How to Adjust a Blog Photo’s Color in Picasa
Color in photos frequently needs a little adjusting before you publish it on your blog. For example, fluorescent lights tend to make photos come out greenish. With a little help from photo-editing software such as Picasa, you can turn your friends’ skin back to normal colors.
To adjust the color of a photo, follow these steps:
Open Picasa and, in the Library, double-click the photo that you want to edit.
The Editing screen opens.
Click the Tuning tab on the left side of the application.
On the Tuning tab, drag the slider bar below Color Temperature to adjust the color tone of the picture.
Color can be tricky to adjust. As a good rule, look for an element in the photograph that you know should be a particular color, and then adjust the overall color to make that element look right. Then, look at the overall picture and adjust, if necessary. Elements that you can use for the purpose include eye color, skin color, sky, and other consistent elements.
You can have Picasa make an educated guess about the color settings that you need by clicking the Auto Color button in the Basic Fixes tab. Click the Undo Auto Color button if you don’t like the results.
