Regardless of the MacBook Pros display limitations (compared to a high end monitor) I prefer to calibrate MBP than rely on the inaccurate (blue bias) native screen colour straight off the production line. In the field, when images have to be wired, colour is important to me - experience leads me to ignore possible monitor artefacts caused by forcing the monitor away from its native state. At sports events, media centres are often poorly lit. With the addition of a large monitor screen hood (majority of colleagues use them) with its small viewing aperture cutting out the majority of the weak ambient light I feel far more comfortable adjusting images with a Mac Book pro calibrated, than not. Refinement of the RAW files for final Tiff archival library purposes will be completed back in the office on a high end monitor.
