Moire pattern

Hi all:
My slot loading iMac G3 400 has developed moire pattern on right side of screen. This developed after all of the below had taken place.
Original Problem: Screen very dark; some spontaneous shut downs.
Connected a Viewsonic 17' to VGA port. Calibrated Viewsonic darker [it's a much brighter monitor]. This made iMac display extremely dark [not a biggie since I was using the external VGA]. Worked fine for a couple of days until the power was turned off in my building for 8 hours [iMac not on when power was turned off]. When power came back on, iMac would not boot -- start button would flicker, then switch off. I thought: Hmm ... maybe the battery is dead ....
Installed new battery. Wouldn't boot, but sometimes got startup sound and gray/blue, pre-boot screen, but no happy mac. Attempted to boot several ways[disconnected VGA; printer; DSL modem; Belkin powered USB hub; reset button; zapped PRAM; Command + Control down, but no luck & no longer got startup sound. Shut it down for a couple of hours, then booted successfully, but iMac screen still seemed a bit dark. Recalibrated and improved. Reconnected Belkin hub, DSL modem, but not the VGA monitor or printer[but would like to].
Would appreciate any help, specifically re. moire pattern, but general info on above also welcome.
thanks.

Reshoot with a different tie?
Depending on how much movement there is in the frame and etc there are several things you might do.
If it's the typical medium/close-up corp shot, you might just try duplicating the video to the second layer garbage-matting in to the tie and blurring it.
Or export representative frames to photoshop and from those frames build a tie overlay that you've blurred in photoshop.
Any way you do it, it'll be messy.

Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2008 iMac which is running 10.6.8. What does this mean?

Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2007 iMac which is running 10.6.8. What does this mean? I've attached some screen shots below.
Also experiencing some funky issues with my wireless keyboard. With new batteries, it will just stop functioning. Certain keys intermittently won't work. Also the fans go on as soon as I turn the computer on - some times they stay on and sometimes they don't. Ever since upgrading the operating system - I've been having many issues with this iMac. Not happy. Any answers out there?

Thanks for your reply LexSchellings, There is no disc in the drive and I went through the suggestions you put forward on the phone with Apple support without any luck. I can put a disc in but it pops straight back out again without registering on finder.
The idea of using an external drive was to enable me to avoid the cost and loss of productivity whilst machine in repair... if I have to take it in to get the old drive removed than I might as well have a new internal drive put in, although I do worry about the reliability of these apple drives given my experience with this one coupled with my limited online research ... on line forums seem to be full of people with the same problem (although perhaps searching such forums is bound to make it seem a common problem as users with perfectly working machines are less likely to post (?)) Your reply suggests that no external drive will work whilst the existing drive is in place.
As a postscript: I do realise that this is a user forum ...my secondary question was asking if anyone knows how to put forward a case/complaint to Apple... I can't find a link on the support page that would enable me to do so and I was wondering if anyone on this user forum had any ideas/experience..

Moire pattern on screen

Ther is a moire pattern on my screen. Why?

Hello
simple way to try diagnose a visual problem is to take a snapshoot of part of screen you think is defective
- if your visual problem not appear on snapshoot file could be a screen problem
- if your visual problem can be see on snapshoot file could be a vram / mother board / graphic card problem
to take a snapshoot use cmd-shift-3 or cmd-shift-4 , that create file on desktop
second way is to plug an external display see if problem is same or not

New MBP 17-inch anti-glare display creates a moire pattern when scrolling

This is kind of hard to explain: The color on the display is fine when a page is stationary, but when I scroll vertically, the blues (especially light blues) and reds get a strange tint to them and create an effect that's hard on the eyes. The graphics don't break up or anything but the color vibrates. It's very uncomfortable to watch. I've owned and used many Powerbooks and Macbooks over the years and this is the first one that's had this problem. It's like a moire pattern, or something. Very odd.
Is anyone else noticing this on the anti-glare display? I'd like to know before I go ahead and return this MBP.
Thanks

Sure. No two sets of circumstances are exactly the same, so no one else will have experienced exactly what you've experienced, including the prior replacement of an earlier MBP model for repeated display problems that you haven't specified. AppleCare will weigh all the circumstances of your current issue on their own merits and make a decision about what to do without reference to other people's problems. No one here knows what that decision will be, whether you believe me or not. Call AppleCare.

New white macbook, moire pattern in upper left

we bought this from the store on Friday so it's brand new. in the upper left of the screen, there is a subtle moire pattern that fades as you go right and down on the screen. it's faint, but it drives me crazy when i use it - but my wife (it's her computer) doesn't notice/mind it.
is this a bad display or a bad driver? i've never seen anything like this or heard of it happening. i can't imagine that it's being dithered like this. it's running 10.5.7 w/ all of the available updates installed.

Without seeing it, it's hard to say. But, as you've just purchased it, I would suggest that you immediately bring it back to have it looked at. Where ever you purchased it from, they should have floor models that you can look at to make a comparison. It's best to bring it back right away as that makes it obvious that the problem was there out of the box and you'll be more likely to get a replacement vs. a repair if there is a problem.

What settings to avoid "moire" patterns on TV

I use QT 7 pro and liveslideshow to generate a QT movie with music which I then burn to DVD as video using Toast Titanium.Os =10.3.9
When I watch the DVD on my TV (PAL) some images show a moire or interference type pattern. I think it is fine detail sets it off. The images I use are from Photoshop.
I know TV 's have different shaped pixels to CRT computer monitors. Is this what I need to change?
Is there a setting in Quicktime I should use to re export the movie for viewing on a TV?
Many Thanks.

HDV exported from FCP 7 into iDVD has red/green moire pattern?

Yesterday I was testing some native HDV (1440 x 1080) in FCP 7.
I exported it as a QT Movie as I used to in the good old days but when I imported it into iDVD the image was coverd with a greeny-red moire type pattern.
It wasn't a serious problem as I simply re-exported as ProRes and that cured it.
However, I am curious as to what may have caused it as it never occurred in the dim and distant past.

Thanks for testing and confirming my findings Russ.
I didn't get this problem back in 2008 as native HDV, FCP and iDVD worked OK together . . . at least in that respect.
However, in those days I was using FCP 6 and I wasn't using OS X 10.6.8 or later. So maybe there has been a change in FCP 7 or the OS that has caused the problem.
OK, long answer to Michael as to why I was doing this "test".
Back in 2008 I bought a new iMac and a Canon HV20 HDV camera expecting to see a dramatic improvement in image quality . . . . which I did . . . . on the computer .
I hadn't mastered DVDSP and Compressor and preferred to use my familiar iDVD which did everything I needed.
So I plonked my edited footage in iDVD and burned a standard def DVD.
I was horrified to find that the DVD footage shimmered badly where any straight lines or fine detail appeared but even worse was the appalling judder that occurred with any subject or camera movement.
I spent several weeks investigating and testing, deinterlacing, swopping fields, converting to AIC and ProRes etc. etc. to no avail. (Incidentally if I set my camera to downconvert to DV during capture, the DVDs produced were fine, but I wanted to edit those beautifully detailed HDV images not DV ones).
Finally a suggestion from Tom Wolsky solved the problem . . . . . put the finished edited project in a DV-PAL sequence in FCP and render it.
The result was rock solid images and beatiful smooth motion.
However, the downside was the time it took to render the HDV project to DV which I found unacceptable.
So I gritted my teeth and taught myself to use DVDSP which got rid of the problem of instability but introduced other, admittedly lesser, but well documented problems. But that's another story.
Now we come to the present.
Last year I bought a Panasonic SD800 3 MOS AVCHD camera, edited in FCP X and exported either to AVCHD Discs or standard DVD.
A few weeks ago I was showing a friend how to use iDVD and the only footage available was my AVCHD stuff.
I used it, expecting the same (or even worse) instability as I had found with HDV.
To my pleasant surprise, the resulting DVD was acceptably stable with smooth motion.
So a couple of days ago I started wondering whether HDV in FCP X and iDVD would be OK.
It was, which meant I could go back to iDVD occasionally when I wanted one of its custom canned menus.
Then I wondered what HDV in FCP 7 sent to iDVD would produce.
Hence my recent test!
I bet you wished you had never asked, Michael.

Text descenders along with moire patterns

Photoshop CS2
Microsoft came by with a Vista auto update 10/28 and screwed things up (again). Now the bottoms of all the text on Photoshop CS2@ "file info" is gone. Also, my screen has moire "ripples" (non-moving) on many of the photo displays. The text problem is popping up only in Photoshop but the moire is in most the photo displays no matter what software. I could use system restore to get back to normal but I really would like to have the Vista updates (the ones that work).
Garry DeLong

Ah me. This may be one of those things that turn out not to be worth the effort. I've disabled all except the System>Library>Fonts fonts :
Courier.dfont
Geneva.dfont
Keyboard.dfont
LastResort.dfont
LucidaGrande.dfont
Monaco.dfont
Now the problem is even worse. The pages I use to test "Flash font screwiness" are
1. http://www3.iath.virginia.edu/waters/timeline/index.html (just because it shows two problems:
1a. The main text of the timeline and Category areas
1b. The cutoff heading in the item box that appears when a map item is clicked)
2. http://maps.google.com/ Streetview of anyplace
2a. There is supposed to be text showing in Streetview, and I see only little blank boxes.
I've just been to both pages on my dear wife's old Macbook and they work fine. Beautifully, even. And both Firefox and Safari show the broken text on my G5. So you're right, I have some kind of buggy font business going on. Blah. I suppose I need to reload my System fonts, to begin with. I don't even remember where to get clean copies. Maybe my original old Install discs?
I'd really hate to have to attempt to rebuild this System! The Install on the discs is 10.3.5, and I can't say whatall has been added in the way of plugins and such.
Thank you, DB, for giving me direction. I wonder, though, if this is a font problem per se? NONE of the fonts I'm trying render these Flash pages correctly *on my machine.* But, and this could be a big caveat, I don't see problems with fonts in other applications. All my Adobe Creative Suite applications seem fine. PDFs display fine. The Finder is fine. Text renders perfectly well on web pages such as this one. It's only on Flash enabled web pages I have this problem.
I guess it's possible some System font is playing havoc with Flash, but I don't really see how, when they don't seem to create any other problems. Or at least, any problems I've noticed. Odd.
Has anyone seen my Flash problem before?

Glitchy, moire pattern artifacts after exporting h.264

I just exported an h.264 1080p video and got these strange glitching artifacts at random places in video. They hapen for about 1-2 minutes and then go away.
I checked the timeline and could find no pattern to the glitches.
Attached are a few snaps of what Im looking at.
Im exporting at the correct framerate.
Im using vimeo's preset for 1080p video.
I upped the bitrate from 5mbps to 6mbps. (vimeo had it at 5)
Any ideas on what went wrong? Should I make the bit rate higher? Do the target and maximum bitrate need to be the same? Or should max be slightly higher?
First time Ive had this happen...

The only way I know of for artifacts like that to be introduced is during shooting. It's a factor of the details in the scene the the resolving power of the camera.

How to remove a repeating 75 to the inch 'quarter-moon' pattern?

I am working with old images, including those from newspapers, and have become quite adept at repairing them with PS. I am familiar with most of the techniques for removing scratches, dust and half-tones, but I have difficulty in dealing with one particular feature of some of the photos unless I manually click about 50,000 times per photo. The feature is: photos that have been printed on a roughened surface that has a repeating 'quarter moon', 75 to the inch. A small sample can be found at:
http://jucreek.googlepages.com/temporary
When I am repairing a photo, I work first on a coarse scale on everything but the face; then I zoom in and on a much finer scale touch up the face, reasoning that people are much more aware of facial blemishes than elsewhere. In the past, with photos similar to the one in question, I take this approach one stage further: I try to remove most of the quarter-moon pattern (other than on the face) with the blur tool using a large diameter, staying away from edges so they are not disturbed; then I zoom in on the face, working on a much finer scale, and again staying away from edges and from the eyes. i.e. I leave the pattern on and around the eyes, reasoning that the eyes are the most important part of the face and unless the pattern is distracting when viewed normally, the eyes should be left alone.
Can anyone suggest a better technique for removing the effects of this quarter-moon pattern? It is of concern to me because at 75 to the inch I am pretty certain that the pattern is going to cause problems when I print the image. The original photo looks OK, but I suspect moire patterns will come to the fore if the pattern is not removed before I print.
Does anyone know what this pattern actually is? Out of approximately 2000 pre-1960 photos I have scanned, maybe only 6 or 8 have this type of pattern, and I think all of them they may have been studio photos.

I'm looking forward to the day (although I suppose I'll be long dead before it happens), when PS has enough intelligence to be able to remove spots and half-moon patterns by itself. When you can sit in front of your computer and say to PS:
i See all those spots, can you remove most of them the way we talked about yesterday. You know, make sure that after you remove a spot that us humans won't be able to detect the change. If you're not sure, how about flagging any spots you're not sure how to handle, and I'll go over them with you later on so you can learn how to do those yourself next time. I'm going for a cup of coffee. Shouldn't take you long, should it?
i About 3 to 4 minutes for that one. What'll I do after that if you're not back?"
i Put it on that page next to the woolscour, and make up a caption. You'll find the details in the photo file. And don't forget to add a gradient fade so the sky fades to nothing, and flow the text into the fade like you did for the swimming pool photo. I'll be back in about 10 minutes."
I can dream, can't I?

Swatch / pattern alignment

I have a pattern I use frequently that is a B&W diagonal stripe. This is used in fairly small areas and for print (as shading for bar graphs and such).
Recently my client noted that where the pattern tiles, the ends of the lines do not align perfectly and so there's almost a moire pattern where the ends meet.
I wish to make this a seamless pattern but not sure how to do it. I know the basics of pattern making but have searched online in vain for the answer to this one. All responses appreciated.
Leslie

Create a generous area of your diagonal lines, using the alignment tools to make sure the lines are perfectly spaced. (One way would be to copy paste a bunch of verticle lines, align, then rotate to the desired angle) Turn on Smart Guides (ctrl-u), then use the rectangle tool to draw a rectangle across the section of the pattern. Start the rectangle on one line (smart guides will help make this precise) and make sure the rectangle corner on the same horizontal plane as the first point ends at another line. Make sure the lower points also end on lines. Make the rectangle no stroke and no fill and send to the back. Delete lines that do not cross over or touch the rectangle. Select all and define the pattern.
Actually, after posting the above, I ran through the steps and found that my tiles were not perfect. By using outline view and working zoomed in I was able to get them very near perfect.
Generally, there is a better way to create patterns (Provided by Teri Petit) using the Effect > Distort and Transform > Transform palette, but for your type of pattern, the above is the best way.

How Best to View/Edit Moiré on Striped Shirt

Hi, we're preparing images to send to a couple different printers (we don't know who - one is a magazine, the other a catalog printer). These particular images have a gentleman wearing a blue & white pinstriped dress shirt. The client has asked us to ensure there is not a moiré pattern when printed.
So I'm wondering the best way in Photoshop to both see the pattern properly, and then how best to tackle it.
The original files were Canon RAW files at 21MP, converted to DNG, then adjusted in ACR before opening in Photoshop as a Smart Object for final editing.
So we only see the effect when we zoom to odd percentages. And obviously the effect is worse at some zoom levels than others, especially smaller. At 100% the image looks fine.
- How should you be viewing an image in Photoshop to get an accurate representation of the moiré pattern that would be produced when running on press? It's hard to fix something when you don't know what it actually looks like.
Secondly, I found a couple tutorials on how to remove the problem, but these seem to be geared toward color moiré patterns and using LAB to fix. The patterns here are not color moiré patterns, so I suppose that means they are luminance patterns.
- Any good experience or tutorials on how to approach this? Do we just blur the shirt or decrease the contrast (make it a blue & light blue/grey shirt instead of blue/white)?
Thanks. I just need a little direction here to get going.

Someone else had a similar problem:
http://forums.adobe.com/message/13764#13764
I don't know if this will help you because there seems to be a lot of technical jargon used rather than an explanation of a straightforward approach. The thread does mention a third party tool as well as a Photoshop plug-in.

Has anyone had experience with the new moire slider under the adjustment brush in LR4?

There's a new moire removal tool under the adjustment brush in LR4. In the near future I expect to have photos that contain moire patterns. Has anyone used this tool yet? I'd like to get an inkling as to how effective it is.

There is an example of moiré on the Nikon Imaging site for the D800E.
http://imaging.nikon.com/lineup/dslr/d800/features01.htm
I was able to reduce the moiré significantly, but not eliminate it with the Lightroom 4 adjustment brush. I haven't found any software solutions that can completely repair moiré. The Lightroom 4 feature seems about as good as any I've tried.

Clothing pattern distortion in Elements 10

When moving images into PE 10 for editing, patterns on clothing get distorted (stripes, checks). These are fine in other programs after downloading from the camera. They are also fine in the PE 10 RAW editor, but distort when moved into the editor. It does not seem to be just a display issue as they also print with the distorted patterns. Any thoughts on how to correct or avoid this from happening?

I found this method somewhere but never actually tried it.
1. Select the area showing the moire pattern; feather 1 or 2 pixels.
2. Layer > New > Layer Via Copy.
3. On new layer, use Gaussian Blur filter and starting with the slider at the far left, drag it until moire pattern disappears.
4. Change blend mode on this layer to Color. Supposedly, the moire pattern will be hidden by the blur and the object will look normal again.

Morie Patterns, how to get rid of them?

is there any photoshop trick that will kill off a moray pattern that sometimes happens when a photo is printed?

Moiré patterns in scans can be avoided
http://www.fho-emden.de/~hoffmann/scan121200.pdf
but it's mostly impossible to remove them.
Rare cases how to do this are discussed in Dan Margulis,
Photoshop Lab.
I'm scanning toner or inkjet or offset prints (yes, I'm
the copyright owner) by 600dpi or ppi.
Then I apply as much Gaussian blur as necessary to make
the scanned printed dots/spots not distinguishable.
After that one can downsample bicubic, for instance for
300ppi.
Scanner's descreening isn't reliable, IMO. It has to
be tested actually. According to tests a while ago,
one had to tell the scanner software the assumed line
screen frequency.
