300D, RemoteCapture and bulb

Hi there,

I wanted to sequence bulb exposures with the 300D and RemoteCapture. I can select bulb as an exposure time, but RemoteCapture refuses to shoot. With 30s and less everything is perfect.

Anyone who made this work?

Hey Tom,

I don't have the 300D, but I do have the Nikon D70 and Capture 4 (the Nikon equivalent of RemoteCapture). Capture 4 won't let me shoot bulb shots via the software - only via the camera or the remote. I'm thinking they just didn't code it into the firmware/software. Perhaps Canon did the same thing as Nikon.

Yes, RemoteCapture won't handle bulb mode.

To control the shutter, you can use software such as DSLRFocus or Images Plus. These work in concert with a custom parallel port shutter release cable (one end plugs into a laptop's parallel port, the other into the 300D's remote shutter release plug).

You can make your own cable: see for details. Or you can pay some one to build it for you... see for Hap Griffin's cables.

Info about DSLR Focus is available at; info about Images Plus is available at

Hope that helped.

Thank you for your quick response.

Seems very strange to me: the Canon IR-Remote Control is just sending IR signals and CAN control the camera in bulb. But the USB-connection cannot. Must definitely be a bug or lousy implementation.

Thanx for the soft- and hardware tips. Unfortunately the serial port is used for LX-200 connection and the parallel for the guide cam sad Maybe I have to look for an additional serial card, maybe USB to serial. Its a laptop...

Still have some hope, cause I got the latest version of RemoteCapture now wink

Take care
