AF Modes (One-Shot, AI Servo, AI Focus)
The Canon Rebel XSi offers three primary autofocus (AF) modes, each suited for different shooting scenarios. One-Shot AF is best for stationary subjects; the camera focuses when you half-press the shutter button and locks focus until you shoot.
AI Servo AF is designed for tracking moving subjects. The camera continuously adjusts focus as long as you hold the shutter button halfway down, following the subject’s motion. AI Focus AF intelligently switches between One-Shot and AI Servo, attempting to determine if the subject is moving. While convenient, it can sometimes be unpredictable. Understanding when to use each mode is crucial for capturing sharp images. Experiment with these settings to master focusing on both still and dynamic subjects, maximizing your XSi’s performance.
Exposure Control: Aperture, Shutter Speed & ISO
Mastering exposure is fundamental to photography, and the Canon Rebel XSi gives you control over three key elements: aperture, shutter speed, and ISO. Aperture controls the lens opening, affecting depth of field (how much of the image is in focus). A wider aperture (lower f-number) creates a shallow depth of field, ideal for portraits.

Shutter speed determines how long the sensor is exposed to light, influencing motion blur. Faster shutter speeds freeze action, while slower speeds can create motion blur. ISO measures the sensor’s sensitivity to light; higher ISOs are useful in low light but can introduce noise. Balancing these three settings allows you to achieve a properly exposed image with the desired creative effect. Experimenting with these controls unlocks your artistic vision.
Image Quality & File Formats (RAW vs. JPEG)
Choosing the right file format significantly impacts your post-processing flexibility. The Canon Rebel XSi offers two primary options: JPEG and RAW. JPEG files are compressed, resulting in smaller file sizes and are ready to share, but lose some image data. They require minimal editing.
RAW files, conversely, contain all the data captured by the sensor, offering maximum editing latitude. This allows for greater control over white balance, exposure, and detail recovery. However, RAW files are larger and require processing in software like Canon’s Digital Photo Professional or Adobe Lightroom. For critical work and extensive editing, RAW is preferred. For quick snapshots and immediate sharing, JPEG is sufficient.
Using Live View & Video Recording
Live View on your Canon Rebel XSi allows composing images using the rear LCD screen, useful for precise framing and shooting from awkward angles. Access it via the Live View button. Note that autofocus performance can be slower in Live View compared to using the viewfinder.

The XSi also records Standard Definition video. To start recording, switch to Movie mode on the dial. Press the movie recording button to begin and stop. Remember that video quality is limited by the camera’s sensor and processing capabilities. Pay attention to available storage space on your SD card, as video files can be large. Experiment with different settings for optimal results.

Understanding the Built-in Flash & External Flash Options
The Canon Rebel XSi’s built-in flash is convenient for adding light in low-light situations, but it can sometimes produce harsh shadows. Explore flash settings like Auto, Fill-in, and Red-eye Reduction via the flash icon on the rear panel. Remember to allow the flash to recycle between shots.
For more control and better image quality, consider an external flash unit. The XSi supports Canon’s Speedlite flashes, offering features like tilting/swiveling heads, more powerful output, and advanced modes like E-TTL.
