          Q: - How do I remove Red Eye.

          A: - A simple method is described below, I'm sure there are many others.

          i) First zoom into the eye

          ii) Select "Quick" mask mode from the Toolbox - Keyboard Shortcut (Q)

          iii) Select the "Paintbrush" tool - Keyboard Shortcut (B)

          iv) Select an appropriately sized brush from the Brushes Palette, ideally it should be soft edged

          v) Paint the effected area of the eye making sure not to overlap onto areas of skin and unaffected portions of the eye

          vi) Return to "Standard" mode- Keyboard Shortcut (Q)

          vii) Choose "Inverse" from the "Select" menu

          viii) Choose the "Sponge" tool from the Toolbox - Keyboard Shortcut (O) and set for 100% Pressure and Desaturate mode

          ix) Simply paint the selected area until the red disappears

          x) Finally choose "Deselect" from the "Select" menu

          The above approach desaturates the red whilst still retaining the highlight in the eye.

          A2: Another method:

          Select the red part of the eye with the marquee tool or Quick Mask.

          Use Image>Adjustments>Channel Mixer

          Make sure you are in the red output channel.

          Set the red source channel to 0%, and the green and blue to 50% each to compensate and hit OK.

          Thanks to all those who put forward solutions to this problem

            Health Warning About Red Eye (I'm seroius here)

            This isn't actually a Photoshop subject, but I just read a post in this forum about red eye that reminded me of the article posted below.

            I came across this one day at Healthcentral.com. It was an email question to Dr. Deal Edell.

            My reason for posting this is that since many of you are photographers, you may come across this situation-although it is rare-and could be instrumental in saving a child's life.

            >Can A Child's Photograph Show Eye Cancer?

            >March 16, 1999 E-mail question: The other day, you described the plight of Hunter Tylos daughter, whose rare form of eye cancer was discovered because her eyes did not reflect red in a photo flash. Would you say more? My five-month-olds eyes always flash white in the photos.

            >Dr. Dean: Well try to put a photo on the Web site so people can see what this looks like. Yes, we have saved some kid's lives by discovering the cancer this way.

            >If you take a photograph of a kid and one eye reflects red and one reflects white, go to the doctor immediately. This could be cancer of the eye. It could also be a cataract, or something else. But the message you need to get is that its never normal.

            >One woman called to say that after hearing my program, she took her child to a doctor along with a picture where one of the kid's eyes showed white and the other showed red. The ophthalmologist took a cursory look in the child's eyes and found no problem. The mother called me about this, and I said, Go to another doctor.

            >She went to another doctor who dilated the pupil, and sure enough, the kid had eye cancer. The first doctor did not dilate her pupil, which is inappropriate. When we last talked to the mother, her child was being treated in a hospital.

              Here is more information on this issue: http://www.healthcentral.com/mhc/top/003315.cfm

              >Considerations:

              The normal appearance of the pupil of the human eye is black. In flash photographs the pupil may appear red. This is known to photographers as redeye and to physicians as the red reflex and is entirely normal.

              >On occasion, the pupil of the eye may appear white. This is never a normal condition and requires immediate evaluation by trained specialists (ophthalmology).

              >On occasion, a cloudy cornea may produce an appearance similar to a white pupil. The causes of a cloudy or white cornea are different than those of a white pupil but are also significant and require immediate attention. Cataracts can also cause the pupil to appear white.

              --------------------------------------------------------------------------------
              >Common causes:

              retinoblastoma

              congenital cataract (may be hereditary or secondary to conditions such as congenital rubella or galactosemia, retrolental fibroplasia, and other diseases)

              intraocular infections (infections within the eyes)

              persistent primary hyperplastic vitreous

              retrolental fibroplasia (retinopathy of prematurity)

              Coats' disease (exudative retinopathy)

              Note: There may be other causes of white spots in the pupils. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as quality, time course, aggravating factors, relieving factors, and associated complaints. Use the Symptom Analysis option to explore the possible explanations for white spots in the pupils, occurring alone or in combination with other problems.

              --------------------------------------------------------------------------------
              >Home care:

              If a white pupil is noted, an immediate appointment with your health care provider should be made.

              >It is often appropriate to see an ophthalmologist for eye conditions. Ask your health care provider if you need a referral.

                I am including a couple more links concerning this issue. These are links leading to the National Institutes of Health webpage. NIH is a large government-run research facility located in Bethesda, Maryland.

                Although retinoblastoma is a very rare condition, it is also fatal if untreated.

                Thank you for your time. 8^)

                  HEALTH WARNING:

                  While redeye is very common in photographs, a white pupil appearing on the subject's photograph can be a sign of a serious health problem such as retinoblastoma, which is a tumor of the eye.

                  Although retinoblastoma is a rare condition, it is life-threatening if it is not caught in time.

                  The following links are provided for further information, including Visual examples of how this condition would look on a photograph.

                  These links lead to the National Institutes of Health's website. NIH is a large U.S. government medical research facility located in Bethesda, Maryland.

                  http://medlineplus.nlm.nih.gov/medlineplus/ency/article/003315.htm

                  http://www.nlm.nih.gov/medlineplus/ency/article/001030.htm

                  The following links lead directly to visual examples:

                  http://medlineplus.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/9313.jpg

                  http://medlineplus.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/17159.jpg

                  As you can see from the examples, this should not be confused with the pinpoint flash reflection that occurs on many photographs. The examples shown in the links appear as an obvious white pupil that should be black.

                  If the the pupil appears white, an appointment should be made with a physician immediately.
