I understand that if I shoot in RAW, post processing software like Lightroom is capable of adjusting colour temperature and tint to my desire.
Will I lose any image quality in process? Or is it as good as shooting with correct Kelvin value?
A common example I've encountered: say I shoot with an old flash gun that doesn't communicate with my DSLR, and it is really up to me to adjust White Balance manually. Am I good if I shoot bunch of unbalanced colour photos (most of the cases, with a blue cast) and fix them through post processing? Or should I spend time getting the colour right (or close) on the spot and be conscious about changing light so I don't need to re-adjust white balance later?
