The '''Canon EOS 750D''' (also sold as the '''Rebel T6i''' in North America and '''Kiss X8i''' in Japan) is a 24.2&nbsp;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.

Every photo is determined by three settings working together. Change one, and the others are affected.
Every photo is a balance of three things. Understanding all three is what separates snapshots from deliberate photos.

{{Quote|'''Visual demo:''' [https://i.imgur.com/0dj09Bb.jpg &#x25BA;&nbsp;See how sensor size affects field of view (comparison image)] — notice how the same lens covers a different angle depending on sensor size. [https://www.reddit.com/r/photography/comments/t5ldg/i_dont_think_i_have_ever_seen_a_better_example_of/ Original thread]}}
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'''.


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.

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

=== AF Point Selection ===
=== Picking an AF Point ===


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:
By default the camera uses all 19 points and picks for you. For precision:


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


{{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×).}}
<div style="background:#e8f5e9; border-left:4px solid #4caf50; padding:11px 15px; border-radius:0 5px 5px 0; font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,sans-serif; font-size:93%;">
&#x1F4A1; '''Macro / copy stand:''' Flip the lens switch to '''MF'''. Use Live View + the magnifier button (&#x1F50D;) to zoom 5× or 10× — lets you nail focus manually to the pixel.

== Makerspace Tips ==
 
=== Product &amp; 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


== Live View &amp; Video ==
=== Close-up &amp; 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


Press the '''&#x25B6;&#x25A0;''' switch beside the viewfinder to enter Live View. The screen flips out and rotates useful for overhead shots on a copy stand.
=== EinScan 3D Scanning Reference Photos ===
* Shoot the object before placing on the turntable — useful colour/texture reference
* Enable Anti-flicker: '''MENU → &#x1F4F7; → Anti-flicker shooting''' — helps under strip lights


* Touch the screen to focus on a spot
=== Workshop Events &amp; Documentation ===
* Pinch to zoom for manual focus check
* AI Focus · ISO Auto (cap 3200) · Av f/4–f/5.6
* '''Movie mode:''' turn the mode dial to &#x25B6;, press the red &#x25CF; button to record
* Articulating screen is great for floor-level or overhead angles
* Canon Camera Connect app + Wi-Fi = phone as wireless shutter remote

== 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.

----
 
== 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 (&#x1F50D; 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 → &#x25A6; → 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 ===
{{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.}}
 
----
 
== 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.
