a | == 📷 Canon EOS 750D (Rebel T6i / Kiss X8i) == | ||
A beginner’s quick-start guide for the Makerspace. ''Less history, more shooting.'' | |||

=== ⚙️ The Makerspace Bit: Sensor & Tech === | |||
The 750D has an '''APS-C sensor''' (22.3 × 14.9 mm). This is smaller than full-frame, which means: | |||
* '''1.6× crop factor''' – a 50mm lens looks like an 80mm lens | |||
* '''24.2 megapixels''' – plenty for large prints or cropping | |||
* '''ISO 100–12800 (expandable to 25600)''' – usable range for most indoor projects | |||
* '''1080p video at 30/25/24 fps''' – good enough for documenting builds | |||
'''Key takeaway for makers:''' The crop factor is your friend for close-up project shots (less working distance needed), but it struggles in very low light unless you add workshop lighting. | |||

=== 🎛️ Just Tell Me What to Set === | |||
'''Mode dial to “P” if you want point-and-shoot.'''<br/> | |||
Want a bit more control? Try these: | |||
* '''Av (Aperture Priority):''' For blurry backgrounds. Set aperture to the lowest number (e.g., f/3.5) and let the camera do the rest. | |||
* '''Tv (Shutter Priority):''' For freezing motion (machines, people). Set to 1/250 sec or faster. | |||
* '''ISO:''' Keep on '''Auto ISO'''. The camera is smart enough. | |||
* '''Focus:''' Set lens to '''AF''' (Autofocus). Use the touchscreen to tap what you want sharp. | |||
* '''Picture Style:''' Set to '''🖼️ Standard''' or '''🌄 Landscape''' for punchy maker-project photos. | |||
'''Pro move:''' Flip the screen out and use '''Live View''' (the 📷 button near the viewfinder). Touch the screen to take a photo—like a giant phone. | |||

=== 🔆 Aperture (How blurry your background is) === | |||
[[File:Aperture_diagram.gif|center|300px|Aperture blades opening and closing]]<!-- Replace with your actual GIF file name --> | |||
* '''Small number (f/2.8)''' = Big hole, lots of light, blurry background | |||
* '''Large number (f/16)''' = Small hole, less light, everything in focus | |||
On the 750D: Hold the '''Av ± button''' and turn the main dial to change. | |||

=== 🔭 Focal Length / Field of View (How zoomed-in you are) === | |||
[[File:Focal_length_comparison.gif|center|300px|Animation showing same scene from wide-angle to telephoto]]<!-- Replace with your actual GIF file name --> | |||
* '''18mm''' = Wide. Fits the whole workbench in. | |||
* '''55mm''' = Zoomed. Just the detail on the PCB. | |||
* '''250mm''' (if you have the big lens) = Very zoomed. See the engraving on that chip from across the room. | |||
On the kit lens: Just twist the zoom ring. | |||

== 🧼 Makerspace Borrowing Rules == | |||
#️⃣ Always return with a charged battery (charger is in the camera case). | |||
#️⃣ Set lens back to '''AF''' and dial to '''P''' before you put it away. | |||
#️⃣ If the card is full, don't delete everything—just tell a steward. | |||
#️⃣ Yes, you can use the Wi‑Fi. Look up “Canon Camera Connect” app. 📱📷 | |||
