• Croppikerroin?
Cropping factor is to crop the certain area of the sensor, so that camera is able to capture the best quality and sharpest image area of the lenses.
Camera sensor size differ from one camera to another. Various camera has different sensor sizes, the bigger the sensor size the more expensive the equipment is.

• ISO-luku ja sen merkitys kuvaukseen
ISO means the measure of the film sensitivity to light. The lower the ISO, the more of exposure time is required. Lower ISO will produce dimmer images, however it will not have noise like the higher ISO.
• Sulkimen nopeus ja sen merkitys kuvaukseen
Shutter speed or the exposure time is the length of time camera shutter is open. The faster the shutter speed, the image sensor will not be able to capture the light. Therefore the image will be dim and but the picture will be sharp. However when the shutter speed is slow, the sensor will capture unstable images when there is not enough light.
• Valkotasapainon merkitys
White Balance has a huge effects on photography. The Auto White Balance mode will be different from Custom White Balance mood. The eye can differetiate white in various lighting sources, however digital camera image sensor has difficulty understanding white colour from various lighting sources, which will lead the image into blue, orange or greeny. Thefore coffenct white colour balance is needed.

• Syväterävyys valokuvauksessa
Depth of Field is the distance between the nearest object and the furthest object which appear sharp in the images.
The lesser the F number or the wider the aperture, the shallower the image is. Therefore only the nearest focal point will be in focus.
The larger the F number or the smaller the aperture, both the foreground and the background will be in focus.
• Tallennusvälineet
There are varieties of Memory cards, usually they are SDHC and Sony has its own memory card type.

• Optisen ja digitaalisen zoomin ero
Optical Zoom is the real zoom image that you can capture to the sensor, however digital zooming is just the software manipulation to look image larger and the picture quality will drops where the digital zooming is in use.
• Käsitteet tele ja laajakulma
Tele is used for distant zooming, mostly used in Bird Photograpy, Sport events.
Laajakulma is used for landscape, it can also be fish eye, tilt-shift photography.

• Aukon koko ja sen merkitys
Aperture is to control the source of light coming directly to its image capturing sensor. The smaller number of the aperture shutter door will be larger, thus allowing more light fallen onto the image sensor.

Therefore the image will be dim and but the picture will be sharp. However when the shutter speed is slow, the sensor will capture unstable images when there is not enough light.

• Miksi ns. pokkarilla on vaikea saada syväterävyyttä valokuvaan?
In small camera, the image sensor is always smaller than the DSLR. However it is not true that small camera does not produce fine detailed photos, theseday there are mirrorless picture which can produce just like the Mid Rage DSLR.
• Kuinka monta pakkaamatonta kuvaa mahtuu 4GB muistikortille?
10 Megapixel picture will take about 2.5MB and it is differ from camera to camera. It will roughly fit around 1600 pictures.
• Mitä Jpeg pakkauksessa kuville tapahtuu?
JPEG stands for Joint Photographic Expert Groups which created the standard. In JPEG the image captured by sensor are manipulated by software into bytes and then it re compress it back into image. JPEG does always lost the quality of the images, however there is also a looseless JPEG standards but it is not widely used in consumer products so far.
