Infoseite // XH A1 High Definition: Violent Noise despite presets

Frage von MatthiasXH:


Canon supplies all our pictures from extremely noisy, woodchip wallpaper, you can hardly look at.

The last test recording we did in a studio with two 300W lights was illuminated. Poor or low light conditions were not the problem.

I have the presets from Wolfgang's HD video and have never experimented with all three. At-3dB preset the noise is as strong as in the work setting, at +6 dB, it is much less strong. Similarly, at +12 dB, but because everything seems very washed out.

ND filter was always set to "Off", the gain switch to L, White Balance manual and once again tested car (preset to K).

What can still have an impact on the noise? I had the camera for all shots at 1 / 60 and an aperture of F2.6 asked - is it so together, perhaps?

This one more question for Shutter: Inadequate expertise in the area I used the setting as the shutter of a DSLR. As for the brightness that worked very well until now synonymous - perhaps it has now made it with the noise to do.

I have learned that under optimal conditions, a shutter speed of 1 / 60, a rule of thumb when it comes to photography and still without a tripod to avoid blurring. For shorter times, it is then already "exhausting" not to shake. What about because with the shutter at the XH A1s? Is there a guideline synonymous, s.wann about blurring the Picture?

Of course it depends on what you have in front of the lens, maybe the answer to this question is not really clear;)

PS: Manual White Balance can but have no effect on the noise, right?

Thanks and Greetings
Matthias

AGC switch to "OFF" been? AWB to "ON"?

Otherwise leaves rustled in the woods .... see:

Antwort von MatthiasXH:

Jap, AGC switch is off, as described by Wolfgang. This morning I tried it a lot. Again, the presets and each set of Wolfgang to-3dB, +6 and +12 dB gain switch synonymous to each set to -3, +6 and +12 dB.

Even a high shutter speed with a small aperture and vice versa does not matter.

A change of 50i also applied to 25F - which I would be synonymous been a mystery - no difference.

The link I meant with "Wolfgang's blog." These settings I have so used.

Hello

1) if you do not know what or why one should want to change the shutter /: Hands off! it is in principle not necessary for normal shots there to change something .... photograph is not the same video shoot .... particularly in relation to the exposure time .... When shooting comes as the change of exposure time is not the primacy of photograph as in the

2) the work of Wolfgang presets very good - if you follow his instructions exactly .... have you ever been to the position of the AGC switch you seen? could think of who is still ON .... Vice him to OFF if you are working with the presets, or do not work properly this

3) s.besten the reset cam precaution to factory settings, again wolfgangs checklist to go through for its presets (eg AWB and AGC = OFF = ON .... and the gain-switch s.der corresponding point preset with corresponding ... . So "L" at -3 or "M" at +6 ect and "H" at +12) .... synonymous then the results should be correspondingly

hope I forget nothing :-))

... and there already someone was faster :-)

Antwort von MatthiasXH:

Hi Rob,

exactly how I did it, is synonymous AGC OFF. At +6 dB gain with preset to M (+6 dB are synonymous set there), I have very reduced noise in my indoor shots.

However, today is synonymous extremely gray day and the light of halogen lamps 5-6 very yellowish.

It may well be that the XH comes from these conditions s.ihre limits? see, when on location in the sunshine all be back for quite different.

PS: My knowledge of the shutter is limited to motion blur. If I want to record a football game, I set a shorter exposure time. Otherwise, I let them synonymous not put your fingers. If the light is so weak that the aperture is already set to an extremely large but the picture is still too dark (synonymous with +12 gain), then I would go first s.die exposure time.

But one question I have yet:) When you say: hands off - you can give me a tip for a "default" type for the exposure time, which I never let any better?

Thanks for your help!

provide for optimum motion reproduction shutter to 1 / 50 (with faster times affect the movements choppy like), Aperture is not possible, choose less than 5.6 (not 8 or even 9.5) otherwise the picture visible matschiger.Auch with open Aperture (small number, about 2.8 or 4) You will get good results ... Vote with ND filter, the exposure (that is all for the manual mode!) but with your problem (noise) do not help much.
You compare this shoot with pictures.

So here comes the Cam certainly not s.ihre limits :-))



Antwort von robl21f:

hello ..... leave it in the standard setting (1 / 25) .... the with the motion blur I know of course synonymous (synonymous photograph so incidentally), but when you shoot s.ende a still image, but when filming a moving image - and acts as the "motion blur" on the eye was different from the picture .... your idea is of course well-intentioned, the most effective but very different ....

if you are a single film frame (a single one of 25/sek) of a fast motion look at this then let evt (motion) blurred his .... are you looking at you but the frame in the entire / (film) movement s.so it's sharp and substantially sharper than individually

So there really nothing you need to adjust .... I've never seen the necessity / need to change the shutter .... it may be extremely evt situations, they are but I had not been and I have both hill climb for example filmed (fast motion) cabarets as synonymous poorly lit

I put in my regular picture with aperture (mode dial to "M") and the presets on the corresponding light-effect relationships / one .... the skin synonymous out just fine .... and at +12 then it must already be damned dark ... I've so far only 2 - 3 times needed .... even in the Walpurgis Night and a fire show were the only + 6 ... and great great shots

Greetings rob



Antwort von MatthiasXH:

Hello filmography,

Thanks, I have loaded the preferences again and reset the presets (and checked 3 times;).

Shutter is now synonymous 1 / 50. The benchmark with forks 5.6 is good, I will remember me, then I grab prefer to ND filter to decrease as the Aperture or next.

And yes, I will stay only in manual mode;)

Thank you schonmal for your help, I'm going to wait for better weather and then test some new recordings. I am curious how are the recordings!



Antwort von robl21f:

toi toi toi well then .... And remember: it makes synonymous in bad light even good shots ;-)))






Antwort von nicecam:

|||-: If they would rush MatthiasXH not only for. It roars after all, right?

For correct exposure see again this informative thread: Aperture - Shutter limits and optimal settings?

To Noise: You do not have to wait for better weather, light and take the-3db preset. It roars? Violently? Then what is true but not s.den of you made the camera settings or is defective. Loading photos or better yet maybe a video, then you can judge better.

Now you write "violent noise". Obviously, should any noise but camera, even at 0 or-3dB. Just not violent.

These interesting questions will be discussed in the following two threads:
[List] Gain 3db
Ruessel presets [/ list: u: 8002119ffb]



Antwort von Filmo:

The words may seem unnecessary, but better safe than sorry:

It is obviously not enough to save the preset in the action, you have to conjure it synonymous to the custom keys, you should be of the chosen name for the preset are then read during the recording on the display .......: -))

Another note regarding Shutter 1 / 50: the best indication of the accuracy of the shutter speed for natural motion gives you the shooting of running water, just 1 / 100 sec shows as a strange picture ....
