Advanced modes
Taking photos

The “advanced” modes, or PASM modes, are used by experienced photographers because they make it possible to adjust the camera’s exposure settings, including shutter speed, aperture, and sensitivity. In this way, your DxO ONE gives you the same degree of control as a DSLR.

P mode – Program

A mode – Aperture priority

S mode – Shutter priority

M mode – Manual

When one of the advanced modes is selected, the left-hand toolbar will expand to display the controls:

Each of these setting options is described in detail in section “Shooting settings”.

P mode – Program

The Program mode is primarily an automatic mode. However, it still lets you control your shooting settings by allowing you to choose a shutter speed/aperture combination that is different from the one suggested by the camera. In this case, the exposure and ISO sensitivity level stay the same.
This mode lets you immediately adjust either the aperture to suit your desired depth of field, or the shutter speed to capture precise movement or create a blur to suggest motion.

Use this mode for:

Taking photos that don’t need special settings, while still being able to modify them.

Taking photos in good lighting conditions while striking the best balance between aperture and shutter speed.

Controlling the ISO sensitivity while allowing the DxO ONE to automatically choose the other exposure settings.

Select to launch the Program mode.

In Program mode, exposure is always kept constant. The sliding menu displays nine levels representing increments of 0.3 EV. This lets you adjust your aperture by 3 EV in either direction and maintain consistent exposure levels, inasmuch as the shutter speed will vary depending on the aperture.

The settings will also be displayed on the DxO ONE’s OLED screen.

Examples:

Outdoor portrait: When shooting outdoors, the automatic control feature offers a balanced shutter speed/aperture combination, e.g. 1/500 s with ƒ/4.5. If you want to separate the subject’s face from the background with a subtle background blur, tap on the shutter speed and aperture icons in the left-hand toolbar, then move the sliding menu down to widen the aperture.

The effect is shown on the menu on either side: wide aperture and fast-moving subject at the top, narrow aperture and static subject at the bottom. You can adjust the program to reach up to 1/2,500s with ƒ/2.

Motion blur: Conversely, you can narrow the aperture even more to increase the exposure time and produce a motion blur in the background. This effect gives the impression of speed.

You can also set the ISO sensitivity at a given value to minimize digital noise in low light conditions. Please note this will force the DxO ONE to select a slower shutter speed or a wider aperture, which may lead to a motion blur or too shallow a depth of field.

A mode – Aperture priority

A mode – Aperture priority, is semi-automatic. In this mode, aperture must be adjusted manually. The DxO ONE then automatically chooses the shutter speed and ISO sensitivity that will provide the correct level of exposure.

Use this mode for:

Controlling the depth of field. Opening the aperture produces a blurred background; closing it extends the area of the image that is in sharp focus.

Optimizing image quality in low light. Opening the iris as much as possible maximizes the amount of light captured by your DxO ONE, allowing it to choose a faster shutter speed (= clearer image) and/or a lower sensitivity level (= less digital noise).

Select to launch Aperture priority mode.

This mode lets you change the Aperture setting options. Tapping the aperture control icon will open the aperture slider. To adjust the aperture, move the aperture slider up or down to select the desired setting. You’ll immediately see how the new setting changes the image’s depth of field.

The settings will also be displayed on the DxO ONE’s OLED screen.

S mode – Shutter priority

S mode – Shutter priority is also a semi-automatic mode. In this mode, you set the shutter speed, and the DxO ONE automatically chooses the aperture and ISO sensitivity levels to produce the correct exposure.

Use this mode for:

Creating motion blur. To produce a blurred effect indicative of movement or make running water look soft, select Shutter priority mode and adjust the exposure time. Starting at 1/30 s, you’ll start to notice motion blur. For exposure times longer than 1/4 s, we recommend using a monopod or tripod.

Preventing motion blur in a photo. When photographing sports scenes (biking, skiing, etc.), you can capture the movement by using Shutter priority mode and selecting higher speeds (1/200 s and over). You can also use Shutter priority mode in low light in order to capture a specific scene. Make sure the ISO sensitivity is in automatic mode, then set the exposure time to 1/50 s.

Select to switch to Shutter priority mode.

This mode activates the camera’s Shutter speed setting options. The sliding menu opens when you tap the shutter speed icon. To change the shutter speed, move the sliding menu up or down to select the desired setting.

In artificial lighting, certain speeds can produce colored bands on your images.

M mode – Manual

M mode – Manual lets you adjust all the camera’s settings, including shutter speed, aperture, and sensitivity. Unlike the automatic and semi-automatic modes, adjusting these settings does not affect any other setting. If you wish, you can work in Manual mode while keeping automatic ISO sensitivity level.

Use this mode for:

Ensuring constant exposure across a series of images, such as a panorama, for example. Make an average measurement in P, A, or S mode, then switch to M mode to lock in the settings.

Taking photos in conditions that do not require constant setting adjustments, particularly if the lighting doesn’t change (landscape and architecture), while keeping control over all settings simultaneously.

Taking astronomical photos.

Working with studio lighting. Measure the light using a hand-held exposure meter, then transfer the shutter speed and aperture settings for a given sensitivity to the DxO ONE.

Precisely controlling the ambient light/flash fill ratio.

For taking creative photographs and for enjoying having complete control over the settings for any given scene.

Select to switch to Manual mode.

A menu will appear on the left-hand side of the iPhone’s screen. Tapping each icon lets you open the associated sliding menu.

To adjust the settings, move the aperture sliding menu up or down to select the desired setting.

You can immediately see how your chosen aperture setting affects the depth of field, just as in A mode.

In M mode, the exposure level shown on the screen does not correspond to the actual exposure level of the final image. Monitor the exposure indicator at the bottom of your screen to see if you start to stray from the camera’s optimum exposure levels.

You can use the Auto ISO sensitivity option to have the camera automatically select the exposure while still maintaining control over the depth of field via the aperture and motion blur via shutter speed.

For taking long-exposure photographs in daylight or maintaining a wide aperture without over-exposing your images, you can use a neutral density filter. This reduces the amount of light that enters the lens without affecting image quality. A selection of filters and the “Optical Adapter,” an accessory that lets you add lenses to your DxO ONE, are sold separately on our online store.

In artificial lighting, certain speeds can cause colored bands to appear on your images. For more information on this subject, see section “Shooting settings” .
