Image Sharpening: Best Image Sharpeners to Sharpe Blurry Pictures

Is there any way can fix a slightly blurry photo? I have a photo that I love but it is a bit blurry.

It is frustrating to take blurry photos with cameras or mobile phones. And the most common reason to have a blurry picture is the incorrect use of shutter speed. The slower the shutter speed, the more chance for camera shake. To avoid blurry photos, you might need a faster shutter speed when you are photographing a moving project. Once the blurry photos have been taken occasionally, but you love it and do not want to lose the beautiful moment, so it is important to learn how to sharpen the blurry pictures effectively.

There are plenty of options (AI-based or traditional ways) for image sharpening, including online services, standalone programs, and plugins. You need to choose the right one depending on what you need to correct and what result you expect to get. Let’s see what image sharpeners you can use to sharpen blurry images and how they work.

The most common way to fix blurry pictures is to use an unsharp mask in Photoshop and other similar tools available. However, the effectiveness might be very limited. Nowadays, Artificial Intelligence has proven to be a game-changer in image sharpening, image upscaling, image enhancement, etc. While traditional methods detect and brighten edges, which creates halos, fringing, and an unnatural look, AI Image Sharpeners can deblur images without increasing digital artifacts and output the more natural result.

1. Luminar AI

Luminar AI is an intelligent image editing software for both beginners and professional photographers who want to edit images daily, as it provides many AI automated and customized routines and complex tasks. Luminar AI is also an intelligent image sharpening tool that lets you improve the crispness of your image with minimum effort. This not only allows you to draw attention to specific parts of your image using masking, but also is essential for neutralizing any blur produced by your lens or sensor. There are a number of options and filters you can use on Luminar AI to sharpen photos with medium effort.

The "Details" is a very useful tool when sharpening your images because of the array of options it provides you with. You can adjust the small, medium, and large details of an image independently, as well as control your details masking (helps define what areas you want sharpened, controlling the details) and sharpening masking (controls the zone in which details are amplified). Moving the slider to the right means enhancing the selected detail, to the left means lessening the effect. If the picture was taken in low light conditions or at a far distance, you can adjust the Details to bring details back.

The "Accent AI" on Luminar is used to analyze and control different parts of the picture for objects, structure, color, light and dark tones, and more in a single slider.

The "AI Sky Enhancer" filter is another easy-to-use filter that improves skies of landscapes by just using one slider.

Note: The sharpening filter helps focus softer edges in a photo to increase clarity or focus, but too much sharpening can give your photo a grainy look.

In other words, if you can not determine the type of blur, you do not know which option is best for your image, but automatic AI can do what you are not skilled at. Luminar AI provides great controllable options like Enhance AI and Structure AI. It does a great job to improve the overall aesthetic perception of the image.

1. Focus Magic

Focus Magic is software that uses advanced forensic strength deconvolution technology to literally “undo” blur. It can repair both out-of-focus blur and motion blur in an image, as well as significantly recover lost detail from blurry images. After downloading the Focus Magic plugin on your desktop, you can add the extracted file to the plugin folder of Photoshop or PhotoLine. Then add the blurry image to Photoshop and select "Focus Magic" from the Filters option at the menu bar. You need to determine the type of blur to select "Fix Motion Blur" or "Fix Out-of-Focus Blur", then manually control the settings like Blur Direction, Blur Distance, Blur Width, Remove Noise, and Accuracy until you get the best result.

2. SmartDeblur

SmartDeblur is a user-friendly tool for restoring defocused and motion-blurred images. With a newly added blind deconvolution module, it can automatically identify and recover images with complicated blur patterns. It supports two defect types: auto-detection of complex blur (blind deconvolution) and simple (Out-of-Focus Blur, Gaussian blur). Auto-detect Blur can automatically analyze the image and determine the blur path. It is suitable for common motion blur defects like camera shake and for small/medium defocus. Out-of-Focus and Gaussian Blur can remove a blur caused by mis-focus or Gaussian/defocus blur created by image processing software. They work in manual mode, so you need to select the right blur radius.

Verdict: Compared with Focus Magic, you can easily restore defocused and motion-blurred images with SmartDeblur, because it can help you automatically locate the area that needs to be improved.


3. Unshake

Unshake is an automatic deconvolver, also known as a "blind" deconvolvers which tries to recover what the original scene looked like, other than bringing out hidden detail by emphasizing changes (like edges) in pictures. Unshake needs to specify exactly how the picture was blurred in the first place, then the automatic deconvolver attempts to estimate how the picture was blurred and deduce what the original scene would have looked like. This is a very difficult task, involving automatically setting many controls.

Verdict: Unshake is an old image sharpener with many controls, so it is not that easy to use for beginners.
