    Getting Started with Macro Flash Photography This chapter describes the preparations before starting macro flash photography and the basic shooting operations. Cautions for firing continuous flash To avoid degrading and damaging the flash unit due to overheating, limit the continuous firing at full output to 20 times or less.

  • Page 18: Installing The Batteries

    Normal Flash Approx. 0.1-3.3 seconds Approx. 0.1 - 5.5 seconds Approx. 100 - 700 times Based on new AA/LR6 alkaline batteries, both-sides firing, and Canon’s testing standards. The Quick flash function enables flash photography before the flash is fully charged (p.27).
  • Page 19 Installing the Batteries CAUTION Do not use “AA/R6 lithium batteries”. Note that certain “AA/R6 lithium batteries” may become extremely hot in rare cases during use. Due to safety reasons, do not use “AA/R6 lithium batteries”. When performing continuous flash, do not touch the flash unit, batteries, or the area near the battery compartment.

  • Page 30: A: Fully Automatic Flash Photography

    a: Fully Automatic Flash Photography When you set the camera’s shooting mode to <d> (Program AE) or fully automatic mode, you can shoot in E-TTL II/E-TTL fully automatic flash mode. Set the flash mode to <a>. Press the <E> button. Turn <9>, select <Q>, then press <8>.
  • Page 31 a: Fully Automatic Flash Photography If the flash exposure confirmation lamp does not light or if the subject is dark (underexposed) when you check the shot image, move closer to the subject and shoot again. You can also increase the ISO speed when using a digital camera.

  • Page 32: E-Ttl Ii/E-Ttl Autoflash By Shooting Mode

    E-TTL II/E-TTL Autoflash by Shooting Mode Simply by setting the camera’s shooting mode to <f> (aperture- priority AE) or <a> (manual exposure), you can execute macro flash photography using E-TTL II/E-TTL autoflash. You can perform flash photography while obtaining a standard exposure of both the main subject and background while considering the depth of field.

  • Page 33: Focusing Lamp

    E-TTL II/E-TTL Autoflash by Shooting Mode Focusing Lamp Press the <d> button to light the focusing lamp for 20 sec., making focusing easier. Press the button again to turn off the lamp. The focusing lamp turns off automatically when you press the shutter button on the camera completely.

  • Page 34: Modeling Flash

    E-TTL II/E-TTL Autoflash by Shooting Mode Modeling Flash When the camera’s depth-of-field preview button is pressed, the flash fires continuously for approx. 1 sec. This feature is called “modeling flash”. This is effective for checking shadows cast on the subject and the lighting balance.

  • Page 35: Effective Flash Metering Range

    Effective Flash Metering Range The MT-26EX-RT’s effective flash metering range largely varies depending on the flash heads’ position.

  • Page 36: D Combined Use With The Diffuser Adapter

    D Combined Use with the Diffuser Adapter If you shoot with the provided diffuser adapter attached to the flash heads, you can spread the flash light across a large area and suppress the shadows on the subject. Attach the diffuser adapter. Attach the diffuser adapter securely to a flash head until it clicks in place, as shown.

  • Page 37: Flash Exposure

    D Combined Use with the Diffuser Adapter When the diffuser adapter is attached, the effective flash metering range changes. Take necessary countermeasures such as adjusting the ISO speed on the camera or applying flash exposure compensation (p.40) as necessary. When Quick flash (p.27) is fired with the diffuser adapter attached, taking the picture after the flash-ready lamp is lit in red is recommended since the flash output may not be sufficient.
