Thank you, Frans, for bringing some sense into this benighted thread. :-D

I'm sure you've both seen this paper by Guttosch, but just in case: http://kronometric.org/phot/sensor/fov/Color_Alias_White_Paper_FinalHiRes.pdf

Not sure about that, Osman, couldn't see any smearing on the red roofs. Here's the "YAVAS" at 800%: Can't even blame JPEG blocking because you saved with no subsampling and quite low compression. I ...

At one time, Foveon data was quite widely available, for example when AVC Emporium was selling F13/DP13 sensors . . . http://www.avcemporium.com/color-sensors/ . . . and sensor data sheets were in ...

For me, Scott, the latter. That matches, for example, FastStone Viewer's re-sizing options. That is to say, if you select 200%, the pixel width box automatically doubles. If you enter double the ...

Just to un-clarify this exhange, Richard F Lyon (a well-respected dude) seems to know of a good few definitions for "pixel" . . http://kronometric.org/phot/sensor/fov/ABriefHistoryofPixel2.pdf Pers ...

A blunt one-line command gets you nowhere with me, sorry. I'm done with this thread.

Oops, Scott, says the circling shark. :-D

We call it "horses for courses" . . Reference? Reference? Vague and rhetorical question. I do not. https://www.dpreview.com/forums/post/59754873 With no references to back up the one-line ...

I have the 2X but haven't used it seriously yet. What kind of experience (lens, camera, scene) are you referring to? George, I live on 10 acres of woodland. Take a look at my gear list and see if ...

Correct - even a hard-jaggied edge has "only" 0.64 MTF at Nyquist (sensor MTF, ignoring lenses and post-processing). http://www.falklumo.com/lumolabs/articles/sharpness/index.html Or indeed as ...

I never re-sample images before post-processing and would not recommend it to anybody whose Editor is capable of zooming the review image, sorry. An edge "plagued with jaggies" in my book is ...

Pretty rude, that. Complaint filed - 'cracks'. Back to the 'ignore list' Truman goes.

Gotta luv this forum. We're never going to see "scaling" defined in this thread. Beside which, if we can ever avoid comparison by MP count, F7: 9.12um pitch. F13: 7.8um pitch F19/F20: 5um pitch. Th ...

I don't understand your comment about the resolution - it came out 2640x1760px and JPEGsnoop tells me it is Y'CbCr is 4:2:2 (2x1) and the compression ratio is 5.94 and 4 bpp - all pretty good for ...

Thanks for the link, George, excellent results!

My case does indeed show the magenta. Thanks for the down-loads. There could be a problem with the X3F - in SPP 4.2 the WB said "Sunlight" and would not reset to anything else, no idea why . . . I ...

A great improvement which shows off the less-clinical** look of the DP2s. :-D I prefer the bonus shot to the first. ** the forum 'word of the week'

Reiner, Could you post the X3F and the RT .pp3, please? For your interest, I have an SD14 blown shot (daylight) that RT5.0 does nothing with highlight recovery because RT's conversion gives a lower ...
