If you are not a professional photographer you might be intimidated by the complexity and price of some of the photo editing software out there. PhotoScape 3.6.5 is a free download that aims to be simple enough for regular users. This means that it is not as feature-rich as Adobe Photoshop or even Gimp, but you are aiming to make simple, fun alterations to your photos, or create neat projects with a photo editor then PhotoScape might be a good fit for you.
Many of the features in PhotoScape are pretty simple. If you are looking to make slight alterations to photos such as: resizing, adjusting color tones, cropping, capturing screenshots, adding frames, captions, text, random objects, speech bubbles, etc., then this is a great solution. However, there are also some advanced features to be found here as well. PhotoScape comes with a batch photo editor that allows you to manipulate multiple photos at once and an animated GIF creator for all of the imaginative folks out there. You can also print different lined paper templates for creating cool things such as calendars or music paper.
With how simple these programs have become, you don't need to be a graphic designer with a college degree anymore to make good looking photos. Photoshop is still the biggest in the market, but if you are looking for a simple, free alternative then give PhotoScape a try.
