Use of "Flash" and "Strobe"

The Hasselblad has built-in circuits for both flash and strobe lights. Connections are made with an attachment that fits into the bracket on the side of the camera, or with the base of the frame-finder. When inserting these attach-

ments, be sure that they are pushed in until they click into place. Otherwise, no contact will be made.
If the regular attachment is used, the words "Flash" and "Strobe" should be uppermost.
If the frame-finder is used, the contacts should point down.

"Flash"

Always connect the cord to the "Flash" contacts. Be sure that your flash gun is insulated from contact with the camera or a short circuit will be created that will fire the bulbs. Always use focal plane type bulbs. Since these have different delays, adjust the synchronization accordingly.

The table on the following page gives data for most standard bulbs. If yours is not given, use the following procedure:
If the negative should be less exposed on that side, where the two small notches are, in relation to the opposite side, the pointer should be moved in direction to higher number. If contrary exposed negatives, the pointer should

be moved in the direction to lower number. Always make adjustments of pointer from a lower number and up.

Be sure to use the proper contacts - flash for flash, strobe for strobe.

"Strobe"

Use the "Strobe" contacts. Since strobe light is so fast, the shutter must be fully opened, otherwise only a portion of the film will be exposed. Therefore, shoot at 1/25, or slower.
For strobe lights with delay (the above applies to those without) do not use a speed faster than 1/10 of a second. If you do, or use the

flash contacts at faster speeds, only a portion of the film will be exposed.

Be sure to use the proper contacts - flash for flash, strobe for strobe.
