1. A method comprising: providing a low resolution multispectral digital image from a camera imaging system, providing a high resolution monochromatic digital image from the camera imaging system, where the images are of the same scene and have a degree of overlap, generating, at the camera imaging system, a single digital file comprising the images, where the images have a common file format, and are suitable for processing into a fused high resolution multispectral image by a client device, and where the combined data volume of the low resolution multispectral digital image and the monochromatic digital image is less than the data volume of the fused high resolution multispectral image.
