Slow Image capture when using External Hard drive

I am trying the trial version of iStopMotion. I really love the interface but whenever I hit the capture button it takes a full minute to capture the image and save it to the project file on my external hard disk drive. I have a feeling this drive might be defective, but it also does the same thing on my other hard disk drive. Is this slow image write speed normal?

Hi @jurassicbajanscott Thanks for trying out iStopMotion. The capture speed should be much quicker than you report. I suspect that your camera takes a long time to transfer the image to the Mac. This can be changed by changing the picture format in the camera. What camera are you using and how is it connected to the Mac?
