Getting tack sharp images is important for both professional and amateur photographers. Outside of intentional creative uses for blur, such as panning or shutter drags, photographers rely on creating sharp, crisp images. We prioritize the focusing system in our camera and lens purchases, we crank up the sharpen function in camera, we wield that sharpen Photoshop action to almost razor-like proportions, and more! When I first started in photography though, I was finding that the images weren’t as sharp as the ones I’d seen online and some of them were downright blurry and unusable (even if I tried to salvage it by making the image black & white). It is one of the worst things to come home from a shoot and find that all your images are not sharp.
In one of my very first portrait shoots, my go-to lens, the Canon 24-105mm f/4 was acting up and so all I had was my Canon 50mm f/1.4. I did the entire session on that 50mm, went home and was shocked and dismayed to find that 50% of the images were blurry. Turns out, I had forgotten to change the aperture and shot the entire session at f/1.4! Thankfully, the other 50% of the images were pretty good and the client was happy to have them. So, why are your photos blurry? Every photographer has taken a blurry photo. It happens to all of us, especially in the beginning when we are first trying to figure out our camera.
8 Reasons Why Your Photos Are Blurry
1. Camera Shake – Camera shake occurs when the photographer doesn’t hold still enough when the shutter is open and/or doesn’t use a high enough shutter speed for the focal length. In short, if the photographer moves when taking a picture, especially at lower shutter speeds, your images could come out blurry.
2. Motion Blur – Motion blur happens when elements in the scene are moving while the picture is being taken. This can be intentional, as in showing the movement in water or traffic. Or it can be unintentional, when the shutter speed is too low and you see movement in your subject.
Creative use of slow shutter3. Shallow Depth of Field – Parts of a photo can be blurry with a shallow depth of field. This effect is typically intentional, with the subject of the photo in focus and the background or foreground out of focus.
4. Missed Focus – Sometimes a photographer misses focus. This happens more often in scenes with moving subjects. Some cameras and lenses simply have bad autofocus performance. With each improvement in camera and lens technology, missed focus is less and less of a problem. However, a photographer still needs to train his or her instincts and use the right techniques to prevent the issue.
5. Air Quality – On a foggy day, a polluted day, or a humid day, particles in the air can affect the sharpness of a photo. This can lead to an artistic, dreamy effect if used intentionally.
6. Subject Too Far Away – In general, the further the subject is from the camera, the higher your chance of getting blurry photos. Chances of air particles interfering, camera shake, missed focus all go up.’
7. Light Quality – The quality of light can also affect the sharpness of the photo.
8. Misaligned Focusing System – Sometimes your camera or your lens needs to be recalibrated. For more information, see this article on how to recalibrate your lenses.
Tips to Avoid Blurry Photos
Use the appropriate shutter speed – Though many factors go into this decision, a good rule of thumb is to stick to the reciprocal of your focal length. This is called the reciprocal rule. So if you’re shooting at 200mm, keep your shutter speed at 1/200th or up.
Use a Tripod – If you need to drop to lower shutter speeds, use a tripod or monopod. In fact, you can get creative with slow shutter speeds and tripods by intentionally capturing movement.
Take Multiple Photos – Take multiple photos of the same scene or moment so that you can choose the sharpest photo later in post production.
Use Blur/Focus Correction Software – If you don’t have a sharp photo of critical moment, try fixing it in post production. There are tools in Lightroom and Photoshop that can help, like the sharpen tool. However, you may also want to explore software dedicated to fixing blurry photos.

Upgrade your camera – New camera and lens technology will generally result in better image quality and better auto focus. Many new mirrorless cameras also have Image Stabilization built into the camera, letting you drop your shutter speeds even lower without any camera shake. If blurry photos is consistency a problem, consider upgrading.
Getting blurry photos can be a frustrating aspect of photography, but hopefully these tips can help you achieve the sharpness you desire in your photos. If you have a blurry photo that you’d like to fix, you might also be interested in our article on Apps and Software to Fix Blurry Photos.
