Various factors can have an effect on the visual quality of photos captured by a wide variety of digital cameras. Technical limitations of cameras, coupled with changing conditions in which users take photos, results in a wide range of visual quality. Camera-related limitations arise from a combination of poor optics, noisy sensors, and the modest capabilities of mobile camera phones that are used to take photos in conditions that range from bright daylight to indoor scenes with incandescent light or even dark night scenes.<\/p>\n

If you have lots of spare time, one option is to spend hours trying to enhance your images by adjusting brightness and color, restoring sharpness, removing noise, correcting for overexposure or underexposure, etc. Furthermore, the results achieved will not only depend on your training and experience with the photo editing software, but also on the quality, condition and calibration of the monitor used. Manual fine-tuning is also time consuming, and as the amount of image content is constantly growing, there is an obvious need for automatic image enhancement<\/p>\n

\"VIESUS<\/a><\/p>\n

VIESUS\u2122<\/a> is a software application developed by Imaging Solutions AG that takes everyday digital camera images and enhances them to look more visually attractive<\/strong>. VIESUS first analyses the image data then automatically applies any processing steps as needed: fixing dull colors and bad color balance, removing digital noise, adjusting poor sharpness \/ blurriness, correcting for overexposure or underexposure, and more.<\/p>\n

Cloudinary provides an add-on for using VIESUS\u2019s image enhancement capabilities, fully integrated into Cloudinary\u2019s image management and transformation pipeline. With VIESUS\u2019s image enhancement add-on, you can extend Cloudinary\u2019s powerful image transformation and optimization capabilities by automatically enhancing images to their best visual quality.<\/p>\n

Automatically enhancing images<\/h2>\n

Cloudinary already supports on-the-fly transformation using URLs for resizing, cropping, applying effects, etc. Now you can also use VIESUS as an effect by setting the effect<\/code> transformation parameter to viesus_correct<\/code> (or e_viesus_correct<\/code> for URLs) which tells Cloudinary to dynamically enhance the image to the best visual quality using the VIESUS add-on.<\/p>\n

Take a look at the following photo of the Golden Gate Bridge in San Francisco that was uploaded to Cloudinary\u2019s demo account as golden_gate_side.jpg<\/code>. The original photo on the left has darkened colors, low contrast and poor sharpness, and looks like it was taken on an overcast day. In the VIESUS enhanced photo on the right, the brightness and contrast is increased and the colors appear sharper and more vivid, while the photo now looks like it was taken on a bright sunny day.<\/p>\n

Further image transformations<\/h2>\n

Visual enhancement using the VIESUS add-on can be mixed with any of Cloudinary\u2019s rich set of image transformation capabilities.\nThe VIESUS add-on can also enhance a generated image, so instead of improving the original large photo, you can separately enhance each thumbnail or cropped version you would like to display.<\/p>\n

For example, the following code generates and delivers a version of the uploaded golden_gate_side<\/code> photo as follows:<\/p>\n
