Been on the road.  Too long maybe but getting moire is so random.

 This one caught my interest. The first file is the k-3 and the
 2nd is the K-5 IIs. The K-3 is showing more color moire, but it
 could also be due to the differences in focusing because the
 two shots are clearly not focused on the same spot with field
 curvature rearing its ugly head here. I bet there is some moire
 in your GXR shots if you look close enough. The GR-D shows lots
 of moire in some situations.

Re: K-3 moire

2014-04-21 Thread Boris Liberman
Bulent, I use only Lightroom for all my processing, so I couldn't tell. 
And as I indicated, this happens so rarely that I look at it as more of 
an unusual unexpected surprise as in - look, moire!


I have RawTherapee Portable and I could pass this image through it... 
But beside that - I don't have any tools to work with. If you wish - I 
could send this RAW file your way and you could play with it. Hopefully, 
it would yield something worth sharing on the list.

Re: K-3 moire

2014-04-21 Thread Boris Liberman
Sure, I only wanted to ascertain that I am being understood correctly. 
It often happens to me that I am not.


I should admit that I did not see the moire on the PF examples either. 
I've seen some artifacts, but I wasn't sure as to what to attribute them.


I have some more moire examples from Ricoh GXR-M that are very clear, 
but like I said - 6 images out of several thousands - it is 
*practically* a non-issue. In fact, I am thinking that this new K-3 
variable moire reduction feature is good, but its usability in real 
shooting is extremely marginal. At least this is what follows from my 
experience.

Do you know if this moire (in that particular image) can be remedied

And if yes, do we lose some resolution as a trade off?

 This one caught my interest. The first file is the k-3 and the 2nd is
 the K-5 IIs. The K-3 is showing more color moire, but it could also be
 due to the differences in focusing because the two shots are clearly
 not focused on the same spot with field curvature rearing its ugly
 head here. I bet there is some moire in your GXR shots if you look
 close enough. The GR-D shows lots of moire in some situations.

Re: K-3 moire

2014-04-19 Thread Boris Liberman
Bong, I've AA-filterless Ricoh GXR-M with which I've shot more than 
7,000 images. So far I've had moire on exactly 6 of them, all of which I 
can present for you to inspect.


It is therefore my conclusion that moire is more a non-issue than 
otherwise. Of course K-3 has twice as many pixels as my Ricoh, but even 
if this squared the likelihood of moire, you would have like 36 images 
out of 7,000 :-).

Re: K-3 moire

2014-04-19 Thread Zos Xavius
From the pixel peeping I did, the K-3 seems to pick up more moire
because it is resolving more. On the flip side, it is resolving
significantly more than the K-5 IIs. Also the moire is less pronounced
because it is smaller. What I did see was relatively minor and would
have to printed very large to really make much difference. I also did
some research on the M8 and M9 because I was curious and sure enough
those people using leicas deal with moire from time to time as well.
Also MF shooters tend to have to deal with moire and Capture 1 has had
a moire tool for some time from what I've read. If I did purely
portraits I might go for a regular K-5 II, but as it is, I generally
want to focus on landscapes and scenery, so the IIs wins.

Re: K-3 moire

2014-04-18 Thread Dario Bonazza

H Bong,
Just setup a table with textiles of different kinds and textures, draped so 
that the different parts of each cloth/clothing will distribute at slightly 
different distances from the camera. I bet you'll find moire somewhere. Or 
shoot a cityscape where all kinds of grids will be included (such as nets, 
shades, conditioners grids and such).
That was how I generated moire when testing the K-5IIs soon after its 
launch. However, the moire you'll get will be subtle enough that you'll 
hardly notice and only by inspecting carefully all image areas at 100% 
magnification. RAW images have a good edge on JPEGs for correcting moire.

I mean that moire that is visible in a given camera JPEG can go away by 
itself while converting the RAW file (of its RAW+JPEG pair) into JPEG with 
Photoshop CS6. Perhaps it's some kind of magic (an auto correction function 
of CS6?). Never investigated into this because moire is so rare in my K-5IIs 
pics. Just noticed.
I think I truly don't need the AA filter simulator of the K-3, because my 
subjects have it themselves (move the subject insted of the camera sensor 
and the trick is done). I understand that removing the textiles covering 
your subject also works well... Damn, Iooks like I've selected the wrong AA 
filter simulator!

I'm actually considering a K-5 IIs right now and that's a real

the k-5 II and IIs are undeniable though. I looked through a whole lot
of real world, outdoors pictures and couldn't find much moire. I mean
its there if you really look in spots, but it didn't jump out all over
the place. With fabrics I might have problems. The Leica M9 has a
lower pixel pitch and doesn't seem to produce moire everywhere, but
I'm sure if you look at 100% it probably has some moire. I don't hear
anyone complaining about the M9. I guess my big fear is portraits. The
fabric samples on dpreview look scary. Should I just get another good
old K-5 and call it a day? I'm curious if anyone out there is using a
K-5 IIs for portraits and how that works for them.

Actually, you can A-B it in one particular shoot: subject is wearing

lower pixel pitch and doesn't seem to produce moire everywhere, but
I'm sure if you look at 100% it probably has some moire. I don't hear
anyone complaining about the M9. I guess my big fear is portraits. The
fabric samples on dpreview look scary. Should I just get another good
old K-5 and call it a day? I'm curious if anyone out there is using a
K-5 IIs for portraits and how that works for them.



Moire doesn't really disturb me as much as that thing digital does with 
the sky.

When you are peeping, who cares about the pixels...

 Actually, you can A-B it in one particular shoot: subject is wearing
 fine fishnet in some shots but bare skin in the exact same pose and
 light in others (Alt.portraits of Madame X).
 
 For me the fuss about moire with the K-3 or K-5IIs is overblown by
 pixel-peepers and is not a practical real-world concern.

 I'm actually considering a K-5 IIs right now and that's a real

 the k-5 II and IIs are undeniable though. I looked through a whole lot
 of real world, outdoors pictures and couldn't find much moire. I mean
 its there if you really look in spots, but it didn't jump out all over
 the place. With fabrics I might have problems. The Leica M9 has a
 lower pixel pitch and doesn't seem to produce moire everywhere, but

Quite so; a viewable real world concern. (Which can be dealt with by
shooting raw and sticking with a 16-bit workflow end to end. But
that's--hopefully--another thread ...)

SoI downloaded the k-5 IIs shot of the studio scene from dpreview.
Opened the raw in lightroom and tried the moire tool. Total non issue.
I think I'm getting a K-5 IIs. Thanks everyone.

K-3 moire

2014-04-17 Thread Bong Manayon
The local Pentax dealer lent me a K-3 with the challenge to trip it up to 
produce moire; been behind on the AA/moire issue since I have not rush to 
getting a K-3 for myself soon (and I skipped the 5IIs). Any random thoughts on 
this?
