Photo resizing involves changing the size of a digital photo to be used in a website or blog, or as preparation before using them in the internet. There are many reasons why you may choose to resize an image and there are numerous ways and techniques involved. Although the default resize mode available in most photo editors works just fine, it is not always the best. As a matter of fact, there is no best way to resize images. It all boils down to what you want to achieve out of the scaling process. There are several approaches used in photo resizing and even the experts are often in search of new ways to resize images. It is important to note the difference between resizing, scaling and magnifying. Resizing results in a change in size (bigger or smaller) and while this will leave the photo contents intact, there will be some changes in pixels and colors.
Effects of photo resizing
When you want to make a bigger image out of a smaller one, then resizing is your only way of achieving this. However, resizing photos to become bigger often results in blurry images. This is because the same amount of pixels available in the original picture is now spread over a wider area. There are some software applications that fill in the required pixels to avoid blurriness, but the original photo quality will almost certainly be superior when compared to the final resized image. On the other hand, resizing larger photos to become smaller often improves pixels and sharpness. The original pixels are now fit into a smaller space making them more defined and distinguishable. It is important to be very careful when resizing photos as the process can change your images in detrimental ways. Once the file is saved and you have quit the resizing tool, it is usually very difficult to reverse the resize image back to its original properties.
As aforementioned, there are hundreds of ways to resize and image depending on the tool you are using. Most tools that can open an image have options for resizing. They provide default resize and many other pre-fixed resizing properties although you have the option for custom resize. If you want top quality results, it is advisable to go for custom resize and manually input the specifications for scaling to see what the outcome looks like. However, you can still achieve perfect quality resized images even with the pre-fixed conditions. In Photoshop for instance, the default resize is “Bicubic (best for smooth gradients)” and other pre-fixed options include “Bicubic Sharper”, Bicubic Smoother, Bilinear and Nearest Neighbor.” When you open the image size feature, you will be able to change pixel dimensions and document size. This also allows you to control the pixel spread and reduce blurriness. Another trick you can use to preserve pixels and quality is to first make the image larger and then resize to a much smaller size. Although some of the pixels will be blurred, since the final image is bigger than the original, the end product will be much better than if you only enlarged the photo in one resize process. One of the easiest resizing process is to create an avatar from a large photo, you can easily do it at avatarmaker.net.
Things to note
Each tool has unique features available for photo scaling and resizing and there are many ways to change the size of a photo. Before resizing an image it is important to consider a few things based on what you intend to achieve. In most cases, photo resizing is not always the best thing to do as it has drastic, sometimes detrimental, effects on the final image. Avoiding the unpleasant artifacts produced by resizing is very important otherwise the image’s quality will be corrupted. Instead of wholesale resizing, you can consider slight edge shaving or general cropping to produce a more desirable outcome without actually interfering with the pixels and final quality. Nonetheless, sometimes there is no other option but to completely resize the image as cropping and shaving will get rid of some parts of the picture you may want to retain. It is also important to note that resizing will have no effect on the photo is the size of the original and the final image is the same.
There are several photo resizing operators ranging from geometry to re-sampling, scaling and magnifying. Before resizing your photo, it is advisable to make a copy of the original image in case you need it for another procedure. You can also find some of the top photo editors that allow you to maintain pixel spread and increase the count where necessary.
