Anti Moiré funtion

Unregistered User · 01-08-2014, 01:45 PM

Hi there. I have tested the anti moiré in my own way since I still have not seen any moiré in any of my pictures. I wanted to know how much softening the two different settings would create. Not much if my findings are correct. Is it functioning correctly on my K-3 or should there be a bigger difference?

The pics are taken with fixed WB, same shutter speed and f-stop on tripod with 2s delay. Cropped in ACR with sharpness on 100%, Radius 1, Detail 25, Masking 0 and Luminance 0

ISO 100, 1/60 and f/4.5

Pic 1,4 No AA
Pic 2,5 Level 1
Pic 3,6 Level 2

Not sure if I'm missing anything, but I don't see moire even in the AA-off shots.

I can´t seem to be able to produce moiré but my thinking is that the pictures with the Anti AA turned on should be less sharp than the ones with it turned off. I find them not so much lesser sharp, therefore I ask you if my K-3 is performing as expected or not.

If you're applying sharpening in post (especially that much sharpening), it's probably going to eliminate any visible difference when there are no fine details.

Check out this page for some examples of what to look for in real photos:

Honestly, if you shoot any fence or building at a distance (with a sharp lens) chances are that you'll see moire somewhere. You might need to get "lucky", but a few different subjects will probably suffice.

The details in those test charts are not small and sharp enough to produce moire.

Also keep in mind that unless you are using a very sharp lens and have it perfectly focused you will not get any moire either, so you won;t see any difference whether the AA function is on or off.

Ok, so I guess I will keep trying. =)

The thing is that I am not trying to create moiré in the pictures. I am trying to se a sharpness difference when using the different levels of anti moiré. These pics is not as on my screen but not to far away. There is detail in the paper that gets a little softer but not at all as much as I expected. If find pics compared between the K-5 II and K-5 IIs to be much more of a difference. That is why I wrote this thread.
