PhotoZoom Pro

BenVista’s PhotoZoom Pro is a dedicated photo enlargement program . A lot of available editing objects, as well as support for the latest technologies involving image processing, make PhotoZoom Pro an important addition to the professional workshop that processes digital photos.

PhotoZoom Pro is used wherever it is necessary to emphasize a fragment, a detail of a photograph, but the quality of the photograph cannot be reduced. Image interpolation algorithms use the innovative S-Spline, S-Spline XL, S-Spline Max, which allows for a significant increase while maintaining image quality at the level of most commercially available photo processing software. These algorithms also support JPEG image enlargement , which minimizes distortion and noise associated with lossy compressed images.

Smilla Enlarger

SmillaEnlarger is a free, lightweight photo resizing program. Modified photographs are processed using algorithms to sharpen the image and remove noise and distortion. The application does not have very wide functionality, so beginners will like it.

The process of changing photographs consists of several basic steps. At the beginning of working with the tool, you need to load the photo from the disk or external media – using the dialog box, the Drag & Drop method or the drop-down list. The program supports image files in the following formats: JPEG, PNG, BMP, TIFF, PPM. Then the image is cropped or enlarged to the desired size. In this case, we can use the ability to manually select the image area or automatically adjust the image to the specified coefficients (zoom level, width, height, maximum sizes, etc.).

The most important step is the choice of an optimization algorithm – there are 4 sets of predefined settings and the ability to manually adjust program parameters for pictures, such as the level of sharpness and sensitivity reduction. Before processing, you can use the preview function of the received image.

Other important features of the tool are:

  • work from the command line;
  • logging operations;
  • job queue (performing operations on photo collections in automatic mode);
  • image reduction without loss of quality;
  • display interface mode in a simplified version (without additional configuration options);
  • the ability to paste images from the clipboard.

The project is distributed under Open Source (GNU GPL) – has an open source code and release for the most popular operating systems. SmillaEnlarger does not require installation, just unzip the ZIP archive in any directory on your hard drive. The program contains brief documentation describing how to manage some functions.

FastStone Photo Resizer

Do you have to process several or several dozen photos manually, because you need a different format or other sizes than, for example, made by the camera? For the boring and monotonous increase in the size of many photos, use the FastStone Photo Resizer. The utility will help reduce or enlarge images. The program is small and is offered both in the installation and in the portable version – so you can always have it at hand.

FastStone Photo Resizer

The program is used for sequential image processing without loss of quality, which means that you can set the desired image output parameters only once, and they will be applied to all specified files. There are many possibilities:

  • resizing or cropping the entire image;
  • add color effects or color correction;
  • add texts and watermarks;
  • renaming files according to a specific template – for example, sequential numbering;
  • Search and change a specific line in the file name;
  • Saving the sequence of changes – useful if you often process similar photos.

FS Resizer supports the formats JPEG, BMP, GIF, PNG, TIFF and JPEG2000, it has the ability to recognize the directory structure, as well as a very convenient preview of the changes.

Example for resizing multiple photos

After starting the program in the window on the left, we see the directory tree of our disk. We select photos from it, the size of which needs to be changed – we mark them, and then click “Add =>”. Files will appear in the window on the right, and the entire operation will be performed on them. To go to the resize option, we need the tab “Use advanced options (Resize …)”, then the “Advanced options” button is activated.

On the “Resize” tab, select a size to reduce the weight of the photo – you can enter your own sizes or choose one of the standard ones available in the drop-down list. If the photos are vertical and horizontal, we also note “The width and height of the switch corresponds to the aspect ratio” – then the photos will be reduced in accordance with the length of the side, and not just its width.

EXAMPLE FOR RESIZING MULTIPLE PHOTOS

After selecting the option, click “OK” and return to the main program window. Now just select:

  • The path of the directory where the output files should be saved
  • possible scheme for creating their names.

Then click the “Convert” button and wait until the program finishes converting the files. In the process, information about your work is displayed, including the initial and final size of the photo, there is a current preview of the changes. When the program ends, you will have ready photos in the size that you have chosen.
