Test on Kodak EIR film



Frank,

>I'm not sure you need to stop down to f. 16 unless you need the depth 
>of field.

Actually, I want to see whether there are some differences between 
2 shots of same scene with one taken with a larger aperture/shorter
time combination while the other taken with an equivalent smaller 
aperture/longer time combination.

>buildings show up as a shade of blue and have no significance 
>except if there is some paint or coloring on them.

Most of the buildings are white. No painting or coloring.

>were you using any filter with it? usually a yellow filter is fine.

Of course, I used a yellow filter when taking the pictures.


I have to state once more that all pictures taken with
larger aperture/shorter time exposure combinations show an overall
RED tone while those taken with smaller aperture/longer time exposure 
combinations show an overall BLUE tone.

Can anybody help me to explain the phenomenon ?


regards,
Symon
