Decoding values
From kamaitachi
Detailing- The number of parts in the photo. atmainlydetermined by the quality of the optics, the so-called line resolution per millimeter / inch / lb / mile, etc. how many tree branches will be seen in the photo depends on it.

Sharpness- sharpness of the border between the contrasting parts of the frame. it depends on how clearly the twig will stand out against the sky. very dependent on sharpe level during processing. an unnecessary sharpe - the twig will be drawn with a bold marker, it will appear "indented" into the frame and an unpleasant halo will appear around it to underline the borders of the twig.

White balance- a difficult discipline, if greatly simplified, the image can be warm (care in yellow / red / orange), cold (blue) or dead (green, especially tin when a person’s face goes green). A good bb is when the picture looks natural, and not blue / green / yellow, etc. Not always good bb coincides with the real. there are nuances.

Colour- also a difficult discipline. usually means smooth tonal transitions, the number of semitones, but again there are nuances. if there are fewer colors, the color looks richer, but the transitions between the shades with sharp edges, a large number of halftones look smooth, but pale. Here is such a paradox.

Exposition- very simplistic lightness of the picture. depends on shutter speed, iso and aperture. since the diaphragm is fixed in mobile phones, it is only from ISO (the higher, the brighter, but noisier) and the shutter speed (the longer, the brighter, but the more chance to get a lubrication). More already on the photo sites, the topic is sucked millions of times.

Dynamic range- roughly speaking, the number of gradations between the lightest and darkest part of the photo. measured in feet, which are 2 to the power of X. The picture is filled with one color - 0 stops (2 ^ 0 = 1), the picture of black and white pixels is 1 stop (2 ^ 1) and so on. usually there are 9-10 stops in a mobile phone, up to 16 in cameras, more than 20 in an eye (it depends strongly on a homo sapiens specimen). how much detail the camera captures in a contrasting scene (the sun in the frame) depends on dd. the fully illuminated sky and the black earth are narrow dd, the point light on the sun and on earth many details is wide dd.

Composition- in the frame, the eye must cling to something. Usually catching the eye with contrasting objects, leading lines (lines along which the viewer's eye goes, it is also desirable to lead to the main objects), angles or broken / wavy lines in the frame. The frame should not be empty, but you should not take photos of only one object. All objects have an environment, a background, a world around them with which the object interacts. For example, in a portrait (except for a studio on a monophonic background) a man looks better against the background of the embankment, forest, city than just against the sky. The main mistakes in the portrait are the branches growing from the head or the body, the pillars, the background merging with the person, the background is much brighter than the person, the colorful background distracting attention, the dirty background (trash cans, debris, dirt), the unnatural position of the person’s body, protruding elbows, hands are not on place, framing of the joints (so the person becomes a "cripple"), unnatural emotions (permissible in fashion and advertising), unnatural complexion (the so-called skinton). In landscape photography, the presence of front, middle and long-range plans, the presence of perspective, recognizable colors, the presence of balance in the frame (so that it doesn’t visually appear that one edge outweighs the other), a level horizon (funny, but a couple of degrees of obstruction are already visible) it is uncomfortable to look at such a landscape to the eye and to the person), the presence of the main object of shooting (lake, lonely tree, mountain).

In general, if the eye clings and there is a main object not too far away and not from edge to edge of the picture, harmonious (very simplistic - pleasant for the viewer) colors are good. Errors voiced above (branches from the head, littered horizon, no main object, colorful background) - bad.

What is the difference between "color" and "detail" on the basis of the above definitions?

color - the number of shades on the branches, detail - the number of branches themselves. Sharpness - the clarity of the boundaries of the branches.

From sparta

Sharpness- natural clarity of physical objects in the frame. If the object in the frame is out of focus, then it looks fuzzy, blurry, i.e. not sharp.
Not all objects in the frame must necessarily be sharp, for example, in portrait photos, the face of a person in the foreground usually looks clear, but the background is blurred, i.e. not sharp. Nevertheless, such a photo is considered "sharp". But if the face turns out to be blurry in the portrait photo, then this photo as a whole is considered not sharp.
The word “natural” in the definition above means that there is an unnatural, artificially wound (enhanced by the software processing of the camera's algorithm) sharpness. Such overly enhanced sharpness is called “overshoot”, and in a real photo this is manifested in the fact that contour lines (edging) appear on the borders of objects that are not present in the real scene with eyes. For example, in the case of overhaul, the branches of a tree will have a white outline against the blue sky. To see this clearly, it is usually necessary to slightly zoom the part of the photo on the screen on a larger scale (called “cropping”), but on the frames of some smartphones the “overshoot” contour is visible without approximation.
Sharpness and rehashing interrelated concepts: Insufficient sharpness leads to blurring of the object in the photo, and excessive sharpness, to rehash.
The photo should be considered "with good sharpness", when, on the one hand, the object looks clear, and on the other, there are no signs of overshoot.

Detailing- characterizes the number of small parts that can be seen in the frame. In order to "see" small details, a photo is usually required on the screen when viewing a bit closer on a larger scale, to make a "crop". The more small details in the photo at the same time have distinguishable and recognizable outlines, the higher the detail. An example of good detail is the readable number of cars in the background of the photo.
Detailing and sharpness are somewhat different concepts, for example, a photo can have excellent sharpness, and at the same time no detailing, simply because it is elementary for a camera that lacks megapixels for good detail. If we speak conventionally, then on a camera with a 2 megapixel matrix now in 2018, it is simply physically impossible to get a picture with good detail, no matter what the picture is perfectly sharp.

Colour- Accuracy of color transfer of real objects in a photo.
Since in order to assess the color correspondence of all objects in the frame, it is obvious that you must be present at the shooting location with the photographer in order to see the color "by his eyes", then you can discuss the accuracy and color saturation ONLY AT LEADABLE OBJECTS. However, you are fine with the concept of "color" can appreciate the fading of the photograph as a whole, or, for example, the lack of saturation of red, which also goes into a carrot tint. The concept of "color" can also describe the overall loss of color saturation of a photo when shooting in a lack of light (sometimes reaching up to a b / w photo, for example, in some models of apple products). It is also easy to identify the unnatural poisonous green color of the grass or the violet blue of the sky.
At once it is necessary to say that with regard to color, it is advisable to look at a hardware-calibrated monitor and without fail in the same color space. If you look at photos taken in sRGB space on a monitor with an extended color gamut, then instead of those colors that you can see in this photo, you will see a supersaturated crimson instead of purple-red, and poisonous acid greens instead of green grass. Fortunately, most monitors (so far) work in sRGB space, and most cameras shoot in it. This is the main thing.
As for the hardware calibration, on an uncalibrated monitor, for example, the shade of the blue sky may not correspond to what is actually in the photo: instead of the pale blue you will see a light green velvet or care to the violet.

White Balance (BB)- this is not a color! A good BB implies the natural overall color tone of the photograph as a whole, corresponding to the lighting of the scene being shot, and not at all the correspondence of the color of individual objects in the frame. Photos with a bad BB can look like generally "bluish", pink or covered with a green tint. For example, if instead of the expected gray clouds on a well-known shooting scene (like 1000 times shot this and I know how it really looks), you will see pink clouds (Lumia 950 XL on a cloudy rainy day), then this is a clear reason to doubt the correctness of BB on this frame. Keep in mind that BB very much depends on the light of a particular scene. On another stage, the same device will give the perfect BB! This is important to consider.

Exposition- everything is simple: the frame may be either overexposed or, on the contrary, too dark if the exposure is selected incorrectly. It is determined by eye immediately and without difficulty.

Dynamic Range (DD)- the ability to distinguish the details of different brightness in the bright parts of the frame (in the "highlights") AND SIMULTANEOUSLY distinguish the details of slightly different "darkness" in the dark parts of the frame (in the "shadows"). A good example of a good DD is a frame with a window, shot during the day from the depths of the room, where interior details are clearly visible, and what is on the street outside the window. On a frame with a bad DD, either the interior will be visible, and the window, and what is behind it, will be flashed white, or the window will be visible and what is outside the window, and the room will be completely black.
If the device has a bad DD, then the choice of exposure cannot achieve both clearly visible details in the “highlights” and distinguishable details in the “shadows” SIMULTANEOUSLY. Either one or the other. On a device with a good DD this is possible.

Composition- a harmonious combination of frame elements, highlighting the main idea or the semantic component of photography. In the composition, the rule of minimalism usually works, when the elements of the frame that do not carry a semantic load only clutter the frame and are "noise" that violates the integrity of perception. Such a “noise”, for example, is the wires in the picture of the church (God forbid also in the foreground or against the background of the domes). The correct compositional decision in this example will be the choice of such a shooting angle, when these wires, if not present in the photo at all, then at least “do not look into your eyes” clearly. Sometimes, if this is not possible, it is better to refuse such a frame altogether than to shoot a deliberately disastrous scene.
However, it should be noted that the presence of wires in the frame itself is not yet “evil” and depends entirely on the idea that the photographer wants to convey to the viewer. For example, if the idea of ​​a photo is a technotronic apocalypse, predicted by Nostradamus as "... And the sky will be covered with cobwebs", then a pole with a million wires and cables to it, shot in the frame with the right angle (not necessarily the central element of the plot), can be very appropriate.

Composition is entirely connected with the subjectivity of the perception of what is seen by a person, which nevertheless has objective laws. Examples of such laws are the arrangement of frame elements according to the rule of two-thirds, the golden section, etc. All this is at the level of the subconscious perception of the frame as "harmonious." Special attention should also be paid to the purely technical aspects of the survey, such as the leveling of the horizon.

It is important to note that the technical capabilities of the apparatus itself influence the choice of the composite solution. For mobile cameras, this primarily refers to the optical zoom capability (not digital, digital zoom is evil). Sometimes it's just impossible to get closer to the subject to get the right solution, and then the zoom helps out. Similarly, about the possibility of portrait mode, and about wide-angle shooting.

In portrait photography in the compositional plan, special attention should be paid to the light, and at the same time the features of the smartphone itself should be taken into account. For example, even with the seemingly exposed to all the canons of the world, when shooting on the latest models of iPhones, you can easily get the light of the yellow spots on the forehead or nose of the model. Such a frame is technically immediately go into the trash.
Also important is the background, even if it is blurred.
The model also needs to be “combed”, and not only literally. Hair can also be slightly disheveled, but from the turn / tilt of the head and the direction of gaze, as well as from sometimes with the careless grace of the overlaid garment, the complete perception of the photo as a compositionally finished picture depends.

Be honest with yourself!
Make an assessment sincerely, and not out of personal sympathy or dislike for the participant./device
