#1 Red Eye Removal
One of the common problems we encounter while snapping digital photos is the red-eye effect as shown in the image below. This is caused by the flashlight situated close to the digital camera that is reflected prominently in creating this annoying effect.
One can also use online web tools for fixing red-eye effect by uploading the affected photos in batch. This methodology suits best for correcting the photos in bulk.
#2 Photo Sharpening
And, now comes one of the most common problems we encounter while optimizing a digital photo. A dull and blurry photo hides the fine details of the photograph. In such cases, you need to sharpen the photo which reveals the minute details of the photograph giving you a better, crisp and clear image.
Website owners using WordPress as their content management system can use this plugin to automatically sharpen the images on upload.
#3 Photo Cropping
A human eye is one of the most sensitive organs in our body. While viewing a large canvas our eye and brain work in conjunction and interpret the available image in different ways. If we want viewers to focus on a specific object within a photograph, one of the easiest methods is to crop that object and completely exclude the unwanted parts.
If you do not have a desktop photo cropping application, you can find tons of free online photo cropping tools one can use without any restrictions.
#4 Photo Noise Reduction
If a photo is affected by film grain, noise reduction is the way to go to get a crisp and clear version. Sometimes, the intensity of film grain is too much which almost spoils the entire image. Photos taken in dark and low light are often prone to film grain.
Smartphone users can use it both for iOS and Android platforms. A free online noise reduction web-based tool can also be used to quickly optimize your film grain affected photos.
#5 Background Blurring
Earlier we've discussed cropping a photo to achieve focus on an object. What if we do not want to trim the original photograph and still want a focus on the target object? That's where background blurring effect comes into play.
Most applications allow you to apply various types of blurring effects though you'll get the best results with Gaussian blur effect. This excellent application allows you to apply various types of blur effects without messing with complex photo editing steps.
#6 Removing Unwanted Objects
And sometimes, we do not want to blur or crop an image and rather look for hiding the unwanted object within an image. We can use a clone tool to achieve that. Almost every good photo editing application includes a clone tool to remove an object by filling it with the surrounding area.
Android users can use TouchRetouch app to easily remove objects from their snapped photos.
#7 Adjustment of Brightness & Contrast
Nothing can completely transform an original image than changing the brightness and contrast of an image. When applied, it can add life to a dull image. Fortunately, the process is dead simple when using popular photo editing applications.
Both Android and iOS provides brightness and contrast adjustment controls natively and one can instantly utilize them after snapping a photo. An online web tool can also be used for the same.
#8 Photo Resizing & Enlargement
A large photo can be resized to a smaller scale without many hiccups as it may not affect the quality of the photo at all. But if, the case is exactly the opposite, preserving the quality of an image is paramount. The smaller the image, the more challenging is quality preservation.
Mac users can use Pixelmator to enlarge their digital photos without losing the quality and crispness. Needless to say, Photoshop and GIMP users can also enlarge digital images without compromising on the quality.
#9 Photo Compression
Web publishers almost always use images within their content. Raw and unprocessed images are often bulky in size and if used as it is can consume a significant amount of bandwidth. Thankfully, lossless compression techniques can reduce the image file size without sacrificing the quality.
Its optimized algorithm yields a high compression ratio and yet preserves the quality of the image near to the original. In fact, all the images used in this post are processed using this service.
#10 Photo Annotation
And last but not the least is highlighting key objects and information within a digital photograph with the help of annotation and marking elements. Doing so completely transforms the image making it more interesting and meaningful.
If you're comfortable with regular photo editing applications, you can annotate the photos using GIMP and Photoshop. Just make sure you do not overdo it else it may spoil the photo instead of enhancing the visual.
