I am new to photography. I always ask myself how do people take such good pictures. Q1. I was wondering how do you make a picture pop? I saw a lot of picture, they are so rich with color. How do you do that? My sky is never that blue. Do you use filters etc to make you picture pop or do you use digital software to alter your pictures? Q2. How do you get sharp, rich & vivid picture when taking shooting under the bright sun? I tried polarizer, 0.6 ND & flash fill, doesn't seems to be effective under the mid afternoon sun. Q3. It is a sin to digitally post processed your picture? Thanks.
