solution.
Higher resolution.
Move forward or back to adjust the frequency.

Front 7

Posterization.

Back 7

Problem.
Limited dynamic range or too much post processing.

Front 8

What affects the quality of a digital image?

Back 8

Resolution.
Color bit depth.
Lens.
Size of the CCD(Sensor).
File format.
Color interpolation.
Resampling.
Processing of the image.
