Photography Practice Guide
The more you experiment with light, movement, and composition, the more intuitive your camera will feel. The exercises below are designed to help you practice the concepts we discussed.
Understanding Exposure
Your camera exposure is controlled by three settings:
Aperture – how wide the lens opens
Shutter Speed – how long light enters the camera
ISO – how sensitive the camera sensor is to light
Think of these as three tools working together to create the final image. Think of it like a
math equation:
Aperture + Shutter Speed + ISO = perfect exposed image
*changing one of these variables will change the exposure
Aperture & Background Blur
A wide aperture (smaller number like f/2.8 or f/3.5) creates:
• blurry backgrounds
• more subject separation
• softer looking portraits
A smaller aperture (higher number like f/8 – f/11) keeps more of the image in focus. Great for landscapes and large groups of people
Tip: A wide aperture lets in MORE light, a small aperture lets in LESS light - this will factor into your exposure equation
Practice Exercise
Photograph a person or object, stay the same distance away from the subject. Take 3 images
1. Wide aperture (ex: f/2.8 – f/4)
2. Medium aperture (ex: f/5.6 – f/8)3. Small aperture (ex: f/11 – f/16)
Compare the images and notice how the background blur and depth of field changes.
Tip: to keep the same EXPOSURE, you will need to adjust the shutter speed or ISO to account for the change in aperture. If this is tricky, try this exercise in aperture priority
Shutter Speed & Motion
Shutter speed controls how motion appears in your photos.
Fast shutter speeds (1/500 – 1/1000)
• freeze motion
• great for kids, pets, sports
Slow shutter speeds (1/30 – 1/60)
• show movement or blur
Practice Exercise
Photograph anything that moves:
• Try 1/500 to freeze motion
• Try 1/30 to see slight movement
Compare the difference.
ISO & Light
ISO adjusts how sensitive the camera is to light.
Low ISO (100–200)
• best image quality
• ideal for bright outdoor light
Higher ISO (800–3200)
• helpful indoors
• introduces some grain/noise
Practice ExerciseTake photos at 2 different times of day - the most effective would be at noon and at dusk. Keep the same aperture and shutterspeed and only adjust your ISO.
• ISO 100
• ISO 800
• ISO 1600
Notice how the image brightness and grain change.
