Smartphones are so good now — do I really need a camera?
Smartphones are great for everyday snaps and social media. But cameras have unique strengths: ① Depth of field control — manual aperture for intentional bokeh still noticeably outperforms computational blur on smartphones. ② Low-light performance — a larger sensor captures more light, resulting in much less noise at night. ③ Interchangeable lenses — switch between wide-angle, telephoto, and macro depending on the scene. If you're just starting out as a hobby, a smartphone is a perfectly fine start. Consider moving to a camera when you hit the limits of depth-of-field or night photography.
schoolCompare camera typesAperture, shutter speed, ISO — which should I learn first?
Start with shutter speed — it's the most intuitive. Fast freezes, slow blurs. Next, aperture — the more open it is, the more the background blurs and light enters. ISO is last: raise it in dark conditions, but remember it introduces noise. Together these are the 'exposure triangle'. Change one, and you need to compensate with the others to maintain exposure.
schoolExposure triangle lessonDoes following the rule of thirds always produce a good photo?
No. The rule of thirds is a starting point. You need to know the rules to break them intentionally. Center compositions are powerful for symmetry, authority, and stillness. The rule of thirds works well for natural movement and breathing room. What matters is being conscious of 'why am I placing my subject here?' Analyzing your own shots after the fact builds skills much faster than memorizing rules.
schoolComposition lessonWhat should I buy as my first prime lens?
For Sony E-mount, the 50mm F1.8. For Fujifilm, the 27mm F2.8 (equivalent ~41mm). Both offer great bokeh and cover a versatile standard focal length for portraits and everyday snaps. If budget allows, the Sigma 56mm F1.4 is worth considering — it's optimized for portraits and bokeh quality is noticeably better.
schoolView buying guideShould I shoot in RAW or JPEG?
JPEG is fine when starting out as a hobby. The camera processes the image automatically, files are small, and ready to use immediately. RAW gives much more flexibility in post-processing — you can recover 2–3 stops of exposure and completely change white balance later. Switch to RAW once you start learning Lightroom.
schoolLightroom basicsWhich mobile editing app is best?
Depends on your goal. Snapseed — free, best feature completeness, local adjustments available. VSCO — rich film-style presets, great for community sharing. Lightroom Mobile — syncs with desktop Lightroom, RAW editing capable. Start with Snapseed for general use, VSCO if you're after a film aesthetic.
schoolMobile editing lessonDo I really need a tripod?
Essential for night shots, long exposures, and astrophotography. Not necessary otherwise. For handheld shooting, keep shutter speed above the reciprocal of your focal length — e.g., at least 1/50s for a 50mm lens. With built-in image stabilization (OIS/IBIS), you get 2–3 extra stops of leeway.
There are too many AF modes and I'm confused.
Just memorize two for now. ① AF-S (Single AF) — for stationary subjects. Half-press to lock focus and hold. ② AF-C (Continuous AF) — for moving subjects. Keep the half-press held and it tracks the subject. Each brand names them differently (Canon: One Shot/AI Servo, Nikon: AF-S/AF-C, Sony: AF-S/AF-C). Always start with AF-C for animals and children.
