There are several flash modes on the IDs Mark III that apply to Canon Speedlites. Of course, there's a whole universe of flash and strobe lighting to be addressed later. For now, let's look at the Canon flash modes.
The IDs Mark III uses Canon's latest flash technology, known as E-TTL II Autoflash. It's a welcome improvement over the former version, called E-TTL, which needed a pre-flash to attain exposure. The E-TTL II system also uses improved lens focusing distance data to adjust its setting.
Because I and many others often use various modifiers over Speedlites to soften their look, there's a bit of trial and error to figure out how to adjust flash exposure to work for you. Being able to see the image immediately on the rear LCD is a huge advantage in this area, as compared to shooting with film cameras and backs, where the only way to have any idea of lighting was to shoot expensive, harsh, and contrasty Polaroids, and then wait two minutes for them to develop.
Following are various ways you can set the camera to expose while using Speedlites.
♦ Evaluative. The E-TTL II system reads the flash in the same way the camera reads Evaluative exposure in continuous-light conditions.
♦ Average. The E-TTL II system takes an average reading, similar to Average exposure when metering in continuous-lighting environments.
