tnx pointing me to your raw import plugin in your sig, djjoofa.
I am using Mac OSX SnowLeopard and PS cs5 and importing Fuji raf files taken with a Fuji x10 camera.
This camera has the EXR sensor which simultaneously captures two offset 6 mp exposures whose ev differ by one stop. It recombines these exposures to allow increased dynamic range.
Interestingly, photoshop creates 5 different images when i open up one raf file.Find it here:http://dl.dropbox.com/u/29887336/fuji%20x10%20test%20image/DSCF1215.RAF
One large image is full frame, 2848x2144 pixels, wherein you can clearly see the bayer array when viewing the image at 400% magnification. Then there are 4 additional images at 1424x1072, which probably represent the individual GRGB sets of the CFA.
I find many interesting things comparing these images-for example the smooth clear blue sky actually is represented by pixels whose luminance varies. Even when I open up the the processed jpg (http://dl.dropbox.com/u/29887336/fuji%20x10%20test%20image/DSCF1215.JPG
the sky is 'mottled'-but only of course if you 'pixel peep'.
I was hoping to get 'increased resolution' by averaging out the luminance fluctuation of the bayer array filter-lets-eliminating the screen door effect but keeping the 'pristine' photo information. Alas, as pointed out by others above, the actual luminance fluctuation depends on the frequency of the incident light, so there is no simple way to get this. In fact the processed jpg (when desaturated to give a b&w image) is better than the raw image. The concept of looking at IR frequencies to minimize spectral absorption differences of the CFA elements is interesting as just pointed out. But I imagine this would require an IR illminator and a wratten 87a filter. Without the illuminator, the photographs would be rather dark and require long exposures. Of course, with todays new sensors capable of iso 25600 with low noise(take that tri-X!), one might imagine some awesome pics. Anyway, it would make an interesting photograph printed large. Thank you
