Knowledge is power, or so they say. I believe that knowledge is a powerful thing to have at your disposal and that used correctly it will save you time, aggravation and simplify your life.
I frequently shoot photos at our church for special occasions. This was a celebration of Dan Arteburn's 30 years serving on our church staff. 30 years is a long time for anyone to work anywhere and a church is no different. In fact, it may be more challenging than many other jobs, but that is just my opinion.
So, when you have mixed light sources, floods, LED's and daylight coming in from a window, how do you set your white balance and exposure? I've landed on settings that allow me to get near perfect, SOOC. This image is a jpeg straight out of my Fuji X-E2 with zero post processing. By nailing down the degrees Kelvin, and compensating for the severe lighting, it is a pretty nice image just as it is created.
Not only is knowledge power, it will also make you more profitable. By spending less or zero time in front of your computer "fixing" your images, you can spend that time doing something else. Please don't forget that every additional minute you spend is also less profit for you from that job.
It's a message that has been preached for years, get it right in the camera. You'll be happy you did!
