Aperture and Canon 20D

I am using Aperture with my Canon 20D and I notice that really bright areas in the RAW file have halos in Aperture. And, the quality of the conversions do not seem that great. I am especially put off by the poor sharpening abilty in Aperture. Can anyone help me? I make money with my pictures, but no one is going to want to buy these poor things.

HI,
I'm not sure what to suggest for you on this. I'm a professional photographer, using a Canon 1Ds MkII and a Canon 20D. I have no problems with either camera and Aperture RAW conversion.
Here are a few things you could try, however:
1. Check your histogram to be sure that your image is not "blown-out." If so, dial the exposure down;
2. Check your sharpening and chroma blur settings to ensure that they are not to strong. You should examine your photos at 100% magnification to check this;
3. Check to see whether you have onscreen proofing turned on; and, if so, check to see what profile you are using. You may need to turn it off or to use a better/different profile;
4. Lastly, be sure to have all the latest updates installed on your machine, i.e. Tiger 10.4.7; Aperture 1.1.2, etc.
Not that this is much comfort, but, I can assure you that Aperture works perfectly well with a Canon 20D and its RAW files. This seems to be an isolated event, which is most likely fixable.

  • Aperture and Canon 5D with wireless adapter

    I have a 15" macbook pro, and I want to get a 20" iMac to do this, if I can, but when I shoot in the studio, I use my wireless adapter on my Canon 5D to transmit my photos to a Mac. Is there a way that I can use aperture to monitor a directory, and display the new photos durring a shoot, so I can review them right away. I can use the canon software when im teathered, but defeats the wireless adapter, and I really love aperture.
    Thanks!

    Go here:

    That should do it.

  • "Canon SLR EOS 40D"  *Aperture and Canon's CR2 RAW files not supported.*

    Hi,
    I just started playing with Aperture, and with my brand new *Canon SLR EOS 40D* camera. One problem, Aperture is not recognizing the RAW file format. I am using RAW Fine**-L. Even with that it doesn't even see the JPG shots in Aperture. Went to the Canon site and it shows CR2 format. IPhoto 08 sees the JPG files just fine, It also sees the RAW files just doesn't know what to do with them. I know that RAW files are not supported on IPhoto 08. The camera is only been out a few months, but still lost on why Aperture doesn't support the format. Maybe I am missing something. Anyone have any ideas?
    Thanks in advance....

    For some reason or another Adobe Photo Shop 7 is no longer supported in Leopard. When you lunch Photo shop 7 in Leopard. You get "An unexpected and unrecoverable problem has occurred because of a Program error. Photo Shop will now exit." even if you reinstall the program, still you get the same error. Photo Shop 7 is Not the latest and greatest, but in most cases, that is all you need. Not sure if they plan on a fix, so for now I put that program on a shelve.
    Hope that helps

  • Aperture and Canon 7D

    I am thinking about upgrading to a canon 7d. I read how there was a problem with Aperture reading RAW files, especially with red. I currently use Aperture 2 and dont want to buy the 7D if I am going to problem with Aperture.
    Has the problem been fixed? Any suggestions?
    Thanks

    This is probably going to sound really weird, and shows Aperture still has some issues it needs to figure out, but....
    On one of your high ISO indoor 'red' shots, add a vignette, but set both sliders to 0, effectively removing the vignette that is being added.
    Yes. I'm serious. This completely changes the red casts, and kills the nasty posterization I see on my system.

  • Aperture and Canon 40D RAW

    When will Aperture support RAW from my Canon 40D?
    In the meantime how should I handle my RAW images? Can I import them into Aperture now with metadata attached and when the support is there all my photos and metadata will appear?
    Any help is greatly appreciated.

    The first question has been asked many times in the last 4 weeks and there's no answer. Ask more and Apple will lock this thread.
    Second question. If you shoot RAW only, Aperture will import the file, and you won't be able to see it or work with it. You can export it to use Canon's DPP, Photoshop or other available converter to process it, save it to TIFF or JPEG, and then reimport to Aperture for now.
    If you shoot RAW and JPEG, Aperture will import both files, but it's not apparent where the JPG file is. Control-click or right-click the grey square thumbnail or the reddish main window, and click "New Version from Master JPEG" to reveal the full-resolution JPEG image the camera took.
    When OSX starts supporting 40D in the future, those RAW files will automatically be shown inside Aperture.

  • Aperture and Canon 5dMark11 Raw

    I used my new 5d recently and used the combo sRAW1 and JPEG to be imported to Aperture (latest version). It seems Aperture only works with full RAW and not the other RAWs on the Canon. I called Canon but they only suggested importing using their supplied software DPP. It works but I'd like to know about Aperture.
    Any thoughts on this being so or am I missing something?
    Thanks,
    John

    Most if not all third-party raw convertor programs will only work with the full raw file from a dslr. They won't work on the sub-variations like sRAW. For that, as Canon said, you have to go to their software. IOW, if you stray from the full raw format you have to go to you the camera manufacturer's software.

  • Slight bands using Aperture and Canon 30D

    Hi guys,
    I have some problems using Aperture, developing/converting RAW files from my Canon 30D.
    Unfortunatly I have bands in my pictures. Means that there are slight differences in the brightness of the files, which will give horizontal bands.
    We already tested these files in other RAW converters like Capture One, RAW developer and Adobe RAW Converter.
    Only the Adobe RAW Converter doen't show these bands in the RAW file, so we think that these are probably are errors coming from the camera chip, which Adobe already knows and fixed by their converter files.
    I only see these bands on my concert pictures using ISO400 to 800. This will probably explain the errors coming from the chip.
    So my question is, does anyone of you saw the same things in your pictures?
    I have and developed image where you can see the problem. I also can send you the original RAW file to check for the problem.

  • Aperture and Canon 5D mark II import problem: copyright and author metadata

    After importing RAW images to Aperture, I missing my name and copyright info in metadata, everything els is there; lens, focal length, shutter sped... I try several methods from camera direct, from memory card, using EOS software to HD and to Aperture. Nothing works. Did anybody have same problem?

    Ah. I didn't know that.
    This type of information is defined typically in IPTC, not EXIF. Aperture probably ignores those EXIF fields; in general if it gets EXIF data it doesn't understand, I think it ignores it.
    As to your other comment about making this data unmodifiable -- it's not really possible to make it immutable. EXIF in general is a lot harder to modify than IPTC, but unless the file is encrypted and self-checksumming, a person with a sector editor (or an application designed to change EXIF) will get around this.
    I don't think there's yet a standard way to really "protect" full-sized image files, at least for JPEG or TIFF files.

  • Aperture and Canon Pixma MP620

    Hi All,
    this time have some problems with Aperture that I'm just using since few days. My problem is the following: when i try to print a picture using my MP620 it produces images with strange vertical stripes (especially visible near the black areas) that affects all kind of print format.
    This issue doesn't happen in iphoto that prints without problems the same images (so printer problems are discarded).
    I use sRGB on my camera and the same is for my monitor: I've also calibrated it again to be more sure (so Color Sync settings problems are discarded too).
    I've read somewhere that the output bits available could be at the origin of this problem. My printers specifications about color depht are the following:
    grey depht 16 bit (internally)
    grey depht 8 bit (externally)
    color depht 48 bit (internally)
    color depht 24 bit (externally)
    I've got an Intel with Snow Leopard and my printer's drivers are all updated to Snow.
    Hope that some Guru here could help me!
    Ciao,
    Mariano
    P.s.: Have the same problem with Lightroom2 but the stripes are less visible (printer output was set to 16 bit)

    Hi All,
    just to update the community: I've made a rollback of the printer's drivers (I was just using the Snow Leopard ones) to the old Leopard version and now Aperture seems printing perfectly! I think this is the first case someone is answered his question by hiself!:-)
    Bye bye

  • Aperture and Rebel XT

    Searching the forum I found a threat back from last year talking about the 350D and the XT not being supported, just trying out Aperture at a friends place I found that the "preview" works fine with the Canon, but once important it gives me an "unsupported file format". ????
    Ironically enough, with the latest update to iPhoto the XT finally is supported in RAW, but now it seems the "Pro" Product doesn't support it.
    Anybody got an idea what gives?

    I support a small office. They have aperture and canon eos 350D's for shooting marketing shots. They are not high end photograpghers. They have a copy of aperture to manage the RAW files. Now firsty it is the European model.....so in Aperture 1.0 and 1.01 it was not supoorted so i did the Raw.plist change and had no problems.
    Now i had a call the other day...strange issue. The camara had a fault it had it insides replaced and now the camara is called Canon EOS 350D(firmware 1.0.3) it was called Canon EOS 350D Digital before. So all th eold images from same camara are fine. Any new imports are shown as unsupported.
    I have tried to add the profile in Raw.plist with new name with no joy. It looks like when using Property list manager that apple have used a string to link names to profiles ie >
    jap name : Canon-EOS Kiss Digital string Canon-EOS DIGITAL REBEL XT and does this a few times.
    I must admit i am at a loss now just cannot get it to work. I have now loaded the old Raw.plist file from 10.4.6 update.

  • Bug exposed when comparing Jpeg and RAW Photos taken with Canon 20D?

    I'm using iPhoto 7.1 to manage my photos. My Digital SLR, the Canon 20D, can be set to save photos as both RAW (CR2 files) and Jpeg (JPG files). Both of these files can be imported into iPhoto with no problem.
    The problem that I have is that these photos that should be identical, have two major discrepancies.
    1. Their resolution are NOT the same. (3504x2332 for CR2, 3504x2336 for JPG)
    2. The colors appear different (CR2 appears reddish, JPG appears normal)
    Interesting to note: if I export the same CR2 file out of the iPhoto library (export it as Kind='original'), and open it with IrfanView running on Windows 2000, the photo is viewed with the expected resolution of 3504x2336 and the color appears normal (i.e. not reddish).
    I'm a new Mac user, and relatively new to digital photography, so any advice or suggestions would be appreciated! I've heard of color profiles and adjustments, but I'm not sure how that works. Perhaps I could be pointed to a HOWTO type document?
    Cheers

    OK, next RAW files again.
    These hold the data the sensor 'saw' when you took the shot together with 'metadata' such as aperture, shutter speed, white balance settings, ISO setting etc - lots of data in fact.
    Most programs do not alter RAW files at all - they are the digital negative and should not be altered.
    The latest iPhoto treats all newly imported photos in this manner - RAW/JPG or other format. It keeps a copy of the original in a folder called originals, and any edits/crops you make are applied and saved either as a modified JPG or TIFF. This non-destructive editing is a great feature that many RAW editors allow so you can go back to the original image if you mess things up. Applying the principle to JPGs etc is equally as important.
    Canon's Digital Photo Professional is a free RAW processor program you can download from their site - certainly worth a look, but you may well find iPhoto simpler if not as flexible. On Windows, not sure about Mac OS, DPP does actually alter (or add) some metadata to RAW files - it doesn't alter the 'sensor data' but somehow embeds edited values to the RAW file so they display as edited next time - you can go back to original but I doubt other software will understand these tweaks.
    Digital cameras are getting better and better at getting white balance etc correct, however RAW files are great mainly for two things.
    Firstly - in camera white balance settings are simply those applied to JPGs the camera produces. Set it to fluorescent and take a shot of a cloudy scene and the JPG may look awful. With the RAW you can change the white balance after the event and is a real image saver. I particularly like software that lets you use a 'dropper' to choose a neutral grey shade on the image to set the white balance.
    Secondly - over/under exposure. As RAW files hold more light intensity detail you can often bring out shadow detail from underexposed images or recover blown highlights from images that are unusable as JPGs. There are limits to this latitude of course.
    In camera JPGs are often all you need - the RAWs just give added flexibility.
    Next thing I'd say is not to get too hung up about profiles at this stage.
    Yes, you can pay for generic profiles or even expensive personalised profiles for the 20D - there are some gains in compatible software (sometimes the profiles are designed to work with particular software!). Not necesarily huge gains though, so I'd say keep it simple to start with.
    If there's one thing it's worth profiling, then it's your monitor.
    I often use the analogy of a TV with a video still image from DVD or VCR.
    Say you adjust the brightness/contrast/colour/sharpness of the TV then the image can be made to look wildly different on different settings.
    However the actual image being displayed is not itself altered at all by the DVD player or VCR on pause. Turn the TV off it goes black, but the DVD/VCR still outputs that same image. It's just displayed differently or not at all!
    Translate this to editing photos.
    The RAW or JPG will be processed by iPhoto according to a particular colour space, say sRGB or AdobeRGB - now how on earth do you know that the monitor's brightness/contrast/saturation are at the correct level to display the image correctly? Is it brightnes 50%/75%/20%?
    The answer is the monitor profile which tweaks the output of the monitor towards a preset calibration - this is for a given brightness/contrast/colour setting (not all monitors have exhaustive adjustments but some do). Generic profiles which come with Macs are better than nothing, and indeed often quite close to an individually calibrated monitor profile.
    You can however calibrate your monitor either by eye or using a hardware accessory.
    Open your System Preferences folder and choose Displays.
    Click the colour tab and remember the profile name highlighted!
    Click on any others to see how different profiles affect the display - the other profiles will invariably be wrong for the monitor but they show the effect.
    These other profiles DO NOT make you system display an image say as sRGB or AdobeRGB - what they imply is that the monitor can display the range of sRGB or AdobeRGB - it can't! It can display what IT is capable of displaying.
    It is the image profile that makes software display it in the sRGB or AdobeRGB or other colour space. The monitor profile allows the image to be displayed more accurately by mapping available colours it can display or close fits to the one's the image contains.
    There is a Calibrate button in this tab which should help you Calibrate your monitor by eye (I think I've not used it).
    You can also buy hardware accessories to accurately calibrate your monitor (I use an EyeOne Display by Gretag Macbeth - older version - there are far more expensive and also reasonable cheaper options out there). The hardware devices basically cycle through a display of 'known colours'. The device's software knows what colour it's trying to display, the device usually hangs over the display and measures what's actually displayed, then reprograms the way the graphic card displays colours and also creates a custom monitor profile - this process of calibration optimises your monitor's display.
    You can also calibrate or get custom printer profiles made to optimise printer output, but you won't be doing that. Some online photo sites do however supply profiles which match their photo printers so you can tweak your images to match output on their hardware.
    Most photo sites that the public use however will assume that the images are sRGB. If you send an AdobeRGB image for printing it may be treated as sRGB and printed incorrectly if that photo printer's software doesn't take account of embedded profiles.
    I said it was complex and confusing!
    Continued again!

  • Aperture now says no images to import on my Canon 20D

    After working just fine for months, now suddenly when I connect my Canon 20D to my Mac, Aperture launches but says there are no images to import. I'm able to use Image Capture to import the *.CR2 files and can them move them into Aperture, but I don't understand why it suddenly stopped working.
    When it stopped, I was using it to import from one memory card, finished that one and put another card in the camera, it said there were no images on the card and continues to think so, even after importing using Image Capture, erasing the card and shooting more pictures.

    Curious: Are you formatting the card in your camera or using Image Capture, etc?
    You may already know that formatting in camera is the way to go to avoid any problems.

  • Aperture 2.0 and Canon XSi (450D)

    Does anyone know if Aperture supports the new Canon XSi model? Or if there is a list of supported cameras for aperture? iPhoto keeps rejecting the CR2 file format from my XSi and I'm looking for software that I can edit my RAW images.
    Thanks in advance for any input,
    Regards,
    -Steve

    I don't know that it's necessarily any harder for Apple to support the XSi than any other camera.
    Supporting RAW formats means carefully analyzing proprietary file formats and sensor products and modeling them to provide consistent results across many different formats. It's not is it merely hacking up a file -- you want those raw sliders to work as expected and deliver beautiful results.
    Combine this with the fact that camera companies tend to release many new products all at the same time, and it's not a fast process.
    By way of comparison: in late August 2006, Canon announced the XTi. Samples were available at Photokina in early September. I purchased one the day they came in, which was late September -- around the 24th or so. Full, flawless XTi support was added to the operating system (thus for both iPhoto and Aperture) in early November. That's a turn around of about 2 months from announcement to support, and of about a month and a half from release to support. I'd say we have another month or so to wait.
    In the meantime, it's possible to use an external RAW converter, convert to DNG or 16 bit Tiff (I'd use Tiff if you have the space), add the converted files to Aperture and store them on disc/network along side the RAW originals. Then, once support is added, you can add your originals, stamp the changes you made to the converted versions to the originals, and then remove the conversions. Again, this is a workaround for a month or so, and is the price you pay for being on the bleeding edge.
