75TTL function – 503CW / 503CWDThe reflective characteristics of the digital sensor are different to film surface characteristicsfor which the TTL function was originally designed. However, by changing (in effect, ‘trick-ing’) the setting, TTL exposures can be made. Proceed as follows:Move the ISO selector on the camera so that is becomes approximately 12⁄3 f/stop higherthan the ISO setting on the digital capture unit. Therefore, for example, when the back isset at 50 ISO, the ‘film speed setting’ on the camera should read 160 ISO, and so on. Testingfor the most suitable compensation that suits you is recommended.Studio flash/strobe units when tethered to a desktop computerIf the 503CWD/CFV is tethered to a computer that is connected to a regular electricity sup-ply system as well as a studio flash/strobe unit that is also connected to a regular electricitysupply system/generator system, then make the following connections instead. For yourown safety and to protect the electronics in the digital capture unit, please ensure you dothis correctly.a) Connect the flash input sync cable from the sync contact (PC connector) on the lensto the flash sync IN terminal on the back.b) Connect the flash output sync cable from the flash sync OUT terminal on the back toa regular flash/strobe sync cable that is connected to the unit.Portable unitsAll 500 series and SWC series cameras use the regular PC contact on the lens for flash sync.200 series models, FlexBody and view cameras require other configurations (see chart).Most flash/strobe units are suitable for use with the 503CW/503CWD/CFV, with some combinationsoffering TTL. Check the chart further on in this chapter to find the specific combination you intendto use.Pay particular attention when using studio flash/strobe units and tethered to a stationary computeras this cable configuration guards against both personal injury and damage to equipment.13Flash / StrobeViewfinder indicator – 503CW / 503CWDFlash/strobe operation and flash battery–check are indicated by a red light, located underthe left edge of the focusing screen. It is operative only when a dedicated flash/strobe isconnected to the TTL socket. It indicates three separate states as described below.
