HIGHLIGHT HOT & COLD AREAS

WHEN I CLICK ON THE HIGHLIGHT HOT & COLD AREAS,IN VIEW TO TURN IT ON.
EVERY PHOTO I GO TO ( IN ANY PROJECT OR ALBUM ,IT`S GOT THE HOT IN RED WHICH CAN BE ADJUSTED )
BUT THE WHOLE PHOTO, PHOTO`S GO BLUE WHICH MEANS I CAN NOT ADJUST THE COLD SPOTS.

Hopefully not telling you to suck eggs here but it might be worth watching a few of the tutorials that discuss image editing and adjustments, there are videos on all of the processes you need to understand in order to manage your highlights and shadows. Start at the top and work your way through them, made a world of difference for me.
http://www.apple.com/aperture/tutorials/
Also you will find a plethora of information here, specifically a pdf on "performing adjustments"
http://www.apple.com/support/aperture/
Hope these help you to understand how to manage the highlights and shadows, hot and cold functions.

  • Color problem - Hot & Cold areas

    I have downloaded a trial version of Aperture 2 and have been familiarizing myself with its various new features. I played with the preference settings and now my photos are showing "hot" and "cold" areas even after I reset the sliders to 100% for hot and 0% for cold. I have moved the sliders to all possible positions to no avail.
    Any suggestions?
    Thanks

    In your menu bar go to View->Highlight Hot & Cold Areas. Select it to remove the check mark and turn the feature off.

  • Hot and Cold area viewing confusing me...

    Hi Everyone,
    I've been using Aperture 2 since it came and I'm liking the workflow and integration with the rest of OSX. Today I stumbled upon something confusing. I was playing with the display hot and cold areas option and was finding that when I measured the hot areas with the loupe, that the color values weren't actually blown out...
    For example, I had a picture of a rose that when zoomed in, I could see the detail in the petals but was still being flagged as blown out. When I did a loupe rgb read on a 1x1 pixel point, I found that the red value was around 211...I thought that hot areas are 255?
    Maybe I'm confusing what "hot" means. I've even seen cases where the master image is flagged as having more hot areas even though it is less saturated and exposure level is lower.
    Can something be wrong with the hot/cold area function? Can anyone give it a try and see what kind of values they are seeing with the hot and cold area viewer?
    Thanks.

    Hi stjuste
    re Maybe I'm confusing what "hot" means. I've even seen cases where the master image is flagged as having more hot areas even though it is less saturated and exposure level is lower.
    Thought I would check. Used a pic of a dancer at night with firebrands. Pic looks good as I shot it.
    Measured the "Hot Spot' at 255, and some others at a lower value. The manual says:
    Images may occasionally have overly bright areas where color information about the
    area is beyond the standard limits of the Aperture working color space. For example,
    white areas in an image brightly lit with direct sunlight, or bright flashes off a water
    surface, may be so bright that their color is outside the working color space. In addition,
    images may occasionally have black areas where color information about the area is
    below the standard limits of the working color space. Aperture can display these “hot”
    and “cold” areas of an image with tints on the image to help you identify hot and cold
    areas. You may be able to adjust these areas and recover highlight and shadow detail
    identified by the hot and cold area overlays by changing the exposure, the recovery, the
    black point, or the gamma setting of the image.
    This maybe of help.. maybe not. Probably like you I set up the pics how I want them not what any program tells me.
    Interesting though. I will do a bit more checking.

  • Toggle on "Highlight Hot and Cold Areas"

    Aloha all.
    When ever I toggle on "Highlight Hot and Cold Areas" my image turns solid red. I know I must have a setting turned on or set too high but I can't figure it out? Anyone else with this problem? Solutions?
    Using Aperture 2.1

    In Preferences->Appearance, see what the hot area display threshold is set to. It should be 97 or higher.

  • Highlight hot and cold areas

    When "Highlight hot and cold areas" is turned on I often get some blue outlines in a photo, but when I press "Z" (zoom) they disappear. What is going on?

    Could be a number of reasons for this but nothing to worry about. You could try looking at the hot/cold threshold levels but you need to remember smaller images can't hold the same amount of data as large ones. Edge sharpening for example, on the large scale may contrast 10,000 pixels along a 1 inch line to the full size image. Now think what has to happen when the image is shown as a 7x5. Think of it in terms of Bit Depth. With 1 bit there is no grey area and choices have to be made about what to show. In this case it is not a perfect copy of the full size image. Allan

  • Highlight Hot and Cold toggle turns entire Image RED!

    Hi,
    I'm curious if anyone has a solution to this issue. I'm using Aperture 2.1.3 on a Macbook Pro running OS Version 10.5.7. I shoot Nikon RAW files and a while back when I hit the ever helpful Option-shift-H (to toggle the Highlight Hot and Cold feature), I end up with the entire image turning red (Hot). Now the histogram is fine, I just can't fine tune the hot and cold areas with the feature. . . I've tried reloading Aperture 2 from the original disk (I did not delete the original copy firs in fear of loosing my images).
    This feature worked fine until about 6 months ago- it probably stopped working during one of the updates. . . The "creative" at the apple store scratched his head and suggested I post here for a solution. . . Any help world be appreciated.

    In Aperture try this:
    Go to Preferences (cmd+,) -> Appearance
    Then set
    Hot Area Display Threshold to 100%
    Cold Area Display Threshold to 0%
    You might have set hot to 0% which would cause all parts of the image to appear red.
    Just play a bit with those sliders to get what you want.

  • Turning of Shadow (Cold area)

    I was one of the first buyers of Aperture when first introduced. I did not like many aspects of v. 1 (library, slow performance) so I migrated to Lightroom. When Aperture 2.0 was introduced, I downloaded the Trial and loved the new version so much, I purchased the upgrade.
    One thing I do not like about v2.01 is I can not figure out how to leave on the blown Highlights but turn off the Shadow (cold) area. I just find the blue tint so distracting when adjusting white balance. Has anyone found a way to disable only the Shadow (cold areas)? Lightroom gives you the choice of leaving the shadow area turned off while having the Highlights on.
    I have posted a comment about this in the Aperture feedback area.

  • Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold  backup ?

    Hi Friends,
    Is it possible to Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold  backup ? ( as i would like to perform Point In Time recovery)
    (or) The only way is to use RMAN convert as mentioned here  - Transporting Data Across Platforms
    (or) Is there any other method (except exp/imp and data pump)
    Regards,
    DB

    HI
    his post describes the procedure required to migrate a database from Windows to Linux using the RMAN Convert Database command.
    Both Windows and Linux platforms have the same endian format, which makes possible to transfer the whole database, making the migration process very straightforward and simple.
    To migrate between platforms that have a different endian format, Cross Platform Transportable Tablespaces (XTTS) needs to be used instead.
    List of Steps Needed to Complete the Migration
    The migration process is simple, but as it has several steps it is convenient to be familiar with them before running it.
    1. Check platform compatibility between source and target OS
    2. Start the database in read only mode
    3. Check database readiness for transport from Windows to Linux using DBMS_TDB.CHECK_DB
    4. Check if there are any external objects
    5. Execute the Rman Convert database command
    6. Copy converted datafiles, generated Transport Script and Parameter File to Linux
    7. Edit the init.ora for the new database
    8. Edit the Transport Script and Parameter File changing the windows paths to Linux Paths
    9. Execute the Transport Script
    10.Change the Database ID
    11.Check database integrity
    Thank you

  • Acrobat X highlight the bookmarked area of a pdf

    How do I make Acrobat X highlight the bookmarked area of a pdf when I select that bookmark?

    If I have 10 bookmarks on the same page, I want the text I selected when I created the bookmark (or the text that is bookmarked because it was a Heading style in Word and I chose to have the styles be bookmarks when I created the pdf) to be identified easily on the page. When I click the bookmark in the bookmark panel on the left I am moved to that page, but the specific area of the page is not identified in any visible way.

  • Conditional Action using hot/cold state to open/close toc

    I'm trying to create a button that will open/close the toc and when clicked will toggle the state of the icon/button from hot/cold.  Basically using an icon with a transparent smart shape as a button.  when the button is clicked the toc will open and the icon will change to the hot state (hiding the cold state icon) then when clicked again the toc will close and the icons will switch back.  I have my action set as shown in the images below.  Any insight would be greatly appreciated.

    Did you read this: Toggle Shape buttons - Captivate 6 - Captivate blog
    Scenario 4 is what you want: have two shape buttons, and use a standard advanced action for each of them.

  • On a map, is there a way to highlight a particular area?

    In using Adobe Acrobat, is there a way to highlight a particular area on on map in a different color?

    One thing you can try is the polygon markup tool (Comment > Drawing Markups) to define the area. You can set the fill color to the highlight color you want and then decrease the transparency value to something like 50%.

  • About hot & cold backups in rman

    Hi all,
    I've found out that with rman 9i the following script:
    - shutdown immediate;
    - startup mount;
    - backup database plus archivelog;
    - alter database open;
    is what I need for a cold backup; somewhere somehow I've caught a glimpse about
    this script
    - backup database plus archivelog;
    which 'should' be able to produce a reliable hot backup, but actually Oracle docs
    is not crystal clear on this point: I'd rather ask if:
    a/ would "backup database plus archivelog" create an usable full backup on
    a 9i archivelogged db?
    b/ would the same statement work on a 8.1.7 archivelogged db? (yes, the syntax is different...)
    hope somebody may shed some light
    thanks for help,
    daniele rizzi ([email protected])

    backup database plus archivelog; is a 9i RMAN command so it cannot be used in 8i. Here is what it does as stated in the Oracle9i Recovery Manager User's Guide and Reference:
    Backing Up Logs Using BACKUP ... PLUS ARCHIVELOG
    When backing up objects other than archived logs, you can specify BACKUP ... PLUS ARCHIVELOG to include backups of archived logs. The command performs the following sequential actions:
    - Runs the ALTER SYSTEM ARCHIVE LOG CURRENT command.
    - Runs BACKUP ARCHIVELOG ALL. Note that if backup optimization is enabled (refer to "Backing Up Files Using Backup Optimization"), then RMAN skips logs that it has already backed up to the specified device.
    - Backs up files specified in BACKUP command.
    - Runs the ALTER SYSTEM ARCHIVE LOG CURRENT command.
    - Backs up any remaining archived logs generated during the backup.
    From what I read it backs up all current archivelogs, backs up the datafiles, and backs up any remaining archivelogs created during the datafile backup. It basically makes it easier to backup the archivelogs by not having to issue a archvielog backup before and after the datafiles to ensure all archivelogs are backed up.

  • Hot / Cold Backup

    hi.
    Plz tell me what is hot and cold back up. their difference and usage.
    thx

    A database backup when database is shutdown state is reffered to as cold back up,while a database backup when database is up and in operational state reffred to hot backup.
    cold backup also refer to offline/consistent backup while hot backup refer to online/inconsistent backup.Their usage as above statment showing that ,if yours database does not go for 24 x 7 then go with cold/offline/consistent backup strategy.Cold backups are a reliable piece of any backup strategy cause as i mentioned consistent (consistent=clean not fuzzy),whenever you go to take cold backup first you will have to shutdown the database immediate which cause termination of any active transaction and make them rollback,oracle flush all dirty block from buffers to data file after rolling back any incomplete transaction,a full checkpoint occurence which cause to synchronize alls the CKPT SCN among the database file header as well to control file.Everything is consistent at the time of clean shutdown.
    if you cant afford any break within yours business domain and you have to go with 24 x 7 then you will have to go with online backup , for online backup you will have to turn on the archive mode of yours database which take care of any fuzzy block to be consistent.With online i would recommend you take atleast one time cold backup within a week if possible to make yours life easier.

  • HP dv6500z Notebook: Power brick gets hot, HD area gets warm.

    Hi:
    I have an HP dv6500z notebook.
    Is it normal for the power brick (suppy) to get hot ?
    By hot, I mean that it is warmer than "warm".
    You wouldn't want to keep you hand/fingers on it for a long time.
    Similary for the Hard-Drive area and other area on the front of the notebook:
    i.e., the areas to the left and right of the trackpad.
    These two areas were warmer when I had the notebook sitting on top
    of one of these Targus  "cooler " stands that you place the notbook on:
    it has two fans built into it to pull  heat away from the notebook.
    Thank you

    No it is probably the biggest online marketplace for car parts and computer parts and other stuff. Think of it as a huge swapmeet with some retail stores mixed in...virtual of course.
