To enhance, correct, and edit your best pictures you can either purchase an expensive professional editor the likes of Photoshop or Corel Photo-Paint, or you can try PencilSheep first for free. This professional photo editor is available both online and as a standalone Windows app, and it comes with a clever combination of presets, layers, manual adjustment tools, HDR support, creative effects, and full GPU acceleration for all image-manipulation processes.

Professional photo editors that cost you nothing and that can be enjoyed by novice and pro users alike don’t come by easily. PencilSheep comes in a black-colored interface with buttons for the most common editing features and a set of menu options for filters, layers, masks, adjustment layers, and other advanced functions. A great thing about this interface is that it is identical in both the online and the desktop versions of the program. Regrettably, in both cases, you will need to click on any of the buttons located on the left-hand side of the main interface to know what they do, even though some of them are intuitive enough. From the user’s point of view, showing that information when hovering over them with our mouse would have been a more convenient and intuitive way of dealing with them.

Instead of listing here all the program’s functions and features, which you can explore on your own either online or by installing the standalone version of PencilSheep, highlighting its main differences with most similar tools may be a more effective way of reviewing this app. Thus, its use of full GPU acceleration is probably one of the main features that make it stand out from the plethora of image editors available out there. Editing high-resolution photos (note the program’s support for RAW images) is always a high resource-consuming task. To avoid image freezing or an overall slow responsiveness when dealing with heavy files, PencilSheep uses as much of the GPU as possible, which makes it significantly faster than most image editors. This is clearly visible in its real-time rendition of whatever changes you apply. Full GPU acceleration also allows the app to work with interactive filter layers instead of the traditional use of destructive filters, and to update any changes in those layers automatically.

PencilSheep offers you more features than many amateur and professional image editors. It will cost you nothing and, despite its lack of support for batch editing, will surely help you turn your best shots into works of art with just a few clicks of your mouse.
