Before we go over how to retouch a photo, its important to know what photo retouching is. While the term photo retouching is pretty self explanatory, it is always a good idea to start with some basics for those who are new to the concept.
Photo retouching is basically retouching a digital photo. In other words, it is retouching or editing a photo that is in a digital format. Like a photo in the computer or cell phone or on some memory card or other storage device.
If you have an old camera that is not digital or if you have a printed picture that you wish to edit or retouch, that is also possible. However, you first need to scan the photograph with an image scanner, transfer a digital copy to your computer, then edit or retouch that photo.
You need an image editing tool like adobe photoshop or something similar that allows you to edit a digital picture. Using various functions of adobe photoshop, you can retouch or edit the image to whatever you like.
Adobe photoshop is a professional photo editing or photo retouching software. It costs money to buy the licensing for this specific photo editing tool. However, there are some free graphic design software that you can use to edit pictures as well. Depending on what you are doing, or if you just use the tool on an occasional basis, you might be better off going with a free software.
On the other hand, if you need photo retouching services on a regular basis, you might find it time and costs efficient to outsource your job to some photo retouching services provider.
