Portrait / Studio Photography
How do you create a professional portrait with just one light source? I’ll show you step by step how I approach this studio shoot
Sharpness starts with control. Discover how to truly master focus and capture images that are razor-sharp down to the finest detail.
It’s a question I get a lot – and for good reason. Sharpness is one of the most important yet most misunderstood parts of photography. Many people rely entirely on their camera’s autofocus, but truly sharp images only happen when you understand how focus works and how to stay in control.
In this blog, I’ll walk you step by step through how to create tack-sharp images – from autofocus to manual focus – with practical tips you can apply right away, whether you shoot macro, portraits, or landscapes.
Sharpness depends on three factors: focus, stability, and depth of field. These three work together. If one is off, your photo won’t be perfectly sharp – no matter how good your lens is.

The Canon R5 features incredibly fast and precise autofocus, but it’s up to you to decide how it focuses. Choosing the right AF mode can mean the difference between luck and control.
Perfect for still subjects. The camera focuses once when you half-press the shutter button. Ideal for landscapes or product photography.
The camera continuously adjusts focus while you hold the button halfway – essential for moving subjects like animals or children.
For portraits, I almost always use Eye AF. The camera detects and locks onto the eyes, keeping them tack-sharp even if your subject moves. On the Canon R5 this works beautifully, especially with the RF 70–200mm f/2.8L.
In macro photography, I often prefer manual focus. The depth of field is so thin that you’ll want full control over what’s truly sharp. Use the magnification feature in the viewfinder or on-screen to fine-tune your focus.

Rule of thumb: use a shutter speed of at least 1/focal length. At 200mm, that means 1/200s or faster. For macro shots, I usually go with 1/250s or faster to avoid even the smallest vibrations.
RF lenses with IS (Image Stabilization) are fantastic, but turn IS off when shooting on a tripod – otherwise, it can actually introduce micro-movements.
Select your own focus point instead of relying on the camera’s auto-selection. That way, you decide where the viewer’s attention goes – like the eye in a portrait or the antenna of an insect.
In Manual mode or when focusing manually, you can enable focus peaking. The camera highlights the areas in focus with red lines – extremely useful for macro or close-up photography.
Even your breathing can affect sharpness during close-ups. Hold your breath briefly while taking the shot or use a remote shutter release.
This helps prevent vibration caused by the mechanical shutter. Especially at high magnification, it can make a visible difference in micro-sharpness.

Your aperture determines how much of your image appears sharp. At f/2.8, the background becomes beautifully blurred – perfect for portraits. At f/11 or f/16, nearly everything is sharp – great for landscapes. But remember: a smaller aperture (higher f-number) means less light, requiring a longer shutter speed or higher ISO.
My favorite settings:


Repeat this with different apertures (f/2.8, f/5.6, f/11). You’ll quickly notice how dramatically it changes the look and feel of your photo.

Razor-sharp photos aren’t a coincidence – they’re the result of control, patience, and practice. Once you understand autofocus, use aperture creatively, and keep stability in check, every shot improves. For me, sharpness isn’t just technical – it’s creative. It guides the viewer’s eye exactly where I want it.
My advice: experiment with focus points, shutter speeds, and apertures. Review your images on a big screen and learn from each one. Before long, you’ll be focusing like a pro.
