Have you ever pulled into a portrait session, grabbed your camera, and immediately thought…

“Wait…what camera settings should I actually use?”

Or maybe you’ve Googled, “What ISO should I use?” five minutes before your session started.

Welcome.

We’ve been there.

When we first started photography, camera settings felt like one giant guessing game. We’d change our aperture…then our shutter speed…then our ISO…and somehow our photos still didn’t look right.

Sound familiar?

The good news is this.

Your camera is not broken. You just need a plan.

And that’s exactly what we’re going to give you today.

Before we jump in, though, here’s one important thing to remember.

There isn’t one magic set of camera settings that works for every portrait session. Every location is different. Every lighting situation is different. Even the weather changes what your camera needs.

Instead of memorizing settings, we want to give you a simple starting point. From there, you can make small adjustments depending on the light.

Let’s keep this simple.

Before we touch any settings, let’s talk about manual mode.

If manual mode still feels intimidating, don’t worry.

Most photographers aren’t confused because manual mode is complicated.

They’re confused because no one explained how the three settings work together.

Those three settings are:

• Aperture
• Shutter speed
• ISO

You’ve probably heard people call this the Exposure Triangle.

It sounds fancy.

It’s really not.

Think of these three settings like teammates.

When one changes, another one usually needs to change too.

Once that clicks, manual mode starts making so much more sense.

Let’s break down each one.

The aperture we start with for portrait photography

Aperture is almost always the first setting we choose.

Why?

Because aperture controls two really important things.

First, it controls how much light comes into your camera.

Second, it controls how blurry your background looks.

You know those beautiful portraits where the person is perfectly sharp but the background is creamy and soft?

That’s aperture doing its thing.

For most individual portrait sessions, we usually start somewhere between f/2.0 and f/3.2.

That gives us a nice blurry background while still keeping our subject nice and sharp.

What about families?

This is where a lot of photographers get tripped up.

Many beginners think the lowest f-stop is always the best choice.

Not necessarily.

The more people you add to your photo, the higher your aperture usually needs to be.

Here’s our general starting point:

1 to 2 people: f/2.0 to f/3.2

3 to 5 people: Around f/3.2 or slightly higher

Large families or wedding parties: f/5.0 or higher

Why?

Because if you photograph a large family at f/1.8, someone is probably going to be blurry.

And trust us…

Mom is going to notice. 😅

Next comes shutter speed.

If someone asked us what causes blurry photos most often…

Our answer would be shutter speed.

Not aperture.

Not ISO.

Shutter speed.

Your shutter speed controls how quickly your camera captures the image.

Even when people think they’re standing perfectly still…

They’re not.

Hair moves.

Hands move.

People sway.

Kids? Well…kids definitely move.

That’s why we almost never let our shutter speed drop below 1/150 for portraits.

In fact, if we’re photographing little kids, we’ll usually go even faster.

Kids have absolutely no concern for your camera settings.

They’re just going to keep running.

Here’s another helpful rule of thumb.

Take your lens focal length.

Double it.

That’s a great minimum shutter speed.

For example:

Using a 50mm lens?

Aim for at least 1/100.

Using an 85mm lens?

Aim for at least 1/170.

Personally, though, we still like starting at 1/150 or faster whenever possible.

It gives us a little extra confidence that our photos will stay nice and sharp.

Finally, let’s talk about ISO.

ISO is the setting most photographers worry about.

Honestly?

It doesn’t have to be.

ISO simply controls how bright or dark your photo is.

Our goal is always the same.

Start as low as possible.

For most outdoor portrait sessions, we’ll usually begin somewhere around ISO 100 to ISO 200.

Then we adjust from there if we need more brightness.

Can you raise your ISO?

Absolutely.

Sometimes you have to.

However, the higher your ISO goes, the more grain or digital noise you may start seeing in your images.

That’s why we leave ISO until last.

First, we choose our aperture.

Next, we set our shutter speed.

Then we adjust ISO until our exposure looks right.

Simple.

Here’s how all three settings work together.

This is the part that finally made manual mode click for us.

Let’s say you’ve started with:

• Aperture: f/2.8
• Shutter Speed: 1/200
• ISO: 100

You take your photo…

And it’s too dark.

Now what?

A lot of beginners immediately start changing everything.

Don’t do that.

Instead, make one adjustment at a time.

Maybe you raise your ISO.

Take another photo.

Still too dark?

Raise it a little more.

Maybe you’re already at a high ISO.

Now you can decide whether opening your aperture a little more makes sense.

Or maybe slowing your shutter speed slightly is the better option.

The point is this:

Don’t panic and change all three settings at once.

One change.

Test it.

Repeat.

That’s how you learn.

Final Thoughts

If camera settings have felt overwhelming, we hope this helped simplify things.

Remember…

You don’t need fifty different settings for every situation.

You just need a simple place to start.

Then, as the light changes, you make small adjustments with confidence.

Because that’s what experienced photographers do.

Not because they’ve memorized every number.

But because they understand how everything works together.

You’ve got this.

And you’re probably a whole lot closer than you think.
