</div>
The 750D has an '''APS-C sensor''' (22.3 × 14.9&nbsp;mm), which is smaller than a full-frame (35mm) sensor. This means lenses appear '''1.6× more zoomed in''' than they would on a full-frame camera.

'''Rule of thumb:'''
=== AF Point Selection ===
* Faster = darker but sharper
* Slower = brighter but blurry


</div>
The 750D has '''19 cross-type AF points'''. By default it uses all of them (camera picks). For product shots or portraits, manually select a single point:


<br>
# Press the AF point button (top-right of viewfinder area, '''&#x25A6;''' icon)
# Use the d-pad or touchscreen to move the point
# Half-press shutter to lock focus, then recompose if needed


<div style="background:#f6f6f6; padding:18px; border-left:5px solid #388e3c; border-radius:10px;">
{{Tip|For macro/close-up work on a copy stand, disable AF entirely — switch the lens barrel to '''MF''' and focus manually using live view zoom (push the magnifier button &#x1F50D; to zoom 5× or 10×).}}

----
 
== Flash ==
 
The built-in popup flash (GN 9.4 at ISO 100) is adequate for fill flash or emergency indoor use. '''It is not flattering for portraits.'''
 
For makerspace use (3D scanning, product photography):
* Turn flash '''OFF''' — use diffused ambient light or a desk lamp
* Use the '''&#x26A1; Flash Off''' mode on the dial if you want the camera to still auto-expose without ever firing flash
 
External flash hotshoe is standard Canon E-TTL II compatible.

== Useful Tips ==
----


<div style="background:#fff8e1; border-left:5px solid #ffb300; padding:14px; border-radius:10px;">
== Common Makerspace Use Cases ==


'''✓ Half-press shutter''' to focus before taking photo.
=== Product / Object Documentation ===
* Use '''Av mode''' at '''f/8 – f/11''' for maximum sharpness and depth
* ISO 100–400 if you have decent light
* Use the flip screen for overhead copy-stand shots
* White balance: '''Custom''' from a grey card, or shoot RAW
* For EinScan objects: shoot at f/8 before and after scanning — useful reference


'''✓ Clean the lens, not just the screen.'''
=== Macro / Close-up Work ===
* Kit lens works down to ~25cm — for tighter work, use extension tubes (check lens bag)
* Manual focus + live view magnification (&#x1F50D; button)
* Use '''AI Servo''' + continuous burst if subject might move
* Aperture: f/8–f/16 for more depth (very shallow at close range)


'''✓ Use lower ISO before buying expensive lights.'''
=== 3D Scanning Support ===
* Shoot reference photos of subject before placing on EinScan SE turntable
* Use consistent lighting — turn off overhead flickering strips if possible (Anti-flicker mode: MENU → &#x25A6; → Anti-flicker shooting)


'''✓ If photos are blurry:'''
=== Workshop / Event Documentation ===
# Increase shutter speed
* '''AI Focus''' auto mode, ISO Auto (max 3200), Av at f/4–f/5.6
# Stabilize camera
* Use the articulating screen to get interesting low angles
# Check focus point
* Wi-Fi + Canon Camera Connect app lets you use your phone as remote shutter


</div>
=== Infrared / Modified Photography ===
{{Note|The 750D has a standard hot mirror (IR cut filter) installed. It is not modified for full-spectrum. If you need IR photography, check with the makerspace coordinators — this may be modified in future or an alternative body sourced.}}


== Makerspace Notes ==
----


<div style="background:#eceff1; padding:16px; border-radius:10px;">
== Known Issues ==


=== Good lenses for makerspace use ===
* '''Sensor banding in astrophotography:''' Horizontal banding artefacts visible under aggressive post-processing — inherent to Hybrid CMOS AF III phase-detect pixels. Not a defect, just a limitation.
* '''Dark circles (early units):''' Canon issued a recall/repair for a small batch of early 750D/760D units with circular dark patterns. Check serial number against Canon's list if shooting at small apertures in bright light.

Canon EOS 750D with kit lens 18–55mm

The Canon EOS 750D (also sold as the Rebel T6i in North America and Kiss X8i in Japan) is a 24.2 MP APS-C DSLR released in February 2015. It is available at the makerspace as a shared resource — great for product shots, documentation, macro work and experimenting with photography fundamentals.

The Mode Dial

The big dial on top controls how much the camera thinks for you versus how much you control manually.

The Exposure Triangle

Every photo is determined by three settings working together. Change one, and the others are affected.

△ The Exposure Triangle
◎ Aperture ⏱ Shutter Speed ☉ ISO
Controls how much light enters through the lens and depth of field Controls how long the sensor is exposed to light Controls the sensor's sensitivity to light

Aperture ◎ (f-stop)

Written as f/2.8, f/5.6, f/16, etc. Counter-intuitively: smaller number = bigger opening = more light + blurrier background.

Mall:Quote

f-stop Aperture size Depth of field Light Typical use
f/1.8 – f/2.8 ● Large Very shallow (blurry BG) ⭐⭐⭐ Lots Portrait, low light
f/4 – f/5.6 ◕ Medium Moderate ⭐⭐ Some General, kit lens sweet spot
f/8 – f/11 ○ Small Deep (most things sharp) ⭐ Less Landscapes, product shots
f/16 – f/22 ◌ Tiny Very deep Minimal Macro stacking, architecture

Mall:Note

Shutter Speed ⏱

Written as 1/500, 1/60, 2" etc. Faster = freezes motion. Slower = motion blur + camera shake.

Speed Effect Notes
1/1000 and faster Freezes fast motion Sports, machines in motion
1/250 – 1/500 Freezes normal motion Walking people, everyday use
1/60 – 1/125 Slight blur possible Handheld safe zone with IS lens
1/30 and slower Motion blur / light trails Use a tripod. Anything below 1/focal length = shake risk.
Bulb (B) Open as long as you hold Star trails, lightning, long exposures

Mall:Warning

ISO ☉

Higher ISO = brighter image + more grain (noise). Use the lowest ISO that gives a properly exposed shot.

ISO Noise Use when…
100 – 400 ✓ Clean Outdoors, good light, studio
800 – 1600 Slight grain Indoors, cloudy, dim makerspace
3200 – 6400 Visible grain Low light, concerts, candid
12800 – H25600 Heavy grain Emergency only — noticeably soft

Field of View & Crop Factor

Mall:Quote

The 750D has an APS-C sensor (22.3 × 14.9 mm), which is smaller than a full-frame (35mm) sensor. This means lenses appear 1.6× more zoomed in than they would on a full-frame camera.

Lens focal length Effective focal length on 750D Effective angle of view
18mm ~29mm Wide — fits in a room
35mm ~56mm Close to natural human vision
50mm ~80mm Short portrait length
85mm ~136mm Classic portrait
200mm ~320mm Strong telephoto

This is useful for makerspace documentation: an 18–55mm kit lens at 18mm gives you a workbench-width shot in the big room.

Autofocus

AF Modes

Symbol Mode Use it for…
ONE SHOT Single autofocus — locks when you half-press ◉ Still subjects, product photography
AI FOCUS Auto-switches between One Shot and Servo Mixed shooting, safe default
AI SERVO Continuous AF — keeps tracking a moving subject Moving people, action

AF Point Selection

The 750D has 19 cross-type AF points. By default it uses all of them (camera picks). For product shots or portraits, manually select a single point:

  1. Press the AF point button (top-right of viewfinder area, ▦ icon)
  2. Use the d-pad or touchscreen to move the point
  3. Half-press shutter to lock focus, then recompose if needed

Mall:Tip

Metering Modes

Controls which part of the frame the camera uses to calculate exposure.

Symbol Mode Description
⊙ Evaluative Analyses the whole scene — default, works 90% of the time
◔ Partial Reads ~9% at centre — useful for backlit subjects
◎ Spot Reads ~3.8% at centre — pin-precise, for tricky lighting
⊕ Centre-weighted Biases the centre but reads the whole frame

Live View & Video

Press the ▶■ switch beside the viewfinder to enter Live View. The screen flips out and rotates — useful for overhead shots on a copy stand.

  • Touch the screen to focus on a spot
  • Pinch to zoom for manual focus check
  • Movie mode: turn the mode dial to ▶, press the red ● button to record

Video specs:

Resolution Frame rates Notes
1080p (Full HD) 24p / 25p / 30p Best for general video
720p (HD) 50p / 60p Smooth slow-motion at 50%
480p (SD) 25p / 30p Small file sizes only

Mall:Note

White Balance

White balance tells the camera what true white looks like in your lighting. Wrong WB = orange/blue cast.

Symbol Setting Use when…
AWB Auto White Balance Default — usually fine
☀ Daylight Outdoors in sun
☁ Cloudy Overcast sky
💡 Tungsten / Incandescent Old warm bulbs (goes very blue — correct for orange cast)
💡□ White fluorescent Strip lighting (common in makerspace rooms)
⚡ Flash When using the popup flash
K Kelvin Manual colour temperature — for nerds and studios
□ Custom Set from a grey card — most accurate

Mall:Tip

Shooting RAW vs JPEG

RAW (.CR2) JPEG
File size ~25–30 MB per shot ~5–10 MB per shot
Editing flexibility Maximum — recover blown highlights, fix WB, etc. Limited
Straight out of camera Flat, needs processing Ready to use
Use for Product shots, portraits, anything you'll edit Quick documentation, web use

Set via MENU → ▦ (camera icon) → Image Quality

Flash

The built-in popup flash (GN 9.4 at ISO 100) is adequate for fill flash or emergency indoor use. It is not flattering for portraits.

For makerspace use (3D scanning, product photography):

  • Turn flash OFF — use diffused ambient light or a desk lamp
  • Use the ⚡ Flash Off mode on the dial if you want the camera to still auto-expose without ever firing flash

External flash hotshoe is standard Canon E-TTL II compatible.

Common Makerspace Use Cases

Product / Object Documentation

  • Use Av mode at f/8 – f/11 for maximum sharpness and depth
  • ISO 100–400 if you have decent light
  • Use the flip screen for overhead copy-stand shots
  • White balance: Custom from a grey card, or shoot RAW
  • For EinScan objects: shoot at f/8 before and after scanning — useful reference

Macro / Close-up Work

  • Kit lens works down to ~25cm — for tighter work, use extension tubes (check lens bag)
  • Manual focus + live view magnification (🔍 button)
  • Use AI Servo + continuous burst if subject might move
  • Aperture: f/8–f/16 for more depth (very shallow at close range)

3D Scanning Support

  • Shoot reference photos of subject before placing on EinScan SE turntable
  • Use consistent lighting — turn off overhead flickering strips if possible (Anti-flicker mode: MENU → ▦ → Anti-flicker shooting)

Workshop / Event Documentation

  • AI Focus auto mode, ISO Auto (max 3200), Av at f/4–f/5.6
  • Use the articulating screen to get interesting low angles
  • Wi-Fi + Canon Camera Connect app lets you use your phone as remote shutter

Infrared / Modified Photography

Mall:Note

Known Issues

  • Sensor banding in astrophotography: Horizontal banding artefacts visible under aggressive post-processing — inherent to Hybrid CMOS AF III phase-detect pixels. Not a defect, just a limitation.
  • Dark circles (early units): Canon issued a recall/repair for a small batch of early 750D/760D units with circular dark patterns. Check serial number against Canon's list if shooting at small apertures in bright light.

Lens Compatibility

Mount Compatible? Notes
EF-S ✓ Full native Designed for APS-C — widest angle options
EF ✓ Full native Full-frame lenses work fine, with 1.6× crop
EF-M ✗ No Mirrorless mount — incompatible
RF ✗ No New Canon mirrorless — incompatible without adapter
Third-party EF ⚠ Usually Sigma/Tamron Art series generally fine; older manual primes need adapter
