The camera cannot be power up after power off for some time.
It may be the ESD (electrostatic discharge voltage) affected the unit. You need to open the
battery door and then close it after say 5s. Note that the internal SDRAM memory will be
cleared. So you should use the CF card for important photos to be stored.
It cannot fire the flash when I use it in my home.
The camera will measure the light intensity of the whole area of the photo. If it is higher than
the preset value, it will not fire the flash strobe. This can save power and make the image
color better. So it will not fire if the environment is bright enough (eg. Your home with windows
open and light is coming in). However, please hold the camera firmly. The shutter speed is
as low as 1/10 second.
I found some of the photos with the object too dark.
Take care of the background light intensity. It will affect the exposure of the main object. The
camera can calculate the total light intensity of the picture to fine adjust the exposure. If the
background is too dark, the object will be too bright. If the background is too bright, the object
will then be too dark. Change the position of you so that the object and the background are
in the similar light intensity.
I tried to take photos in outdoor, but some of them with the object too dark.
Even you take photos outdoor, you should not let the object under the shadow. The object
is not shined by the sun means for staying in the dark. The result is unclear object and bright
background.
Can I take a photo of the Sun?
Do not point to a strong light source such as the Sun. It may damage the CMOS image sensor
inside the camera. The background will be too dark and you see nothing in the photo.
The color of the image is somehow changed when I take photos indoor.
It will affect the color if the light source is the light bulbs. It is better for you to take photos
with daylight bulbs or fluorescent lamps.
How to use the viewfinder to get a good image?
Keep the viewfinder horizontal to get correct view of image. Try to kneel down if possible.
Can I take a photo in a short distance?
Do not take a photo with the object distance too close. It becomes out of focus if it is shorter
than 1m (3 feet).
I get some photos with black dots or too bright.
When you take a photo in a brighter environment and then take another photo in a darker
environment, it will not get correct exposure. Try to wait several seconds before pressing
the shutter.
Can I use it when it is raining?
Do not use it when it is raining or it is easy to get water drops. This camera is not protected
from water.
