This is for the ones who want total control over the photo. You get to control your shutter speed, aperture and ISO. Based on the need, you can tweak whatever settings you need and you have complete set of settings right at your fingertips.
Often, we hear that pros shoot only in manual mode, believe me, its just a fad. Pros know when to shoot in what mode, that’s all. Getting a photo is much important that shooting at manual mode and screwing the photo altogether.
Personally I use manual mode in conditions where either I have control over on my subject, or if my subject is not going change abruptly.
Go out there and explore the other modes as well and let me know, what is your most used mode. Mine is Shutter Priority.
Last time, M was for Macro.
