Frage von lofi:
There is a front s.der Camera White Balance sensor.
In all instructions is then for the manual white balance (MWB), that to the visible picture is completely white.
What in the White Balance sensor should be, is nowhere.
Background: Operation of the camera in an underwater housing.
Since getting the white balance sensor may be little light.
The MET is via the LANC interface
however, takes longer than if it directly on the touch screen is executed.
And the problem: The MET operates unreliable.
And I try to find out why.

What in the White Balance sensor should be, is nowhere. Perhaps the sensor is intended only for the automatic white balance?

Antwort von WoWu:
Serves on the sensor for the White Balance? Because that is usually on the image sensor made. It looks for the camera electronics, the brightest point of the image and assumes that it is acting white. From this area are now all the color removed from overweight to neutral in color so that is. This has obviously synonymous impact on the rest of the picture.
Therefore I do not know what the point in this context, a second sensor would.

Antwort von Alex_HH:
I think the sensor is just the automatic white balance and not the manual, as you vornimmst him.
Can I be wrong but synonymous.

That would mean that the extra sensor Farbmaske and synonymous with their own color management to work. Where else should he get his weight .... and why?
What is going on indicates that the sensor is used the White Balance?
Is there any info?

What in the White Balance sensor should be, is nowhere. In the instructions below http://static.tigerdirect.com/pdf/sony-HDRHC5-7-manual.pdf is nothing magical about this sensor. If it were such a lentil-like structure, could be an AF sensor be. If there is a red colored plate, then it is an IR light for the great SonyNightshot mode.

Antwort von Bernd E.:
... What is going on indicates that the sensor is used the White Balance? ... Is there any info ... The HC7's, I can not say, but I am referring to the entire D2 series of Nikon, this extra sensor on the front of the viewfinder prism had. Information can be found in any quantity, representing this quote:
"In the White Balance, the D2Hs as the D2X with three fair-systems: A s.Prisma sensor measures the color temperature of the ambient light, regardless of the object colors (light measurement) and thus influenced by the image sensor and of the 3D Farbmatrixmessung supplied values - synonymous in flash photography. " (Source: http://www.colorfoto.de/Testbericht/Nikon-D2x_568650.html)
Antwort von WoWu:
s.Prisma !!!!!!!
Sits outside the s.Gehäuse? Probably not.
Antwort von Bernd E.:
... Sits outside the s.Gehäuse? Probably not ... In the above Color Photo Link is a Still Image to see: The small white area FOREIGN s.Prisma D2 above the Nikon logo is the additional white balance sensor. Sitting somewhere inside it in the cabinet, he could not measure the ambient light.
Antwort von WoWu:
Well, it's drum in any case, I think the question is that the really relevant to the White has a balance, especially since it is merely a further, additional measurement act.
Perhaps one should really only be clarified, including the part s.der HC7 really is good, because this Deti not even a hint in the manual found.
Anyway, the white balance no history, primarily outside the signal path is taking place. (Also not with exotics), which may require additional information immediately. The white balance takes place synonymous with the signal instead.
Antwort von domain:
In my view, it overestimates the importance of manual white balance defined at all seriously (from automatic times to mention).
It is true, the AD-converters operate virtually at the 12-14 bit level and then the value has been selected and especially the automatic white balance, but actually rather dubious, because of unpredictable and flexible while sliding synonymous during the recording works , but the NLE interface with security is useless.
On one should always be aware that there is no real adaptation of sensors s.eine certain color.
All sensors of a certain type have the same properties and a possible adaptation s.eine certain color is always just about the only electronics instead.
Therefore, standardized adjustments rather the tool of choice, just as it is actually many years ago, time was when only the choice between daylight and tungsten film existed.
Nothing else is required, the rest will be compensated in the NLE.
Antwort von WoWu:
The sensors are not adapted anyway, because the sensor does not influence colors but the algorithms behind the Farbmasken make the interpolations in a direction influenced by the location of the white point in color space very well influence.
To find out more is actually not at all. But if the situation for the White Studio not true in most cases synonymous the NLE or color correction overwhelmed, because the whole spectrum is shifted to the conditions and situation of Weiss None Color agree more ... So White balance is not so unimportant heist and, above all, not only that Weiss Weiss is synonymous, but synonymous, that the other colors.
But as always, it is of course a matter of entitlement ...

I agree with you for 8 bit encoding totally agree. There must be no longer in the NLE to large corrections come.
But it is already often a mistake in artificial shares in the Picture and concurrent vote of daylight Cam on a correction in the NLE to want to implement, so usually does the typical atmosphere of the warm light flutes, especially for evening moods and sunsets in nature.
But if there is only artificial, then select the predefined stop my default setting for the artificial.
The only exception in my view would be a typical ev (often green) fluorescent tube situation, but mostly wrong, and so if it is not a special photo lamps act.
Antwort von lofi:
Yeah, I think I am with my Pana GS500 confused.
But my problem may well explain None?
I think that is a white card in front of the building fills Camera
and do about LANC (on the electronics of the Silverfish-Unterasser chassis) from something, like what irgendsowas
White makes a balance. These changes
in several jumps the brightness of the 3 primary colors
of darkness after Hell, until then, at best, after a few seconds
Picture appears stable. Klappt do not blink
the WB symbol as described in the instructions.
This happens in my experience when it
too dark or red is too low (lower than 15 meters).
The manual Weißagleich on the touch screen (button "Skip")
I can not use it. En manual white balance on this
Tuchscreen button is much faster than on the LANC.
If I use the material then in Vegas with the tool "RGB Parade" chart, I see that the red cloud pixels for example, to commute the 64
Green and Blue is much higher, sometimes synonymous only green much higher.
Sometimes the Rotschweif synonymous begins at 16.
Then I subsequently lift the Rotwerte s.oder / and the lower green portion from. But the small-scale dynamics of the red course, so I can not repair. Somehow, the result from then muddy.
Antwort von WideScreen:
It may be synonymous under extreme conditions to come, then that color by the White Balance "overridden". Red for example will disappear very quickly and then when the camera will adjust white, "pulls" the Rotverstärkung fully, and if not then the emergence nachkorrigiert can cause strange effects.
Light is the magic word when diving, then klappts synonymous with the White Balance.
Antwort von lofi:
Looks like. More light in a larger Obektiv on larger chips.
Since I am probably not drumrum.
Antwort von WideScreen:
I thought that rather s.künstliches light. Entstehdend by extreme heat. Say UW light. The Picture is only illustrative serve. Gibts ja special Funzeln for video.
Antwort von domain:
I do not really lofi what you with a white balance under water ever want to do. I've already had some synonymous filmed under water and of course comes as only the standard daylight white balance in question. Especially the blue water effect is essential for a good picture, you will not be a gray in gray from want to be.
The red and yellow color in turn, can only with additional underwater lamps be reached for a white balance, but certainly would be impossible.
Antwort von lofi:
... for a white balance, but certainly would be impossible. There are the shooting with and without lights.
Halogen lamps have a very warm light.
I wish these two situations are not the automatic white balance left. I had times at night the situation,
that two different lamps have illuminated the scene.
Since the automatic white balance in the 2 Hz beat between
two terrible wrong and her attitudes towards gependelt.
Critically, it is naturally in mixed light.
Since then HID / LED lamps of some preferred.
But for the shooting alternately with and without light, I need just the manual white balance. Why is he in the Cam-Control for Enclosures> 1500 ¬ installed?
The problem is probably that good UW-recordings without additional light
with 1-chip consumer cameras are difficult to achieve. Except in the shallow waters of the tropics has been constantly with Lowlight a situation to fight.
But if someone regarding White Balance with the HC7 housing Silverfish
still has a tip: I like to learn.
Antwort von WideScreen:
I make the White Balance synonymous, because the changes with increasing depth. From 20-30 meters but remains almost constant. Light, map it, WB press ready. Where is the problem? However, one sees little difference to the automatic adjustment. And since "down there" little white things are true, this is not synonymous soooooo important. Important would be to go diving when the head to break, as it could go. You're not just once into the water. Try ie.
