Basic Shooting Modes
The Canon Digital Rebel XTi manual details modes like Auto, Program (P), Shutter Priority (Tv), Aperture Priority (Av), and fully Manual (M) for varied control.
Auto Mode for Beginners
The Canon Digital Rebel XTi manual clearly explains Auto mode as the simplest option for new photographers. In this mode, the camera automatically selects all settings – aperture, shutter speed, ISO, and white balance – to achieve what it deems the best exposure.
This is ideal for point-and-shoot simplicity, allowing beginners to focus on composition and capturing the moment without needing to understand complex photographic principles. The manual emphasizes that while convenient, Auto mode offers limited creative control. It’s a great starting point to learn, but exploring other modes unlocks the camera’s full potential.
Program Mode (P) – Semi-Automatic Control
According to the Canon Digital Rebel XTi manual, Program (P) mode offers a balance between automatic convenience and creative control. The camera automatically sets the aperture and shutter speed, but allows the user to adjust ISO, white balance, and Picture Style.
This mode is excellent for situations where you want the camera to handle the technical aspects, but still desire some influence over the final image. The manual highlights Program mode as a stepping stone towards fully manual control, providing a comfortable transition for learning photographers.
Shutter Priority Mode (Tv) – Controlling Motion
The Canon Digital Rebel XTi manual details Shutter Priority (Tv) mode, allowing photographers to dictate the shutter speed while the camera automatically adjusts the aperture for proper exposure. This is ideal for capturing motion – freezing action with fast shutter speeds or blurring movement with slower ones.
The manual emphasizes that understanding shutter speed is crucial for creative control. Experimenting with Tv mode allows users to master motion blur, panning techniques, and capturing sharp images of fast-moving subjects, offering a powerful tool for artistic expression.
Aperture Priority Mode (Av) – Controlling Depth of Field
The Canon Digital Rebel XTi manual explains Aperture Priority (Av) mode, where photographers select the aperture (f-stop) and the camera automatically sets the shutter speed. This mode is key for controlling depth of field – the area in focus within an image.
The manual highlights that wider apertures (lower f-numbers) create shallow depth of field, ideal for portraits, while narrower apertures (higher f-numbers) yield greater depth of field, suitable for landscapes. Mastering Av mode unlocks creative control over focus and background blur.
Manual Mode (M) – Full Control
The Canon Digital Rebel XTi manual details Manual (M) mode, granting photographers complete control over both aperture and shutter speed. This mode requires understanding the relationship between these settings and their impact on exposure.
The manual emphasizes that M mode is ideal for challenging lighting situations or when precise creative control is desired. Photographers can independently adjust aperture for depth of field and shutter speed for motion blur, achieving a specific look. It’s a powerful tool for experienced users.

Focusing and Image Quality
The Canon manual for the Rebel XTi explains autofocus modes, image quality settings like RAW versus JPEG, and ISO adjustments for optimal results.
Autofocus Modes and Selection
Canon’s Digital Rebel XTi manual details various autofocus (AF) modes for diverse shooting scenarios. One-Shot AF is ideal for stationary subjects, locking focus when the shutter button is half-pressed. Continuous AF (AI Servo) tracks moving subjects, continuously adjusting focus.
Manual focus is also available for precise control. The manual explains selecting AF points, crucial for accurate focusing on your desired area within the frame. Understanding these modes, as outlined in the Canon documentation, is key to capturing sharp, well-focused images with your EOS 400D.
Understanding Image Quality Settings (RAW vs. JPEG)
The Canon Digital Rebel XTi manual explains the difference between shooting in RAW and JPEG formats. JPEG files are compressed, resulting in smaller file sizes, ready for immediate use, but with some data loss. RAW files, conversely, contain all image data captured by the sensor.
This allows for greater flexibility during post-processing, enabling adjustments without significant quality degradation. The manual details how to select your preferred format, advising RAW for serious photographers seeking maximum control and JPEG for convenience.
ISO Settings and Noise Reduction
The Canon Digital Rebel XTi manual thoroughly covers ISO settings and their impact on image noise. Higher ISO values increase sensitivity in low light, but introduce more noise – visible graininess. The manual guides users through selecting appropriate ISO levels for various shooting conditions.
It also details the camera’s built-in noise reduction features, explaining how to minimize noise at higher ISOs. Understanding these settings, as outlined in the manual, is crucial for achieving clean, detailed images in challenging lighting scenarios.

Advanced Features and Settings

The manual explains how to customize these styles, adjusting each parameter to achieve a unique look. Users can create and save custom Picture Styles for consistent results. This feature offers creative control without post-processing, streamlining workflow and delivering desired image characteristics straight from the camera.
Metering Modes – Achieving Proper Exposure
The Canon Digital Rebel XTi manual thoroughly explains the camera’s metering modes – Evaluative, Partial, and Center-weighted Average. The manual details how each mode assesses light to determine optimal exposure settings. Evaluative metering is ideal for general scenes, while Partial metering focuses on a small area.
Center-weighted Average prioritizes the center of the frame. Understanding these modes, as outlined in the manual, is crucial for correctly exposing images in various lighting conditions, preventing over or underexposure and ensuring balanced photographs.
