How To Capture Sharp Photos With Your Camera
In this blog post, I’m going to go over 5 points that I think are worth thinking about when trying to achieve sharp photos for your photography.
SHUTTER SPEED
Setting up a proper shutter speed on your camera is essential for getting sharp photos. Even when I’m shooting landscape or a stationary object, unless I’m using a tripod, adjusting the shutter speed is one of the first things I consider if I’m aiming for a crisp image.
I generally don’t follow any specific rule when it comes to how fast my shutter speed should be in relation to the lens’s focal length. When I’m photographing a fast object like a speedy car, I’ll bump up my shutter speed to a much higher amount than I would in a portrait session with a model posing.

Looking through my photos, I usually start anywhere between 1/320 to 1/640 with my current camera equipment and adjust from there.
Ultimately, the best way to figure out the best shutter speed settings that works for you is to be out taking photos and experimenting with your gear. Being able to adjust camera settings on the fly is an amazing asset for any kind of photographer.
UNDERSTANDING FOCUS
When I first started photography, I left the focus mode of my Sony a7R III camera on “Wide” because I would just let the camera do the work. While this is a focus mode that I still use for some of my photography, taking the time to practice other focus modes was incredibly helpful in getting more consistent and intentional sharp photos.
Learning the ins and outs of your camera can help you understand how continuous autofocus works with moving subjects or how using manual focus can provide a sharp image of a subject through a transparent surface (like glass).
An important tip I learned when doing lifestyle portrait photography (or any kind of photography that involves getting the model in focus) is to always do a few test shots before fully starting the session, and check the images to see if the focus is perfect. Make sure that your focus settings are what they would need to be when your model is moving. Relying on the camera to do all of the work and taking a bunch of photos without checking is a risk not worth taking.

APERTURE
The aperture affects the range of sharpness in your image. A large (or wide) aperture such as f/1.4 allows a lot of light into the camera sensor and has a small range of sharpness. Conversely, a small (or narrow) aperture such as f/16 allows very little light into the camera sensor and produces a larger range of sharpness across the image.
With that in mind, you’ll want to adjust your aperture accordingly depending on what you’re going for. Unless I’m taking a landscape photo and want the entire image to be in focus, or photographing interiors, I usually don’t go above f/7.1. As I mentioned above, I think it’s always best to go out and experiment with different apertures to see how you like to adjust it in correlation to your shutter speed since everyone’s different.
There are photographers that might like to shoot portraits at the widest aperture possible, like f/1.4. I usually end up starting around f/4.0 because I like including the environment in a portrait and I don’t want there to be too much foreground-background separation. At an aperture like f/4, it gives me enough light to be flexible with my shutter speed, as well.
