How to Edit Photos on a Mac

By Hollan Johnson

All modern Mac computers come with iPhoto as part of iLife, the standard software package for Macs. The iPhoto program allows users to gather all their digital photos in one program and edit them easily. If you need to edit photos on a Mac then iPhoto is for you. Not only can it get rid of red eye, you can also crop your pictures and adjust contrast and saturation and turn your photos from color to black and white or sepia toned with one click.

Step 1

Open iPhoto, which is in your dock or your Applications folder.

Step 2

Select the photo you want to edit from your iPhoto library and click on the “Edit” button.

Step 3

Select the “Crop” tool from the toolbar at the bottom of the window. Drag the crop icon over the part of the photo you want to keep. The part of the photo you don’t want to keep will be dark. Click on the “Crop” button again.

Step 4

Select the “Red Eye” icon. Click each eye you want to remove red eye from and click the “Red Eye” icon again.

Step 5

Select the “Retouch” icon. Click on the place in your picture you want to retouch and click “Retouch” again.

Step 6

Select the "Adjust" icon. Make the photo brighter or dimmer with the “Brightness” slide bar. Make contrast higher or lower with the “Contrast” slide bar. Make the saturation higher or lower with the “Saturations” slide bar. Make the photo sharper by sliding the “Sharpness” slide bar.

Step 7

Close the “Adjust” window by clicking on the “X” in the corner.

Step 8

Click on the “Effects” icon. Choose which effect you would like to add to your photo and click on it.

Step 9

Click “Done.” The photo will save automatically in iPhoto.

Tips & Warnings

  • In the effects window you can make your photo black and white or sepia toned.
  • You can undo any edits by clicking “Undo Edit” in the “Edit” menu.
  • If you close iPhoto before you press “Done” your editing will still be saved.
  • Do not sharpen your photos too much or they will look pixilated.
