Getting those as second nature

I had a 2nd watch on Zack's tutorial to get those technical knowledge into my subconscious.  While it may already be late, absorption rate is still at maximum.

It's really important to have those knowledge as 2nd nature, as they will play an important role when I turn professional.

I recall how much I relied on PS when I was still in the early stages of my dSLR - the 'resurrected' shutter journey.  No doubt it helps to make photos more impressive, it's not the core skills in photography.  This processed, more known as PP, is now something I'm taking a hard step away from as the technical skills of getting good shots right off the camera is crucial.
