For Type-A Cameras Basic Flash Photography When the Speedlite 550EX is attached to a Type-A camera such as the EOS 3, you can take flash pictures with E-TTL autoflash as easily as normal autoexposure (AE) pictures. As with evaluative metering, the E-TTL autoflash system uses a multi-zone sensor. A preflash is fired for evaluative flash metering and the reading is stored in memory. Since E-TTL autoflash is linked to the active focusing poin the flash exposure is highly accurate.
1. Using Flash in Full Auto Mode Set the camera’s picture-taking mode to P (Program AE) or □ (Full Auto). Flash photography will then be as easy as normal AE photography. The camera sets the aperture and shutter speed automatically to suit a wide variety of lighting conditions including outdoor fill flash. The E-TTL autoflash system sets the flash exposure automatically. H Set the camera’s picture-taking mode ' toP. ETTL Cn Zoom jumm O Set the 550EX’s flash mode to ^ ETTL 0 Focus the subject.
Using Flash in Full Auto Mode After the flash fires, check that the flash exposure confirmation lamp lights. When a correct flash exposure has been obtained, the flash exposure confirmation lamp lights for about 3 sec. If the lamp does not light, the flash may have been insufficient, resulting in underexposure. In such a case, check that the pilot lamp is red, then move closer to the subject and take the picture again.
2. Using Flash in Other Camera Modes Flash photography is also automatic in the other picture-taking modes. In th Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the E-TTL autoflash system sets the flash exposure automatically. The camera sets the necessary shutter speed (in the Av mode), aperture (in the Tv mod or flash output (in the M mode). Flash photography is as easy as normal AE picture-taking.
Using Flash in Other Camera Modes (1) Av: Aperture-Priority AE and E-TTL Autoflash This mode is effective for controiiing the depth of field in your fiash pictures. You can also obtain a balanced exposure between the subject and background. You set the aperture and the camera sets the shutter speed automatically to obtain a correct exposure for the background. The E-TTL autoflash system obtains the proper exposure based on the aperture you set. H Set the camera's picture-taking mode * to Av.
Using Flash in Other Camera Modes • Balanced Flash Exposures In low-light situations, the exposure level can be balanced between the subject and background by using a slow sync speed. You can obtain balanced flash exposures automatically by setting the camera’s picture-tak mode to Av. The camera then sets the sync speed automatically to suit the background. Using a tripod is recommended to prevent camera shake. Balanced flash exposure. Flash exposure In the Full Auto mode.
Using Flash in Other Camera Modes (2) Tv: Shutter Speed-Priority AE and E-TTL Autoflash By selecting the shutter speed, you can obtain various effects with flash. You can set the shutter speed from 30 sec. to the top sync speed. The camera then sets the aperture automatically to obtain a correct exposure for the background. The E-TTL autoflash system controls the flash exposure based on the camera-selected aperture.
Using Flash in Other Camera Modes (3) M: Manual Exposure and E-TTL Autoflash In this mode, you set both the shutter speed and aperture. The E-TTL autoflash system controls the flash exposure based on the the aperture yo set. H Set the camera’s picture-taking mode ’ to M and set the desired aperture and shutter speed anywhere from 30 sec. to the top sync speed. You can also use buLb.

With high-speed sync, the Guide No. changes depending on the shutter speed (see page 121). The faster the shutter speed, the shorter the flash range will be.
2. FE Lock You can use FE (flash exposure) lock with Type-A cameras. This is the flas version of AE lock. With FE lock, you use spot metering to obtain the corre flash exposure reading for a specific part of the subject. • FE lock works with E-TTL and high-speed sync (FP flash) H Select a picture-taking mode with the ’ camera. 2 Focus the subject. 3 Aim the viewfinder’s spot metering circle over the part of the subject to be metered. Then press the button on the camera.
FE Lock Check the flash exposure level in the viewfinder, then take the picture. * so For this shot, FE lock was used for the subject’s face before the picture was recomposed. FE lock prevented the wall’s bright reflection from throwing off the exposure. The subject was thus correctly exposed. If the subject is too far away to obtain a correct flash exposure, i will blink In the viewfinder. Either move closer to the subject or use a larger aperture (smaller fnumber) and try again.
3. Flash Exposure Compensation Flash exposure compensation with the 550EX can be set up to ±3 stops in 1/3-stop increments (or 1/2-stop increments with some cameras). You can also use flash exposure compensation in combination with normal exposur compensation (to control the background’s exposure level) in a flash picture H Press the < SEL/SET > button and Zoom SOfnm I 0S071152 3 4 6 * select S.

With bounce flash. Without bounce flash. Bounce the flash on a plain, while, reflective surface II a colored surface is used, the picture may have a color cast.
Bounce Flash • Creating a Catchlight A catchlight is a reflection of the flash in the subject’s eyes. A catchlight in the eyes makes the subject look more lively. For portraits, you can easily create a catchlight with the 550EX. Tilt the flash head upward all the way by 90°. Extend the built-in wide panel until it clicks in place as shown in the figure. To take a picture, follow the same procedure in "5. Bounce Flash." 41 41 42 Turning the flash head left or right will not produce a catchlight.
6. Close-Distance Flash Photography The flash head can be tilted downward by 1°. This position enables the flash to better illuminate the lower part of a subject that is close to the camera.

Q.
8. Stroboscopic Flash With stroboscopic flash, a rapid series of flashes is fired. It can be used to record multiple images of a moving subject in a single photograph for later study. You can set the firing frequency (the number of fiashes per sec. expressed Hz) from 1 Hz to 199 Hz. The firing frequency can be set in 1-Hz incremen from 1 Hz to 20 Hz, in 5-Hz increments from 25 Hz to 50 Hz, and in 10-Hz increments from 60 Hz to 199 Hz. Up to 100 flashes can be fired continuously.

9. Second-Curtain Synchronization Normally, the flash fires in synchronization with the first shutter curtain when the shutter is fully open. With second-curtain synchronization, the flash fires immediately before the second shutter curtain closes at the end of the exposure. With second-curtain synchronization and a slow shutter speed, you can create a trailing blur (illuminated by ambient light) that trails a moving subject (illuminated by the flash) to give a natural-looking illusion of motion.
10. Modeling Flash When the 550EX is used with the EOS-3, a modeling flash can be fired so you can check the lighting and shadow effects before you take the picture. Set the desired flash photography settings with the camera and 550EX. Press the camera’s depth-of-field preview button. * The aperture will stop down. • The 550EX will fire a series of flashes at 70 Hz for 1 sec. Custom Function CF-6 can disable the modeling flash and prevent It from firing. See page 113.
For Type-A Cameras Wireless Flash Photography This section covers wireless flash photography with the 550EX. It explains the 550EX’s built-in master and slave flash features, 550EX Wireless Flash Features • A wireless flash system with multiple Speedlite 550EXs can be used as easily as a single, on-camera Speedlite 550EX. • Up to three 550EXs or three groups of 550EXs can be set as slave units for automatic control. • 550EXS set as slave units can be positioned to obtain the desired lighting effects.
[1] Wireless System Setup and Testing The wireless flash system can be setup in one of two ways: @ With a 550EX set as the master unit and one or more 550EXs set as slave units. (D With Speedlite Transmitter ST-E2 (sold separately) used as the master unit and one or more 550EXs set as slave units. This section describes the procedure for the former. For the latter, refer to the Instructions for Speedlite Transmitter ST-E2. 1.
2. Setting the 550EX as a Slave Unit Set the wireless selector to SLAVE on the 550EX to be used as a slave unit.

• Speedlite Transmitter ST-E2 (Sold separately) Speedlite Transmitter ST-E2 serves as the master unit for wireless Speedli 550EX control. It can control up to two slave unit groups (A and B). It is attached directly to the camera’s hot shoe. As a master unit, the differences between the 550EX and Speedlite Transmitter ST-E2 are listed below.
For Type-B Cameras Basic Flash Photography When the Speedlite 550EX is attached to a Type-B camera such as the EOS1N, you can take flash pictures with TTL autoflash as easily as normal autoexposure (AE) pictures. Flash photography can be fully automafic—all you do is press the shutter button. Or you can set the desired shutter speed and aperture and still obtain autoflash exposure.
1. Using Flash in Full Auto Mode Set the camera’s picture-taking mode to P (Program AE) or □ (Full Auto). Flash photography will then be as easy as normal AE photography. The camera sets the aperture and shutter speed automatically to suit a wide variety of lighting conditions including outdoor fill flash. The E-TTL autoflash system sets the flash exposure automatically. ■i Set the camera’s picture-taking mode ' toP. O Set the 550EX’s flash mode to TTL Zoom 5umm ^ TTL 0 Focus the subject. 0,5 0.7 1 1.
Using Flash in Full Auto Mode After the flash fires, check that the flash exposure confirmation lamp lights. When a correct flash exposure has been obtained, the flash exposure confirmation lamp lights for about 3 sec. If the lamp does not light, the flash may have been insufficient, resulting in underexposure. In such a case, check that the pilot lamp is red, then move closer to the subject and take the picture again. Fill Flash Fill flash can be used outdoors in daylight to supplement existing light.
2. Using Flash in Other Camera Modes Flash photography is also automatic in the other picture-taking modes. In th Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the TTL autoflash system sets the flash exposure automatically. The camera s the necessary shutter speed (in the Av mode), aperture (in the Tv mode), o flash output (in the M mode). Flash photography is as easy as normal AE picture-taking.
Using Flash in Other Camera Modes (1) Av: Aperture-Priority AE and TTL Autofiash This mode is effective for controlling the depth of field in your flash pictures. You can also obtain a balanced exposure between the subject and background. You set the aperture and the camera sets the shutter speed automatically to obtain a correct exposure for the background. The TTL autoflash system obtains the proper exposure based on the aperture you set. H Set the camera’s picture-taking mode * to Av.
Using Flash in Other Camera Modes • Balanced Flash Exposures In low-light situations, the exposure level can be balanced between the subject and background by using a slow sync speed. You can obtain balanced flash exposures automatically by setting the camera’s picture-tak mode to Av. The camera then sets the sync speed automatically to suit the background. Using a tripod is recommended to prevent camera shake. Balanced flash exposure. Flash exposure in the Full Auto mode.
Using Flash in Other Camera Modes (2) Tv: Shutter Speed-Priority AE and TTL Autofiash By selecting the shutter speed, you can obtain various effects with flash. You can set the shutter speed from 30 sec. to the top sync speed. The camera then sets the aperture automatically to obtain a correct exposure for the background. The TTL autoflash system controls the flash exposure based on the camera-selected aperture.
Using Flash in Other Camera Modes (3) M: Manual Exposure and TTL Autoflash In this mode, you set both the shutter speed and aperture. The TTL autoflas system controls the flash exposure based on the aperture you set. camera’s picture-taking mode 1 toSetMthe and set the desired aperture and shutter speed anywhere from 30 sec. to the top sync speed. You can also use buLb. the 550EX's flash mode to 2 Set TTL. Focus the subject. 3 OJ 0.
