Shouldn't deconvolution sharpening help getting rid of the unsharpness caused by the AA Filter?
The PSF should be well known or am I totally wrong here ?
Time will tell ... but what I do know for sure is that I have seen some extensive comparisons using D300's both with and without AA filters. The cameras were put through some rigorous testing and the processing was sophisticated.
The results of the test were very clear, to me:
- without capture or output sharpening, there was a very noticeable difference between the files; these differences were clearly visible in modest sized prints (10"x15" prints)
- with proper capture and output sharpening, it took a bit of work to find the differences in the files and I could not see the differences in the prints
At the time, I was considering having my D700 modified to have the filter removed and concluded it was not worth it. I came to have a better grasp and appreciation of the role of capture sharpening in digital imaging.
