So, I finally figured out (with your help) how to find BULB in M. But, is it normal to press the ml-l3 button three times to get a picture. I did turn long exp nr to the on position. and the release in...

You should only have to press the button twice to take a picture. In the BULB setting, the first press opens the shutter and the second press closes the shutter. With the long exposure NR turned on, it doubles the picture taking time. If you take a one-minute exposure, for example, the remote will be ignored for a minute after the second press.

Try turning off the long exposure NR just to see whether two presses do the job. If it doesn't, please feel free to reply to this post and provide any additional information you can.

My Samsung L100 Camera doesn't know how to flash once!

Most cameras flash twice; the first one is for setting the exposure, the second one is for real. About the best you can do is warn your targets that the camera is going to flash twice.

Yes, the L100 has a self-timer. Press Right on the selector (the clock icon) until the desired mode indicator appears on the display. Your choices are 10-second delay, 2-second delay, double self-timer, and motion timer.

The self-timer is described on pages 29-30 in my copy of the manual.

I want to take pictures of The Northern Lights. What setting?

Correct, you don't want the flash.

Some cameras have a fireworks mode, Unfortunately, the SD400 doesn't. As far as I can tell, the SD400 doesn't even have a landscape mode, which would have been my second choice.

I'd start by turning off the flash in Auto mode. Unfortunately, the camera is going to try to make the night sky a medium gray. You'll have to reduce the exposure using the exposure compensation feature. Review your pictures and examine the histograms to fine-tune the exposure.

My other approach would be to use the manual mode, reviewing the images and histograms.

Either way, take lots of pictures. Feel free to experiment with various exposures. Remember, there is no "magic bullet." Your sky isn't going to look the same as mine, so my settings won't necessarily do you any good.

Forget how to take double pictures.

Hey xplaur,
To take a multiexposure photograph you should first expose the film, and then push the multiexposure button which is on the front of the camera on the top left when you are looking at the front of the camera. After you press this button advance the winding lever to set the shutter, and since the multiexposure button was pressed this shouldn't wind the film to the next frame. Now take your second exposure, and if you want to make another exposure on the same frame repeat the process. Keep in mind that every time you expose a single frame after the initial exposure you will be doubling the exposure on the frame. I usually under expose each exposure by one third on a double exposed frame. If you do more than two exposures I would underexpose each exposure by even more. Multi exposures are fun but tricky, and I would suggest you experiment and have fun with it. I will also say that black and white film is much more controllable and forgiving when it comes to this than color film. I hope this helps!

Go Ahead. Use Us.

Synchronization problem

Set camera to Manual modes
Set Shutter to 60
Set Aperture to 5.6
Set ISO 400
Set lens at 10 feet
Subject at 10 feet

Turn on flash and wait until fully ready and do the following:
Set subject dead center, shoot with flash
Set subject to the right, " " "
Set subject to the left, " " "

Only the subject in center should have correct exposure.

Hope they are helpful.

Photos are too bright, almost white....

camera makers would like to use flash lights as bright as the sun, so the flash is fine. the problem lies in the exposure time. continue trying different exposure settings. most makers provide these as pre-programmed settings while some offer manual fine tuning.

DMC-FZ10 and an external flash with a manual trigger can do it. Just set a high aperture number, slow shutter speed, take the pictures...change camera direction a little..then as soon as you can, re-trigger the flash manually.
