1. A system to wirelessly actuate a remote camera flash device comprising: a first radio communication device coupled to a camera; andat least a second radio communication device coupled to the remote camera flash device, wherein, the first radio communication device transmits at least one radio signal to the second radio communication device in response to receiving camera communications sent from the camera;wherein the second radio communication device sends pseudo camera communications to the remote camera flash device in response to receiving the at least one radio signal; andwherein the second radio communication device does not transmit a radio signal. 2. The system of claim 1, wherein the first radio communication device comprises pseudo flash communications to send back to the camera, which are substantially similar to flash communications that the remote camera flash device comprises and sends back to the at least second radio communication device. 3. The system of claim 2, wherein the pseudo camera communications sent to the remote camera flash device are substantially similar to the camera communications that the camera sends to the first radio communication device. 4. The system of claim 3, wherein the camera communications comprise of a plurality of unique data streams, wherein each of the plurality of unique data streams comprises a data packet, wherein each data packet comprises a plurality of electronic bytes. 5. The system of claim 4, wherein the plurality of electronic bytes are separated by time gaps. 6. The system of claim 5, wherein the first radio communication device identifies what type of the at least one radio signal to transmit to the at least second radio communication device by an identifiable byte from the plurality of electronic bytes in the data packet. 7. The system of claim 6, wherein the identified radio signal is transmitted to the at least second radio communication device during at least one of the time gaps. 8. The system of claim 6, wherein the first radio communication device sends a unique pseudo flash communication from the pseudo flash communications back to the camera, wherein the unique pseudo flash communication corresponds to a unique camera communication from the camera communications. 9. The system of claim 8, wherein the remote camera flash device sends a unique flash communication from the flash communications back to the at least second radio communication device, wherein the unique flash communication corresponds to the unique camera communication. 10. The system of claim 1, wherein the first radio communication device comprises a radio transmitter and the at least second radio communication device comprises a radio receiver. 11. A method to wirelessly actuate a remote flash device comprising: coupling a first radio communication device to a camera that is configured to produce a plurality of unique camera communications, each consisting of a unique sequence of data bytes;coupling a second radio communication device to the remote flash device;receiving, by the first radio communication device, data bytes produced by the camera as part of a unique camera communication;identifying the unique camera communication based on the received data bytes before the first radio communication device has received the entire camera communication;mimicking an electronic flash response from the first radio communication device to the camera based upon the identification of the camera communication;transmitting a radio signal from the first radio communication device to the second radio communication device based upon the identified camera communication; andmimicking the identified camera communication to the remote flash device by the second radio communication device. 12. The method of claim 11, further comprising transmitting the radio signal before the first radio communication device has received the entire camera communication. 13. The method of claim 12, further comprising transmitting the radio signal during a time gap between a plurality of data bytes of the camera communication. 14. The method of claim 12, further comprising identifying a particular data byte among the plurality of data bytes as the basis for transmitting the radio signal. 15. The method of claim 14, wherein when identifying the particular data byte comprises identifying the data byte that corresponds to a flash command, the first radio communication device transmits the data byte that corresponds to the flash command to the second radio communication device; and wherein when a data byte that corresponds to a flash command is not identified, the first radio communication device transmits a signal representative of the identified camera communication. 16. A method to simulate two-way serial communication between a camera and a flash device coupled to the camera comprising: coupling a radio transmitter having a first microprocessor to the camera;coupling a radio receiver having a second microprocessor to the flash device;receiving a first serial communication by the radio transmitter sent from the camera;transmitting an index signal from the radio transmitter to the radio receiver based upon the first serial communication, wherein the index signal consists of a data sequence representative of the first serial communication, and wherein'the data sequence of the index signal is shorter than that of the first serial communication; andsending a second serial communication to the flash device from the radio receiver that is substantially similar to the first serial communication. 17. The method of claim 16, wherein the first microprocessor: identifies the first serial communication by a byte from among a plurality of bytes that comprises the first serial communication;provides a response back to the camera based upon the identified first serial communication; andprovides the index signal based upon the identified first serial communication. 18. The method of claim 17, wherein the second microprocessor sends the second serial communication based upon the received index signal and receives a third serial communication back from the flash device based upon the sent second serial communication. 19. The method of claim 17, wherein when the first microprocessor identifies the byte from the first serial communication that corresponds to a flash command, the transmitted index signal consists of the byte that corresponds to the flash command. 20. The method of claim 18, wherein the response provided back to the camera is substantially similar to the third serial communication.
