Arthur Brisbane said that “a picture is worth a thousand words”. Pictures have been used and manipulated for a very long time. The evolution of technology has made it possible for just about anyone with a cell phone, digital, camera and a computer to alter images.
Photoshop is a fairly common product that is used for professional and personal image retouching and modification. In a professional setting, images are often manipulated to appear to be more beautiful, thinner, fuller, brighter, sexier…. Photoshop is used to enhance an image to make it more appealing, dramatic, whatever the desired effect is. Photoshop can also be used to add and remove things from an image, essentially creating a whole new picture.
There are other tools that are simpler and cheaper (like FREE!) available for your use. In this course we discussed using Picasa which is part of the Google + suite. Picasa allows you to store, edit and distribute images and videos. The other advantage of Picasa is that there are several tutorials available online, again for FREE that are available to you.
High Dynamic Range Photography, or HDR, is a technique of image where it’s actually a composite of three different images. There is one image that is taken on a low exposure (exposure is how much light you let into your camera), one on medium and one on high. Then you combine these three images together to form a “new and improved” image that tends to be sharper, more defined and a greater depth of colour.
