Frage von hoschie:
From the site moderators, I have unfortunately received no reply, so I tried it a try here.
I have a test procedure, a brief question and hope someone can answer me this.
It is about the "luminance resolution" test pattern. In the Appendix I have added two sample images.
Can you please explain briefly what I can see a better camera, or what does the second picture
the limit at around 80% where the red line is below the 0.3 line of contrast?
Thanks in advance
Sincerely,
Chris

Counter-question: are actually two posts for two trivial questions necessary? The charts are still clear!

Antwort von hoschie:
The two responses of Deti and Bernd Unfortunately I can only say that they are absolutely meaningless for a nonprofessional. If the statements were so easy, I would ask these questions here in the forum. The declarations of Slashcom are not for me to understand, therefore, the detailed demand.
Therefore continue the request for a qualified answer.
Thanks in advance

Antwort von Nathanjo:
I am also a non-professional, but some experience would recommend you do not break your head on the charts but to read the associated text to view pictures and test scores.
Whether in detail where a brightness resolution is higher, there a noise value below is for you or something completely irrelevant, because you will not notice. What do you want to know is whether a camera gives a better picture or the other, or whether suitable for your purposes.
If you flashy colors are important, make sure if you good lowlight shots are important to pay attention to relevant information and the lowlight test pattern.

That's just what Chris does not want to .... But what he most unfortunately only get test plates, enriched with some really "underground" charts.
I can easily see that he very much wants to understand the context ... others will not do, and where many colorful pictures. But Chris does not seem ... fortunately not.
But is it really so that you can see the complex relationships (; and needs to understand). Individual charts singled out not completely hold up, to judge a camera.
But if we consider (the entire complex; Camera), thus including Lens. Sensor (, s), processing and data reduction, a "shoe" come of it.
So the horse bridles of Page on the other.

@ WoWu
I understand that. However, I have the feeling that he is too little in the matter to anfzufangen synonymous only to understand what it's going. And I think that it's synonymous with what you mean singled out charts. Erstmal you need to know much about the background to see whether the test results are at all meaningful.
What I meant is not colorful pictures, but hard facts, not only in scientific diagrams and concepts that go into highly technical, but practical relevance. What is the lowlight behavior? "Strong noise, lack of sharpness, but the average in this price range. Sowas is to find meaningful and says someone who does not know what luminance resolution is already a lot. In practice, that is, after all relevant.
If you look at it of your Page erstmal he should begin to deal with the whole of the front matter and understand the technical and physical contexts. Certainly not wrong, but perhaps exaggerated - according to the claim.

Hello professionals,
My Choice is currently closer to a purchase the following models:
Panasonic HDC-HS300, HF20/HF200 Canon, Canon HF11, Canon HF10/100, HG20/21 Canon, Canon HFS10/100.
Can you give me a hint what would it be for as s.besten and why?

We are there quite a view. Only such a comparison does not yet give a long decision-making criteria.
Short example: low-light behave ... big issue for all who like to shoot in the dark. Setting on strengthening "zero" and then compare the result ..
Result: pretty useless, because the dynamics of a camera is always of the noise level up to the maximum level. Camera also has a low noise level, I can send it safely into the reinforcement, without compromising my picture on. Result: The camera would be for low Comparison of light (in a reinforcement, at a rate that is identical noise behavior).
Example 2: 8-bit or 10-bit Camera ... a 10-bit Camera has an SNR of -60 dB, an 8-bit only -48 dB. Reinforcement "NULL" So nothing heist .. therefore, such images can not synonymous, "Low-Light compare. Such tests are therefore quite per ton.
But I agree with you totally agree. If you anschafft the base, relativize such things to be synonymous, it is no longer strictly synonymous extended marketing activities.
@ Chris
When I look at the camera list, I find just one camera, which has 3 image sensors.
As I need hardly go into further detail, in order to provide the fact even with a thick pros too.
With the 3 chips (; and no Bayer mosaicking) do you manage at least the full resolution. Chipper get the one-way only with interpolation.
Otherwise one can, of course, still more than one or other advantage or disadvantage to entertain synonymous in handling or in the workflow, but such a fundamental criterion must be condemned even more to compensate with other extras.
You see, nothing with luma or chroma charts .... sometimes they are the basic things missing from the cameras already.
