In other words, when a photo is upsampled, more pixels are added to the resolution to fill in the gaps with accurate values. Interpolation works by using existing information to estimate new values in unknown points and approximate pixels based on neighboring pixels. Upsampling is an image-enlarging process that relies on various algorithms to limit the loss of quality through interpolation. The resizing method will maintain the number of pixels and only change the size at which the image will be printed. That being said, it’s generally not recommended to enlarge an image by resizing it. Sometimes 150 PPI is just fine and you won’t notice any difference. It all depends on your image and the purpose of the print. The image will be larger, but the resolution might be too low to print the finer details. If the “Resample Image” option is disabled and you double the dimensions of the image, the resolution (measured in pixels per inch or PPI for short) will be automatically reduced from 300 PPI to 150 PPI. For example, in Photoshop you have the Image Size option where you specify the size of your image by changing the width and height parameters. We see many customers using a resizing tool when they should be using resampling instead.
Both methods will change the size of the image but in different ways and for different purposes. If you change the pixel count in an image, then what you’re doing is known as resampling. It doesn’t add any new data to the image. Resizing refers to changing the print size of an image while maintaining the same number of pixels. Resizing and resampling are two different techniques, and each one of them has its place in post-processing. The two terms are often interchanged and used incorrectly. In this article, we’re going to explore the concept of upsampling and the best tools you can use to turn your photos into high-quality prints. In any case, there’s a right way of enlarging your images and a wrong way. Or maybe you took a low-resolution photo using your phone and now you need to scale it up. Perhaps you want to create a large metal print from one of your photos to decorate your home. There are many reasons why you’d want to enlarge an image. In addition to resolution, file format, color profile, and ratios, you’ll need to consider enlarging your images. This step is crucial and shouldn’t be ignored, because the entire look of the final product depends on it. Graphic designers can easily scale Web graphics up to print resolution or rescale everyday images for large format printing and outdoor advertising.When it comes to printing, one of the biggest challenges is preparing your images.
Blow up an image tool professional#
These features make Blow Up 3 perfect for a professional photographer creating gallery prints from digital photos, as well as an amateur photographer creating a poster from a favorite snapshot. The interface allows you to preview your photos and provides zoom controls. In addition, Blow Up 3 can be used to clean up overly compressed JPEG images minimizing or even eliminating the blocky effect seen in photos that have been taken off of the web.īlow Up 3 features a batch process function, provides easy cropping with a crop to size tool and has a Settings tab that lets you easily choose a standard output size and medium, such as 8x10 Inkjet Matte Paper. Blow Up also supports 16, 32 & 64-bit images and is optimized for multi-core and multi-processor systems. It also supports most image modes, including CMYK.
In some cases, Blow Up can enlarge up to six times (3600% area) without obvious artifacts.īlow Up 3 includes advanced features such as photo grain controls, enlargement-specific sharpening and controls for output sharpening where users can choose a medium (paper type or Web) so Blow Up sharpens just the right amount. Like the previous version, Blow Up 3 makes advanced image scaling easy, preserves smooth, crisp edges and lines and creates four times (1600% area) enlargements from any image without jagged artifacts or halos.

Also for the sake of efficiency, Blow Up runs more quickly on both Mac and Windows computers. So you can work more efficiently, the interface has been simplified to include only what's necessary. While you can still run Blow Up with Photoshop, you can now also run it with Lightroom 2 or later and process photos by the batch.
This version of Blow Up features an improvement in image quality, such that edges are made even sharper without artifacts introduced by the computer.
