I used the Burn Tool to enhance her facial features, and I used the Clone Tool to remove the blemish from her nose. I reapplied the levels by selecting a white and black spot on her fur, and then I applied an Unsharp Mask only on the kitten. I then used the Free Select Tool to select only the kitten in the picture. The Levels Tool, located in the Colors Menu in GIMP, allows you to pick a white and a black input level to rebalance the color, brightness and contrast of an image.įor the image above, I chose a shiny spot on the wood rack for the white level, and a black spot on the same rack for the black level. If you struggle with getting a clean line with the tool, you can select an area around the object you wish to select, then use CTRL + click to remove unwanted areas from the selection. I don’t recommend skipping this step, as the Free Select Tool is what enables us to remove the blurriness from the outer edge of the main subject of the photo. The Free Select Tool was instrumental in fixing this photo. Then I applied an Unsharp Mask from the Filters – Enhance Menu to just the butterfly. Then I adjusted the image using the Brightness-Contrast Tool, bringing the contrast up and the brightness down a little. ![]() I adjusted the Curves differently this time, bringing the values down on the left but not up on the right. Then I clicked Select – Invert to work on the leaves in the background. I adjusted each channel, red, green, and blue, down on the left, and up on the right, as shown below. It’s best to keep the Curves within the range of the histogram shown in the window. Then I used the Curves Tool to improve the brightness and sharpness of the butterfly. The Curves Tool in GIMP is handy for fixing all kinds of photographic problems, but it works particularly well with blurry photographs.įor this blurry photograph of a yellow swallowtail butterfly, I first selected the outer edge of the butterfly with the Free Select Tool. Fixing Blurry Photos with the Curves Tool The level of detail you would like to achieve is entirely up to you, but you can usually make dramatic improvements with the Brightness-Contrast Tool alone. I used the Clone Tool from the toolbar (the icon looks like a person’s head and shoulders) to sharpen the outlines of the dragonfly and the leaves, and the Burn Tool (by selecting the Smudge Tool, then pressing SHIFT + D and selecting Burn from the tool options) to increase the contrast of the dragonfly’s head and back. Then I selected the dragonfly with the Free Select Tool and used the Brightness-Contrast Tool to increase both the lightness and the contrast. Then I used the Free Select tool to select the fern-like leaves on the left side of the image, and increased the saturation and decreased the lightness in the Hue-Saturation tool. ![]() Then I used the Free Select Tool from the toolbar (the icon looks like a lasso) to select the leaves in the foreground, and reduced the saturation using the Hue-Saturation tool, also in the Colors Menu. This is much better than the Sharpen tool, which would add a lot of artifacts and grainy texture to the image without necessarily enhancing the detail. Original blurry digital photo of a dragonflyįor the above fuzzy photo of a dragonfly, I chose the Brightness-Contrast Tool from the Colors Menu, and set it on the Darken only – Multiply setting. In GIMP 2.10, the brightness-contrast tool has numerous options that can help fix blurry photos by improving resolution and clarity. The brightness-contrast tool in the Colors menu is one of the best tools for fixing all sorts of photographic problems. Fixing Blurry Photos with the Brightness-Contrast Tool I’ll explain why in the following sections. The temptation for the uninitiated is to go for the sharpen tool, but generally speaking, that is not a good idea. I always try different tools until I get the right effect. It’s best to never assume that one tool or another is going to do the trick for fixing blurry photos. ![]() If your distro comes with an out of date version of GIMP, I strongly recommend that you install the latest version, or use the Flatpak app for GIMP. Which of course means that the updates are also free. But alas, the latest version Photoshop does not run on Linux, so I always use GIMP for these types of photographic repairs. My husband is a Photoshop expert and we do have a subscription to Adobe Creative Cloud. Sometimes we take a picture that doesn’t come out quite right, but that we would like to rescue. Though it still works, it often goes astray. We have an aging Canon PowerShot digital camera which we bought around 2005. It can be difficult to impossible to fix these problems with a scanner or camera. Whether you’re scanning old photos onto your computer, or downloading images from your digital camera, you will probably encounter a few blurry photos.
