Shooting Modes for E-M10 Mark IV

AUTO mode
The camera automatically adjusts the settings best suited for the scene, which is convenient for beginners. Use the Live Guide to easily adjust color, brightness and background blurring.
Camera settings cannot be changed except some settings, because this is an automatic mode.



SCN (Scene mode)
This mode enables you to shoot in the appropriate settings by selecting a sub mode best suited to the subject or scene.
Select a general situation in sub mode 1, and then a more specific mode in sub mode 2. Camera settings are limited to maximize the effect of each Scene mode.
Refer to the following question for more information:
What kinds of SCN (Program shooting) modes are available?

Sub Mode 1 (Subject type)	Sub Mode 2 (Scene mode)
People	Portrait, e-Portrait, Portrait + Landscape, Portrait + Nightscape, Children
Nightscapes	Nightscape, Portrait + Nightscape, Handheld Starlight, Fireworks, Light Trails
Motion	Sport, Children, Panning
Scenery	Landscape, Sunset, Beach & Snow, Panorama, Backlight HDR
Indoors	Candlelight, Silent, Portrait, e-Portrait, Children, Backlight HDR
Close-ups	Macro, Nature Macro, Documents, Multi Focus Shot

AP mode (Advanced Photo mode)
This mode enables you to take creative photos unique to D-SLR cameras.
Advanced shooting modes like Live Composite, Multiple Exposure and Live Time can be set with a simple operation.

While SCN modes such as Silent, Panorama and Light Trails achieve effects that are similar to the Live Composite in AP mode, more advanced settings are possible in AP mode than in SCN mode.

Refer to the following question for more information:
What kinds of AP modes are available?

AP mode
Live Composite, Live Time, Multiple Exposure, HDR, Silent, Panorama, Keystone Compensation, AE Bracketing, Focus Bracketing

Art Filter
You can take creative pictures using art filters. The effects of art filters can be checked on the live view monitor before shooting, so you can select a desired art filter by checking the effects.



The following art filters are available:

Art Filters
Pop Art, Soft Focus, Pale&Light Color, Light Tone, Grainy Film, Pin Hole, Diorama, Cross Process, Gentle Sepia, Dramatic Tone, Key Line, Watercolor, Vintage, Partial Color, Bleach Bypass, Instant Film

Some art filters have altered versions of the original art filter. (e.g. Pop Art I/II, Pin Hole I/II/III) Color Filter and Monochrome Color options are available with some art filters.

In Pop Art I and Soft Focus, you can adjust the color filter by moving the slider on the monitor up and down.

P (Program mode)
The camera automatically adjusts the settings best suited for the scene. Camera menu settings such as white balance and exposure compensation can be changed.
Refer to the following question for more information:
What differentiates the AUTO mode from P (Program shooting) mode?

A (Aperture Priority mode)
When the aperture value (F-number) is set manually, the camera sets the appropriate shutter speed automatically.
If a smaller aperture (F-number) is set, the focus range becomes narrower. You will get pictures of a subject with out-of-focus background. If a larger aperture (F-number) is set, the focus range becomes wider. Both the subject and the background come into focus.

S (Shutter Priority mode)
When the shutter speed is set manually, the camera sets the appropriate aperture automatically.
A fast shutter speed can freeze a fast-moving action without blurring. A slow shutter speed will blur a fast-moving action. This blurring will give the impression of dynamic motion.

M (Manual mode)
Both the aperture and the shutter speed can be set manually. You can also set the BULB (Bulb photography), LIVE TIME (Time photography) or LIVECOMP (Live composite photography).

(Movie mode)
This mode enables you to create movies. In addition to standard movies, you can shoot 4K movies (in 4K mode) or slow motion movies (in High-speed mode).

Movie modes	Description
4K	Shoot 4K movies.
Standard	Shoot standard movies.
High-speed	Record slow-motion movies. Sound is not recorded.

Question :
Question: What differentiates the AUTO mode from P (Program shooting) mode?

Answer:

The followings describes the differences:

In AUTO mode, the camera determines the appropriate settings for the shooting conditions and subjects.
The camera automatically sets to the best suited shooting mode such as Landscape, Portrait, Portrait + Nightscape or Macro. AUTO mode is convenient for beginners.

Camera settings cannot be changed, except some menu options, because this is a fully automatic mode. Use the Live Guide to easily adjust color, brightness and background blurring.



P mode is for program shooting. The camera automatically sets the optimum aperture and shutter speed based on the lighting conditions. Shooting settings such as exposure compensation, white balance and sequential shooting can be changed.

After getting used to shooting with the camera using the AUTO mode, SCN mode or AP mode, we recommend you to use the P mode for changing to the desired settings manually.

Question :
What kinds of SCN (Scene) modes are available?

Answer:

In SCN (Scene) mode, you can shoot in an appropriate setting by selecting a subject or shooting scene. Set the mode dial to SCN, and then select a sub mode from 22 modes.



When the mode dial is already set to SCN (Scene) mode, press the button to select other sub modes.

Question :
What kinds of AP modes are available?


Answer:

AP (Advanced Photo) mode enables you to shoot in advanced settings like Live Composite and Multiple Exposure with a simple operation.



While SCN modes such as Silent, Panorama and Light Trails achieve effects that are similar to the Live Composite in AP mode, more advanced settings are possible in AP mode than in SCN mode.
When the mode dial is already set to AP mode, press the (Shortcut) button to select other modes.

AP mode	Description
Live Composite	For recording light trails of stars and other objects while keeping the overall exposure constant. The results of each moment can be checked on the monitor while shooting. Picture mode and White Balance can be changed, which is not possible in the SCN mode Light Trails. It is recommended to stabilize the camera using a tripod to prevent camera shake and to shoot with remote control using the wireless remote mode via OI.Share. The maximum recording time for one file is approximately 3 hours. Advanced settings can be configured via Live Composite (LIVECOMP.) in M mode.
Live Time	For recording pictures in long time exposures without pressing the shutter button. The results of each moment can be checked on the monitor while shooting. The recording stops when you press the shutter button again or when the set time has elapsed. It is recommended to stabilize the camera using a tripod to prevent camera shake and to shoot with remote control using the wireless remote mode via OI.Share. Advanced settings can be configured via BULB / TIME in M mode.
Multiple Exposure	Combines two different images into a single shot. After taking the first image by depressing the shutter button, the first image is displayed translucently on the monitor, so the second shot can be composed using the first image as a guide. Advanced settings can be configured via Multiple Exposure in P / A / S / M mode.
HDR	Captures details in both bright highlights and deep shadow areas. A series of four shots with different exposure are captured and combined into a single image. Noise may be noticeable when taking photos in conditions where the shutter speed becomes slow. For best results, stabilize the camera using a tripod.
Silent	Disables camera sounds and lights in situations in which they may be unwelcome. Electronic shutter is enabled in this mode. Note that due to the electronic shutter, the desired results may not be achieved under flickering light sources such as fluorescent or LED lamps or if the subject moves abruptly during shooting. The subject may appear to be distorted in photographs if camera moves quickly during shooting or when shooting fast-moving subjects. Advanced settings can be configured via Silent in P / A / S / M / ART mode.
Panorama	Takes a series of shots that are joined together to create a wide-angle photo (Panorama photo) only by following an on-screen guide. Choose from two angles of view: a wider angle than normal shots ( ), or an even wider angle ( ). • Shooting may be cancelled and an error displayed if: the camera is panned too slowly or too quickly / the camera is panned diagonally / the camera is panned in the opposite direction to the arrow in the display / the lens is zoomed in or out / panning does not start within a set period
Keystone Compensation	Correct the effects of perspective in photos of buildings or landscapes. You can correct the image using the control dial (Up, Down, Right, Left button) while looking at the image on the monitor.
AE Bracketing	Each time the shutter button is pressed, the camera takes a series of photos, varying exposure with each frame. 3 or 5 frames are taken once the shutter button is depressed. 3f (3 frames): Takes 3 frames. The first at ±0.0 EV (optimal exposure), the second at -1.0 EV and the third at +1.0 EV. 5f (5 frames): Takes 5 frames. The first at ±0.0 EV (optimal exposure), the second at -1.3 EV, the third at -0.7 EV, the fourth at +0.7 EV and the fifth at +1.3 EV.
Focus Bracketing	Each time the shutter button is pressed, the camera takes a series of eight photos, varying the focus distance with each shot. The camera takes pictures at the focus distance that is secured by pressing the shutter button halfway down, and at slightly different points shifting the focus from the foreground to the background. You can choose the amount of focus distance changes from two modes: (changes by a large amount) and (changes by a small amount).
