Methods and systems to relay short duration coded pulses of light emitted by a first flash device to a second flash device, which may be remote, using radio signals, wherein radio signals comprise data representative of short duration coded pulses of light from the first flash device which may comprise one or more binary commands and/or activation signals emitted by the first flash device. A first radio communication device may sense coded pulses of light from a first flash device and in response transmit radio signals representative of the coded pulses of light, and may subsequently stop transmitting radio signals following the transmission of radio signals representative of the coded pulses of light. A second radio communication device may receive the transmitted radio signals from the first radio communication device and may cause a light element comprised of the second radio communication device to emit coded pulses of light to a second flash device wherein the coded pulses of light to the second flash device may be substantially representative of the coded pulses of light emitted by the first flash device.

1. A method of wirelessly relaying coded pulses of light from at least one first flash device by the intermittent transmission of radio signals, the method comprising: allowing a sensing element of a first radio communication device to become perceptible of a phenomenon associated with the emission of at least one pulse of light by an at least one first flash device;allowing an at least one first microprocessor of a first radio communication device to become perceptible of a sensing element;allowing a radio transmitter having an antenna element to communicate signals with an at least first microprocessor;an at least first microprocessor causing a radio transmitter to begin transmitting radio signals upon receiving at least one signal from a sensing element;an at least first microprocessor causing a radio transmitter to stop transmitting radio signals following a process of receiving at least one signal from a sensing element. 2. The method of claim 1, wherein the process of receiving the at least one signal from a sensing element comprises receiving at least a first pulse of light of a pulsed data byte. 3. The method of claim 2 wherein the process of receiving at least one signal from a sensing element comprises receiving a plurality of pulsed data bytes. 4. The method of claim 3 wherein upon the completion of a first characteristic interval of time a preparation for trigger pulse is performed. 5. The method of claim 1 wherein a packet overhead is transmitted from a radio transmitter in response to receiving the at least one signal from a sensing element. 6. The method of claim 5 wherein a pulsed data byte is at least partially buffered by an at least first microprocessor during the transmission of a packet overhead. 7. The method of claim 5 wherein the interval of time required to transmit a packet overhead is subtracted from the interval of time between the transmission of radio signals representative of two or more pulsed data bytes. 8. The method of claim 5 wherein a packet segment representative of a pulsed data byte is transmitted from a radio transmitter following the transmission of a packet overhead. 9. The method of claim 8 wherein a packet segment comprises a data representative of at least a pulse or a non-pulse of light. 10. The method of claim 9 wherein a packet segment comprises a filler data between at least two portions of data representative of at least a pulse or a non-pulse of light. 11. A method of wirelessly relaying a sequence of binary commands and a terminal trigger command communicated by a flash device, wherein binary commands are separated by a time interval no greater than a predetermined duration, and wherein the trigger command is characterized by following a binary command by a time interval greater than the predetermined duration, the method comprising: detecting, by a first radio communication device, a sequence of binary commands emitted by the flash device;formatting a wireless transmission to include a corresponding sequence of data segments each having the same duration of the binary command represented thereby, and separated by filler data segments, at least one of which has a shorter duration than the corresponding time interval separating subsequent binary commands; andtransmitting, by the first radio communication device, the wireless transmission after a time delay in which the wireless transmission is at least partially formatted. 12. The method of claim 11, wherein the time delay is offset by at least some of the filler data segments being of shorter duration than the respective time intervals separating the binary commands. 13. The method of claim 11, further comprising: detecting, by the first radio communication device, after initiating the wireless transmission, a terminal trigger command following the sequence of binary commands; andformatting, while transmitting, the wireless transmission to include a data segment representing the trigger command, separated from the data segment corresponding to a final binary command in the sequence by a filler data segment having a longer duration than the predetermined duration but having a shorter duration than the time interval separating the trigger command from the final binary command. 14. The method of claim 13, further comprising terminating the wireless transmission after the data segment representing the trigger command is transmitted. 15. The method of claim 11, wherein the wireless transmission is formatted as a radio packet, and wherein the data segments are radio packet segments. 16. The method of claim 15, wherein the delay is caused by buffering at least a portion of the detected sequence of binary commands. 17. The method of claim 11, wherein formatting a wireless transmission at least partially overlaps the first radio communication device detecting the sequence of binary commands. 18. The method of claim 17, wherein transmitting the wireless transmission at least partially overlaps formatting the wireless transmission. 19. The method of claim 18, wherein the transmission of at least one data segment of the wireless transmission is begun prior to the detection of the entire binary command to which it corresponds. 20. A method of wirelessly relaying sequences of optical commands emitted by two or more flash devices, wherein each sequence of optical commands includes a series of one or more binary commands followed by a terminal trigger command, and wherein the emissions are initiated at different times, the method comprising: detecting, by a first radio communication device, a sequence of optical commands emitted by a first flash device;detecting, by a second radio communication device, a sequence of optical commands emitted by a second flash device that are initiated after the initiation of the sequence emitted by the first flash device;formatting first and second wireless transmissions to each include, respectively, a corresponding sequence of data segments, wherein each data segment has the same duration of the optical command represented thereby;transmitting, by the first and second wireless communication devices, respectively, the first and second wireless transmissions such that the data segments representing the trigger commands are each transmitted substantially in real time with the emission of the trigger commands by the first and second flash devices; andterminating each wireless transmission upon transmitting the data segment corresponding to the terminal trigger command;wherein the second wireless transmission is transmitted following the termination of the first wireless transmission.
