You probably use your camera every now and then to capture those vacation or party memories. Pictures help you relive that time, so you want to make the shots as vivid and clear as you can. But sometimes, when you take the photo you don't have time to adjust the aperture and ISO and all that so the picture may not turn out great and may be blurry or noisy or have red-eye. The only option is to edit the photos on a computer. I will show you some free alternatives to Photoshop and some other popular image editing programs that cost money and a little bit of what they can do. You can choose which one has the tools you need or is convenient for you. I will also show how finalize and publish your photos on a disc or on the Internet.
