But Claudio's speech is correct ...

1/1250 @ f/5.6 ISO 6400 = 1/20000 f / 4 @ ISO 51200

Gannjunior criticized my other tests because it was a 1/400 f / 4 ISO 51200, but in reality the other photo is in a state of light STOP FIVE AND A HALF weaker.

In essence, if we want to be faithful to this reasoning photos of the D4 would be the most "loyal" to the reality, not the other way around.

I hope I do not try to tell that the lens used determines the noise :-)

In fact, so this test as that of D4 are quite realistic. Obviously some test photos can not cover all situations in the world, but give an idea of ??the resa that you can have a certain sensitivity.


EXACT!! I tried to say it in every way!! Numbers in hand we can not say that this test is put in crisis the sensor more than the other, quite the opposite! Here, the sensor there was "really comfortable"!

Sorry, but x is not a test you could put the two bodies near framing the same subject with the same parameters, the same distance with the same goal, (like a 50 1.4 x both) then can compare everything.
certainly not easy to have two bodies cosi'disponibili.

Funny Max
A less to consider the movement of the object. You forgot this and I, looking at the kind of photos, I supposed.
But of course you do, be smart and this is undesirable.

Then, frankly, if the purpose is to try SYSTEMATICALLY the controversy, pretending to be proficient speakers, then, continue to have fun. But that alone.

MY constructive contribution you can find in MY willingness to test that can show whether or not what you do you insist on support without degnarti minimally correlate with tests or tests that prove the autenticià.

Give me a break ...
and learn to read Wolf3d ...

Your questions are provocative, and I have already responded with arguments scattered in various posts. I have to work, so I pay attention to how much time to spend on intervention rather than another.

Grannjunior look, I think what you want to do systematically controversy here is you and I think this is clear to everyone.
Then give me the question ... you wildlife photographers? no cause to stop a subject like this that swims in the water (so rather slowly) with a 300 and this distance could maybe even drop one stop times and ISO. So you'd have to shoot zero on this test, as you dotto see other people different from me, including Juza. Then if you want to take with me the go ahead.

looks Grannjunior, I think that what you want to do systematically controversy here is you and I think this is clear to all.

Everyone reads and everyone can judge and watching all the messages around, what is the approach to MY forum and what is YOUR.
And I'm afraid you may be disappointed about your alleged statement of truth.

Ema,
I thought the answer was clear from what I wrote a few msg ago. In this shot I assumed the movement . Even in the same light, means introducing a variable more than another shot where you were probably also rests on the table with his elbows, even when it comes to limited movement and predictable (for the bird). Then I considered the weight of the equipment and you've taken freehand. That's why I felt (and ritengo) this shot more realistic than the other. In any case, I agree that you could get the same shot even at lower ISO.
Cmq And this was my impression and, unlike other interventions, there was neither the first (and even less now) the intent to argue for the sake of bother. ;-)

Imara reading this Gannjunior ...


Even if you're not the only one to argue that the amount of light can affect the yield at various iso, I'd like you to take me now the arguments that you said you have scattered here and there to support this outlandish claim.
The color of light affect the cause're ready to shoot, but I hope you understand that why ...

I want to clarify what I said before: the amount of light she can also affect the quality of a shot because if forced to use very long exposure times these may lead to overheating of the sensor and thus to the appearance of thermal noise, which in conditions of greater luminous intensity, and therefore with lower shutter speeds, would not be present.
When you click in the city, using the light of the street lamps, or taken by candlelight will be taken to correct the temperature of the shot, which would appear reddish. To do this you go to overexpose the blue channel, being that lacks information will pop up that annoying grain of which you speak.
Bye

This assumption is not entirely wrong, what is wrong is the second estremizzarla: a big difference in luminance (ie noon vs. late evening) really creates a different yield, instead comparing situations where the difference is not so huge there are no significant changes in the noise (provided of course you compare two identical shots with histogram).

What we do strongly influences the noise is the key of the subject (light subjects show much less noise dark subjects) and exposure (an underexposed picture is much louder than a well exposed)

But I think not. Having said that I will not pollute this topic, realize that I'm not the only person who refutes your assumptions, maybe I'm the only one who continues to argue. For realizing just rileggerti this topic from the beginning.

Although this may be true, but that's not all, the situation is complex whereas each sensor affects the different tonal areas in a different way. If you go to comb through studies on sensors that DxO did you understand what I mean. It 'a collection of things, including what you said. Many vary from situation to situation, other systematic are the type of sensor.

Nikon has always had more incision in the shadow / dark colors than Canon, capturing more detail and here is pHY if you retrieve underexposed photos with Nikon get, in general, photos cleaner (you can find on the net tons of evidence). But even here there is an added value to Nikon, you just have to learn how to properly expose Depending on the sensor you are using.

If we take with lights very low, raising the ISO, the signal amplifier goes for strength to "pull up" the noise existing in areas of shadow / dark tones with a consequent deterioration in the quality of the file.

ALSO I found confirmation of this in the 5D III compared to the D800 worsens exponentially as you approach the ambient light in the dark. Then to notice appreciable differences must really get to have little in low light.

But then again it's all a matter of learning to exhibit the characteristics of the secondsensor.

However, the conclusion is that this is true:
a big difference in luminance (ie noon vs. late evening) really creates a different yield, instead of comparing situations where the difference is not so huge there are no significant changes in the noise (provided of course, to compare two shots with the same histogram).


Add in some machines the noise is emphasized more than others.

Wolf,
I can not see the attachment side of the job is locked.

Max,
honestly, but I ask you with peace of mind, but do you realize what you've written? The speech is interesting but wandering . Discourse light is vast and there are conditions of light in which our machines are "worth" to ISO 100 ... (and I'm not referring to the long exp than 1 ") ...
Then mention the recovery nikon shadows? but that has to do now? when I talk to? when? pls Max., but do you realize? I am also one of those who has always praised (in 3d and other topics in relation to your digression) and has never been fully convinced of the recovery canon shadows .... I do not consider really the point of all this and yet ....
If we take very low light with raising the ISO, the signal amplifier is to fluffs to "pull up" the noise existing in areas of shadow / dark tones resulting in deterioration in the quality of the file.
well, true, I confirm. So what? what to do with my alleged assumptions ...


Ema
What we do strongly influences the noise is the key of the subject (light subjects show much less noise dark subjects) and exposure (an underexposed picture is much louder than a well exposed)

true but that no one has ever questioned and on other occasions I have spoken ...

Max, you could not do yourself any evidence?
The results of DxO do not speak perhaps even how it is run the file from the software (it's on camera or not) going to interpret them?
You will know that it is enough to change style pictur to get more dynamic range, more recovery in the highlights or blacks, etc. ...
This may depend on the results of several different camera bodies, by virtue of running in a different way the information stored by the sensor.
I know that is not all there, or what they would be doing all the talk about technology photosite, their size, the bit converter A7D etc. ...
But if you are aware of any test like I did (16.5 stop difference) but coming to different conclusions set me the link please! Or even you do some testing, nit takes on anything! I think it's important because it's more or less what we are talking about for days now.
The first test told me that the stop of difference were too few (5 I think) are now 16.5! : D
Then I do not understand when it comes to sensors in the words affects the different tonal values ??(?), This sensor returns warmer colors of another, etc. ...
A sensor does not affect anything, do not return anything, the sensors are stupid, are a set of sensors that measure the amount of light radiation that hits them and they return from the electrical values. A colored matrix then ... blah blah blah
On my side, as well as self-tests will try other network information.
Hello!

I like this your last trip ... you could copy paste by opening a dedicated 3d?
first, because it makes no sense to continue here, second because it is really interesting and you know that between theory and practice there are many challenges as well as our machines are crap if you disable noise reduction color (a pet peeve, especially canon x) and everyway I think the speech sw in the room and PP is the key to everything even xkè I was stupid of certain results at high iso from my om-d ... yet the M43 should "do shit" at high iso according to what has always been said about the sensors ... but ...
in short, a dedicated 3d does not "lose" in here ..

Azz I was wrong to rely, 11.5 stops of difference between 1/500mo to 6 ", I do not know what was going through my head: S
are, however, several, if you think that the light in the second situation was almost the tremilesima part of the first (2 ^ 11.5).
Practically shooting at ISO 100 in bright conditions but exposing to 6 "in the dark as the photo would be overexposed by as much 4-stop!
The chromatic noise affects nearly always red and blue channels, because they are those who go further attempts to replicate the missing information in the matrix, while the green channel is almost always clean and detailed, because he has dedicated 50% of the sensor.
That's why (tralaltrecose) in astrophotography using CCD sensors without matrix.
Then if you put the lights in our homes or townsare almost always hot see that the blue channel is always a ciofeca, especially when you try to make pp white monitor something that was not white.
See for example the blue channel of the test photos of the big book posted by Juza these days, is practically non-existent.
And it is amazing to see how it is recovered in the first step processed.
You can do it yourself by duplicating the original shot, sfuocarlo for about ten pixels in color mode and merge with the layer below. You will see the red and blue channels reborn.
Of course you lose the color information, especially on the furniture.
Gann, open yourself thread :)
