Photography Essentials: Understanding the Basics
Sean Dalton · Travel Photographer
A tight, camera-first crash course that nails exposure and light but skips gear specifics and depth on editing software.
Sean Dalton's Photography Essentials does what its title promises: it strips photography down to the handful of ideas that actually matter when you are starting out, and it moves through them briskly enough that 90 minutes doesn't feel padded. The course opens with a short, honest framing device: Dalton says he spent his early years as a photographer feeling creative but technically stuck, unable to set his own aperture, and that learning the mechanics is what let his creative vision through rather than what constrained it. That framing sets up the whole course as a technical-literacy project rather than an inspiration reel, and it mostly delivers on that promise.
The exposure triangle, taught properly
The best stretch of the course is the explanation of shutter speed, aperture and ISO. Rather than just defining terms, Dalton walks through each setting's dual role: the light-control effect and the separate creative effect. Shutter speed controls brightness but also freezes or blurs motion, illustrated with the difference between a sports shooter's 1/2500 and a long-exposure city shot with light trails. Aperture controls brightness but also depth of field, with a clear rule of thumb: wide apertures like f/1.4 for an isolated portrait subject, narrow apertures like f/16 or f/22 for a landscape where foreground and background both need to be sharp. ISO gets treated correctly as the "last resort" setting, since raising it introduces digital noise that Dalton distinguishes from the more forgiving grain of film. The lesson on balancing exposure then ties all three together with real shooting scenarios, worked through camera setting by camera setting, which is exactly the kind of applied reasoning a beginner needs instead of another abstract diagram.
Composition, light and the weaker back half
Composition gets a reasonable pass through perspective (worm's-eye, bird's-eye, straight-on), leading lines, and the idea that good composition simply makes an image easier for the brain to parse. The lighting lesson is arguably stronger than the composition one, breaking light down into quality (natural versus artificial), strength (hard versus soft, governed by the size and distance of the source), and direction, with a clear recommendation to favor side or back light over flat front light for a more dynamic image.
Where the course thins out is the back half. The social media segment leans heavily on consistency, both stylistic and thematic, and on posting volume and engagement, which is reasonable advice but generic enough that it could apply to any creative niche, not photography specifically. The editing section walks through two real Lightroom edits end to end, including the S-curve technique in the Tone Curve panel, HSL desaturation of individual colors, and graduated filters used to fake window light, which is genuinely useful if the viewer already owns Lightroom, but the course never explains alternatives for anyone who doesn't.
The course project, shooting one ordinary object fifty times from different angles and distances, is a smart, low-cost way to force compositional range, and Dalton frames it as the single exercise that most improved his own eye. It is a good anchor for a course that otherwise risks being pure lecture. Overall this is a well-sequenced technical primer that earns its short runtime, best suited to someone who owns a camera and has never understood what the dials actually do.
The standout
The direction-of-light lesson, which argues for shooting with side or back light instead of flat front light, is the single idea most likely to change a beginner's photos overnight.
What you will learn
- How shutter speed, aperture and ISO combine in the exposure triangle to control both brightness and creative look
- How to read a camera's light meter to judge over- and under-exposure at a glance
- When to switch between single-shot and continuous autofocus and where to place focus for portraits versus landscapes
- How perspective, leading lines and diagonal lines shape a strong composition
- How to read light by its quality, strength and direction, and why side or back light beats front light
- A basic Lightroom workflow using the S-curve, HSL sliders and graduated filters to finish a photo
Best for: A brand-new photographer with a DSLR, mirrorless camera or capable smartphone who wants the technical basics explained fast without a 20-hour deep dive.
Skip it if: Anyone past the beginner stage who already understands the exposure triangle, or someone hoping for a real editing walkthrough in software they don't already own.
