In mid-15c. it also meant "frame of mind," often implying a pious or moral determination. By 1580s as "a statement upon some matter;" hence "formal decision or expression of a meeting or assembly," c. 1600. The New Year's resolution in reference to a specific intention to better oneself is from at least the 1780s, and through 19c. they generally were of a pious nature.

As a portrait photographer, you’re most concerned with photographing the unique, defining features of your subject; the bright sparkle in an eye, the freckles on a face, the tiny wrinkle in a chin. Images like this aren’t possible without understanding how to use depth of field (also known as focus range) to bring certain parts of your image into focus and blur out what’s less important.

In Middle English also "vaporize a solid, condense a vapor into a liquid, etc.;" a mid-15c. document has Sche was resoluyd in-to terys where a later writer might have she dissolved in tears. Related: Resolved; resolving.

By following these tips outlined above, you should now be able to generally control your depth of field to take the images you want. The more you practice and experiment with aperture, distance, and focal length, the more you’ll be able to fine-tune depth of field in your images to enhance your individual photography style.

Depth of fieldphotography examples

Set your f stop to a high number (for example, f/11). This will narrow your aperture, and you will let very little light into the lens. To compensate and to avoid having an underexposed image, you will need to shoot slower by adjusting your shutter speed. Your resulting depth of field will be deep.

To gain a top-level understanding of how you can achieve shallow or deep depth of field by controlling aperture, here is a quick overview of aperture and its related elements: F-stop, shutter speed, and depth of field.

This is from re-, here perhaps intensive or meaning "back" (see re-), + solvere "to loosen, untie, release, explain," from PIE *se-lu-, from reflexive pronoun *s(w)e- (see idiom) + root *leu- "to loosen, divide, cut apart."

Simply explained, the term 'depth of field' refers to the area of an image that appears to be in focus. As the distance from the focal point increases, the focus gradually decreases until it appears to be out of focus. In any image, there’s a point of absolute focus and a corresponding region of the image surrounding the subject that appears to be in focus.

While distance plays a large role in depth of field, knowing how to adjust the f-stop to compensate for distance is often a much more convenient way to achieve your desired depth of field. This is especially true in landscape photography, where moving farther from a subject in any significant way is much more difficult than it is in close-up photography.

Learning to control depth of field will help you bring focus to the most important parts of your images and will greatly improve the technical and aesthetic quality of your photos.

Aperture is not infinite; all lenses have their limits, which are clearly defined by the manufacturer. Manufacturers state a minimum and maximum range that the lens can be shot.

Understanding depth of field is important and can greatly influence your photography; it helps distinguish the foreground from the background to create a focal point that draws the eye and tells it where to look. Knowing how to control depth of field gives you the opportunity to choose how much of (and what parts of) your image you want to bring into focus.

late 14c., resolucioun, "a breaking or reducing into parts; process of breaking up, dissolution," from Old French resolution (14c.) and directly from Latin resolutionem (nominative resolutio) "process of reducing things into simpler forms," noun of action from past-participle stem of resolvere "to loosen" (see resolve (v.)).

From the notion of "separate into components" comes the sense in optics (1785; see resolution). From the notion of "reduce by mental analysis into its basic forms" (late 14c.) comes the meaning "determine, decide upon" after analysis (1520s), hence "pass a resolution" (1580s); "decide, settle" a dispute, etc. (1610s). For sense evolution, compare resolute (adj.).

If an image has a deep depth of field, it means its area of perceived focus is a broader and deeper portion of the image. If an image has a shallow depth of field, it means its area of perceived focus is limited to a narrower range.

If you shoot in anything other than a totally controlled environment, you have to know how to adjust your camera for the changing light. Aperture is the part of the lens that controls the amount of light passing through to the camera’s sensor, and its one of the simplest ways to control the depth of field. You can change the access of light by widening and narrowing the diameter of the opening through which light enters the camera.

Without getting too technical, it’s important to note that this apparent change in depth of field when applied at a closer or farther distance has everything to do with the portion of the frame that the subject fills. With magnified shots, less of the background is represented in the shot, and the blurred background is magnified, making the image appear to have a shallower depth of field. The inverse effect happens when an image is taken at a farther distance.

late 14c., resolven, "melt, dissolve, reduce to liquid; separate into component parts; alter, alter in form or nature by application of physical process," " intransitive sense from c. 1400; from Old French resolver or directly from Latin resolvere "to loosen, loose, unyoke, undo; explain; relax; set free; make void, dispel."

The meaning "steadfastness of purpose" is by 1580s. The meaning "effect of an optical instrument in rendering component parts of objects distinguishable" is by 1860. In Middle English it also could mean "a paraphrase" (as a breaking up and rearranging of a text or translation).

Wider aperture, when applied at a distance (physically, or with a shorter lens) from the focal point, results in an apparent deeper depth of field than it does when it’s applied to a closer subject.

Set your f-stop to a low number (for example, f/2.8). This will widen your aperture, and you will allow a lot of light into the lens. To compensate for the flood of light you need to shoot faster by adjusting your shutter speed. Your resulting depth of field will be shallow.

As a landscape photographer, you capture sweeping images of oceans capes, mountainsides, skylines, and wilderness. Your photos thrive on dramatic details viewed from close up and far away: Trees, birds, blades of grass are brought into focus to set the perfect stage.

It emerged c. 1500 in the sense of "determined, decided, absolute, final," especially in the phrase resolute answer, which was "common in 16th c." [OED]. The notion is of "breaking (something) into parts" as the way to arrive at the truth of it and thus make the final determination (compare resolution).

Shallowdepth of field

Shallow depth of field is a great way to bring focus to a specific subject to separate it from its background. Shallow depth of field is commonly used in portrait photography and food photography. It is also great for action photography, such as sports and wildlife photography, because it separates the subject from their chaotic background and allows you to shoot with a quick shutter speed to capture crisp detail in action.

Inversely, when you shoot the same subject at closer distance (physically, or with a closer focal length), you’ll notice a shallower depth of field.

Referring back to the example in the introduction, landscape photographers typically want to capture a deep depth of field, where most of the image is in focus, from the foreground to the background. Portrait photographers typically want a shallow depth of field, where a smaller plane of detail in an image is sharpened, and any distractions in the background that may take away from the detail of the face are blurred.

Depth of field

early 15c., "dissolved, of loose structure," also "morally lax" (senses all obsolete), from Latin resolutus, past participle of resolvere "untie, unfasten, loose, loosen" (see resolve (v.)).

From the notion of "process of resolving or reducing a non-material thing into simpler forms" (late 14c.) as a method of problem-solving comes the sense of "a solving" (as of mathematical problems), which is recorded by 1540s, as is that of "power of holding firmly, character of acting with a fixed purpose" (compare resolute (adj.)).

Depth of field is not equally distributed around the focal point. It is typically distributed unequally, with about 1/3 of the total field of focus lying in front of the subject, and two-thirds of focus lying behind the subject.

Deep depth of field is a great way to bring out detail in a large portion of the frame. Deep depth of field is commonly used in landscape photography to capture elements and textures in the majority of the frame throughout many vertical planes. To capture fine detail and deep depth of field, you should use a wide-angle lens to shoot at a distance and set your f stop at a high number for a small aperture.

The word has been used from 1530s of persons, "determined in mind, having a fixed resolve." Related: Resolutely; resoluteness. In Middle English a resolutif was a medicine to dissolve and disperse hardened matter (c. 1400).
