![]() This setting was introduced in RawTherapee 5.5. If it is disabled and the combination of image dimensions, crop dimensions and resize dimensions is such that the image would need to be upscaled to meet your target, this setting will prevent it from being upscaled - it will remain at its current size. This setting controls whether the resize tool will also upscale your images, or only downscale. ![]() Setting the long edge to 1500 px for a portrait image of 2000×3000 px gives a resulting image of 1000×1500 px. Setting the short edge to 1500 px for the same image gives a resulting image of 2250×1500 px. setting the long edge to 1500 px for a landscape image of 3000×2000 px gives a resulting image of 1500×1000 px. The other dimension is updated according to the aspect ratio. Set the desired size of either the long or short edge of the image in pixels. Long Edge / Short Edge (Since RawTherapee 5.9).For the same bounding box and a portrait image of 2000×3000 px the resulting image will be 720×1080 px. for a bounding box of 1920×1080 px and a landscape image of 3000×2000 px the resulting image will be 1620×1080 px. Resize to fit the image within a box of certain width and height in pixels, regardless of the image orientation. Set the desired absolute width or height in pixels, regardless of the image orientation. Ranges from 0.01 (100 times smaller) to 16 (16 times bigger). You can specify what dimensions to scale to or by: It results in a smooth yet sharp and high quality image. It is meant to be used for everyday photography and in all cases except for the one described above. ![]() This method is not meant to be used for everyday photography. The result will be very sharp, but also very blocky. It is usually used when upscaling by squares of 2: 2x, 4x, 8x, 16x, etc. The "nearest neighbor" method of interpolation is meant to be used when you want to upscale an image in order to make some detail larger without introducing smooth blending between pixels. ![]() We narrowed the choice down to the two most significant: Resizing can be performed using various algorithms, each with its own strengths and weaknesses. Each of these offers documentation, explaining how to implement.Demonstration of the effects of the resizing methods "nearest neighbor" vs "Lanczos". Here are a few examples of popular image processing libraries for several leading coding languages. While these scripts or libraries absolutely require web development skills, they are often not difficult to use, and they can produce terrific results.įor example, one particularly easy-to-use combination is the Laravel PHP Framework and the Intervention Image library, which works with the GD Library or ImageMagick. Nearly every programming language offers some form of image processing, typically as a library. The most efficient and effective way to optimize product images for both beauty and fast loading may be to use a script. The exported image was still of good quality and small enough for relatively fast loading. For the sake of the example, imagine that this is a product image for a women’s “Sunset” tee. To demonstrate the new Adobe Photoshop generator, I downloaded Anthony Delanoix’ images available on SnapStock.io under a Creative Commons license. While this legacy feature is still available, the new generator does a better job of preparing images for use on the web, and will, typically, output smaller files for the same level of compression. In the past, many web designers used Photoshop’s “Save for Web” feature to optimize and compress images, like the product images being discussed here. Photoshop CC 2015, which was the most recent version of the software at the time of writing, also has a new and improved image generator for web designers. Radical Image Optimization Tool (RIOT) (Windows)Īdobe Photoshop CC 2015 is arguably the current best-of-breed software solution for photography manipulation.Some of these software image compressors must be downloaded to your computer, while others run from a website.Ī search on Google or Bing, will yield dozens, if not hundreds, of image compression tools. There are many paid and free image compression tools available. There are certainly many strategies for optimizing product photos, three of these include using image compression tools, using photo manipulation and processing software like Adobe Photoshop CC 2015, or using scripts in PHP, Python, or similar. (Width and height measurements are pixels.) Popfunk is less effective at optimizing images. Walmart and Hot Topic do a good job of optimizing product images, as shown in this table.
