The Nikon D5100 is a great entry-level DSLR camera with tons of features for the beginner as well as some for the expert photographer. Laser aperture priority (A or Av mode) is probably one of the greatest among all the shooting modes. It lets you adjust the aperture setting while the camera automatically figures out for the required shutter speed to produce a proper exposure. This review shines both at the mode, Aperture Priority, with respect to the Nikon D5100 and its usage, benefits, and the best practices that can allow for using this potent feature.
Getting to know Aperture Priority mode
Before plunging into how to use Aperture Priority mode on Nikon D5100, there is also the need to understand what aperture is and why it is so much more importantly in photography.
What Aperture
Aperture is the hole in the camera lens into which light enters into the whole body of the camera. In contrast, it falls upon the image sensor and is measured in f-stops, such as f/1.8, f/2.8, f/5.6, f/11, etc. A lesser value of f-stop indicates greater aperture, permitting entry of more light while higher f-stop is lesser aperture, permitting entry of less light.
Aperture is one of the most important defining features of depth of field or DOF in an image-the distance across a photo that appears acceptably sharp. A wide aperture(low f-stop number) gives a shallow depth of field: a subject is separated from the blurred background. A narrow aperture (high f-stop number) gives a deep depth of field: both subject and background are in focus.
What does Aperture Priority Mode mean?
You’ll find a mode called Aperture Priority, where you can preset the desired aperture in your camera, and it will automatically adjust the shutter speed for correct exposure. This mode is marked as “A” in the Nikon D5100 dial.
Aperture Priority mode is widely popular with photographers concerned with making shots that depend heavily on depth of field . For instance, in portrait photography, there’s often much use of wider apertures (say f/1.8) as an element of isolating the subject with a blurred background. In contrast, narrower apertures (say f/11) would be used in landscape photography as it ensures both front and back are sharp in focus.
Why Use Aperture Priority Mode?
Aperture Priority is also a really nice mix of the two concepts-it gives power over creativity while also automating much of the work-and therefore fits most types in the photography area. Here are some of the main reasons to use Aperture Priority mode:
Control Over Depth of Field: With Aperture Priority, you obtain control over depth-of-field such that you can gain emphasis or de-emphasis on any of the subjects in the scene.
Simplifying composition: This keeps the focus on composing rather than worrying about shutter speed as the camera handles it as you fine-tune the aperture opening.
Integrated with Varying Lighting Conditions: As the camera shoots, it automatically changes the shutter speed, thus making you not worry constantly about altered lighting conditions and switching aperture settings.
Fast Action: In a constantly changing light environment, Aperture Priority mode allows you to respond almost immediately while having your aperture settings under control.
Nikon D5100: Setting Up and Using Aperture Priority Mode
To make the use of Aperture Priority mode more effective in the Nikon D5100, one should better understand the attributes of this mode. Here are step-by-step instructions on how to set up and use Aperture Priority mode:
Step 1: Change to Aperture Priority Mode.
Turn the mode dial at the top of the Nikon D5100 to “A.” Now turn the command dial, which is situated close to the shutter button, and the focus will be created by this feature now.
Step 2: Adjust the Aperture
Change the aperture that the command dial will use to set to the preferred aperture that one wants to take. The screen or viewfinder will indicate the aperture value in f-stops. Remember that lower f numbers show a wider aperture (more light, shallower depth of field), and the opposite (higher numbers) indicates a narrower aperture (less light, greater depth of field).
Step 3: Check the Exposure Indicator
According to the adjustment made in the aperture setting, the camera automatically selects the corresponding shutter speed for correct exposure. Therefore, the viewfinder or the LCD screen indicates an exposure indicator (an indicator scale that has a “+'” and “-‘). If there is incorrect exposure or overexposure or underexposure, the camera will indicate so in the indicator.
Step 4: Fine-Tune Exposure with Exposure Compensation
The exposure compensation is what you need if the exposure as set by the camera doesn’t suit you. Press the button for exposure compensation, which bears the “+/-” symbol, and while turning the command dial, increase or decrease the adjustment in exposure. It becomes most useful in tricky lighting, such as back-lighting or high-contrast situations.
Step 5: Take the Shot
When you’re satisfied with the aperture and exposure setting, it’s time to press the shutter button to take the photo. View the image on the LCD screen afterwards and make any alterations as required for other shots.
Practical Uses of Aperture Priority Mode
Aperture Priority is an admirable mode in which a practitioner might shoot almost anything. These are some of the most typical photographic scenarios in which this mode excels.
1. Portraits:
In most portrait photography, the subject is required to be isolated against the background. This is doable in Aperture Priority mode by changing to a wide aperture (low f-stop values), like f/1.8 or f/2.8. Such setting will render a shallow depth of field, thus producing a richly blurred background (bokeh), while the subject will remain very sharp. The end result will be a portrait that has a very professional look, with the subject standing against an almost soft, creamy background.
Another advantage of this wide aperture in low light is that it allows more light into the camera as it would take higher ISO or slow shutter speed to collect the same amount of light, which might introduce noise or blur.
2. Landscape Photography:
Most of the time, landscape photographers want most or all the picture in sharp focus-from foreground to background. Aperture Priority with a narrow aperture (high f-stop), such as f/8, f/11, and even up to f/16, is perfect for those requirements. With this setting on Aperture Priority, you set the narrow aperture for a deep depth of field while the camera automatically sets the shutter speed for the correct exposure.
Shooting landscapes with a narrow aperture is best accomplished with the use of a tripod, especially when the shutter speed will be longer than the normal handheld setting. This might occur under low lighting conditions or when using a polarizer or an ND filter, which will restrict the light from reaching the lens.
3. Macro Photography
Macro photography specializes in photographing little subjects at close proximity to capture such subjects as insects, flowers, and intricate details. In this type of photography, depth of field is very shallow with rates sometimes as high as f/16 or more. Aperture Priority permits you to play around with some apertures, taking some notes for future reference, in order to find that perfect sweet spot between subject sharpness and attractive background blur.
Aperture settings from f/8 to f/16 are often used for macro photography to get more of the subject in focus while still keeping a nice background blur. Since the narrow apertures usually mean slower shutter speeds, make sure you use a tripod and remote shutter release to prevent camera shake.
4. Low-Light and Night Photography
Aperture Priority is the mode one can also use for night photography and low-light photography, where one needs to capture inside light properly. The broad aperture would allow a lot more light to hit the sensor and shorten the shutter speed when the noise of movement reduces, which makes it more possible for shooting in very dim light such as at indoor events, street scenes at night, or being with the camera in concert photography.
That shooting in low light requires the combining of a wide aperture with a high ISO setting for fast enough shutter speed for handheld shooting; yet, it will increase noise, primarily at high ISO values, and might need noise reduction through post-processing.
This is also very helpful as it enlightens in action and sports photography.
Shutter Priority has always been an advantageous mode for both action and sports photography. However, aperture priority gives room to phenomenal shooting because often becomes paramount when specific depth of field is concerned. There are photographs taken from fast-moving subjects with a blurred background, where broad apertures, perhaps like f/2.8, seem to help.
Apart from that, Aperture Priority mode automatically shuts and fully sets up the speed shutter, which is correct for exposure; however, even so, one must keep quite a close eye on the resultant speed shutter so that it won’t get too low. If your shutter speed becomes too slow, increase the ISO to achieve a faster shutter speed, or switch to Shutter Priority mode to have much more direct control over how motion blur affects your subject.
Creative Effects in Action
Aperture Priority mode allows the user to be creative when experimenting with depth of field. One of the examples is shooting with a wide-open aperture to achieve a dream-like, ethereal effect or even creating images with selective focus, where only a tiny portion of the image is sharp, while other parts are soft. This is a technique that suits artistic photography, which tries to create a mood or bring out a particular feature.
On the contrary, closing down the aperture creates a starburst effect for photographing points of light, such as streetlights or the sun. The light passes through the tiny aperture blades, generating rays like a starburst. With Aperture Priority mode, you can economically experiment with various aperture settings for such creative actions.
There are great rewards concerning using Aperture Priority, but it is also challenged. When you know what challenges it has and how to deal with them, you will reap a lot of the rewards associated with shooting in this mode.
1. Limitation of Shutter Speed
Almost for the reason, the most important problem of this Aperture Priority mode in Nikon D5100 is related to the selection of a shutter speed that could be inappropriate for your particular shooting conditions. For example, in situations of really poor light, when a user would select a narrow aperture (that is, a high f-stop number), the camera would compensate by selecting a longer shutter speed. This selection could result in motion blur or camera shake, especially in handheld use.
How to Solve This Issue:
Increase ISO: When you feel that the shutter speed is too low for preventing movements, then you may increase the ISO sensitivity. This makes the sensor much more sensitive to the light that is originally intended to shorten the shuttAdded mvc.
Use a Tripod: If slow exposure is inevitable, like in landscape or nighttime photography, you can eliminate camera shake that makes for blurry images by using a tripod.
Check Shutter Speed: Check the shutter speed that is written in the viewfinder or LCD display. Any time this speed falls below a threshold (like for example, under 1/60th of a second for handheld shooting), takes action by adjusting the ISO or by putting it on a tripod.
2. Exposure Compensation
Even while in automatic operation, the aperture preference mode changes the shutter speed according to the aperture chosen by the user. There, though, will be instances when a user has to concern himself with exposure, as the camera’s meter will not be able to perfectly read the exposure: very contrasting scenes, subjects with backlighting, or bright environments or very dark will confuse the camera’s metering and cause underexposure or overexposure.
The nifty little Nikon D5100 makes it really easy to set exposure compensation when shooting under Aperture Priority. Say your photographs are becoming either overly dim or bright all the time; simply press the exposure compensation button displaying that familiar “+/-” symbol and spin open the command dial for more or less exposure as desired.
Bracket Your Shots: If in such conditions you find it difficult to manage exposure, it is advisable to bracket your shots. In bracketing, several exposures are made at different exposure levels i.e., one at the metered exposure, one a little underexposed and one a little overexposed. You will later be left with best-exposed images for editing.
3. Depth of Field Focus Decisions
Aperture Priority provides control over depth of field more than any other mode, and yet this is a very tricky mode to work in. For example, shoot at a wide aperture to bring about the shallow depth of field but with just the slightest mistake in focusing, you could get a picture with either a soft or out-of-focus subject. Otherwise, if it is a narrow aperture-for deep focus, you’ll end up with a very slow shutter speed that can bring motion blur with it.
How to Address This:
Focus Carefully: When shooting with a wide aperture, take extra care with your focus. Use single-point autofocus to ensure the camera focuses exactly where you want it, such as on the subject’s eyes in a portrait.
Depth of Field Preview: The Nikon D5100 has a depth of field preview button (located near the lens mount). Pressing this button allows you to see how much of your image will be in focus at your chosen aperture, helping you make more informed decisions.
Focus on the Hyperfocal Distance: The hyperfocal distance in landscape photography maximizes the depth of field. It requires focussing at a given distance for superior depth of field due to a given aperture with both the foreground and background being in focus.
4. Varying Light Conditions
In Aperture Priority, the camera will adjust shutter speed as per the amount of light falling on the selected aperture and the available light. However, in sudden changes of light like day-to-night shoots when tacking the shade span of light or at golden hour when changes can be rapid, this automatic adjustment may not be perfect.
How to overcome:
Be Proactive: Anticipate fluctuations in light and make the necessary alterations accordingly. For example, moving from bright sunlight into a shaded scenario might have to be counted before considering increasing ISO speeds to have faster shutter speeds.
Auto ISO: It Bill Auto ISO feature incorporated in the Nikon D5100 for such situations. This in-built feature automatically balances ISO depending on the light exposure to maintain constant exposure while the light shifts.
Shoot RAW: If captured in RAW, it offers a wider scope when processing images for recovering details lost in shifts between shadows and highlights when the light conditions changed.
5. Flash Conditions
While using Aperture Priority mode, try to understand the effects of the selected aperture on the camera’s flash system. For instance, if you shoot with a wide aperture, the flash does not have to release as much energy as with a narrow aperture. On the contrary, when using a very narrow aperture, the flash might have to work harder in low-light situations.
Adjust this:
Flash Compensation: The Nikon D5100 allows the use of flash compensation adjustment to control the output of the flash. Assume the image is overexposed when flash is used; lower the flash compensation; if underexposed, raise it.
Balance between ambient light and flash: The camera balances ambient light with the flash in a mode called aperture priority. By raising the ISO or lowering the flash power, you will declare a larger ambiance. On the other hand, when the constant intensity of the ambient light is established, the flash should be reduced in power or its intensity increased.
Try Off-Camera Flash: You could work with an off-camera flash setup if you want creative possibilities outside the shutter of the camera. It allows lighting angles and intensity for more control on either side of the flash.
Advanced Aperture Priority Techniques
Once you have mastered the basics of using Aperture Priority mode on the Nikon D5100, it is time to learn several advanced techniques that will take your photography to the next level.
1. Focus & Recompose
Focus and compose means locking the focus on the subject and recomposing the shot to improve composition. This is applied especially in aperture priority mode when you are shooting with a wide aperture, allowing you to indicate precisely what part of the image is in the sharpest focus.
This is how you do this:
Single-point autofocus with the focus point over your subject.
The shutter release is pressed halfway for locking the focus.
While keeping the shutter button half-pressed, recomposing the shot to place the subject off-center or improve the overall composition.
A fully pressed shutter button takes the shot.
This technique guarantees placing the focus on the subject while allowing for creative compositions.
2. Intentional Depth of Field Manipulation
Aperture Priority Mode offers the possibility of intentional manipulation of depth of field with an aesthetic application. For example, a picture taken with a very narrow aperture (e.g. f/22) can yield one where everything is sharp and can be used to emphasize everything in an overall scene in landscape photography. A very wide aperture (such as f/1.4) can produce an effect of highly selective focus, where only a small part of the image is sharp, drawing the eye toward a detail.
Applications:
Storytelling: Use a narrow aperture to get both the subject and the background in focus for context in telling your story. Isolation: Use a wide aperture to separate your subject from the background bringing attention toward the subject and creating a more intimate image. Abstract Photography: Experiment with very shallow depth of field to create abstract images where the subject is partly focused, allowing the majority to the imagination of viewers.
3. Panning with Aperture Priority
Panning is one such technique which is generally used in sports and action photography to convey a sense of movement associated with the image. By dragging the camera following a moving subject while using a slow shutter speed, a sharp subject image with a blurred background is obtained which shows a higher speed perception.
Steps in Executing a Panning
Set an aperture in your Aperture Priority mode to produce a slower shutter speed like 1/30th of a second.
Then focus on your moving subject and start tracking them with your camera.
Press the shutter button at the same time you keep panning across the moving subject.
Review and make adjustment to either aperture or panning speed in order to arrive at an image with the desired result if necessary.
When Panning, practice can lead to action-filled dynamic and eye-catching visual photographs of their subject moving.
Using Filters in Aperture Priority Mode
Two very general kinds of filters include the neutral density (ND) filters and polarizing filters. They are two of the most powerful filter options to improve your images, using the Aperture Priority mode.
Neutral Density Filters-
All Neutral Density filters reduce entering light for the lens, and therefore allow one to slow the shutter speed under really bright conditions. Its examples are such long-exposure effects as silky waterfall, rolling waves, or moving clouds.
Put an ND filter onto your lens while in Aperture Priority mode. Set your desired aperture, and the camera will select according to this a slower shutter speed. Stabilize the camera with a tripod for the long exposure.
Polarizing Filters:
Polarizing filters help to cut reflections and glare from nonmetallic bodies such as water and glasses and also enhance the colours of the sky and foliage.
Attach the polarizing filter to your lens in Aperture Priority mode. Rotate that filter to the favorite position, for example, to reduce reflections, darken up the sky, the camera will adjust the shutter speed to accommodate reduced levels of light that enter the lens.
Using filters in Aperture Priority mode could really add a creative dimension to you while photographing, as they can let you take images that would not be easily attainable otherwise.
Conclusion: Master the aperture priority mode of the Nikon D5100.
