I decided to find out what causes 'red-eye' in flash photography. Interestingly I found a simple but effective, (in my view), answer here in the CNET Forums;
It seems that the red-eye is caused because the pupil is wide open when the flash goes off, and the light from the flash reflects back off the retina which is full of blood vessels. With digital cameras this problem is exaggerated because the flash is so close to the lens of the camera when the photo is taken. It seems many professional photographers counteract this by having a separate flash gun offset from the camera itself. Then the light doesn't reflect directly back into the camera lens so much.
You can't do that with your own digital camera unless you want to invest in additional equipment, but perhaps you could minimise the wide open pupil by making sure there is plenty of background light in the room when you take a picture, or take your picture when your cat is not looking directly at the lens.
There is one thing that I, er... hesitate to mention. Mainly because I am in no way an expert in such matters and I don't want to cause any distress. But I see no easy way to say this.
I would have thought that yellow eyes is unusual. It may be that Himalayan cats are different and I must admit that Googling images of Himalayan cats does display a couple of cats with yellow eyes. So please take my words with a large pinch of salt.
However I know that looking into eyes is a good way of looking at the general health of the body of the owner, (of the eyes), whether it be human or animal. So, is this a time when a general health check of your cat might be a good idea?
As I say, I don't intend to cause distress, and hopefully I am way of the track here.
I have a beautiful white Himalayian Cat who is very photogenic but Im having trouble correcting her eyes. They arent red, they are glowing yellow, basically like a light bulb, I understand its from the flash but I cant take pics of her inside without it. I have a Konica Minolta Dimage Z10, I run Windows Vista Home Premium and I have been using Paint Shop Pro 8. I have tried the red eye fix on that but I cant get them to look natural, can anyone recommend any software that will fix the eyes easilly and so they will look natural. I can send pic if it would help.
