Click the camera, not the manual.
The T5i is a small spacecraft with a polite British naming problem: Tv means shutter-priority, Av means aperture-priority, and M means you are now the adult in the room.
Tip: keyboard users can tab to hotspots and press Enter.
Tip: tap a hotspot, then change the mode above.
M mode: three knobs and one meter.
Manual mode is not mystical. It is just this: shutter speed controls time, aperture controls the size of the lens opening, ISO controls amplification, and the meter tells you whether the camera thinks the result is too dark or bright.
Meter: 0 EV, balanced for this simulated scene.
Five-step cockpit flow
Click each step as you practice it on the real camera. The sequence is deliberately mechanical. Muscle memory beats menu archaeology.
Creative Zone, full manual exposure.
ISO 100 outdoors, 400 cloudy shade, 800-3200 indoors.
Faster for motion; slower for more light.
Lower f-number for blur and light; higher f-number for depth.
Needle near 0 is the camera’s “normal.” You can choose brighter or darker on purpose.
Practical first setting: M, ISO 400, 1/125, f/5.6. Point at a normal indoor scene. Then change one thing at a time and watch the meter move.

This simulator is intentionally simple. It teaches the tradeoffs, not sensor physics in a lab coat. The scene changes brightness, noise, motion blur, and background blur as you move the controls.
What changes when you turn the Mode Dial?
This is the map. The row for the selected mode is highlighted.
| Mode | Best use | Main Dial | Av/± button | ISO | Camera still controls |
|---|---|---|---|---|---|
| A+ / Basic | Hand the camera most decisions. Useful when the point is documentation, not craft. | Limited. Often changes scene/quick options only. | Usually unavailable for exposure control. | Mostly Auto. | Exposure, aperture, shutter, ISO, focus choices, flash behavior depending on mode. |
| P | Fast general shooting while keeping creative controls nearby. | Program shift after metering; selected Q value when in Quick Control. | Exposure compensation with Main Dial. | Manual or Auto ISO. | Camera chooses shutter and aperture pair. |
| Tv | Motion control: freeze action or create blur. | Sets shutter speed. | Exposure compensation with Main Dial. | Manual or Auto ISO. | Camera chooses aperture. If aperture blinks, your selected shutter is outside what the lens/light can support. |
| Av | Depth control: blurry background or sharp scene. | Sets aperture. | Exposure compensation with Main Dial. | Manual or Auto ISO. | Camera chooses shutter speed. If shutter blinks, light/lens limits are biting. |
| M | Full control, consistent exposures, flash work, tricky light. | Sets shutter speed. | Hold Av/±, turn Main Dial to set aperture. | Manual ISO or Auto ISO, depending on setup. | Metering guidance and autofocus. You choose the exposure. |
| Movie | Video capture and Live View framing. | Adjusts selected exposure/menu value. Behavior depends on movie exposure settings. | Can participate in manual exposure adjustment where enabled. | Manual/Auto depending on movie exposure setup. | Autofocus mode, movie recording size, exposure automation unless set otherwise. |
| Playback | Review, delete, zoom, protect, inspect histograms. | Moves through images or magnification states depending on screen. | Navigation role, not exposure. | No shooting ISO change. | No capture settings; you are reviewing files. |

In M mode, how do you change aperture?
Which control combo is the usual path?
Small glossary, large payoff.
Stop
A doubling or halving of light. 1/125 to 1/250 is one stop darker. ISO 400 to 800 is one stop brighter.
Shutter speed
How long the sensor sees light. Faster freezes motion but darkens the image. Slower brightens but blurs movement and hand shake.
Aperture
The lens opening. Lower f-number means more light and shallower depth of field. Higher f-number means less light and deeper focus.
ISO
Signal amplification. Higher ISO brightens the file but adds noise and reduces clean detail.
Exposure compensation
In P, Tv, and Av, this tells the camera to make the automatic exposure brighter or darker than its meter’s normal.
AE lock
Freezes the camera’s metered auto exposure so you can recompose without the exposure changing.
AF operation
One-Shot for still subjects, AI Servo for moving subjects, AI Focus lets the camera switch automatically.
Metering
How the camera evaluates brightness: whole scene, center-weighted, partial, or spot. The meter is a recommendation, not a court order.
