Tips & Tricks:

  • Bounce Flash: Using a direct flash on your subject with the Lytro Illum risks flattening your image out, effectively reducing the amount of captured depth information.  To avoid this, whenever possible try bouncing the light for indirect supplementary lighting.  By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject.  This can soften shadows behind the subject for a more natural-looking shot.  A white wall is best for reflectivity, while a colored wall can provide a colored cast effect.
  • Catchlight:  Catchlights are useful for illuminating in a subject’s eyes and adding supplementary light to facial features.  The Lytro TTL Flash has a built-in catchlight panel that can be pulled out from the head of the flash.  For maximum catchlight effect be within 1.5m/4.9ft of the subject.
  • Diffusion: Using direct flash exposure can reduce depth, wash out subjects, create hard shadows, and illuminate a background in ways that differ from the photographer’s creative intent.  By using diffusion on your flash the result will be images that are more visually appealing through the use of softer lighting.  The Lytro TTL flash includes a diffuser accessory, but any material that alters the way lighting hits a subject could be considered diffusion.  For an even more intense visual change, colored diffusion can alter the entire look of an image.
  • Stroboscopic Flash: By firing a rapid series of flashes, users can capture a sequence of images with a moving subject in a single photograph.  The Lytro TTL Flash allows complete control of number of flashes, firing frequency, and output power.

FAQs:

  • Does the on-camera flash compensation menu control all modes on the Lytro TTL Flash?
    • No, adjustments to the on-camera flash compensation menu have no effect on flash functionality when the flash is set to Manual or Repeat mode.
  • Can the Lytro TTL Flash be used in a Master/Slave configuration?
    • Yes.  Slaves can be programmed into 3 different groups that each have 4 channels.  This allows users to program up to 12 custom settings amongst their slaves.
  • How long will the flash idle for before going into power saving mode?
    • Approximately 4 minutes (or 60 seconds if the Sleep custom function is turned on)
  • How many times can the Lytro TTL Flash fire before replacement batteries are needed?
    • Battery life is rated for 100-700 flashes, depending on consecutive flash usage and intensity.
  • Can rechargable AA batteries be used?
    • While they can be used, we do not recommend rechargeable batteries.  In our tests, rechargeable batteries can be problematic for wireless connectivity, and users may experience decreased range/strength of the flash's wireless signal.  For these reasons, we recommend Alkaline AA batteries
  • I’m having problems using wireless mode in bright outdoor situations, why is this happening?
    • Because wireless connectivity is IR based and sunlight can interfere with the signal, wireless mode can be less effective in outdoor situations with bright sunlight.
  • Can I use CP-E4 compatible third party battery packs that are not manufactured by Canon?
    • No.  Only CP-E4 battery packs manufactured by Canon will work with this flash.  We have found that using other third party battery packs will result in the flash being unable to turn on.
  • Why does the focal length of my camera not match the focal length setting on my Lytro TTL flash?
    • The Lytro TTL flash's zoom tracking is much less granular than the zoom ring on the Lytro Illum. It has a limited number of steps and chooses the next lowest step compared to the focal length. Example: the flash has steps at 105 mm and 120 mm. It cannot track between those values, so if you are increasing the focal length on the camera's zoom ring, the flash will stay at the 105 mm step until you move past 120 mm.
  • When my Lytro TTL flash's diffuser is active the focal distance on the flash is locked at 14mm, is this normal?
    • Yes, the flash should be locked at 14mm when the diffuser is engaged.
  • The focal distance on my flash is stopping at 135mm even when my camera is fully zoomed at 250mm, is this normal?
    • Yes, 135mm is the limit for focal length on the Lytro TTL flash.
  • When using the flash my ISO is always locked at 80, why can't I change it?
    • While using the flash in 'Program' or 'Shutter Priority' modes the ISO is locked at 80. If you are in 'Manual' or 'ISO Priority' you can select the ISO yourself.
