Last week I covered the three things you should do if you buy a DSLR or mirrorless interchangeable lens camera. Second and arguably most important on that list was mastering your camera's "Manual" mode. Here we're going to dive into exactly how that's done.
In "Manual" mode, you take over the decision making for your camera. You ask yourself What am I trying to show in this image? How do I want it to look? How do I gather enough light to get the job done?
The answer to all those questions rests in three settings: shutter speedaperture (aka "f-stop"), and ISO. They all do different, important things, but each impacts how much light your sensor absorbs. If they're out of balance your shot comes out under- or over-exposed. But understand them and you can push your photography to levels impossible in "Automatic" mode.
Here's how they work.
