I've taken the following shot using my 500D, 18-55 in ION. Time of day: ~8pm
White Balancing - AWB
Metering - Evaluative
EV - 0
This was before alteration
This was after PS. And is closer to what I've actually saw.
In the original image, the tree looks pale as compared to the actual scene. So, the question is as topic, Is this a white balancing or metering issue?
Not sure if the above given information is enough to derive the answer...
