How do I increase the dynamic range of my camera?
For the sake of this article, dynamic range is defined as the difference between the maximum and minimum amounts of light that a sensor can measure. This is bounded on the upper end by the sensor’s full well depth (the maximum charge, measured in electrons, that any pixel can contain) and at the lower end by the camera’s read noise. It is measured in a number of different ways, but one simple method is to examine the number of different levels of grey that can be distinguished. The greater the dynamic range of a camera, the more grey levels that will be distinguishable in the resulting image.

How is the electronic shutter on a CCD implemented?
Like conventional film cameras, digital cameras require a shutter (either an external mechanical or electronic shutter) to control exposure for image quality. This article describes how the electronic shutter on a CCD is implemented.

How to apply correction factor values to perform falloff correction
This article explains how to perform falloff correction on an image by using the correction factor values obtained from the ladybugGetFalloffCalibration() function in the ladybug libary. This article is applicable to Ladybug5+, Ladybug5, Ladybug3, and Ladybug2. The Ladybug library has functionality to perform falloff correction on images, however in some situations a user may want to implement falloff correction themselves. One possible reason is performance increase which could be gained from performing falloff correction in CUDA.

How to determine and interpret the Bayer Tile pixel format of a camera
All of our color imaging products are capable of streaming the raw, stippled 8-bit or 16-bit-per-pixel Bayer Tile image data to the PC, which can then be color processed / interpolated to 24- or 32-bit BGR data. See "Different color processing algorithms" for further details on color processing. To configure a camera to output raw Bayer data, consult your camera's Technical Reference manual.

Image capture freezes with a FireWire camera after a period of successful image capture
During the capture of images from a FireWire camera, it has been reported that the image display may freeze and the grab function, e.g., flycaptureGrabImage2(), may start failing (e.g. FLYCAPTURE_FAILED).
