Easily fix spots and other problems in photos
Expensive programs such as Adobe Photoshop have a feature called content-aware fill, which allows them to fix spots and other problems in a photo with little work. The free online service Webinpaint has the same capability and lets you easily remove spots, blemishes, scratches, objects, and any other problems you may have in a picture. For example, in the picture below, I start off with an image with four big air balloons and one small air balloon in the middle. I think the image would look better without this small balloon, so I draw over the balloon and click the Inpaint button to remove the small balloon from the picture.
Once the changes are made, I can save the new photo and be done with a fairly difficult photo edit in a less than a few minutes. Inpaint is available online without having to download any software, or as a free download also available on their website.
