Hot Pixels Show in Aperture, Not ACR3.3

I have a 11.75 month old Canon 20D and while working in Aperture this week just noticed some bright red pixels and some less bright green pixels in every single frame shot at exposures longer than 1/2 second. This was a complete surprise since I had never seen these before, but I was using Photoshop CS2 and Adobe Camera Raw 3.3 to process most images from the 20D.
Further to my surprise, I noticed that when I first open a file in ACR, the initial preview image shows those hot pixels-- but when the ACR-processed preview renders and displays (about 1.5 seconds), those hot pixels disappear! And, when those files are opened in CS2 the hot pixels are not to be found. That's why I've never seen these until now.
I've searched this forum and several others out there and have some understanding about hot/dead pixel mapping, but this auto-removal thing by ACR3.3 is unexplained.
So that leads to the question- could Aperture perform the same mapping to remove these bad pixels? (I plan to submit that via the feedback path in Aperture)
Has anyone else experienced this?
I now have only 1 week left to get my camera into Canon to have them "map-out" those hot pixels but having an alternative in Aperture when new hot pixels develop would be nice.

Smoothing is what's going on. Believe me, if Adobe had something like "automatic dead pixel removal" the would be marketing it heavily. I did some experiments recently with an original high ISO, wide dynamic range image from a Nikon D200. Looking very closely at the real, actual noise in the shadow areas, Aperture showed what I would consider a normal amount of noise and it was very random and well distributed and looked a lot like film grain. I brought the same image into ACR3.4 with the same "non-processing", and when I looked at the area at the same level of magnification, I saw that ACR was doing a LOT of noise suppression, and the area looked very "globby", and areas next to it that were lighter looked "plasticy". Now this was pixel peeping at it's worst, at 200%, but it brought out a significant point. Aperture's default processing is doing less sharpening, and less noise suppression than ACR.
I suggest the reason you haven't been seeing the hot pixels in ACR is because they are being smoothed or averaged out.

  • Is Hot Pixel Reduction Still Happening in Camera Raw?

    Seems to me that in past versions of Camera Raw I was seeing pretty effective hot pixel removal.  Is that still in the converter?
    I was just processing some high ISO night shots and it sure seems to me that I see more hot pixels in the dark places than I used to in conversions.  But it could just be these images and the settings I am using bringing them out.
    -Noel

    Thanks, guys.  I think all is well.  The egregious hot pixels are being handled.
    I just did some very careful comparitive conversions going all the way back to Photoshop CS3.
    In the change between Photoshop CS3 and CS4 (ACR 4.6 and 5.7) there is a definite difference in the hot pixel handling, with more hot pixels showing in conversions from the latter.  Notably the detail level in conversions seemed to go up markedly at that time as well.
    However, it became clear to me that the reason I was seeing more hot pixels than I thought I should was that I was actually pushing the exposure up on high ISO night shots already, bringing out more noise than would be seen at default exposure levels.  In fact, without such enhancement the remaining hot pixels are essentially invisible.
    Here's a small portion of the same "boat parade" raw file converted with all these different versions, noise reduction completely off, and enhanced in brightness well beyond the levels I normally do just for illustrative purposes.

  • Aperture 3 RAW conversion and hot pixel problem

    I've used every version of Aperture since release, but I'm not very happy with the RAW conversion in Aperture3.
    My images from earlier versions have no hot pixel problems but if I update to the new processing I can see them.
    Single red or green pixel in the 100% crop image, that didn't show up before and also don't show up in LR.
    The images I'm importing are NEF files from a Nikon D2x.
    Is this a bug in the new RAW conversion for this camera?
    It makes all of my images now unusable through Aperture if I reprocess them?

    I haven't noticed the pixel issues that you mention, but I wasn't looking for that yet. Instead, my images from my Nikon D300 have been stressing A3 out as follows....
    I have been having new issues with A3 now. I bought A3 when it was 1st available and had all of the same issues that plagued some users, I worked through it and until recently have loved A3.
    While editing I noticed that A3 had a large number of my photos, about 30% of 34,000 images, labeled as being processed under an earlier version (A2). I decided to go ahead and re-reprocess the images, even though this step took a couple of weeks and countless crashes when I first purchased A3. Again, just over a week later, the images are now re-reprocessed within A3. And a new problem cropped up.
    My Macbook is...
    [img]http://jasonksepka.smugmug.com/photos/942470326_QzaME-M.png[/img]
    and when I open A3 and begin looking at my images, the program is slow to respond and when it opens an image I get a very unprocessed version of lines for up to 5 seconds before the image finally loads. The image and all edits do load, but the workflow is significantly effected and I would like to know why this is happening now, and how to fix it. Below is an example of what happens with each image.

  • Can Aperture not be set up to show a "Last Import" smart folder?

    I'm trying to make the transfer from using iPhoto to using Aperture.
    One thing I found really great in iPhoto was the smart folder that was simply set to show the last import, no matter when that import was done - whether it was today, yesterday or 6 months ago.
    The reason I found this so handy was because I set my iPad up in iTunes to only sync the photos from that Last Import smart folder, rather than all my photos.
    That way, every time I synced my iPad, I always had my most recent photos on my iPad, no matter when the pictures were taken.
    Now with Aperture, I cannot see a way to create anything similar. The best I can do is to create a smart folder with photos imported within the last month, let's say.
    But the problem with that is that if I haven't imported any new photos for over a month, then the next time I sync my iPad, then all my photos will no longer be on the iPad.
    If I create a longer timeframe, to let's say 3 months, then I might end up with way too many photos trying to sync across, and that's something I don't want. I could end up with hundreds and hundreds of photos, and I don't have the free space to be able to do this!
    When I used "Last Import" with iPhoto, then I always only had around 50 or 60 photos, because that's just generally how many I usually imported at any one time. Sometimes it was more, sometimes less, but the average worked for me.
    So to sum up: Can Aperture not be set up to show a "Last Import" smart folder, regardless of date?
    Or alternatively, is there any way I could "hack" or "trick" Aperture into doing something like this so that I always have a managable amount of the most recent photos on my iPad?

    Hello Brett,
    that does not seem to be an easy probem as you discovered.
    Some Workarounds:
    You might to use a smart album rule "Import session is" instead of a date range, but that will not be automatic.
    Create a folder "recently added" and keep your recent projects inside that folder; create a smart album at the top level of that folder; move older projects somewhere else.
    Or enable the Photo Stream - that is the current replacement for the "most recently added" album; it will (is supposed to) always show the most recent 1000 images.
    If you are familiar with AppleScript, you can make Aperture run an AppleScript on import (Import Settings) to add your imported image to an album of new images. From time to time remove the older images.
    Sorry, but no really convenient way to do it..
    Regards

  • Aperture not showing up in app store

    Why is Aperture not showing up in the app store for re-download? I purchased version 2 and upgraded a while ago, and it works great on my old Mini, but with the Macbook Retina coming soon, I'm worried that I have to purchase again?

    How did you upgrade? From the App Store? Somewhere else?

  • Images pixelated in Aperture, not iPhoto?

    I have been importing all my images to Aperture from an external drive, and all is going well. My problems is some of my images are pixelated when viewing them in Aperture. When I open iPhoto though and view my Aperture library in iPhoto the images look normal. I have not imported them to iPhoto, I am just curious what is going on here? I am an Aperture beginner so I am lost as to why this is happening?  Hope that make sense. It is kind of hard to explain what is happening.
    Thanks for any help in advance,
    Christopher

    Re: Images pixelated in Aperture, not iPhoto.
    I am having a similar problem but instead of iPhoto, its Bridge.  The same exact photo that I opened in
    Aperture at 100% is quite pixelated yet when opened in Bridge, it is not.  I am using Aperture 3.2.2, on a
    MacPro 2x3 GHz Dual-Core Intel Xeon w/ 9GB Ram, running 10.6.8.  I thought it might have something to
    do with the graphics card.  I have the ATI Radeon X1900 XT.  When I copied the same raw file to my 13" Mac
    BookPro with a NVIDI GeForce 9400M Graphics card, the photo looked fine in Aperture.  Since Aperture is so graphics card intensive, is it possible that it needs a better graphics card?  If so, is there a better one I could install in my MacPro?
    Thanks for any help.

  • Why is my External Hard Drive not showing in Aperture 3.6 Import?

    Why is my External Hard Drive not showing in Aperture 3.6 Import?
    Only my computer hard drive is and I want to import from an external drive.  I have always been able to until I updated to Aperture 3.6 and Yosemite.

    Only my computer hard drive is and I want to import from an external drive.  I have always been able to until I updated to Aperture 3.6 and Yosemite.
    I had the same problem. On the folders on the drive with the Aperture library did show in the Import panel. After I clicked the computer icon in the upper left corner of the Import panel, suddenly all drives appeared.
    You can also try to drag the folder you want to import into the Import panel, to point the file chooser to the drive.

  • Aperture not showing (just black) newly imported JPEG files

    RE: Aperture not showing newly imported JPEG files.
    In fact its just black instead of the actual image. (see attached screen shot)
    When double clicking on this - i.e. to go to the edit mode, the image then appears.
    If I return to the viewing screen without changing anything to that image it remains black.
    If I make any kind of change to the image, the image will appear when returning to the viewing screen.
    Aperture seems only to have started behaving like this after update to OS X  10.10 (Yosemite)
    I have the latest Aperture 3.6
    Latest Digital Camera Raw 6.00 Build 761.5 and Digital Camera Raw Support 6000 Build 131.1
    RAW files (taken with same camera) are displayed without any issues.
    JPEG image files have been taken with a Sony RX100
    JPEG image files taken with the same device imported into Aperture before OSX update to 10.10 have appear to have no issues
    I cannot say if JPEG files taken with a different device have similar issues.
    All files have been been reprocessed to latest edition of aperture
    I have had other issues of other types of files (i.e. TIFF output  files 'unsupported image format' behaving oddly including inconsistent behaviour after having been processed by 3rd party aperture plug-in's -  although this has now largely been solved.
    I remember having similar issues of files behaving strangely in Aperture after last update to OS X (Mavericks) - forget how this was solved -  but I'm pretty sure it was not an issue involving JPEGS
    Many thanks

    ...this sounds very similar to the problem I had on a previous aperture update and I had a similar issue  -  to that - with the .tiff files output from RAW files and an HDR plug-in.
    In the first instance, I cannot remember for sure, but maybe it was something to do with not having the latest RAW File update for Aperture specific to that latest Aperture Update and specific to a Sony RX100 (or it could have been a Nikon d700).
    I found the RAW file update  -  I'm not sure it was being made available from the App Store -  and everything was fine.
    With the more recent issue, I'm pretty sure this was resolved by updating to the latest Photomatix HDR plug-in.
    So I'm just stuck on the issue with the JPEGs now.

  • Lightroom not fix hot pixels from my Nikon D7100

    Hi there.
    I have a problem with my cam D7100: there are tons of hot/dead pixels on the sensor.
    I am going to bring this cam to the service center.
    But I have a lot of images captured with this cam, and need to remove hot pixels from them.

    LR actually does more than find and repair 100% level "stuck pixels," it also finds and corrects low-level hot pixels and higher-level "random" hot pixels. The problem is that you have "many" higher level hot pixels and LR's processing algorithm thinks they're image data. A different raw processor may work better or worse. Feel free to "trial" any of them and report back here what you find. Even with my 600D set +2EV higher in exposure (ISO 100, 1/30 sec. versus ISO 200, 1/250) your noise levels are much higher. IMHO you've got a defective camera!

  • LR 3.4.1 does not filter hot pixels from Nikon D7000

    Lightroom has so far been able to filter hot/stuck pixels from my old D70s raws quite well. For some reason however, it doesn't seem to recognize them in raw files from my D7000 and noise reduction leaves them completely untouched.
    The camera doesn't really support mapping (except through potentially multiple multi-week customer support roundtrips), and the built-in noise reduction for long exposures effectively doubles the time per picture. It'd be really useful to have mapping from a static black frame in LR, or a despeckling/denoising method that picks up the "new and improved" stuck subpixels.

    There were reports of "hot pixels" when shooting videos:
    http://www.engadget.com/2010/12/22/nikon-d7000-firmware-update-released-cools-down-hot-pix els/
    ....and with still images:
    http://www.photosig.com/go/forums/read;jsessionid=awkf4asZE9kc0r15__?id=245003
    http://www.microstockgroup.com/cameras-lenses/nikon-d7000-sensor-problem/
    There is a firmware update to fix or minimize the issue with videos, but that won't help your RAW still images. I downloaded your image file and most of the hot pixels are actually groups of 3-5 pixels at 150-180 level (out of 255) viewed in PS. I'd return it if you can, or take it in for repair under Nikon warranty. I am sure Nikon is well aware of this "quality control issue" (i.e. bad sensor chips).....Not acceptable! I tested my less expensive Canon 600D at 30 sec. and ISO 1600 and found no hot pixels above 35, all of which clean up nicely in LR with minimal luminance NR.

  • Nokia Lumia 1020 with three hot pixels on the CCD....

    Okay, i have a two weeks old brand new Lumia 1020 and noticed that whenever i took a photo or record a video, i get an L-shape of three hot/bright pixels somewhere in the middle of the photos or videos themselves, which could mean these hot pixels are burned on the camera's CCD directly. I can also see them live on the Lumia's screen, though if i zoom in on the live view passed a certain level towards the maximum zoom, they vanish. But, on most zoom levels and of course when no zoom is used, i can see them clearly, unfortunately...
    The attached image shows these three L-positioned bright pixels...
    Also, check the video below for better understanding; i'm just shooting the black plastic frames in-between my two monitors, to get a dark area for easily spotting the three bright pixels. When i zoom in and out, you can see that passed a certain zoom point, they dissapear and reappear. Also, when i move the camera around, they follow along the movement. The video is a cropped-down version of the 1:1 1920x1080 original version, just to get a smaller file size: https://www.dropbox.com/s/g9zfcy3vivb1nku/HotPixel​s.mov
    So, i'm wondering...
    Is this serious hardware mulfanction problem valid for a phone replacement, or this is something that warranty may not cover ?!
    Thanks...

    It's hardly deep hacking. The repair facility opens the phone, takes out the camera module and puts a new one in.
    Your warranty does not entitle you to a full replacement unless the phone is not repairable (in genral) and this should be a painless and easy fix.
    While in some countries you would be entitled to a new phone if a fault is detected shortly after buying the device you said you bought it a week ago which would generally be too much time gone by for that so I anm pretty sure it's a repair.

  • Could I have some help identifying and fixing dead/stuck/hot pixel?

    Hello, yesterday whilst watching a movie on my Macbook Pro I noticed something on my screen, at first I thought it was just something stuck on the screen but it seems to be an issue with a pixel. I would appreciate help regarding identifying if it's a dead, stuck or hot pixel and any ways of fixing it. It seems to be smaller than what I had previously experienced (on other machines) dead/hot/stuck pixels to be and I can't really tell if it's white or a light blue. It doesn't show up on any colour other than greys and blacks.
    Also, is it likely that taking it to an apple store will yield results if it's still in warranty and I explain that as a photographer it's a very annoying thing to have on almost the centre of the screen.
    I hope you guys can provide me with some help, it will be much appreciated.
    Stefano.

    Welcome to the Apple Support Communities
    That's a dead pixel or it may be dust, too. In both cases, as your computer is in warranty, take it to an Apple Store or reseller and you should get the display replaced for free, even if it's only one pixel.
    I wouldn't be surprised if that's dust. I have seen a lot of cases related to dust in this forum, but it has got the same solution as the dead pixel

  • Aperture Not Recognizing Duplicates When Importing From iPhone. PhotoStream is Involved.

    Apple makes great software. Aperture is not some of it.
    Here's my setup:
    '11 MacBook Air OS X Lion
    Aperture 3.2.2
    iPhone 4 ios 5.0
    1.5 TB External Drive. Aperture Masters and Library reside there, separate from each other.
    I keep my photos in a structure such as: Aperture Masters > Year > Month > Date > original_photo_name
    I'm running into trouble with Aperture not recognizing what photos are duplicates when it comes time to import photos. My workflow is that I'll import photos every so often, leaving them on the iPhone, and delete them twice a year.
    ISSUE 1 (The Annoying One):
    Aperture is showing a lot of photos that have already been imported even if I select "Don't Import Duplicates". Aperture has done this for a long time. I know that when it comes time to importing them, it doesn't import the duplicates, but this is just a sign that something doesn't work very well. (Maybe it's because I switched to an iPhone 4S and then back. I synced all my photos, and then back again to my iPhone 4, so the sequential number of the photos remained intact. I don't think that's the problem though.). This is just a minor annoyance that shows that Apple can suck at software (remember MobileMe?).
    ISSUE 2 (The serious one):
    short version: Some photos on my iPhone won't sync to my Aperture library because it thinks they've been synced through PhotoStream. They are not in my Aperture Library or in my Aperture Masters in the filesystem. How can I fix this. What bloody file do I have to delete for Aperture to stop being confused?
    longer explanation: When iOS 5 came out, I was excited by PhotoStream. I had enabled it on my MBA, through iPhoto (I hadn't installed Aperture on it yet, as I was using an iMac to manage my Aperture Library). I believe it synced a bunch of photos from my iPhone, but then I stopped using it on my mac. Left it on on my iPhone. Installed Aperture. I initially enabled PhotoStream but swiftly disabled it once I was not sure how it would deal with photos being uploaded from my mac etc - just seemed like too much magic was going on. I then proceeded to sync my iPhone, not importing duplicates, and it synced a bunch of photos, but didn't sync some of them, displaying the following message:
    Any tips on how to fix this and be able to import those images would be greatly appreciated.
    P.S. - I thought that iPhoto might be causing the problem. I checked there and there were some images imported through PhotoStream, but not some of the ones which were not imported on Aperture. Putting that another way: the iPhoto library accounted for some of the images that were not imported, but not all of them. I deleted the iPhoto Library and tried reimporting with Aperture. Still no luck.

    I have precisely the same problem. Very annoying. Worked fine with iPhoto, borked with Aperture 3.

  • My new iphone-5 isight camera has 2 or 3 red hot pixels. Is that a normal?

    I bought (iPhone 5) 2 days ago and now I found out there's two or three Red color hot pixels on isight camera esp on rear camera in the dark. I just want to know other iphone5 has the same problem like mine or not.
    Please help me out.
    SamuelMei

    I suppose you could say I have/had the same problem.
    My battery life on my 11" MBA is similar to your situation. I fully expected that the technician would find nothing wrong, as battery life varies. A perfectly functionaing battery can yeild quite different run-time expectancy, depending on the nature of the use of the device.
    Some of the reposnders here have been using their experience with a 13" MBA, which has a much longer run-time, due to its higher battery capacity versus load ratio. "The 11-inch MacBook Air has a battery that lasts up to 5 hours, and the 13-inch model lasts up to 7 hours", according to Apple's battery testing protocol. The operative words in that description is "up to".
    Maybe I am coming on a bit strong here, but this is what I have found after owning 3 MPP's and one MBA, is that battery charge longevity is wholly dependednt on how much load you put on the components by the nature of the use of that computer. By saying your manner of use is "Safari only", doesn't tell much. Safari itself doesn't use much in the way of resources, but the plug-ins and support applications it may use can easily add to the overall amperage draw by a factor of many times Safari alone. That in itself can mean the diffrence between 5 hours, and 3. The manner in which you use Safari, the way users here use Safari,and the manner in which Apple tests Safari for baatery longevity, is probably qite different. I doubt Apple even tests Safari with Flash, seeing how they dont't even include it anymore.
    But hey, if Apple is willing to swap out the unit to give you peace of mind, and if it please you, then good for you! I hope that I am wrong about your situation, and all goes well.
    BTW, I am greatly pleased with all my Macs, especially my MBA, which gets 5 hours battery when I use it lightly, and 3 hours quite often.

  • How do I disable automatic hot pixel correction in ACR?

    OK - I'm really conused here...
    I just got a Nikon D800E and on my first day of shooting I noticed a hot pixel spot in my images in Bridge.  The when I opened the files in ACR, the hot pixel spot was gone.  Apparently this is a "feature" of ACR: it automatically replaces hot pixels with RGB values from neighbring pixels.  (So those of you who think you have no hot pixels, think again  - you might be shielded from the truth!  I find this fact very disconcerting, but that's a separate issue...).
    The problem is that I can't tell how many hot pixels there are.  Based on the image in Bridge, it would have to be spot of 20 - 30 pixels (maybe even more).  That's unacceptable to me, especially on a $3300 camera.  Sure, maybe a few hot pixels spread around the image, but 20-30 bunched in that one spot, that's unacceptable.
    However, I can't figure out how to disable the automatic hot pixel correction in ACR, so I don't know if the issue really is 20 - 30 hot pixels or if Bridge is just doing some type of sub-sampling that makes the problem look a lot worse than it is.  Furthermore, this concerns me greatly because I've been using a D200 for many years and have never seen a single hot pixel issue.  So that says to me that the sensor on my D800E has a bigger hot pixel issue than it should (I realize all sensors have some hot/dead pixels).
    So, any help on how to go about figuring this out?  The simplest solution is to disable the automatic hot pixel correction in ACR, but I can't figure out how to do that.  I'm guessing it's not possible.
    Thanks,

    What I can tell you, without a question, is that it was discussed at length in these forums during the earliest versions of ACR eight or nine years ago or so, and I remember participating in a discussion of the feature myself with other Pentax users in the Pentax SLR Talk forum on DPReview around 2003 or 2004.

    Interesting. It's possible that my camera does have a few bad pixels, but I'd never see them because I shoot RAW exclusively and Adobe Camera Raw maps them out on the fly.
    One of these days, when I'm feeling masochistic, I guess, I'll try the Pentax software to convert a test image. Or maybe not.
