Claims
- 1. A flash device, comprising:
- (a) a combination of pre-flashing means and main flashing means disposed in front of a flash device body;
- (b) a light sensitive element arranged to receive a reflection light which results from flashing by said flashing means and comes from an object to be photographed; and
- (c) a panel arranged in front of the flash device body to define the projection light characteristics of flash lights projected from said pre- and main flashing means to the object, said panel being slidable relative to the front of the flash device body and said projection light characteristics of said pre-flashing means and said main flashing means being arranged to be variable with the slided position of said panel simultaneously and in the same manner.
- 2. A flash device comprising:
- (a) main flashing means for generating flash for exposure;
- (b) pre-flashing means for effecting a flash before an exposure; and
- (c) irradiation angle regulating means for matching the irradiation angle characteristic of the light emitted by said main flashing means onto an object and the irradiation angle characteristic of the light emitted by said pre-flashing means.
- 3. A flash device according to claim 2, in which said irradiation angle regulating means is arranged in front of said main flashing means and said pre-flashing means.
- 4. A flashing device according to claim 2, in which the irradiation angle regulating means is divided into a part for said main flashing means and a part for said pre-flashing means, each being arranged in front of the respective flashing means.
- 5. An adapter for a flash device having main flashing means for effecting a main flash for an exposure and pre-flashing means for effecting a pre-flash prior to the exposure comprising a light transmission member for matching the irradiation angle characteristic of the light emitted by said main flashing means and the irradiation angle characteristic of the light emitted by said pre-flashing means.
- 6. An adapter according to claim 5, in which the light transmission member is arranged in front of said main flashing means and said pre-flashing means.
- 7. An adapter according to claim 5, which the light transmission member is divided into a part for said main flashing means and a part for said pre-flashing means, each being arranged in front of the respective flashing means.
- 8. An adapter for a flash device having main flashing means for effecting a main flash for an exposure and pre-flashing means for effecting a pre-flash prior to the exposure comprising:
- (a) first irradiation angle regulating means for changing the irradiation angle characteristic of the flash from said main flashing means; and
- (b) second irradiation angle regulating means for matching the irradiation angle characteristic changed by said first irradiation angle regulating means and the irradiation angle characteristic of the flash from said pre-flashing means.
