I need help with what to do when I can see bright flashing lights or black spots in my right eye. It only started today and I am a bit worried. Please can you help?

Those Rear LCD TVs get bad light engine on some. Causes fuzzy spots size of quarter. Or sharp small bright spots looks like road map or 'stars'. Need new/rebuilt light engine.

it sounds like you are try to SEE the pre-flash. you'll never be able to do it with bare eyes. it's all so quick that to the human eyes it all looks instant. don't worry about it. if it working in TTL mode, it does all the pre-flashes it needs, you just to see them. speed of light is quite incredible :)

Are you using the red-eye setting? An initial flash causes the pupils of your subjects to contract, followed by a second full flash 1 second later.

The trouble is that the first flash is bright, and subjects think its all over so they blink, rub their eyes, look away, and even the photographer may be pointing the camera elesewhere by then.

It is better not to use that setting, and fix the red eye afterwards.
With the flash open, hit the right button until the eye icon goes away.

It does have to do with your sensors. Funny but I am having the same problem, but luckily for me I was able to find my manual. Look at the sending and receiveing units that are the protective "eyes" installed at the bottom of the garage door rails. One sould have a bright orange light (sending eye) and the other should have a bright green (receiveing eye). If either is dim or flashing that is where your problem is. The manual says to loosen the wing nuts and adjust the units up or down until both lights burn bright. If either is dim, it means there is an intruption in the wiring some where(my problem). Hopefully this helps.

First, here is why they are red or white spots:

The red is the reflection of your flash on the retinas of your subjects. The white are generally animal eyes reflecting back.

You will notice this on flash shots only and mostly when you use the zoom. The zoom uses a "narrow" field of view so the light that reflects back is "direct", instrad of at an angle.

The fix: Change the ISO setting (it is set too high). It is probably near the maximum sensitivity (3200?)... set it to 400 or so and try that for a while. 800 is probably the best general setting, but try 400 first.

Try not to use the flash unless you really have to, but only if the subject is less than 12 feet away. If no people are in the picture, you may use the flash for subjects greater than 12 feet.

this should work for you...

No worries, I think I can help you with this one.
I believe that if you are using your Samsung Digimax in either "Auto" or "M" mode you will only have the options of "red eye flash" or "no flash". BUT HOWEVER, if you select the "Prog" mode on the dial on top of the camera, you will have 4 flash options - "red eye flash", "auto flash", "slow flash" or "no flash".
I hope that this helps!

my toshiba 62HM15A has bright and dark flashes.

if ur key has the security chip in it, it possible that ur ignition switch isnt reading that chip right away. i mean as long as u can get ur car started try and not get too worried about it. it is possible that ur ignition might be goin bad so try to keep an eye on it and if it starts to get worse take it in.

Ok...once and for all I will explain the fix (in detail...which has been missing)...

1) Firmware updates do not fix this problem. I had this problem, and updated my firmware to the latest versons without success. Also, cleaning the light engine (or any other part) does not fix this problem. If you cleaned your TV and your problem disappeared, you had a different problem.)
2) This repair requies a special tool from Panasonic. The tool is part number LSUQ0100. It is light grey in color, and is roughly 7" x 5" x 1" in size. It has diagnostic lights on it, and a button to press to start the procedure. This tool is used to reprogram your EEPROM. Again, this is VERY different than flash upgrading your firmware.
3) To repair the TV, the repairman must remove the lower back of the unit and plug the long, 5-wire connector (5 individual wires terminated to one female connector end - reminds you a bit of an old-style CD-ROM audio cable used in computers) into a male recepticle on the light engine.
4) The procedure takes roughly 6-7 minutes to complete. The TV remains on during the procedure (yeah, I was a bit surprised too). About mid-way through the procedure, your colored ball-shaped blotches will just disappear....no on-screen progress bar, no bright flash, the spots just disappear in the blink of the eye.
5) CALL PANASONIC!!! They are standing behind these TVs, and are covering these in-home repairs free-of-charge - EVEN IF YOUR TV IS OUT OF WARRANTY. Mine was out of warranty by over a year. The Panasonic rep was very kind, but did explain that this is the only repair for these TVs that they will cover out of warranty, as it was a defect in the manufacture of the unit - all other repairs are at the expense of the customer.

Good luck to all - I hope this helps some of you!
Cheers to Panasonic for standing behind their products like this....you don't see that very much these days!

Thanks,
Chris

Generally, a Nikon AF body - lens needs something of contrast to focus on (i.e., the tux of a groom) and with a white wedding dress, the autofocus tends to go 'nuts.' You could pick a spot (a pew) to focus on and then turn AF off: during the walk-down-the-asle, just shoot when the person hits that spot. In a less-than-bright church, maybe your eyes and digital are not a prime match. You could return to a film camera -- the F100 does well in lower light.
