Best Canon Rebel T8i Settings for Beginners: Change These First

The best Canon Rebel T8i settings for a beginner are a short list: pick the menu style that fits you, save RAW plus JPEG, stop the camera from shooting without a card, and learn one shooting mode beyond auto. Then choose a focus area that matches what you shoot, and you will start getting sharper, brighter photos on purpose instead of by luck.

Meet your camera in one table

The Rebel T8i is sold as the EOS 850D outside North America. It is a DSLR with an APS-C sensor, so any lens you mount shows a field of view reduced by 1.6 times. Canon has since replaced it with the Canon EOS R50, according to The-Digital-Picture. Here are the numbers that matter when you set it up.

Feature	Canon EOS Rebel T8i	Source
Sensor	24.1MP APS-C
Photo size	6000 x 4000 pixels, JPEG, RAW or both
Burst speed	7fps viewfinder, 7.5fps live view
Autofocus points	45 cross-type (viewfinder), 143 with eye AF (live view)
Viewfinder coverage	95% of the frame
Screen	3.0in vari-angle touchscreen
Battery rating	About 800 shots viewfinder, 300 live view
Memory card	SD/SDHC/SDXC UHS-I
Weight	515g

Step 1: Choose Guided or Standard menus

Out of the box, the T8i uses a Guided menu that explains features in plain words, such as how aperture priority can blur a background or keep a whole landscape in focus. Tom's Guide found these walk-through screens helpful for anyone who would rather not read a manual.

The-Digital-Picture's setup guide switches the Shooting screen and Menu display to Standard and turns off the Mode guide and Feature guide, while noting that the Guided versions are useful for beginners. All four sit under Display level settings, Tab 1. TechRadar suggests moving to the Standard display after you have used the camera for a while, so you can reach settings faster.

Think of Guided mode like training wheels on a bike. Keep it on for your first few weeks. When you find yourself skipping past the explanations, switch to Standard. Nothing breaks, and you can always switch back.

Step 2: Set image quality to RAW plus JPEG

A JPEG is like a baked cake: ready to eat, but hard to change. A RAW file is like the ingredients: you need to do a little work, but you can fix much more. The T8i can save either one, or both at the same time.

The-Digital-Picture sets RAW only, with JPEG turned off, because RAW files give the highest quality and are especially valuable for editing. The setting is on Shooting settings, Tab 1, where the top dial sets the RAW choice and the cross keys set the JPEG choice.

For a beginner, RAW plus JPEG is a kind middle ground. You get a JPEG to text to a friend tonight, and a RAW file in your back pocket if a photo comes out too dark or too bright. A mistake in a RAW file is often something you can rescue later, so treat it as a safety net while you learn.

The camera records to SD, SDHC or SDXC UHS-I cards. The-Digital-Picture advises buying plenty of capacity and more than one card, and rotating them so you always keep a backup set until your photos are safely stored elsewhere.

Step 3: Turn on the two safety settings

Release shutter without card: Disable

The-Digital-Picture sets this to Disable on Shooting settings, Tab 1, and warns that leaving it enabled 'will burn you someday'. When it is on, the camera clicks and shows you a picture even with no card inside, and that picture is never saved. Turning it off means the camera tells you right away when the card is missing.

Image review: 4 seconds

The same guide sets Image review to 4 seconds, or sometimes off to shoot faster in the field. Four seconds gives you time to glance at the screen and check that your subject is sharp. If you start shooting fast action, you can turn it off later.

Step 4: Leave auto mode with the mode dial

Digital Trends liked the T8i's large, simple mode dial. The T8i also has auto scene modes for newcomers alongside advanced controls, so you can move at your own pace. Before you turn the dial, it helps to know the three settings that decide how bright your photo is.

The three settings, in plain words

• Aperture is like the pupil of your eye. A wide pupil lets in lots of light. It is written as a number like f/1.8 or f/8, and a smaller number means a wider opening.
• Shutter speed is like a door opening and closing. A quick door (1/500 second) freezes a running dog. A slow door (1/30 second) lets in more light but can blur anything that moves, including your hands.
• ISO is like turning up the volume. It brightens a dark scene, but turn it up too far and the picture gets rough, the way music crackles when it is too loud.

These three work together like syllables in a line of poetry. Change one, and the others need to shift to keep the rhythm, which here means the brightness, the same.

Ken Rockwell's sample photos from the T8i show how this plays out: a hand-held shot of desert palms at f/5, 1/320 second and Auto ISO 200, and a shot of palms in pitch dark at f/1.4, 1/40 second and Auto ISO 25,600. Same camera, very different light, and all three settings moved to match.

Start with aperture priority

In aperture priority, you pick the aperture and the camera picks the shutter speed. The T8i's Guided menu explains that this mode can blur a background behind your subject or keep a whole landscape in focus. Cameralabs suggests a lens like the EF 50mm f1.8 STM for portraits with shallow depth of field, which is that soft, blurry background.

Try this: photograph a friend at the widest aperture your lens allows, then at f/8. Compare the backgrounds. That one experiment teaches more than a page of reading.

Try shutter priority for motion

In shutter priority, you pick the shutter speed and the camera picks the aperture. Use it when something moves: kids, pets, cyclists. Pick a fast speed, take a test shot, and zoom in on the screen. If there is still blur, go faster.

Graduate to manual with the rear dial

The T8i adds a control dial around the four-way buttons on the back, so you can change the aperture directly in manual mode without holding a second button. The same dial handles exposure compensation, which is why the T7i's separate exposure compensation button is gone. Ken Rockwell, for example, dialed in -0.7 stops of exposure compensation for a sunset photo of palms.

Step 5: Understand Auto ISO on the T8i

The ISO button sits on top, right next to your index finger, along with the autofocus mode button, a placement Digital Trends called great. Auto ISO is a friendly place to start, because the camera turns the volume up only when it needs to.

There is one catch. Ken Rockwell notes that Auto ISO on the T8i does not let you pick the slowest shutter speed; the camera chooses it, from a minimum of 1/60 second at normal and wide settings to about 1/(double the focal length) at longer zoom settings. If your photos of moving subjects come out blurry in dim light, switch to shutter priority and choose a faster speed yourself.

The-Digital-Picture turns on ISO expansion under Custom Functions so the camera can reach ISO 51200. You can leave that alone until you need it. Very high ISO is a tool for when the light is almost gone.

Like all Canon DSLRs so far, the T8i has no stabilization built into the body.

Step 6: Pick focus settings that stop blurry photos

The-Digital-Picture puts it simply: a photo must be properly focused for the camera and lens to show their full quality. Choosing the right focus area is often the fastest fix for soft pictures.

Viewfinder focus area modes

AF area mode	What it does	Good for
Single-point AF	You choose one of the 45 points	Still subjects, portraits
Zone AF	One of 9 zones, each made of 9 points	Subjects that drift a little
Large Zone AF	Left, center or right zone of 15 points	Moving subjects in one part of the frame
Auto AF point selection	All 45 points active, closest subject gets priority	Everyday snapshots, people

Canon says the T8i's Intelligent Tracking (iTR) autofocus makes automatic face tracking through the optical viewfinder possible. Digital Camera World found it did a decent job finding faces through the viewfinder in the Auto Selection setting. Start with Auto for people. When the camera focuses on the wrong thing, switch to Single-point and put the point right on your subject's eye.

Viewfinder or live view

When you compose on the rear screen instead, the T8i uses a 143-point area that covers more of the frame, with eye AF added. Cameralabs found this live view face and eye detection confident, and notes it is not available when you use the viewfinder. TechRadar describes the Dual Pixel AF behind it as rapid and reliable.

The tradeoff is battery. Cameralabs lists about 800 shots per charge with the viewfinder and about 300 in live view. Digital Trends also points out that the difference in how a DSLR behaves through the viewfinder versus live view can frustrate new photographers. A simple rule: use the screen for slow, careful portraits, and the viewfinder for walking around all day.

Back-button focus with AF ON

The T8i has a dedicated AF ON button on the back that can be used for back-button autofocus, leaving a half-press of the shutter button just for metering. Digital Trends calls it a technique preferred by many enthusiasts and pros. You do not need it on day one. Once half-pressing feels natural, give it a try: focus with your thumb, then take as many shots as you like without the camera refocusing.

Burst shooting for action

The T8i shoots at 7fps through the viewfinder. In The-Digital-Picture's buffer test, using a fast card and settings chosen for the smallest files, the camera captured 139 images in a single burst before pausing. For a birthday party or a soccer game, burst mode raises your chances of catching the one frame where everyone's eyes are open.

Step 7: Picture Style and noise reduction

The-Digital-Picture sets Picture Style to Neutral with Strength at 1, because the low-contrast Neutral style gives a histogram on the camera that most accurately shows lost highlights and shadows, then changes to Standard in editing software later. That makes the most sense if you shoot RAW and edit. If you mostly share JPEGs straight from the camera, a punchier style like Standard will look better right away.

The same guide sets High ISO speed noise reduction to Off or Low on Shooting settings, Tab 4, explaining that noise reduction destroys image detail and is better added sparingly during editing. If you shoot JPEG only and do not edit yet, you can leave this for later.

A starter setup you can copy

Setting	Beginner choice	Where it is
Shooting screen and menu	Guided at first, Standard later	Display level settings, Tab 1
Image quality	RAW plus JPEG (RAW only if you edit everything)	Shooting settings, Tab 1
Release shutter without card	Disable	Shooting settings, Tab 1
Image review	4 sec.	Shooting settings, Tab 1
Shooting mode	Aperture priority	Mode dial
ISO	Auto, watching the shutter speed in dim light	ISO button on top
AF area	Auto for people, Single-point for still subjects	Viewfinder AF settings
Picture Style	Standard for JPEG sharing, Neutral if you edit RAW	Shooting settings, Tab 3

Where to go next

Change one thing at a time and take a few test shots after each change. If a photo goes wrong, look at the settings it was taken with and ask which of the three, aperture, shutter or ISO, needs to move. Every miss teaches you something you will use on the next shot.
