Evaluation of film camera image resolution focus focus YETE158 test card. The image quality assessment test card TE158 is designed to evaluate the image quality of film cameras and can be used in different formats of cameras. It consists of sector stars, several test elements, linear gray levels, and nine test blocks. A test chart is designed to evaluate the image quality of a film camera. It can be used in different formats of cameras. It has the following aspect ratio format tags:
1:1.375 35mm
1:1.66 S16mm
16:9 PAL Plus / HDTV
1:1.85
1:2

There are 3 different reduction markers:
35 mm film with 7.5x, 25X and 45x
S16 has 80.5x, 44.5x, and 13.4x
The image mounted on the stable 10mm plastic plate is composed of different test elements as described below:
1 and 16 stars with 36 sectors, 80mm in diameter, and 4 fan-shaped stars in diameter of 25mm. Fan segments are used for focusing cameras and for simple visual evaluation of the tested lenses.
2, test elements (TE142) are usually used for test resolution. In each group, right angle are two from C to K marker, and by a factor of 2 grade b.. This means dividing the number of rows in each of the two steps

Two. There are three different sizes of test components not only based on three different resolution scales, but also providing a higher range of possible resolution measurements. The resolution based on the scaling and field mark is given in the following table.
3 and 9 color blocks are used to evaluate the color reproduction of film material. The color section corresponds to the color of the Macbeth ColorChecker.
4 and nine order linear gray levels (D = 0.2-1.8).
