Canon Powershot SX200 on Epic


This Water mill was originally built in the year 1188 and was used to grind corn. The mill had to be rebuilt in 1748 after a fire destroyed the original building. The waterlock and the mill both have been recently restored to old glory. Since June 2009 touristic boats can pass the waterlock in the river Berkel again.
Due to the typical cloudy weather here in the Netherlands, I encountered some exposure problems. The middle region of the terrace and especially everything in front of it, came out much to dark. This could be resolved somewhat by leveling out the lighting on 79 individual photo's before stitching. The face of the man under the umbrella could be fairly easy restored in Photoshop, although every action takes a lot of time on such a large file.
Does anybody happen to know why a 3904 megapixels photo is stored as 20 Gigabyte by the "Large Document Format", while the Raw format was only 10.5 Gigabyte ? Most actions like file opening, saving and cropping now take close to half an hour each !
An impressive Canvas of 90 x 360 cm could be stretched gallery style, which still would give an incredible high resolution : on that print size the resolution of the photo would still be 800 pixels per inch as input, which happens to match exactly our maximum printing resolution. This means that such a Canvas print could be explored with a magnifying glass just like you would be zooming in to the maximum on an online version.
