Optical technology lacks prior arrangement

Ishaq Hassan, a reader, friend of the magazine, holds membership card No. 90, and he is a student at the College of Education at the University of Riyadh - Saudi Arabia - he chose a sports project illustrated for the table tennis game - under the supervision of Dr. .. While we saw on our part what justifies its publication.

Despite the degree of “good” awarded to him by the supervising professor, Dr. Abd al-Rahman al-Shaer, our friend Ishaq saw that the photos were not fit for publication, and we apologize to the friend for publishing these photos, and we clarify the following:
In the beginning, all topics can be published in order to benefit from them in the field of right and wrong, even with repeated ideas, so how about a new idea like the one put forward by friend Isaac?

Therefore, the topics and pictures that reach the magazine become the property of the reader, who, as you say, is the basis for constantly presenting and discussing any topic from the artistic, technical and cultural angles.
So, from our point of view, the topic is funny, new, and untapped on the Arab level so far, with reference to its spread abroad. We have touched on this method in previous issues, and from here we see that sending these pictures is evidence of the existence of amateurs who are able to understand the optical orientation and exploit it in the direction of movement.

And the most important thing in the subject may be the adoption of it by the University of Riyadh, and the supervision of a doctor from the university on the subject, which supports the serious giving of a student-artist.
For our evaluation, we first stop at the point that friend Isaac referred to, which is his admission of poor light distribution, and thus the loss of prominence of the subject, for not finding a dark background with lit subjects of this type and therefore it was supposed to put the appropriate frame after determining the area of ​​​​the player’s movement, to obtain a sequence Harmonious movement here, the photographer must limit the movement to one elbow of the body, instead of moving the whole body, in addition to that the lighting must be limited to the light source that you are dealing with, which means closing the general lighting or leaking from a nearby place - in general, the knowledge of these mistakes by the friend, It means his ability to give the subject its full features in future experiments.
Finally, it should be noted that the player's snapshot - among the child's picture - is good in its idea and what it means in terms of directing the children towards sports games, in addition to the accuracy of its implementation.

Imagery techniques
The photos were taken on a slide film with a shutter speed set to (B) and an aperture of f/2.8.
With every move the player makes, he presses the flash light button to compose the full moves on one slide.

The shot of the player and the child, friend Isaac says that he took it by chance, as he took a picture of the child with a zoom lens, moving . Zoom, during capture at a speed of (B) and f / 8. Because of a mistake in transferring the film from one camera to another without attention, then the player's photo was taken with the flash at F5,6, and fortunately the first photo came identical to it.
Here, the friend adds that this photo is the most beautiful thing he took, admitting that the credit for it is due to chance.

The player's shot remains with the movement of the hand and the ball falls, and this was taken at / velocity 1/125 at F / 4⏹
