Yes that's moire

I was stopping on the way back from doing some bird photos- certainly can't see any hint of moire in those. The top 4 in my photostream are recent K5-IIs photos, the rest are trusty old K7:

I meant to add a comment on PF. I'll need to do some tests, but one added benefit *appears* to be that PF is much better controlled on the K5-IIs than on my K7 in high contrast lighting situations. Can't comment re K5 or K5-II.

Thanks asgr.................so how would you PP to get rid of it?

asgr · 12-02-2012, 08:27 AM

Just to demonstrate it is Moire, here's the same seen but at F4 (previous was f5.6).

Both were shot with 35mm Ltd. You can see the coloured bands going at a different angle now. This lens is probably too sharp for it's own good :-D It's noticeable how blurry (but moire free) similar shots with my K7 are.

As for removal in PP, I haven't tried yet. If somebody wants to have a stab, the raw is at https://dl.dropbox.com/u/10495241/_IGP6273.DNG

Looking around, LR4 looks like it might be able to do the job. I only have LR3, and that doesn't have any moire removal tool per se.

Cheers,

Aaron

I say don't bother with the moire correction , just use the F4 version, moire in that sample is so smooth and straight distributed, almost anybody can buy it as a wall paint, or just select the area and decease the color saturation in PS, that'll do.

What an excellent thread idea! If the community can show some restraint (more photos, less verbiage) it might become a valuable resource for people considering purchase of the K5 IIx.

adobe camera raw has a brush too, works almost the same as LR's
it makes the left building a little whiter, but no moire after the brush.

Here's some 645D and D800E moire:

Great to see LR4 does the job easily.

I was surprised about it's presence on the left building. It must have something to do with the window pattern being offset.

I'm not to concerned with moire, it happens from time to time no matter then camera. This is a example from the plain ol K7. Some material is just very moire inducing and others are not.

The lens used was the DA* 50-135mm

obscura · 12-02-2012, 05:55 PM

This is true, some materials are moire hell, especially fabrics like the one you posted, but color moire is easy to fix.
from the photo i understand that you shoot weddings, how often do you see moire like this? would you get the k-5iis or you think its going to be a problem ?

there is some residual moire (pattern not color) near the pocket, maybe with a stronger brush...

I already bought one, as you said its fairly easy most times to edit, also it showed up in that wedding maybe 10-15 times out of hundreds. You really have to be the right distance, with the right camera settings most of the time and as many have pointed out adjusting the Fstop can drastically reduce those chances as well. Generally speaking I almost never see Moire, just this wedding in particular did the groom have something that really induced it.
