If your images are tinted to a warm or a cold haze, it might be because your white balance is of set. To fix this you can use the "Auto White Balance" which 9 times out of 10 should fix the problem. If that does not fix it, you can use the cameras inbuilt presets to sort out the problem. (See Presets Diagram Down Below) - If even that doesn't fix your image, you can try messing around with the manual white balance mode. Kelvins is how colour temperature is measured. A low Kelvin count (Around 1500k - 3000k) will give your image a nice warm feeling. Whereas a Kelvin Count (5500k - 9500k) will give you a much more blue and misty feeling in your images. Horror films for example use high Kelvin Counts, because it gives more of a darker a blue theme.
