The night sky is a jvc bn-vf823 charger
beautiful picture scroll. When I look at the stars in the night sky
compose full, filled with fear. I want to know how the universe, heaven
exactly how many stars, they are far from us. Capture the heaven of the
stars screen is a very difficult thing, but hope that this technique can
A, ready to work
you need to find the right conditions to find a suitable place, thus
increasing shooting photos of opportunities. Generally live in
prosperous, light pollution in the city of the basically see compose
full of stars the night sky.jvc bn-vf823u charger
You need to go to a remote place, away from the light pollution. Choose
a clear night also will be helpful. Prior to check the weather
forecast, you definitely don't want to be thick clouds of the sky light.
In the long time exposure processes, ensure that camera JVC BN-V514U Charger
is still is important, therefore you must use a stable on a tripod. In
order to avoid exposure period in touch cameras, a piece of the shutter
release is also useful. Any small tremor will affect the effect of
exposure. When you begin to press the shutter, a skill is a dark thick
cardboard cover on camera, once the camera stable, and put it out
Second, clear pictures
the earth in the rotation, photographed a clear sky photo is difficult,
unless you have a professional telescope in equipment. In no apparent
vibrant cases, the longest time to limit exposure in 15 seconds. To take
to clear the jvc bn-vf714u charger
screen, you need to choose a clear night. Choose as far as possible big
aperture, such as f / 2.8, and the shutter speed setting in 15 to 20
seconds between. You'll also need to set up GanGuangDu, out of control
pixels purpose, ISO100 or 200 more ideal; But you may be in order to
accurately exposure and will have to GanGuangDu revalued.
Three, star trail
stars must first understand is that the earth in turn, this means that
when you finish after point, the stars will move. This is called the
"star trail" effect, as you see in case diagram of such. In order to
capture the jvc gr-d796 charger
star trail screen, will the set to the largest aperture as far as
possible, from the f / 1.8 to f / 4, and put the focus Settings to
infinity, and then the camera at the pole star-north star will remain at
rest, and of other stars will be turning around it.
same, also need to set up GanGuangDu. When to start GanGuangDu ISO100.
In order to improve the exposure, sometimes you need to pixels
concessions. The exposure time according to the moon cast down changes
of the light. If is the new moon,jvc gr-d370u charger
the exposure time roughly 1 hour; For half moon, will control the
exposure time of 20 minutes. This is the attempt to use available light.
But remember, the longer the time exposure, the existence of a star
trail and also more long.
that bring some basic items, it will make you the whole shooting more
smooth. First of all, a flashlight will help you set up cameras, find a
tripod to provide convenient place flat. Just don't press shutter in
your time to let it on. Second, if long time to shoot, take a piece or
two spare batteries. Again, in not touch the camera's jvc gr-hd1 charger
case, can use a stopwatch to view or timer exposure time. Finally, if
you feel tired or tired, a chair or bench is quite useful.
Five, go out at night to practice
Shooting stars is a very energetic, especially for a jvc gz-mg21u charger
exposure need to wait for a long time. But, when you made to want
pictures, that it's very worthwhile. You can also go out at night in
filming the moon. This is a very good opportunity to practice exercises,
can help you live learn some basic principles.
With the naked eye the starry sky camera jvc gz-mg20u charger
see picture of the night sky is difficult, but once you've learned some
basic exposure setting skills, you will feel that is not so difficult.
You need to do is to practice, use of composition, looking for the right
conditions. In a two attempted after, you will make good photos.
Lens is by jvc bn-v20u battery
group composed of optical lenses, light through the lens can cause the
distortion of the image. Here we'll tell you about lens distortion of
Appear lens distortion, isn't about our camera quality is bad?
It is not. Due to the limitation of the focal length and lens
structure, all the lens can be adjusted one hundred percent reduction of
the jvc bn-v712u battery
objects. All camera factory in lube optical glass and coating materials
and keep improving on the structure, striving to lens distortion to a
minimum, but all lens will have some degree of distortion.
Then I spent more money, can buy less distortion lens?
Cost and quality may not become direct ratio, lens distortion mostly
depends on the structure and types. Price has some effect, but more
important is the focal length of the lens. Such as wide Angle lens,jvc bn-v812u battery
can appear the bucket distortion, this is because the optical
properties of the wide Angle of the decision. Each focal length has
different distortion effect. And zoom range, the greater the lens
distortion of would also more serious.
I never think of my lens with distortion problem.
We in the browse photos, generally not too concerned about this. And the design of the lens are jvc bn-v400b battery
improving, film camera lens through a long time development, have
become increasingly perfect, and now, digital camera photographic
imaging of components of the principle and the film is different, the
structure of the lens and coating and so on all need to be redesigned.
Advanced digital camera and photographic component design specifically
for the lens, can be reduced to the minimum lens distortion.
So now the lens of the production already perfect?
Now a lot of high-end camera has very good, but also of less than
perfect. Some distortion still can't avoid, such as lens dark corner. In
the beginning of photography, photographer was beset by dark corner,
until now, we are not completely solve the problem. When we in the JVC BN-VF815 Battery
computer through photos, can find pictures than the middle part of the
edge of dark (some would in Photoshop deliberately aggravating dark
corner, to add photos atmosphere). Now we can only through the camera
setting, and within the computer software to eliminate dark corner.
How many kinds of optical distortion?
Optical distortion of the sort very much. Such as dispersion, color
and sharpness low and so on, but of which only two or three deserves
That first about the most common lens distortion type it.
The most common distortion is curve distortion, of which the most
obvious bucket distortion, and easy to be perceived. When you use a wide
Angle lens, and find the edge of the object has a photo to the JVC BN-VF823U Battery
expansion of the deformation, and the most sublime is fisheye lens. The
general wide Angle lens will through the lens of the group structure
design, to reduce the distortion, and fisheye lens is in order to show
the distortion, create the naked eye cannot see picture.
Some lenses mean to show the bucket distortion, to create strong
visual impact in your photos, such as fisheye lens, it distorted and
clairvoyant feeling play on top of the world.JVC Camcorder Battery

because the object itself can glance, either because the object surface
can reflect light. Most objects are able to to reflect light, the
reflection of the light, the more he seemed more bright object. If the
object is completely black, it is not reflected a little light, that is,
its reflectance is zero. Another kind of extreme case is object is the
whole white, it will reflect all of the light, that is, it has 100% of
the reflection. The above two kinds of circumstances is the theory of
