not sure if you have figured it out or given up, but I recently used a HC-05 module as master to receive data from a GlobalSat bt-338, I think this is a similar process to what you want to do. I also had some headache. I'm not sure if it will help but here is some advice.
First, make sure that that the settings are right on the HC-05. Put it in AT command mode. Do this by drawing the EN pin high and holding the button on the board before powering the board(or drawing pin 34 HIGH if there is no button). Once in AT command mode the red LED will blink slower. Make sure to set the HC-05(master) password and baud rate the same of the cameras BT(slave). find the address of the slave device.
Then do the following at commands:
AT+RMAAD //clears paired devices
AT+ROLE=1 //sets it as master
AT+RESET //resets the module
AT+PSWD="password"//sets the name of your password(must be same as slaves password)
AT+UART=baud rate//set equal to slave's baud rate
AT+CMODE=0//sets to connect to a fixed address
AT+INQM=0,5,9//inquiry mode standard, number of devices, timeout
AT+INIT//initiates spp profile
AT+INQ//returns available device's address, class, and signal strength
AT+PAIR=xxxx,xx,xxxxxx,9//devices(slave) address is separated by commas like such and 9 seconds is the timeout
AT+BIND=xxxx,xx,xxxxxx// device's(slave) address
AT+CMODE=1//sets it to connect with paired devices
AT+LINK=xxxx,xx,xxxxxx//device's(slaves) address, links the devices
once connected the led should blink quickly every 2ish seconds
once linked, you can use the arduino to send data to the HC-05 using pins 9 and 10 with SoftwareSerial.
I hope this is helpful and feel free to ask anymore questions.
