Tried the same idea again but with 100 individual photos, meaning that this covers a time frame of 3 hours and 20 minutes!
Similarly to the first attempt in Portugal this one is plagued by cloud, which to me is no where near as effective as having the blue sky running through. Also the blue in these photos changes quite dramatically between frames, I think this is due to the sun shining on and off the camera and changing the settings quite drastically. With the 8 x 8 one the clouds never took over the full frame and I feel that in this grid they don't at the start, do in the middle and don't again at the end which looses the connection from start to finish, making it a lot less effective than the others. At least the 5 x 5 one stayed mostly cloud for it all, in doing so it kept the flow between the different frames, this one doesn't and so looses the relationship the individual photos share with the photo taken after it and the photo taken previous to it. There is nothing to say that these photos are all linked.
