I've had an NX1000 for more or less one year now, and I use it mainly to shoot landscapes and outside things. I wanted to shoot some people recently, and I had to use flash. And then things got weird. I don't know why, but sometimes, the flash is simply not detected by the camera. This can be fixed by removing and reattaching it, it's not a big deal. The real problem is that if I take a photo with the flash, it often looks like this :

Way too much white in this picture


(the shutter speed was 1/15 of second)

How can I avoid this ? If I remember well, I was on P setting (so I could force flash to be used). Everything (including ISO) was on Auto.

Weird thing : If I take the exact same shot just seconds after, it works quite well, resulting in a good photo.

Does anyone have an idea to fix this?

  • What kind of flash are you using? What specific model? Is it even compatible with your camera in automatic flash mode?

  • It is the flash that was delivered with the camera in its box so I guess it is ! Dec 25, 2015 at 10:17

Check page 77 of the manual of your camera there is information about "Adjusting the flash intensity". By adjusting the itensity to min -1 your flash will produce less light so the photo will be less over exposed. by trying different settings you will get a good exposure.

Camera manual

  • I had been looking for the flash intensity setting menu for a while ahaha. And actually, setting it to -1 really makes it better, at least it did for some random shot. Thanks. Dec 24, 2015 at 13:38

I don't know your camera, but it is likely that the flash is preset to assume a given exposure (and ISO). A common value would be 1/125 (and 100). Anyway, test with one, or both, of those values, in that direction, and you probably end up getting it right.


The ‘P” mode is not completely an Auto Mode but one which uses algorithms to pick a pre-determined setting based on the Exposure Value when the light hits the sensor.

From here the Camera only sets the following two;

Aperture Value

Shutter Value

The User has control over the following main settings that will enable a correct exposure

ISO - Reduce this from 800 to 200/400 and take a shot

Exposure Compensation - Move to the left and it will make your image darker and balance out the flash - However, this will not increase the shutter Value which at 1/15 is too low. You should ideally be looking at a shutter value of 100 or above.

Flash Compensation - Move the slider to the left to bring down the power of the flash.

Program Shift - Rotate the Navigation Dial at the back of the NX1000 clockwise, this will increase the Shutter Value and Decrease the Aperture Value - Most likely your best option

Regarding your concern about the flash firing correctly a few seconds later, that is most likely due to the flash not being back at full power. Once it is fully charged, you will then again get an over exposed image.


I am not sure if you still need help with this. I am going to explain a short trouble shoot you can do. From what I see, your camera is metering without taking the flash into account. You take a picture, properly metered by the camera, for example your indoor shot posted above, at 1/15 shutter, 3.5 aperture, with an ISO of 800 resulting in a well illuminated picture with no flash; add a flash that is not synced and you get the posted result.

My suggestion is that you set your flash to its default settings; do not adjust anything on the flash unit itself. If it has an auto setting, use that. You need to start at neutral, and then work from there.

As for the camera, use either shutter or aperture priority, that way you let the camera do the math. I personally like shutter priority.

Set your camera on a tripod if you have one, or on a stack of books, table, etc.

We are setting up a control test. Get something to take a photo of, like a stuffed teddy bear, probably not your cat ;)

Now you have something to get consistent results from.

  1. Picture of subject in either aperture or shutter priority, flash removed.
  2. Same subject, same settings, flash attached.

The key is not changing any settings.

What are the results?

Are the settings (ISO aperture, shutter) changing when you add the flash? You may need to engage the shutter release button partially for the camera to re-meter with the attached flash.

If your camera is not evaluating with the flash head, then it could be:

  1. You have told your camera to ignore the flash and the flash is operating as if pre-programmed, and in turn is ignoring what the camera is saying to it.

  2. Your flash sync setting is incorrect. Some cameras allow you to do what is called a slow sync, where the flash fires at the very last second before the shutter closes, you would usually get a black line across the bottom of the photo in this case. Or it is fast synced, where it fires way to soon. But I am pretty sure this is not your issue, yours is exposure.

  3. So third, it is that the camera is trying to use your flash as fill, but the flash is doing its own thing, and firing to a preset configuration.

I would look for something in your camera settings that contain the word "fill" in reference to the flash.

If you can tell your camera to use the flash as a "fill" or something to that effect.

Try to only use the flash exposure compensation as a last resort. +- 1/3, 2/3 etc.

Is either the camera or the flash significantly older then the other? You may have communication issues, I worked like this for a while.

If so just know where your flash is at, and be very familiar with it, if you get an under/over exposed, I would change the setting on the flash itself and let the camera meter on its own, you can get some great results this way.

Use the camera to control the ambient light and the flash to control the subject matter, think of them like dimmer switches in a bedroom: shutter speed goes up, lights go down, shutter speed goes down lights come up! :) Then you would use your flash settings to control how illuminated your subject matter is. God Bless.

  • Or it could be a manual only flash that does not communicate with the camera at all.
