Frage von besucher2007:
Hello,
what do you have the aperture.
Only around for a low aperture value to obtain depth blur?
When should I adjust the Aperture manual and why?
Drug interactions affecting the colors better, but it comes uszu or more image noise?
Antwort von Andreas_Kiel:
The Aperture is the video for "Number 1", when it comes to a correct "exposure" of the band goes. The opening of the Aperture controls the depth of field: the next to the smaller.
Other control options for exposure are Graufilter (reduce the amount of light and force to next aperture = small depth of focus), shutter-speed (leading to values longer than 1 / 25 or shorter than 1 / 50 to be modified motion presentation) and gain (electronic amplification of the image ).
With the noise, the aperture
is not directly to do. The noise starts - depending on chip size and quality - with decreasing light conditions. An otherwise properly exposed can vary depending on the recording camera model include noise or not.
Those who must work with gain, because the light is short, the noise is increased (this is synonymous is mitverstärkt) in Purchase.
An automatic shutter, the exposure to an average of the total image. You may not know what your points for picture composition are important. Because of the limited contrast range of video material (much less than negative film), it may happen that important building lots "burn out" or "absaufen", ie, in the bright or dark points is no longer recognizable drawing.
At high contrast image is therefore the Aperture manual to ensure the building important places to expose correctly. Professionals avoid such contrasts as controlled by illumination.
A manual adjusted synonymous Aperture has the advantage that changes in lighting the picture does not begin to "pump", because the automatic dagegenregelt. The best example is the guy in the white shirt, all at once into the picture goes ...

The Aperture regulates mainly based on the recording surface incoming quantity s.Licht.
Aperture - dark
Aperture to - lighter
I compare this now with the principle of a curtain ...
Effects such as the depth blur result from other phenomena of the Aperture ...
These recommend the Wikipedia - article or the Google - Search.
Antwort von WoWu:
The Aperture is synonymous but also one of the most dangerous tools. The aperture effect makes the images blurred and at a pixel pitch of 2ym or even less has been devoted almost exclusively to one or two panels with which the picture shows its true sharpness (Aperture beneficial) then roars the Picture s.in the blur.

One question that arises for me. Is it better to fix the aperture or the shutter? Moreover, if I have my LCD on the camera can see the picture I always have the problem that it is somewhat lighter than later in the post (or halt reality). Aperture The fix may be to have just in unique situations to lead to dark images. How can I prevent that?

@ Present
With the shutter again to get other effects that are significantly worse than slightly too dark images.
Experiment with the ND in the area of your supportive Aperture to come. White Balance before without ND.
Against the brightness difference helps to monitor the brightness of the camera to adapt. A few attempts and you have the optimal setting.

Hello Wolfgang,
I drive my display s.der the HV10 and HV20 in the dark area, so controllers in the menu at almost zero and there is still much brighter than later s.Calculator. Somehow, the background illumination of very bright Handhelds
Mal 'ne stupid question: ND?

Antwort von WoWu:
Hello Axel ..
ND's are Graufilter that's before you and the Lens screw you, depending on thickness, 2 or 3 Apertures take.
Do you have relationship with the camera-monitor times experimenting? Whether it really is s.der Camera?
Apart from this, perhaps the hab'ich misunderstood something, but if you get the monitor dark s.der Camera post, it must be brighter later.
You must make it brighter, so you take it down exposure.
Imagine, you do the Cam-Mo travels quite dark and the Aperture on, just to have something to see ... what do you like the looks afterwards.
So, just in case that is not something I have misunderstood: Monitor light exposure and down ... and a few compare with the external monitor, or output the same s.den ext. Mon connected and the Cam-Mo then parallel set.
Then the work synonymous.

Hello Wolfgang,
I voted for both the Canon wide-angle cameras on it and yes, unfortunately they have no filter thread for more. I am still looking for a possibly Aufsteckmoeglicheit for polarizer and Co but until not so long really successful. Synonymous needed for both Lenshood but the tulip is here in USA is not as widespread :-)
As to the screen: The camera displays are brighter than the picture later on my VorschauLCD, which means NVideaTool set. I've noticed that most of television in my area still have a touch darker and thus I am with the darker LCD quite close. For outdoor shots it all fits pretty well, just stop in a little dark rooms can be a problem then that is admitted to duster.

Hi,
rather than the brightness of the camcorder's display s.das TV image (which adjusts for inside and outside of it no more), would be synonymous gathering of experience into question.
I have in my camcorders times found that they were well s.der Color of skin can be based. Getting skin tones on the first LCD yellowish trends, then the aperture to wide open and needs to be a step.
This makes me synonymous with these questionable color LCDs safe shots taken so far succeeded. It should perhaps be mentioned that in the example above, only with higher quality Sony camcorder went. For other manufacturers and price ranges must not be the same.
