How to reset ?


Some cameras have the option to do it with in the menu (find flash control>clear flash C.Fn) Otherwise if your camera does not have this then if yuou just take the batteries out for around 30 seconds to a minute that should do it.

My SB600 seldom firing when triggered manually on the red flash button. Only 2 or 3 times flashing after 30 attempt. Tried with new battery but same problem occured. Help.


If you are firing the flash manually it's giving full burst each time and the battery needs to pick up the charge from the bottom. So just numbers her for an example with a full set of batteries you manually flash, first burst takes 5 seconds to charge flash again it'll take 10 seconds, if you flash it again before that 10 seconds it'll now take 20 seconds and if you push that button again it might misfire because it just can't get the power up high enough to fire it. The flash isn't a studio strobe which is plugged into an outlet, you are working with battery power and each time you flash those batteries are under a huge load and each time you fire you kill them a little more I'm surprised you are getting 30 flashes from those batteries. My guess at full power you are going to start having problems after about 12 to 15 flash bursts and it's a rapid down hill drop in performance from then on. If you took those batteries out of the flash after that series of 30 flashes I'll bet they are hot. What you can do to help is set the system up with Nikon's wireless transmitter and utilize the new i-TTL system then you are taking performance.

I have purchased an Ikelite AF 35 strobe to use with my Sony DSC-TX1 camera and underwater housing. Even with the strobe set to the lowest setting, the photos I take with the camera set to 'housing on' are...


akdenny, have an af35 myself and know from experience the issue is very likely to be the way you have the block out for the cameras flash. if you block it by having the tape inside the housing it confuses the af35 to fire at a higher setting. from what i can gather it senses the strength of the camera flash and adjusts. I get the best results with the blockout on the camera supplied diffuser, stops the flash camera going forward and gives plenty of light to get the af35 to fire right. to blockout i just use some black tape , fabric tape seems to stick well.
you will still need to set the auto level setting.
hope it works out, i find it a great flash. and the guys at ikelite very very helpful.

Pentax K110d flash trigger problem, I have 2 flash trigger strobes set up and a flash on the hot shoe of the camera, but with shutter release the trigger strobe lights fire but do not show in the pic, only...


Your camera uses a PTTL flash system. That means the flash on the camera fires a "pre-flash" to set the exposure and then the main flash. Your flash trigger strobes are reacting to the pre-flash and firing before the shutter activates. This all happens in a millisecond.

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.

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 Hayward Colorlogic pool light is flashing like a strobe light


That particular swimming pool light has a power-cycle feature that allows you to change the way your light illuminates your pool simply by turning it off and on. A strobe like effect is one of these power cycles. To change it, simply turn the switch off and then turn it back on within 10 seconds. It should reset to another cycle. It is is left off over 60 seconds, it resets to the first cycle, which could be the strobe. If cycling doesn't solve the problem, your bulb has probably malfunctioned and you are going to have to have a repair tech service it.

R707 Fails diagnostic test 10 (strobe)


I found my answer to this on another board. Remove the battery and SD card. Use a paperclip to press in the small siver dot above the + sign for about 10 seconds. This resets the firmware.  It worked for me, hopefully it will work for you too.

Studio Strobe not firing with Coolpix


The Coolpix line of cameras require a "tip positive" sync connection to an external strobe unit (when using the Nikon AS-15 Flash Sync Adapter). On some external Studio Strobe units the sync polarity is easy to change because of the type of plug: On this type of connector simply turn the plug around and insert it with the male pin connectors in the other holes. Other types of connectors (such as the standard "phono" plug) are not generally changeable by the user. If the Coolpix does not fire an external strobe check with the strobe manufacturer for sync polarity info.
