Very nice, but how do you ensure the standardized test image?
Antwort von Rudi:
The with the normalization is such a thing ...
The article is really just a matter of principle. You can buy standardized test images, but this should then filming of a light box. The ambient light should it also be normalized, the exposure of the camera synonymous, .. etc, etc. ..
Professional testing laboratories have to keep very many parameters constant in order to achieve comparable results (; and Murx as always synonymous weider itself). But in principle one can evaluate the obtained results was synonymous in Premiere. (; Although Holger Scheel would agree certainly not now). Stick words: stroke. For there to be observed synonymous much ...

If I may just add something: The edges are in the wider parts, eg 20 pixels + 20 pixels very steep. Better results are obtained when s.diesen Make a medium is inserted gray.

So if it should cost nothing, with paint or gimp:
of the right always begin knows a column, a column of black. The whole maybe 10 times then leave a little space and two black and two white columns, columns, perhaps synonymous 10th This is increased until one is left arrived. This approach has the advantage that one knows to what frequencies are (; 720Pixel in 53.3 us). Make graphics software can adjust the graduated filter synonymous, creating the much of a sweep. To the frequencies you have to do without but (; or long search).

"In order to measure the sharpness of our camcorder, we now proceed as follows: We
: Create a test image, the white and black lines can be seen. This
: Lines are always right and narrow focus is always closer
: Each other. "
Antwort von BPHennek:
Well, that's what your and your privacy?
"In order to measure the sharpness of our camcorder, we now follow. We create a test image on which white and black lines are seen to the right These lines are more narrow and are always closer to each other."

So it goes with such proposals, but only a question of readers special opportunities to which they would otherwise not care to get closer. It was not a call (; Slashcam as in the benchmark) to publish the results here. Anyone who wants to can here just once with the operation of zero carbon trade publications, testing labs, etc. . Understand Among other things, because we get requests occasionally synonymous, such as measurement results (; as we print them in our camera tests), synonymous can be created.
We use standardized course conditions, etc. a created especially for us test picture from Esser and a measurement light box with high uniformity. Also, Aperture, Distance, etc., are kept as separate as possible the same. That's the the readers does not exist, it is clear, but the principle is s.sich containing synonymous at home ...
