Basically, Raw is an image format which contains the most of the possible data from your image sensor in the camera. It’s called Raw because it is not processed or edited in any way, and therefore it’s also called “digital negative”. Whereas wide known JPEG file format is “positive” because it’s already processed through Raw converter and it has specific white balance, exposure, contrast and other parameters.
Kalau menggunakan RAW, kita boleh ubah exposure, White Balance tanpa jejaskan kualiti gambar. Cuma leceh je la nak main edit² ni..hehe
