Built in Flash stutters...

When taking photo in a low light or poorly lighted area, the built in flash stutters like a strobe light. It blinks rapidly when I hold down the button and it won't activate the shutter to take the picture. I have no problem when in well lit areas. I've tried adjusting the apeture but that doesn't work. Is it a glitch?

    I have the same problem and it is not just because of the low light - the camera used to take the same pictures (inside my house) and would either just be over or underexposed depending on whether the flash went off. The problem is it stutters and won't let you take the picture at all. It didn't do this before and it is not working correctly. Any advice would be appreciated.

    IT is the Auto-focus assist light, packing in...... well the proublem with the seemingly stutter with the flash any way.

Try resetting ALL in the menu, if it has a way to do that.

Then go through the menus and set everything to the way you want it.
If it has a flash setting..check what it is.
Setting the RED EYE setting ON may cause the flash to act like this.
Try turning off the RED EYE setting to OFF, especially when in a very dark area.
Auto-Focus should not have anything to do with the flash. It has it's own small focusing light especially for this, and should be reddish in color, if the auto focus is on.

Check to make sure that the battery is charged to full or the batteries are new and the correct kind, if replaceable. Low batteries can cause problems which are unpredictable, and hard to detect, and can lead one to thinking that there is a problem with the camera.

    In the previous post I said that the auto focus had a reddish light...sorry, I meant to say that the red-eye has this reddish color light when it is turned on.

    The auto focus should not have anything directly to do with the flash, that is because the flash operates many times faster than the motor which adjusts the lens could go. The camera will focus if there is no flash. Focus and flash are separate as far as that is concerned.

We are also having this proublem on my mother DSLR. After comparing the way the camera is working my camera also a 350D it becomes apparent that the proublem is that the auto focus assist light ahs stoped working for some reasen, as such best solution is for the short term any way use manual focus. As it becomes apparent that in low lighting the canon will often not focus through using auto focus regardless of if the lights working or not. Infact the beams fired by the flash seems to actualy help the auto focus fire, just means the flash is useless when taking photos of people. I mean who really wants 5 or 6 times more flashes fired into the face?

This is the camera trying to give itself enough light to focus with.

As it uses contrast to focus with you will get problems in low light conditions. There's no way round this I'm afraid except to light the subject better. As it's a digital camera and you're not wasting film, try manual focus and see what results you get.

    This is a difficult one. I'm not sure why it has started to happen. Have you tried to get a firmware update from Canon's web site yet? You can download it and update the camera with it via the USB cable. I won't give you a link as I believe the firmware changes from country to country. Another thing you might want to try is cleaning the contacts on the back of the lens . Use a dry cotton bud. Don't use any solvents or liquid of any sort.

    If all else fails I'm afraid it's going to be a trip to the dealer.

    Sorry I can't be any more help.

I purchasing this flash from b & h and want to know if it will sync with my studio lights slave function so both flashes will be fired at the same time? I figure I'll have to use the camera in manual...

Presuming you bought a shoe-mount flash for your Sony A900 and set the camera and flash to manual so there's no pre-flash to prematurely trigger your strobes, and presuming your studio lights have built-in optical slaves, you should be all set.

Ttl auto does not work

Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera.
INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control.
Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure.
When we start with the history of underwater TTL auto strobe, underwater camera?"NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera/housing).
A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly wired, automatic TTL flash control is usable with any TTL auto strobe like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync cable.
NIKONOS type 5 pin electrical sync connector and NIKONOS V with INON Z-22 strobe
Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. Some underwater housing for digital SLR camera has NIKONOS type electrical 5 pin sync connector as same as film camera housing. Since the housing has same NIKONOS type sync connector, existing film camera compatible underwater strobe has been considered compatible with a digital SLR camera via 5 pin sync cable but happened to experience error message on the digital camera or blackout on an image even the strobe worked. Why this happened?
This is because automatic TTL strobe system difference between a film camera and a digital camera.

The film TTL auto system makes single flash while digital TTL auto system employs pre-flash type making two to three flashes. Film TTL auto strobe system starts firing at the same time the shutter opens and reflecting strobe light from a subject is recived at a film. The reflecting light on the film is metered by the sensor to determine when to cease firing for correct exposure. This process takes only about 1/1000 second.
In contrast, digital TTL auto strobe system can not calculate adequate exposure based on reflecting light from a subject since image sensor (CCD/CMOS) reflectivity is comparably low comparing to a film. So digital TTL strobe system gives preliminary flash for very short period of time (pre-flash) just before the shutter opens metering reflecting light from a subject by the sensor to calculate necessary amount of light for correct exposure and starts emitting main flash at the same time the shutter opens. Canon E-TTL and Nikon i-TTL employs this system.

When we connect conventional film camera compatible TTL strobe to pre-flash type digital SLR via sync cable, the strobe makes full dump by pre-flash signal then the shutter opens before the strobe has been fully charged resulting in quite under exposed image only with ambient light. Even two time flash compatible strobe like INON Z-220 strobe, does not fully support a digital TTL and force to use Manual flash mode.

Film SLR:
A strobe starts firing at the same time the shutter opens and quenches firing when correct exposure has been obtained.
A film compatible TTL strobe connected to a pre-flash type digital SLR via electrical cable flashes does not support TTL auto exposure resulting in synchronization only with first pre-flash or totally uncontrollable.
The birth of digital fully compatible S-TTL S-TTL auto compatible INON D-2000 strobe and Z-240 strobe works in TTL auto mode by simply setting their main dial to S-TTL position. A film camera seems to depend more on photographer's skill, experience and feel since the camera does not allow checking images on site. A digital camera allows us to check images right after shooting and enable to try to shoot again as much as we like. And high capacity memory card further allows to shoot hundreds of images. The digital camera makes entry level of underwater photography getting down and nowadays more people buy a digital SLR camera and underwater housing even they have just started underwater photography. However underwater photography gets more difficult because underwater strobe does not work in TTL auto.
INON is among the first to support digital TTL auto system with "S-TTL" auto mode equipped D-2000 strobe and Z-240 strobe.
The proper name of S-TTL is "Optical Synch TTL". S-TTL enables to perform in TTL auto exposure as same as genuine TTL strobe from camera manufacture, based on camera's built-in flash light to use as a signal to be transmitted to a strobe. S-TTL uses digital camera's built-in flash light not as a light source but as like a controller to trigger S-TTL strobe.
The built-in flash of a digital camera makes weak flash (pre-flash) before main-flash to calculate exposure. This pre-flash is transmitted to S-TTL strobe to control the strobe to make pre-flash to a subject. The reflecting light from the subject goes through the camera's master lens to an image sensor then a processor calculates main flash light amount for correct exposure.?Finally the built-in flash makes main-flash which is transmitted to the S-TTL strobe to cause main-flash of the S-TTL strobe.

Digital camera's built-in flash lights are transmitted via an optical fiber to the
S-TTL strobe to make pre-flash and main-flash instead of the built-in flash.

My Nikon N65 flash leaves a dark spot on all my photos

I love that camera. There are several possiblities, If you are using the pop up built-in flash with a telephoto lens or a lens hood you'll get a shadow in your photos ususally at the bottom of landscape oriented shots. If you are using a flash unit attached it may have something interfering with the strobe possibly or it is turned. We have the same camera and have had the shadow issue in the past. The pop up just won't work if something is wrong with the "bulb" the only other thing is that is isn't going all the way up, check that also.

Program garage door opener

You must first erase what's in the memory.
1.) Simultaneously press both buttons 1 and 3 on the Audi's built-in remote. Hold them until the indicator light flashes (20 seconds or longer).
2.) Now hold your garage door remote close to the Audi remote.
3.) Simultaneously press and hold both your garage door remote button and the button you would like programmed. The indicator light will first flash slowly then rapidly.
4.) You may release both buttons once the light flashes rapidly.

Olympus evolt 410

this is when the camera doesn't have enough light for auto focus! to suppress it, disable the option "auto pop-up" in the settings menu of the camera. you then might risk unsharp images but strobing won't happen until you manually pop-up the built in flash.

to get rid of the whole thing, you can buy one of the olympus e-system external flashes like fl-36 or fl-50. these bring a red-light for auto focus assistance.
