Main Menu

The main menu functions as a browser to select the photos you would like to edit. Two icons on the upper left allow you to alter the thumbnail size and change the sort order between “Name”, “EXIF time” and “Date modified”. To select a file simply left click it once. Multiple files can be selected while holding down “Shift” or “Ctrl” during a left click. This makes the selection for batch processing easier. The first icon in the upper left corner opens a menu with the following entries:

  • Photo options: Allows you to rotate and edit your files while in the browser.
  • Program: Here you can open this help, change the program language and check for updates.
  • Paste to edit…: Opens an image from your clipboard.
  • Load project…: Open a previously saved project to continue editing.

The second icon opens a preview for your selected image. This can also be opened by double clicking an image file. The third icon opens the edit menu for you selected image. The fourth icon opens the batch processing menu for all your selected image files.

Photo editing

The first panel provides a quick way to enlarge or shrink an image with a fixed ratio. You can also set custom dimensions. The unit can be changed between “pixel”, “inch” and “cm”. The ratio remains fixed. Using “inch” or “cm” you can also select a resolution. With “Crop source…” you can select a part of your image you would like to enlarge. Photo BlowUp provides different algorithms for varying image sources, which can be selected under “Enhance edge/Sharpen”:

  • A high quality clear image: For source images with high quality, sharp, most details and no distortion /noise/ blurring.
  • A jpg image from webpage: For images from websites with visually compressed artifacts. During enlargement the distortion will be enhanced.
  • A graphic image (text, cartoon, …): For images with smooth and clear edges like vector-based images, texts and cartoons.

The option “Remove noise before enlarging” applies the noise reduction algorithm before the enlargement. After enlargement small details like skin structure, cloth and fur may be lost. “Add fake texture” tries to reapply those details. The strength can also be altered. “Add grain” makes the final result more natural looking by adding noise into the luminance channel. The strength can be altered as well.

Saving the photo

After you are done editing your photo you can save it by clicking “Save” in the lower left corner. Then you can either select a preset or create a new one. Creating a new preset, you can preview a comparison between the original photo and the editing result. You can also change the image quality, file size and compression.

Batch processing

The image list can be edited with the buttons in the lower left. The first panel in the upper right provides the same settings as the single photo editing. The other panel provides settings for saving your images. You can change the file format, save path, naming rules and switch between overwriting the original file.
