Picture styles can be used to change the appearance of a JPEG image.
This can be useful when looking for a specific style whilst taking images opposed to using photoshop to edit an image.
There are many different picture style e.g -
Standard
Contrast
Sepia
Saturation
Black & White.
Whit balance is changed for the many different environments or lighting you are in whilst taking a picture.
The lower the Kelvin (what white balance is measured in) e.g. 3000 K - 4000 K this should be used for something like a sun rise or sun set, so a light picture, the lower the white balance/Kelvin e.g. 9000 K -10000 K this should be used for something like an overcast, heavy sky picture.
The aim of white balance is to make sure the camera see's the same colour as what we do through our eyes. If the white balance isn't set correctly the camera could produce a picture that is either cool or warm giving it incorrect tones.
Raw Vs JPEG
JPEG -
is a format that is usable with almost any software.It's a compressed file which saves space but lacks quality. It can be manipulated but losses quality each time you save the file.
Raw -
Is a format that can only be used by certain software as it requires a codec. Raw is a format that is uncompressed or processed. It contains all the information from when the picture was taken and allows changes such as picture style and white balance to be made. Raw files are 2 -6 times larger than JPEG.
