Some side information.
When you have made alot photos and you need to check them one by one if they have red eyes this may take you a while.
Because we know red eyes are being caused by the flash on your camera it may be best to select only the photos which are made with flash.
How can you do this ?
On the top right of Picasa there is a searchbar. When you type "Flash" in the search Picasa will only show you photos which are made with flash.

How does Picasa know this ?
Well, this is noted in the properties of each photo.

When you rightclick a photo and choose "Properties" in the dropdown menu this will open a extra window where you can find all the properties of the currently selected photo and also if you did or didn't use flash.

Auto contrast/ Auto color

By using the button "Auto color" you automaticly remove the heu and after the colorbalans will be restored while the values for contrast and brightness will stay the same.
By using the button "Auto contrast" you will automaticly set the brightness and contrast to a optimal level while the color values will stay the same.

If these values are perfect remains the question but nevertheless will bring you in the right direction.


We can use the "Retouch" button to correct small irregularities in a photo.
As a example i have a photo from a teenager with some pimples and spots.
With the simple retouch button you can remove all these spots and make the face as clean as a baby.

To do this click the "Retouch" button. In the retouch window first select your brush size. The smaller the brush the more precise you can work.
Then select the area you want to retouch.
Zoom in on the area you want to retouch by moving the scrollbar to the right.
Keep the Ctrl-key down on your keyboard to change the position of the photo in the windows. This is also called "Pan".

Next click on the area in the photo which will replace the retouch area.
You can do this as many times as you want in a photo.
