Red-eye is caused by the light from the flash reflecting from the back of the eye. There are several ways to eliminate or at least reduce the effect. One, as you've done, is to edit the photo after it's been taken. The red-eye reduction feature of the camera shines a light at the subject, causing the pupils to contract and thus reduce the reflection from the eyes.
A good way is to move the flash away from the camera. This causes the red reflection to go toward the flash, not the camera. Unfortunately, the D40x lacks the Commander mode to control remote flashes. Instead, you can use something like the SC-29 cord to move the flash away from the camera.
Another possibility to consider is to not use the flash at all. Bump up the ISO and see whether there's enough light for existing-light photography.
1) The red eye effect is due to pupil dilation. When the person is standing in dark, the pupils dilate to allow more light to enter the eye so that objects are visible. In such conditions if you try to take a snap then you might end up having Red eyes. What Red eye reduction technique does is that it flashes a series of times before the actual snap is taken and due the series of flashes, the pupil try to adjust by closing down and reducing the red eye effect, hence stronger the flash, less is the red eye effect. Also, there are bundles of software out there which can detect red eye and remove the same.. I am not sure, you might have received software even along with your camera that can address this issue.
2) The use of Speed-Lite 430 might not be always .. It depends on the conditions and distance of the object from the camera lens. Onboard lite should be enough to capture the subjects that are within 5-6 meters and to get rid of shadows where as if the surroundings are very dark then you might want to fallback on Speed-Lite 430.
3) The basic difference between the RAW and JPEG is that RAW is uncompressed format and you can do editing and compression at later time where as JPEG is a compressed format and you might not be able to do as much as you can do with RAW format. Unless you want to edit the images at later stage, you might not want to use RAW.
Please let me know if any further explaination is needed.. Till then Happy Photography :)
you can use Picasa2 to get rid of the red eye from your pics. however, this is installed on your computer and whenever you will take pictures, there will still be red eye. Picasa2 is very easy to use and you can get rid of the red eye in only matter of seconds.
If the red-eye reduction is turned on, and you can verify that the pre-flash is functioning, you may need to think about shooting technique. With ultra-compact cameras, the flash is necessarily placed close to the lens. This is the worst design possible to avoid red-eye. To reduce red-eye as much as possible, ensure the red-eye reduction system is turned on (and functioning properly), and get close to the subject. I mean "physically" close, not just close by zooming. Use as little zoom as possible. If the subject is small, move closer, without relying on the zoom lens to make the subject appear closer.
I know that it's possible to remove red eyes with different software, such as Photoshop. Doesn't take much time. Good luck with that, I don't think there's anyway you can change the way red eyes occur except using the blitz less.
I can help with the red eye - I've had the camera a year now and have only just found it myself!! - After you've taken your shot, review the picture and then press the Hold button, press the right side of the menu button, just as you would when switching through your pics. In the blue menu bar at the top you will see the red eye 'paint' symbol, press down on the menu button and it will 'red eye fix.
Do you mean, the AF Illuminator (the bright orange/red light that appears before the picture is taken)?? If so, all have to do is click on menu, scroll all the way to the right (into the setup menu) and go to the camera icon. From there, go down to the AF Illuminator and switch it from "Auto" to "Off".
while in record mode, press the flash/up button repeatedly until you are in red-eye reduction mode. red-eye reduction mode should greatly reduce the problem when enabled. If this does not work, the software that came with your camera (and most photo editing applications) include a red eye reduction/removal filter.
