Usually, you can simply select the Red Eye tool and click on the red eye to fix a photo. Sometimes, a bit more effort is required, for example, when the rest of the face has a reddish tinge, the tool has a more difficult job deciding what is a red eye and what is skin.
Simple case:

1. Click on Red Eye Reduction on the Tools bar
2. Click on the red part of an affected eye for a fix (if the eye is small, first zoom in to enlarge it).
3. Repeat for the other eye.

Fine tuning:
Click on the Red Eye Reduction tool. On the Magic Wand toolbox that appears there are three sliders will be displayed that control the Red Eye tool:

• Threshold: the range of the pixels to be changed according to color and tonal values. The higher the threshold, the more surrounding pixels will be effected. If the standard settings for Red Eye cause colour to leak outside the eye area, reduce the threshold value.
• Power: the strength of red channel reduction. All red in the selected pixels is reduced to same level as blue and green (actually, the minimum of the blue and green channels) and then Power is also subtracted. The higher the value of Power, the less red the resultant image will appear.
• Red: Limits the affected pixels according to how relatively red they are. Set to a high value, less of the pixels within the selected range will be included when the tool is used. Set to a low value, most of the pixels will be affected. Technically, the tool is applied to all pixels where the red level is greater than the minimum of blue/green channels plus the Red Range value.

As with other image editing programs, PhotoRestyle can only use a file if it is saved in a file format that PhotoRestyle recognises. PhotoRestyle recognises a range of image file formats, including all the most important ones. If the file you want to open belongs to a format within this range you can open and save it directly in its own format, save as a native PhotoRestyle file, or change it to any of the other formats that PhotoRestyle supports.

The full list of image file formats supported by PhotoRestyle, along with their extensions, is as follows:

• PhotoRestyle (apx)
• Adobe tagged (tif)
• Alias/Wavefront (pix)
• Amiga IFF (iff, ilbm)
• Bitmap (bmp, dib, rle)
• Compuserve GIF (gif)
• JPEG Images (jpg, jpeg)
• Macintosh PICT Images (pct, pic, pict)
• Portable Bitmaps (pnm, ppm, pgm, pbm)
• Portable Network Graphics (png)
• Raw Images (raw)
• Targa (tga)
• ZSoft Paintbrush (pcx)

No matter where it comes from, the image has to belong to one of the above formats if you are to be able to open or save it in PhotoRestyle.
