I just thought I would attach a couple of scans here. The scans are unaltered, and you can clearly see the 'yellowness' of the images. Notice how it even tends to turn the sky green in the picture of the tree. What's also kind of interesting is that the yellowishness is supposedly intended to counteract the blueness of high altitude shots. Yet both of these pics were taken at significant altitude (about 8000ft in the first, over 10000ft in the second).
