PhotoGrab

PhotoGrab is a Windows application you can use to apply various effects for enhancing your photo collections, such as sepia and sunshine. It's specially designed for touch-supported devices that are running Windows 8, 8.1 and 10.

It has a Modern UI with large and flat buttons, which gets seamlessly blended with your Start Screen or Menu look. Because it's signed by Microsoft, it can be downloaded and installed from the Windows Store with one click.

The supported types of images which you can open and modify are JPG, PNG, GIF, BMP, DIB, JPEG and DIF. Only one picture can be processed at once, since batch mode isn't implemented.

To apply effects, you just have to click their buttons: sepia, grayscale, negative or sunshine. When it comes to the RGB channels, you can click and drag the red, green and blue channels individually to adjust the color levels.

Modifications are applied in real time. However, the original image doesn't discard the effects as you apply new ones, which means that any new filter will be put on top of the previous one.

A solution to this would've been an undo button that permits you to go back to the previous step, or at least a reset button to restart the photo manipulation using the original composition. Nonetheless, PhotoGrab doesn't integrate these features, which means that you have to reopen the current picture using the file browser if you want to reset.

If you're satisfied with all the changes, you can either overwrite the original picture or create a new one by telling the app which saving directory, file name and extension you prefer. Images can be saved in JPG, PNG, GIF, TIFF or BMP format, which means that PhotoGrab is also a file type converter.

All things considered, PhotoGrab seems to be on the right track, but it cannot be used as a reliable photo manipulation tool.
