General Discussion about digiCamControl and related photography techniques.
Whath i saying was if you want to trigger cameras it invidiually, but if enough to trigger all in same time then is enough a single microcontroller and two optocouplers and a jack socket per cameras, this optocouplers can be modularized by 5-10 cameras to help easyest connections. So every camera need two connection a usb for image transfer and a shutter release cable for trigger cameras in same time (this isn't possible using usb because usb have a significant lag when triggering cameras). The usb connection limit connection to 127 device per usb hub anyway for 50 camera is a lot of data so between captures need to wait some time for data transfer to be finished. digiCamControl support multiple live view so for every cameras the focus can be set.
Here it is the circuit diagram have at least 2 part, first one with microcontroller connected to pc via usb (or not cam be triggered using a button to) and a another box where are connected the cameras, in diagram are only 3 for simplicity but can be added more in same way or can be made more modules for simplify the connectivity.
Hi Duka, thanks for your work!!Sorry, but i have same problem with the diagram.1. 1503_09 are a 3.5mm jack connector right? I'm working at university project and we must control 2 or 3 Nikon D800 with a 10 pin round shutter relase, must we create an adapter?2. Witch pin of microcontroller must connect to usb port 3. The micro must have a software on-board right? Do you can explain better this diagram?Sorry for all of this questions but we are a department of geology not a engineering and we should use this project for aerial photogrammetry so we must have the shots synchronizeds as better as possible.
