If amateur photographer unable to see a mood - he should sell his photo gear
Thats a harsh statement. I think the OP can see the emotion, but like many he is unable to satisfactorily portray emotion. There are many components that need to be utilized in our magic bag of tricks, deciding on which and how is the hard part. Many amateurs may not have those skills and we should be there to help them learn them. I for one didn't have those skills for a long time, perserverance and many rolls of film later, I think I can get my viewer to feel what I saw. Not everybody is capable of it, but that doesn't mean he or she should give up, just means they are far better in other areas. Not everyone can pull out the emotion in grand scale, that's why there so many different aspects to photography. That is also why this forum exists, to help those seeking.
