What do f-stops and shutter speeds do and how do they impact a photograph? Determine the proper f-stops and shutter speeds that you would use for the following photographs and briefly explain why you chose each setting for each image
Image #1: An outdoor photo with bright, natural light
Image #2: An evening photo with low light
Image #3: Indoor photo with medium light
The f-stops and the shutter speed allow to control the intensity of the light that reaches the sensors,
The answers for each case are:
a) fast speed and large f-stop
b) slow speed and small f-stopr
c) intermediate speed and average f-stop
given parameter
a) photography in bright light
b) night photography, low light
c) interior photography, half light
to find
* f-stop
* shutter speed
In photography, the intensity that reaches the sensors is proportional to the aperture of the diaphragm and the shutter speed, the quality and sharpness of an image is directly related to the intensity received.
The f-stop is defined by the relationN = f/# = f / D
where N or f/# is de f-stop, f is the focal length and D the diameter of the lens opening.
The amount of light that reaches the film has two dependencies:
* Proportional to the lens area, which varies with the diameter square
* Proportional to the image area, if we assume that the object is at a much greater distance than the focal length, the image distance is equal to the focal length, therefore the further away the sensors are the lower the intensity.
We can say that the intensity is inversely proportional to the focal length squared
From these two expressions, it turns out that the intensity is
I = (D / f) ² = [tex]\frac{1}{N^2}[/tex]
The shutter speed is inversely proportional to the time the shutter is open for the sensors to check the light, it is expressed in seconds and fractions. I = t = 1/vwhere t time and v es shutter speeid
In summary, the intensity received by the sensors is inversely proportional to the f/# and the shutter speed
Let's apply to the proposed situations
a) Photo outdoors in bright natural light.
In this case, as there is enough light, we can use a large one, so that a little amount of light passes through and also use a short shutter speed
decrease the f-stop so that the less light the system and that the photograph is not overexposed. This gives us an advantage, by having a diagram with a small aperture, the rays that pass are para-axial, therefore the background will be seen clearly.
Typical values for this situation are fast speed ( s or less) and f-stop of f/8
b) night photography in low light
in this case the shutter must be opened, for this decrease the f-stop so that the more light the system
In addition, the shutter speed must be reduced so that there is more time for the exposure of light
Typical values are speed of s or less and f-stop of f / 1.6 or less
in this case the background of the photograph becomes blurred
c) indoor photography with half light.
In this case, a medium speed and a medium shutter aperture must be selected with f-stop.
In this case the object of interest is exposed and part of the phone is lost
The typical values of shutter speed are s or s and the aperture of the diagram to achieve a good exposure, the most types f-stop are f/2.8 or f/4
With the f-stop control and the shutter speed, we can control the intensity of the light that reaches the camera's sensors for a good photo.

When criticizing an artist's technical skills, the critic should consider
A. his personal opinion of the artwork.
B. the style of the artwork.
C. the creativity of the artwork.
D. the beauty of the artwork.
When criticizing an artist's technical skills, the critic should consider the style of the artwork. The right answer is B.
When critiquing an artist's technical skills, considering the style of the artwork is crucial. The style encompasses the chosen techniques, methods, and aesthetic choices that contribute to the execution of the artwork. Evaluating how effectively the artist has applied and manipulated these techniques within the context of their chosen style allows for a more objective assessment of their technical proficiency.
This approach avoids subjective judgments based on personal opinions, focusing instead on the artist's ability to achieve mastery within the parameters of their artistic expression. Analyzing the artist's technical skills through the lens of the artwork's style provides a well-rounded evaluation that transcends personal preferences.
The correct answer is option B.

Which type of space is in the center of the circle in the sculpture?
A.Abstract
B.Open
C.Perspective
D.Positive
Answer:
B
Explanation:
Open space if I’m not wrong
The correct option is B. Open space is in the center of the circle in the sculpture.
The circle is seen as a symbol of unity because it encompasses all regular polygons. The pinnacle of geometric symbols also represents infinity, which has neither beginning nor end.
What is the symbolic meaning of a circle?The circle has established itself as one of the oldest geometric symbols and gained recognition and respect in both education and society. It is a worldwide symbol that is revered as a sacred emblem across practically all cultures. The circle stands for unbounded concepts like eternity, monotheism, oneness, infinity, and totality.
As in the fundamental geometric shapes of the sphere, cube, pyramid, cone, and cylinder, geometric forms are those that are mathematical, exact, and able to be named. In three dimensions, a circle becomes a sphere, a square a cube, and a triangle a pyramid or cone.

Beth has an image of an old house. She found that some areas of the house seemed darker than the rest. She wanted to lighten particular areas, while keeping the other areas as they are. Which image-editing tool can Beth use to lighten the selected area? A. brighten B. burn C. dodge D. contrast Reset
Answer:
dodge
Explanation:
Dodge is used to brighten specific areas of a photo while burn is used to darken specific areas
Beth can use the dodge image-editing tool to lighten the chosen area. As a result, choice (C) is the best way to respond.
What is Dodging and Burning?Dodging and burning are phrases used in photography to describe a technique used to alter the exposure of specific portions on a photographic print while diverging from the exposure of the remainder of the image. Dodging reduces exposure for portions of the print that the photographer wants to be brighter, while burning raises exposure for areas of the print that the photographer wants to be darker.
To cover and/or disguise the target region for burning or dodging, any substance with varying degrees of opacity may be utilized, according to preference. To burn or dodge an area, one can use transparency with text, graphics, or patterns, a stencil, or a completely opaque substance that has been cut to fit the desired area.
Hence, option (C) is accurate.

Answer:
Two methods of establishing approximate dates for prehistoric objects are relative dating and stratification. Option (C).
Explanation:
Stratigraphy is the most established of the relative dating techniques that archaeologists use to date things.
Stratigraphy depends on the law of superposition like a layer cake, the most minimal layers probably been framed first.
Separated stores might incorporate soils, residue, and rocks, just as man-made provisions significantly further developed removal and archaeological dating techniques.
