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 "chroma resolution" test pattern. Below I've included two samples of images.
Can you please explain briefly what I can see a better camera, because these test images
Unfortunately, the statement on your home page is missing. (; At least I have found none)
Thanks in advance
Sincerely,
Chris

That's almost as if you were two auto-stand Logos and ask what is the better car.
Question You'll have to clarify it.
But when I look at the MTF in the second example, look at .. (; provided that the MTF curve is to be what emerges from the chart is synonymous not so ..) then the choice is synonymous with no other criteria is not difficult.

the charts are from the Slashcam-test series. It has been deliberately omitted to attach the Cambezeichnung.
If I specify it must be like this:
1. Which is better the black Freguenz more at 0.3 or which is 1?
2. Into which is the difference if the red line at 25 or 35 break below the 0.3 limit to what is said or otherwise increasing sales?
Thank you in advance.

@ Chris
Bernd yes you list the criteria established for itself osTests.
I think this test anyway to useless because they lack values comparable to day support, with the others (; include EBU tests) tunable.
For example there are internationally established evaluation criteria to try to establish such comparability.
Thus, the single HD format are on the MTF p.27 always measured, for example, 5 MHz, and point well below the Nyqusit border, that is at 530 TVL / ph bzw.800 TVL / ph. The resulting MTF value then gives you an impression about the contrast. This is a good comparable value on the linear part of the curve. (; For good cameras so in the 50% range for 720 and a 45% range for 1080). This tester makes it the other way around and looks for a point (and 30%) and tells them anyway you can not see any more rows.
Professional values are at 10%, which still can be lines differentiated.
In addition, there is the professional testing synonymous any values over 1000% since then klippt value. Funny as there is in these tests, but such values.
In Picture 2 is clearly an "off-set" (; see Picture 1). I do not know then, what has been set as the tester. Comparable to the tables, but this time no more.
Also it is more, as labeled, but the color resolution ... So only a tiny aspect in an overall assessment.
Perhaps a word on an appraisal. Most people evaluate a high-contrast picture, synonymous when it has a substantially less resolution than the better picture. Much contrast at low spatial frequencies. Film and television people already tend to prefer the higher resolution, if synonymous MTF values have been times not so sparkling. Finally, you can change gamma values and curves, but not resolutions.
One just adds ... such curves, as shown, can only imagine what it is all edge sharpening, or what really camera performance. The curves say absolutely nothing (about the side effects, from image defects).
Thus, and thus we would be in the assessment: From the Chromachart shows absolutely nothing.
If one or that one of the two curves in order to clean up once the offset (must, for the contrast of over 100% can not exist), so one would have to share the second bend down only once. If this is done, you get but values that would be devoid of any discussion.
But as I said ... it is a Chromachart. Camera comparisons look different from, and subjective visual impressions anyway. So it may well be that you are the images of a camera subjectively better pictures than the feel, then you go into detail but to confront the weak points out quickly.
The second camera sets high edge sharpening on low spatial frequencies. At higher frequencies we find a great extent aberrations (; Moire) and (very little useful fine structures;) resolution.
I hab'mir given time to make the curves on similar scales to .. but that would be the first overall impression does not really change.
Why do not you call us, the two cameras and let's discuss s.direkten object because chips, Lenses, image editing, format, etc. play a weighty part in the assessment of a digital camera with ... not just a detached Chromachart.

I have taken just two different views here Chrominaztestbilder from the stored database in order to understand them first once.
It is about the 1st Picture Panasonic HDC-HS300 and at the 2nd Picture the Canon HF100.
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.
