Just Want to Shoot? ⚡ New here? Only read this box. Come back to the rest when you're curious. I want to… Do this Just take photos — I don't care about settings Turn dial to A+ and shoot Blurry background (portrait look) Dial to Av · set a low f-number (f/1.8–f/2.8) Freeze fast motion Dial to Tv · set 1/500 or faster It's dark and photos are noisy Try a lower ISO first · if already low, you need more light Record video Flip the switch to ▶ · press red ● button Photos are blurry Check: is AF on? Half-press shutter to focus before shooting. Use faster shutter if subject is moving. The Mode Dial The top dial controls the camera's autopilot level. Most people never leave the left half.

Set f/4 or f/5.6 and let the camera figure out the rest. You get creative control over depth of field without worrying about exposure. The Exposure Triangle Every photo is a balance of three things. Understanding all three is what separates snapshots from deliberate photos. ◎ Aperture Light & background blur ⏱ Shutter Speed Motion freeze or blur ☉ ISO Brightness & noise ◎ Aperture (f-stop) Controls how much light enters the lens and how blurry the background is. The unintuitive rule: smaller number = bigger hole = more blur + more light. f/1.8 → huge opening     f/16 → tiny pinhole f-stop Background Light Use for f/1.8–2.8 Very blurry ⬤⬤⬤ Lots Portraits, low light f/4–5.6 Moderate ⬤⬤ Some Everyday, kit lens f/8–11 Sharp throughout ⬤ Less Products, documentation f/16–22 Everything sharp Minimal Macro stacking ⚠ Kit lens (18–55mm) only opens to f/3.5 at wide and f/5.6 zoomed. For serious background blur you need a prime lens — grab the 50mm f/1.8 from the lens bag. f-stop animation showing aperture blades opening and closing Aperture blades physically opening and closing Side-by-side comparison of shallow vs deep depth of field Same scene · f/1.8 vs f/11 ⏱ Shutter Speed Controls how long the sensor is exposed. Faster freezes motion; slower blurs it. Speed Effect Notes 1/1000 s+ Freezes fast motion Machinery, sparks, sport 1/250–500 s Freezes people Safe everyday speed 1/60–125 s May show slight blur Handheld safe zone (IS lens) 1/30 s and slower Motion blur / streaks Tripod required Bulb (B) Open as long as held Light trails, astrophotography ⚠ Flash sync limit is 1/200 s — shoot faster with flash and you get a black band across the frame. Grid of photos showing same scene at different shutter speeds 1/1000 s → 1 s: same scene, same light Animated gif showing motion blur difference at different shutter speeds Real-world motion blur difference ☉ ISO ISO makes the sensor more sensitive to light — but higher sensitivity = more grain (digital noise). Use the lowest ISO that gives a correct exposure. ISO Noise Use when… 100–400 ✓ Clean Outdoors, studio lighting, bright workshop 800–1600 Slight grain Indoors, dim ambient light 3200–6400 Visible grain Dark room, no other option 12800–25600 Heavy grain + soft Emergency only — image quality drops noticeably Field of View & Crop Factor The 750D's APS-C sensor is smaller than a full-frame (35mm film) sensor. The practical effect: every lens acts 1.6× more zoomed in than it would on full-frame. This is called the crop factor. Lens focal length Acts like on 750D Typical use 18 mm ~29 mm Wide — fits a full workbench in frame 35 mm ~56 mm Close to natural human vision 50 mm ~80 mm Flattering short portrait 85 mm ~136 mm Classic portrait / detail 200 mm ~320 mm Strong telephoto / distant detail 📌 The 18–55mm kit lens at 18mm is wide enough to fit the full CNC table or EinScan turntable in frame from ~60–80 cm away — good for documentation shots. Autofocus AF Modes Mode Behaviour Use for ONE SHOT Locks focus when you half-press ◉ Still subjects — product shots, copy stand AI FOCUS Switches automatically between modes Mixed / unpredictable subjects — safe default AI SERVO Continuously tracks a moving subject Moving people, machines, action Picking an AF Point By default the camera uses all 19 points and picks for you. For precision: Press the ▦ AF point button (top-right of viewfinder) Use the d-pad or tap the screen to move the active point Half-press shutter to lock, then recompose if needed 💡 Macro / copy stand: Flip the lens switch to MF. Use Live View + the magnifier button (🔍) to zoom 5× or 10× — lets you nail focus manually to the pixel. ☀ White Balance Tells the camera what counts as true white. Wrong setting → blue or orange colour cast everywhere. Symbol Setting Use when… AWB Auto Default — works in most situations ☀ Daylight Direct sun ☁ Cloudy Overcast, open shade 💡 Tungsten Warm bulbs / incandescent □💡 White Fluorescent Strip lighting (most makerspace rooms) K Kelvin (manual) Full colour temperature control □ Custom (grey card) Most accurate — set from a reference card Under the makerspace fluorescent strips: use White Fluorescent — or shoot RAW and correct in post. Makerspace Tips Product & Object Documentation Av mode · f/8–f/11 — maximum sharpness front to back ISO 100–400 under studio lamps; bump up only if needed Flip the screen out for overhead copy-stand shots White balance: Custom or shoot RAW for most accurate colour Close-up & Macro Kit lens works down to ~25 cm · use extension tubes (lens bag) for tighter work Flip lens to MF + use Live View magnifier for hair-precise focus f/8–f/16 recommended — depth of field gets very thin at close range EinScan 3D Scanning Reference Photos Shoot the object before placing on the turntable — useful colour/texture reference Enable Anti-flicker: MENU → 📷 → Anti-flicker shooting — helps under strip lights Workshop Events & Documentation AI Focus · ISO Auto (cap 3200) · Av f/4–f/5.6 Articulating screen is great for floor-level or overhead angles Canon Camera Connect app + Wi-Fi = phone as wireless shutter remote Useful Lens Options Lens Why 18–55mm f/3.5–5.6 (kit) General use — fits wide scenes 50mm f/1.8 Cheap, sharp, cinematic background blur Macro lens PCBs, components, small objects Known Quirks Astrophotography banding: Horizontal stripes appear under aggressive post-processing — an inherent limitation of the Hybrid CMOS AF III phase-detect pixels. Not a defect. Dark circle issue (early units): Canon repaired a small batch with circular dark patterns under certain conditions. Check serial number if shooting small apertures in bright light.
