He didn’t think his 2D graphs of chemical concentration along a particle’s radius would be suitable for an audience he’d be presenting to, and that they’d be better served seeing an animation of how the concentration varied over time and [...]

Capturing an Image from a WIA-compatible Digital Camera

We’ve had a research project requiring a fair amount of image acquisition and processing, requiring  higher resolutions than most industrial cameras can offer. As a result, we’ve tried at least three different digital cameras (Canon PowerShot S3is, Nikon D40, and Canon PowerShot SD780is). Each of them has their own advantages and disadvantages:

S3is advantages:  good control [...]
