Capture modes

  • PHOTO
    Capture a single or a series of photos in JPG, TIFF or DNG format (including auto-development of DNG to JPG and TIFF). The Photo capture mode supports multiple photo resolutions and aspect ratios. For the auto-developed DNG there is a list of settings that are used to generate JPG or TIFF and include noise reduction, sharpening, shadows and more. The DNG (and auto-developed DNG) capture supported only on iPhone SE/6S/7/Plus
  • VIDEO
    Capture a video with up to 240 frames per second (device dependent). The maximum video resolution depends on the device or camera used (front/back) and can be as high as 4K+ for back camera and up to 3K for a front camera. The video can be saved using MOV or MP4 file formats with a selectable video and audio bit rates (low, medium, high, max presets)
  • BURST
    Capture a series of images in quick succession using JPG or DNG (iPhone SE/6S/7/Plus) image file formats. The Burst capture mode supports multiple image resolutions when JPG file format is selected or maximal if DNG file format is used. 
  • BRACKETING
    Capture a series of images with different exposure using JPG or DNG (iPhone SE/6S/7/Plus) image file formats. The Bracketing capture mode supports a capture of up to 15 images in a single bracket with adjustable EV step as low as 0.1 F-stop. Auto exposure, ISO or shutter speed brackets can be selected. 
  • TIME-LAPSE
    Capture a series of images with a lapse between them and save it as a video. The output frame rate of the output video can be as high as 60 frames per second and resolution as high as 4K+ (depends on device and camera used). The Time-lapse capture mode supports adjustable lapse between images and the output video bit rate.
  • MULTI-SHOT
    Capture an image that is a combination of multiple photos combined using a different mathematical algorithms to achieve a certain effect. The Multi-shot capture mode currently supports
    • Slow shutter - for noise free images if scene is static or motion blur if a scene is dynamic. This sub-mode is great for low noise static night scenes or "smooth water" during daylight
    • Light painting - to create a "light trails" effect 
    • Long exposure - to simulate a long exposure, longer than supported by the device

Global settings

  • SUPPORT
    • Contact us
      Allows to write an email to support without leaving the app
    • Rate the app
      Opens the app's App Store page where one can rate the app. Please, if you like the app, let others know about it!
  • GENERAL
    • Language
      Allows to select the app's language. By default the CameraPixels will use a system default language if it's supported by the app or English otherwise. Once another language is selected, the app has to be restarted for changes to take effect
    • Grid
      A helper grid on a screen helping properly frame the scene. Currently the following grids are supported: Thirds (rule of thirds), Grid (with symmetry markers), Golden ratio and Phi
    • Histogram
      Shows a live histogram or a over/under-exposed indicator. The over/under-exposed indicator helps easily identify if a final image will be over or under-exposed with a current manual settings (ISO and shutter speed). The live histogram shows a luminance histogram of the image
    • Horizon levels
      Activates a 3D tiltimeter that helps to align the horizon and vertical inclination
    • Geotagging
      Activates location services that allow to tag photos and videos with a geo tags. Please note, location services drain you phone's battery faster when activated
    • Fullscreen viewfinder
      When activated allows the viewfinder to fill the whole screen when output photo aspect ratio is equal to your phone aspect ratio (for example iPhone 7/Plus it's 16:9 aspect ratio). When the option is deactivated, the viewfinder is fit between top and bottom toolbars
    • Light theme
      When active, removes toolbars background, leaving only small rounded square backgrounds  for each icon. The theme is mostly useful for smaller diagonal phones, like iPhone SE
    • Remember capture mode
      When active saves the last used capture mode. When the app is re-launched, the last used capture mode is activated automatically. When this option is deactivated (default), the app always starts in Photo capture mode using a rear camera unit
    • Remember capture settings
      When active, the last capture settings of each capture mode are saved. When app is re-launched, all capture modes restore their last used settings automatically. Together with the active "Remember capture mode", this setting allows to re-launch the app in exactly same state as it was before closing
    • Volume button to capture
      When active allows to use volume down button to capture a photo or start/stop video recording. Many selfie sticks can be supported by activating a given setting
    • ProView mode
      When active (by default) the manual settings toolbar is always visible on screen. 
  • PHOTO AND VIDEO
    • Slow motion playback
      The speed of the high frame rate video playback. The videos are saved with the original fps setting (120 or 240 fps), but can be played within the app using a standard playback speeds like 24, 30 or 60 fps. For example, the video recorded at 240 fps and played at 24 fps will be 10x slower
    • Min EV step
      The setting specifies EV precision to be used in Bracketing capture mode to select EV step between exposures in a bracket
  • TIME LAPSE AND IMAGE SERIES
    • Screen brightness
      Sets the screen brightness when app is recording a time-lapse video or image series. Reducing the screen brightness during lengthy recordings preserves phone's battery charge better
    • AF/AE auto lock
      When active, automatically locks focus and exposure during the time-lapse video or image series recordings

Auto focus and auto exposure interactions

CHANGE FOCUS AND EXPOSURE POINTS

Use a single tap on screen to change the focus and exposure points. By default, focus and exposure are measured in the same point, therefore taping on screen with a single finger will update both of them simultaneously. While not locked, the focus and exposure are updated automatically when changes in scene are detected

SEPARATE FOCUS AND EXPOSURE POINTS

Tap with two fingers on a screen or the "+" icon at the right bottom part of the focus area to separate focus and exposure points. Once separated, focus and exposure points could be adjusted on screen independently by dragging the corresponding area. While not locked, the focus and exposure are updated automatically when changes in scene are detected

LOCK FOCUS AND/OR EXPOSURE

Use press-and-hold gesture within the focus or exposure or a small lock icon at the top left/right sides of exposure/focus areas to lock or unlock them. The locked focus or exposure are not updated automatically when changes in the scene are detected. The update can still be triggered by manually dragging the area around the screen

RESET FOCUS AND EXPOSURE

Use double tap on screen with a single finger to reset location and lock status of focus and exposure points. After the reset, focus and exposure are moved to the center of screen and unlocked. Exposure metering mode is switched from "spot" to "center weighted"

Manual adjustments

MANUAL ISO AND SHUTTER SPEED

In order to manually adjust ISO and/or shutter speed tap on the corresponding button first. Once the setting is switched to a manual mode, the border around its icon will be highlighted. The CameraPixels supports 4 exposure modes:  AUTO - ISO and shutter speed are adjusted by the app automatically, MANUAL - ISO and shutter speed are manually adjusted by the user, ISO PRIORITY - ISO is manually adjusted by the user, while shutter speed is automatically adjusted by the app, SHUTTER PRIORITY - shutter speed is manually adjusted by the user, while ISO is automatically adjusted by the app.  To reset ISO and/or shutter speed back to AUTO mode press the button on the right side of value selector

ADJUSTING EV COMPENSATION

EV compensation can be adjusted when CameraPixels is in AUTO, ISO PRIORITY or SHUTTER PRIORITY exposure modes only. When the EV compensation is adjustable, it's always in manual mode (icon border highlighted).  In order to reset the EV compensation back to 0.0 press the button on the right side of value selector

MANUAL WHITE BALANCE

CameraPixels supports manual adjustment of the white balance (color temperature and tint). Once the white balance was switched to manual mode, color temperate and tint can be adjusted using a value selector (switch between temperature and tint using a left button on the value selector toolbar). There are also several presets that can be used to quickly set white balance value in some common situations. The following presets are available: AWB - auto white balance, Grey card - white balance is adjusted using a grey card method (place card in front of the camera before selecting this preset), Shadows - 7000K, Cloudy - 6000K, Flash - 5500K, Daylight - 5200K, Fluorescent - 4000K and Tungsten - 3200K

MANUAL FOCUS

CameraPixels allows manual adjustment of the focus from camera supported minimum (for closeups) to its maximum (landscapes, etc.). When you start manually adjusting the focus using a value selector, CameraPixels automatically zooms in to allow better precision. The manual focus is very useful for closeup captures (especially in poor lighting) when  auto focus algorithm may fail to lock. To reset focus to auto mode press the button on the right side of value selector

USEFUL SHORTCUTS:

  • LONG PRESS ON EV SETTING BUTTON - quickly resets ISO and shutter speed settings to auto mode
  • LONG PRESS ON WB SETTING BUTTON - quickly locks white balance using a grey card (place the card in front of the camera before long press)
  • SWIPE UP - on any adjustment setting to reset it

Additional settings

Each capture mode has a set of additional settings that can be adjusted for the desired output result. In some capture modes like Photo, the list of additional settings also depends on the selected output file type. The flash/torch status, output file format and lens (wide/tele - only  iPhone 7 Plus) are adjustable using the top toolbar. When torch is activated (available in all capture modes), an additional slider appears on the screen, which can be used to adjust torch brightness from 0% (off) to 100% (maximum brightness)

PHOTO

SIZE:

* Resolution: selects the output photo resolution. The ISO and shutter speed ranges are dependent on output resolution and for some selections can be smaller than when a maximum resolution is selected.

* Crop: sets the output photo aspect ratio. The original photo usually is cropped to fit inside selected aspect ratio rectangle. CameraPixels supports 16:9, 4:3, 3:2, 1:1, 1.16:1, 2:1, 7:6, 5:4 aspect ratios

* Quality: sets the output JPG quality (or selected the TIFF compression method). The JPG qualities from 60% to 100% (inclusive) use YCrCb 4:2:0 format, while MAX quality produces JPG images with YCrCb 4:4:4 format

* Stabilisation: activates or deactivates the optical/digital stabilisation. On devices with optical stabilisation, both digital and optical stabilisations turned OFF or ON together. The activated stabilisation usually adds some latency to capture of the photo and therefore it's advisable to disable it for captures with a tripod

* Night mode:  when active allows the camera to automatically select the slowest possible shutter speed in auto exposure mode. By default, the camera uses ISO increase in low light situation to adjust the exposure. When the Night mode is active, it's advisable to use a tripod for blur-free photos

 

INTERVALOMETER: 

* Timer:  allows to postpone the capture of the first photo
* Image count,  Lapse between images: together control the capture of series of images. Image count value BULB activate infinite capture mode, when capture can be stopped only manually. Use series captures when you want to create manual time-lapse
