Looking for Answers about Nikon Inc. COOLPIX S30?

Unfortunately, the flash cannot be forced on. To make matters worse, the implemented auto flash algorithm is seriously flawed. Even in very dark rooms, the flash will typically not fire. I'm not sure what kind of light sensor the camera uses, but I suspect it picks up on infrared or ultraviolet, cause it sure ain't visible light. (see attached picture from under my desk (low light), took a series of 6, all looked like this except 1 where the flash accidentally(?) fired.)
The flash is at best unpredictable, but in my experience useless. What a shame, this could have been a good camera, but bad software got in the way.
My advice, stay clear until a version with manual flash control is available.
(To Nikon SW developers: it can't be that hard to implement?
To Nikon product development testers: How did this one slip through?)

Usually in the menu, or a button outside will allow...off, red eye, auto, on...for the flash, look for a lightning bolt symbol...should also tell you in the manual for the camera.

Here are specs for flash on this camera, found in "tech specs", below picture of camera on this site...

Built-in flash Range (approx.) (ISO sensitivity: Auto) [W]: 0.3 to 3.5m (1ft. to 11ft.)
[T]: 0.5 to 2.0m (1ft 8 in. to 6 ft 7 in.)

Built-in Flash Control TTL auto flash with monitor preflashes

Hope this helps...

I would suggest contacting "Support" here in this section...

Best to contact the manufacturer of the cards...Lexar, SanDisk, Kingston, etc...

Cnet review says 3.8 seconds startup and 3.3 seconds between pictures.

When shooting with decorate/Frame around your image, the image resolution is fixed at 2 megapixel and cannot be change. Large(10megapixels) and Medium(4megapixel) will be greyed out.
