- Image --> Enhance
- If you choose to enhance, this means that the program will automatically adjust color levels. If you like this, stick with it. If not, click on Edit --> Undo
- Image --> Resize
- Resizing your images can be amazing! Remember: You will want to keep aspect ratio, and if your image gets too large, you will lose clarity. Play around with it until you find the right size.
- Image --> Crop
- Want to crop someone out who no longer belongs? Or pick out your favorite part of a photo? Cropping allows you to select a part of an image, leaving the rest in the dust! Simply put the box around whatever you want to keep, and choose "apply." Again, you may "undo" if you don not want to keep the change. You will still have the original photo to work with.
- Image --> Transform
- Transform allows you to rotate your picture. You may also flip it, or mirror it. Try all functions, and choose one that works for you.
- Image --> Desaturate

- You can play with the color balance in your photo. Are you sunburned and want to look pale? Are you sick and green and wish to appear healthy? Are you freezing and blue but want to appear simply chilly? You can move the color balance back and forth until you strike your balance.
- Image --> Hue Saturation
- Similar to color balance, you can change the hue saturation. You may select varying degrees of hue, lightness, and saturation.
- Image --> Brightness/Contrast
