For class today, we worked with Photoshop. Did you know more often than not photos online are photo shopped? Why must people Photoshop photos, you ask? People use Photoshop to get their point across. We looked at photos with a polar bear in the south pole. Sadly, polar bears are not found in the south pole. The point, though, of this photo is to demonstrate to your students that polar bears live in the cold climate.
One way to tell if a photo has undergone Photoshop is by looking at the light and shadows cast on or by the objects in the photo. In one picture we looked at, the man on the left had a reflection on a flash on his forehead. That same reflection was copied onto the figure to the right's forehead and was given a lighter feel.
You can also tell the photo underwent Photoshop by looking at the grain of the picture, and the contrast of a photo. If, in the same picture as referenced above, the man to the left's suit was zoomed into, you couldn't see very well because it was so blurry, and you zoomed in the same amount to the suit of the man on the right, a sign that the photo went through Photoshop would be that the right man's suit was crisper and not as blurry.
Photoshop is a useful tool because it helps teachers get their point across, but it is also good to know when a photo has undergone Photoshop to help your students understand what is true and what is not true.
