To be a bit more specific, this is the superposition of a very short exposure with flash, the clear sharp part overlaid by an underexposed long exposure shot (the blurry part) However, the amount of ...

My Lumix GH4 flash has stopped working — what can I do?

You ask for any advice, so I'm going to provide that. Your built-in flash seems like it's broken. So, you should ignore it and get a shoe-mount flash, since your camera comes with a standard hot shoe. ...

How to interval shoot in a pitch black room?

Angle the flash to bounce off the ceiling or a grey card by blocking the flash with a mirror. Simply shutter a bit slower or bump the ISO to account for the decrease in intensity. If it's a thin ...

Only in auto mode will the flash automatically pop up. If you are in the manual type modes, you have to hit the flash button on the top left side of the camera to pop the flash up.

How can I set three flashes at different output levels with a camera with only two flash groups?

Get more groups, or at least different triggers. Just me, but consider getting some additional gear. Picking up a cheap 3rd party CLS-capable flash, such as a Yongnuo YN-586EX (make sure you get the ...

Can I use burst mode with the pop-up flash on a Nikon DSLR?

Not with the internal flash. In continuous shutter mode, the internal flash will fire only once each time that you press the shutter button. Most of the Nikon manuals specify those exact words, but ...

Can I use burst mode with the pop-up flash on a Nikon DSLR?

Why does a lens hood plus built in flash cause shadows on the photo?

Because the built-in flash is too close to the camera body, and therefore the lens blocks its light in the frame, causing a shadow. The lens hood can't be made smaller, or else it would not be ...

My Lumix GH4 flash has stopped working — what can I do?

You have two basic options: Send it to a repair center to see if the flash can be fixed. Continue using the camera without the internal flash. Since the GH4 has a hot shoe, you can use an external ...

Why doesn't my D3100 take photos when the built in flash is popped up?

I'm guessing that the exposure settings are significantly different (darker) when the flash is up because it is expecting the flash to add a lot of light. If the exposure settings are dark enough that ...

Unable to trigger my Speedlite YN565EXIII via optical trigger using a Canon 750D (Rebel T6i)

Why won't my D3400 take flash pictures even when focused?

It seems, for whatever reason, that your camera can not detect when the flash signals a confirmation that is is charged and ready to take a shot. This may be an issue with the confirmation circuitry, ...

How do I activate the built-in flash on the Canon Powershot G5 X?

Yeah i got it... There was a plastic cover on the flash mount that was some kind of blocking the onboard flash. Removing the plastic cover unlocks all flash features.

Can I use a Canon 430EX III-RT without firing a pop-up flash?

If you don't have any additional triggering gear to get the 430EXIII-RT off-camera, then, yes, you have to fire the T6i's pop-up flash to trigger it in optical TTL slave mode. Without firing the pop-...

Why does my camera choose a higher ISO even when the flash is on?

Use a hot shoe flash. The D7200 is one of the later models with the latest way that Nikon Auto ISO reacts with flash (there have been three methods on iTTL models). If a hot shoe flash is used (a ...

How can I use only the external flash on slave mode without firing the built-in flash?

I have the same camera as you. Under built-in flash settings in the menu you need to select the "custom wireless function" and select only the external flash (and NOT the easy wireless flash setting)....
