Every question has an answer

Aperture and color saturation

I have a question attached to a form;
What are the caveats of using a very narrow lens aperture - 32 for example - regarding color saturation and image clarity, as I learned in previous issues of “The Art of Photography” that it is imperative, in order to obtain maximum clarity and accuracy, to use the minimum aperture as possible, knowing that the attached pictures were taken at shutter speeds Different, aperture 32, and the result is bad, in my opinion. As you can see, it is not hidden from you here that the time for taking pictures, as shown in the pictures, is after afternoon, and this castle is called Al-Rahba Castle »near the city of Al-Mayadeen, which is about 45 km away from Madinaty.
There is another question, please tell me the specifications of the Pentax LX camera. Does it produce color films with a sensitivity of less than 100 aza?

And I have one last request.. I hope that you will publish some information about industrial photography, because I would like to know about this field. Information about him is very little.

If we look at the submitted samples - which were originally taken in color - we find that the third shot has been oversaturated
My color is wonderful, while the first scene is clear that it lacks part of the exposure, so the saturation is weak. The second scene remains, which is very close to the third scene. Thus, we find the opposite of what you found. Rather, the result is considered very satisfactory, and there are no caveats here about color saturation, as long as you photograph under sunlight, and if it is preferable to adopt an aperture of 16 to ensure full saturation, then usually when you mention the word maximum aperture, we mean by that F / 16 Nevertheless, we find that the third scene was fully saturated, and the evidence is first of all the clear blue of the sky, and therefore the color of the magnificent castle stones and the extension of the dark color of the earth.

And if we look at the first picture, we see that it is actually underexposed, and therefore weak in spread, so it appears pale and lacks clarity and accuracy of details. As for the fourth scene, it is clear that it is flickering and lacks a degree, so that it becomes fully exposed. And the fifth scene came with full standards.

The main dilemma remains with such scenes. Firstly, it is preferable not to use focal length lenses
High - Telephoto - Since these lenses are unable to absorb the desert atmosphere and the dust in the atmosphere ...
There are lenses whose prices are very high, and they work to purify the air from desert fog or flying dust that we may not see with the naked eye. It is preferable to capture natural scenes with the standard lens.
If necessary, then you should use a filter. (Polarizing).
With regard to your question about the Pentax camera, the types of these cameras can be considered good, including the type mentioned by you (LX), which works according to automatic programming, that is, you can use the shutter speed manually or automatically.
This means that the shutter speed is preferred. When you select the lens aperture on your camera, the camera will work, when it is on an automatic position, to choose the necessary speed. This camera is characterized by a shutter speed of up to 1/2000 - as for the rest of Pantax cameras, its shutter speed reaches 1/1000. The sensitivity of the film is from 6 aza up to 3200 aza, which means that you can use any film you want. Here we point out that the camera has nothing to do with the production of color films at all, so as long as you use a color film, you will get your colored pictures.
About industrial photography, we will later mention a comprehensive topic within this field ⏹

⏺ Camera and lens protection

I recently bought a Hazelblad camera (500c/M) and I got good results from my photography with this camera, and as you know that the weather in Saudi Arabia is very dusty, so what do you advise me to keep this camera? Note that I followed more than one method, such as aluminum or leather bags, but I sometimes find some dust on the lenses and the camera body. There is also a well-made bag made by the same company, but its prices are exorbitant and range between 1000 and 2000 riyals, and this amount is equivalent to a third of the value of the 50mm lens.
Please let me know and thank you very much.

You have an excellent camera and you have to protect it in the best way.
The problem of dust is a natural thing and it is possible to remove it from the body of the camera with a piece of cloth, and it is preferable to use soft leather to remove it.
As for the lenses and the accumulation of dust on them or their exposure to shocks, scratches and the like, it is very important, from here you have to adopt protective filters (Sky Light Filter) and for each lens a filter, it is better a thousand times to change or scratch the filter than to damage the lens, given its exorbitant price and thus the price of the filter remains Not mentioned for her.

And for complete protection, after completing the external photography operations, you are supposed to wipe and clean the camera body and the filters before placing them in the designated bag.
The best for these types of cameras is the aluminum bag, due to the compartments inside it that are designed to put each piece in its place without moving, to close it tightly. Due to the high prices - as for the price, it is the same⏹
