iPhoto (Photos)

Practice #1

What is Photos?An Apple program for making light, color, and

clarity adjustments to photos. (It used to be called iPhoto). The program is good to use if you need to make quick/simple adjustments, but you

should use Photoshop for more complex changes to your photos.

First Steps: Import & Organize

1. Import photos by going to “File” > “Import” and selecting one or more photos to add to your iPhoto library.

First Steps: Import & OrganizeTo organize your photos: • Highlight them and click the “+” icon on the top

menu bar. • Select “Album,” and your highlighted photos will

be placed into a photo album together.

First Steps: Import & OrganizeDouble click on a photo to view it. Click the “Edit” button on the to menu bar to edit.

The HistogramThe histogram is a graph that represents all of the pixels in your image. On the far left, you have your blackest pixels (shadows). On the far right you have your whitest pixels (highlights). In the middle you have your midtones...which is everything else.

Lightest >< Darkest

The HistogramHistograms looks different in Photoshop and other photo programs, but they always have a similar shape.

If your histogram does not reach the end of the graph, it

means you don’t have any true black or true white pixels in the

image.

Clipped highlights(pure white)

If your histogram touches the edges of your graph, it means those pixels are pure black or pure white. When pixels are on the edge of the graph we say that the pixels have been

“clipped” or “blown out.” Clipping pixels is bad

because it causes a loss of fine details in your image.
