Why use channels

I have worked in photoshop since photoshop 5 and even way back then I'd never gotten into the habit of using channels. At the time I think there were file size issues because I always used layers which would balloon out to quite large files, but I reckoned just get a bigger machine. These days with 64bit power is not an issue at all but I have been occasionally curious (like now) as to the actual benefits of using channels. Could anyone enlighten me.
<<topic moved to the Photoshop forum>>

I was having an issue with the Fuzz-Wah being too overbearing, so I used it on an aux track like a reverb, and was able to control how much wet signal there was by pulling up the volume on that aux.
I would suggest being creative. If you are adventurous, try doing some sound design. For instance, I had a distorted guitar that sounded great, but I wanted to have a little more in the background to give it some depth. So what I did was, send the guitar to an Aux, via a Bus, put a gate and then a bunch of distortion and fuzz on the track after the gate. Then I played with the gate settings so that it was on the edge of closing and opening. So the end result was like a lo-fi distortion that was cutting in and out rapidly. Kinda neat.
One thing I would suggest is if you use Aux tracks via a Bus, make sure you mute the Bus track in the environment, or else you will get the signal from the Bus and the Aux track.
Have fun and be super creative!!!

  • Why use Oracle 8.1.5 for Linux?

    Dear,
    If it is really pain in the ass to install Oracle on Linux, why
    use it? I have spent more than 4 full days (more than what I
    excepted) to try to install Oracle on a Linux box.
    I guess I will go for mySQL since I can just install the RPM
    package and do not have to worry those critical issues.
    Just a note for Oracle, please design a better Installer next
    time which is going to work! Thank you.
    Best Regards,

    I have some sympathy for your plight. I have 8.0.5 installed on
    RedHat Linux. Apart from patching the Pro*C configuration file,
    everything is fine.
    It does seem 8.1.5 is more problematic. If you're purely
    evaluating Oracle, maybe you should consider 8.0.5 until 8i
    stabilises unless you really are gagging for some 8i feature.

  • Why Using Top Link is best in DB Adapter?

    Hi All,
    Can any one suggest , Why Using Top Link (Build-in Insert, Select etc. operation) is best in DB Adapter over using custom query?
    Thanks

    Hi Vikky,
    for insert/select it depends on what kind of user you are. TopLink lets you browse and click on a tables and have everything generated for you. If you are more a DBA or show me the SQL type then you can just type SQL directly.
    Some advantages of TopLink would be:
    -The range of SQL generated by TopLink is limited, but if you hard code complex SQL into your service you need to maintain it.
    -TopLink can generate at runtime the correct SQL for a given database, making switching from say DB2 to Oracle easy.
    -The merge operation will compare the input XML to the columns on the database and update only what has changed. It can also do a sparse merge. If only 4 columns in the XML were set, only those 4 columns in the database will be updated.
    -For inbound polling the strategy used (LogicalDelete, Sequencing Table, etc) is a configuration property and then at runtime multiple SQL statements are generated. The SQL also takes advantage of advanced syntax like the Oracle-only FOR UPDATE SKIP LOCKED, writing it all yourself may be tedious and error prone.
    -The main benefit of TopLink is when you go beyond thinking about a single table. If you import multiple related tables at once, TopLink will generate the SQL to select from and maintain multiple tables, establish a commit order, and generate a hierarchical XSD. With custom SQL the matching XSD is always flat. I.e. if you just need to insert an emp you could get away with custom SQL. If you need to insert a dept and emps, I would use TopLink.
    -This is also when the intermediary abstraction of an object/table makes more sense, as you only need to import a complex relational schema once, then generate inserts, selects, etc.
    So I hope that helps. They are each equally viable and can do something that the other can't. Where you see an overlap I would go with personal preference.
    Thanks

  • Why use interlaced ?

    We shoot with DVCpro50 at 24p.
    A few questions.
    1. Is there anytime that there is an advantage, or a time when you have to use field dominance ?
    Interlaced footage looks like crap. Stills look horrible in an interlaced timeline - why ever use it ?
    It seems I can just switch the field dominance from "lower/even" to "none" and everything looks 10 times better on computer and NTSC monitor.
    2. Is there anytime that there is a disadvantage to removing the pulldown and editing in 24fps. It looks 10 times better without the screwd up "B/C & C/D" frames if you leave it in and edit at 29.97fps.
    3. is there any advantage or quality enhancement by removing the pulldown in "Shake" rather than letting FCP do it while capturing. And after removing, should your sequence timeline be set to 24fps or 23.98fps and why ?
    4. Have G5, OSX 10.4.8, AJA IO hooked up to NTSC monitor, and can't view 24fps timeline on external NTSC monitor - only frames when parked - is that because these monitors will only accept 29.97 field dominated footage ?

    Fist off - thanks for the help on part 4.
    I know how TV works and why NTSC was invented over a half century ago.
    Now that I can monitor on the external I will always edit in 24. I'm only the editor - they shoot with a SPX900 in 24p - if you don't remove the pulldown, frames 3 & 4 out of the 5 frame cycle combined with the interlacing gives really bad results. So out of curiosity I switched the sequence dominance setting from "lower/even" to "none" - at this point is ii still treated as interlaced or if it is set to "none" is it now progressive, like when you are editing in 24 and the field dominance window is greyed out. I would think that this would look jittery on a TV because the field order isn't right - but it doesn't - I can make DVD, VHS(not sure why), and monitor and the only difference is that the stills look incredibly better - there's no banding and stair stepping on the shoulders- on either the computer monitor or the NTSC monitor. And with it set to "lower/even" the bigger the computer or TV screen the worse it looks - but with it set to "none" the stills just get softer as you view them on bigger screens as if the right amount of gaussian blur was being added automatically - Isn't that wht you want ?
    So that was why I ask "why use interlace" if you have a choice?
    I'm not trying to be cool - these are ligitimate questions. I consider this doing my homework - isn't that what forums are for - I help people with answers all of the time.
    As for part 3 - Does "standard pulldown" refer to going back & forth between 24fps (film) and 29.97 (video) and "advanced pulldown" from 23.98 to 29.97 ?
    Are all of these modern video cameras actually shooting at 23.98 ?

    Hi Frank,
    In the example, the "{cache-name}" is supposed to be replaced by the database's table or view name that will be queried for the data to be cached. It's purpose is demonstrate how to pass parameters to the class constructor.

  • Why use layer masks and adjustment layers?

    I've been using PSE and CS successfully for years.
    One thing I have never understood is: why use layer masks and adjustment layers, instead of simply creating a copy of the subject layer (the one I want to make changes to) and experimenting with that?  It's quick (Ctrl-J), I can do it as many times as I want, I'm not affecting my Background layer.  If I like the changes, I can keep them.  I can switch the copy on and off to compare with the Background layer.  I can do any type of blend or combination I desire.  I can insert Gradient layer(s), select any part of the copy and (Ctrl-J) create a new layer containing only the selected part.  I can adjust size, rotate, do anything.
    It almost seems that "layer mask" and "adjustment layer" are mainly another layer of terminology; can anyone explain (preferably in 50 words or less) how they are intrinsically different from or superior to working with copies of the Background layer?  What can be done with them that can't be done simply using copies of the Background layer?

    Here's a very basic example of the advantage of using a layer mask.
    I have this picture of a sunflower and I want to convert the background to black & white, leaving just the flower in color.  I duplicated the Background layer, converted it to B&W and proceeded to use the Eraser to uncover the flower color. But I made a mistake and erased outside the flower.  There is no way to correct this other than deleting the layer and starting again.
    Now let's use a layer mask on the B&W layer. Set the Foreground/Background colors to the defaults black/white. Using the Brush tool paint on the mask with black to reveal the color.  Here I painted too far, revealing a green leaf in the background.  No need to start over.  Simply switch to white and paint the excess to convert back to the B&W.
    Tip: while painting you can type "X" to toggle between black and white.
    You could also select the flower using the various selection tools and then fill the selection with black. If it turns out the selection was not 100% accurate you can then fine-tune the result by painting on the mask with black or white as necessary.

  • Max number of Messages using Channel API?

    We have a 2-port CAN card (series 2) runing at 500kB. When we use channel API to setup 9 messages (about 20 signal-channels) at 100Hz update rate in a write task - the data is constant, set to repeat output last sample (therefore butffer size is not the problem).
    Task Init-start gives error of too many channels too high speed. when we set only 8 messages at 100Hz or 9 messages at 90Hz, it works fine.
    If we calculate based on 500kB and 8-byte messages (give enough overhead), CAN bus shall be able to transact at least 40 full-length (8-byte) messages at 100Hz.
    there are two Rx messages at 50Hz on the bus. (totally only these 10 or 11 messages are on the bus).
    so what is the problem, simple because the CAN channel API is not good enough? 

    The NI-CAN driver I used was 2.3.1f1(?), then updated to 2.4.0f0. the results are the same. the erroe code is: -1074388831.
    Dirk is right. I did some tests and find the max speed it can spit to the bus is 666Hz (frames/s). this is true for both channel API - sampled ouput and for frame API - CAN objects.
    this will not meet the requirement of my (and many) application. I want use the NI CAN card to simulate several controllers in a vihicle to talk to one controller to be test. there are usally more than ten messages, many of them at 10ms update rate.
    when using frame API network object, timestamped, the max throughput seen is 830Hz.  when use "immedaite", the max throughput is ~3.15kHz (76% bus load). this rate probably meets most application,
    what's Interesting is, when use channel API, signle write (sample rate 0) in a loop, use the loop to control the rate, it is able to reach same ~3.2kHz rate, although the timing is not very accuate (but the channle API is not well timed either at higher rate: 6 messages sample rate at 100Hz, ouput recent: varying from 96 to 104Hz).
    the driver needs some improvement.

  • Why using workarea for internal table is better in performance

    Please tell me
    why using workarea for internal table is better in performance

    Hi Vineet ,
      Why would we choose to use an internal table without a header line when it is easier to code one  with a header line?
    it has following reason.
    1)Separate Internal Table Work Area:
         The work area (staging area) defined for the internal table   is not limited to use with just one internal table.
    take ex-
    Suppose you want two internal tables for EMPLOYEE – one to contain all records and one to contain only those records where country = ‘USA’.  You could create both of these internal tables without header lines and use only one work area to load data into both of them. You would append all records from the work area into the first internal table.  You would conditionally append the ‘USA’ records from the same work area into the second internal table.
    2)  Performance Issues:  Using an internal table without a header line is more efficient than one  with a header line
    3) Nested Internal Tables:  If you want to include an internal table within a structure or another   internal table, you must use one without a header line.
    If this one is helpful ,then rewards me
    Regards

  • Why use go:title etc...

    I've just seen this in the meta data of a website:
    <meta property="og:title" content="foobar...
    There's loads of them… go:description… go:audio… go:keywords… and so on
    Apparently it's to do with open graph and Facebook which I don't fully understand, but why use it and what are the advantages? I've googled it, but I'm finding little ore than what I already mentioned. Just wondering if anybody here knew a little more detail than the info I've found.
    Thanks.
    Mat

    From this page - Facebook Content Sharing Best Practices
    I read:
    Use proper Open Graph tags
    Open Graph tags are included in your page’s HTML and allow the Facebook Crawler to generate previews when your content is shared on Facebook.
    We give examples below, but the basic Open Graph tags you should implement are:
    og:title – The title of your article, excluding any branding.
    og:site_name - The name of your website. Not the URL, but the name. (i.e. "IMDb" not "imdb.com".)
    og:url – This URL serves as the unique identifier for your post. It should match your canonical URL used for SEO, and it should not include any session variables, user identifying parameters, or counters. If you use this improperly, likes and shares will not be aggregated for this URL and will be spread across all of the variations of the URL. 
    og:description – A detailed description of the piece of content, usually between 2 and 4 sentences. This tag is technically optional, but can improve the rate at which links are read and shared.
    etc.

    My " NewBie" Definition of Thread Safe :Is of no interest. It already has a definition and that isn't it.I wanted to make clear what my definition is.
    The [JLS DEF FOR COLLECTION|http://java.sun.com/j2se/1.4.2/docs/api/java/util/Collections.html] says:
    That is the Javadoc for Collections actually, nothing to do with the JLS or Collection.They are authoritative links for Java Language and the discussion in hand, not Fantasies of Lucy Aunty.
    So,how do we draw any inference(s) here?Yes, that you have selectively quoted the Javadoc, which goes on to talk about how you have to use it when iterating.Still not answering my question,Sir.
    ejp,you seem to have knowledge but you don't have the attitude to forward the same to others or bear what others say,even when initiative has been taken by others to put forward a problem.

  • Why use customized / particular exceptions instead java.lang.Exception

    Hi,
    Do any of you guys know where can I find a theorical statement / explanation about why use particular / customized exceptions instead java.lang.Exception? I am aware that it consumes more resources and becomes a heavier object, as well as the clearness when coding and all that stuff; however, my boss wants to see a tech document where all this is clearly stated. Any resource over there?
    Regards

    It is better to throw specific--or at least module- or
    package-specific--excpetions, rather than Exception,
    because then the caller knows what to expect. However,
    if you declare "throws Exception", the caller can
    still catch IOException, SQLException, etc.,
    separately. He'll just have to be a really good
    guesser as to which ones he should catch.True.
    Also, there's no point in declaring "throws
    NullPointerException." Any method can throw it without
    declaring it. If you generate your own NPE (or other
    unchecked exception) inside the method, then you
    should document it in the javadoc comments, but you
    don't need to put it in the throws clause. It doesn't
    do any harm, but it's redundant and cluttersome.It was an example and I wasn't feeling too creative....excuse me. ;-) But yeah, I've never thrown NPE ever.
    I'm assuming overhead caused by extending classes.At
    the worst, it would be miniscule, or so I wouldthink.
    What overhead is created by extending classes?Hmm, I was under the impression that a class the extended another class, inherited all of the other classes data (variables, etc.). Hence, you get something like this:
    SuperClass1 + SubClass1 + SubClassOfSubcCass1 = Memory usuage for SubClassOfSubClass1.
    Since adding postivie number will always end up increasing data, SubClassOfSubClass1 will use more dtat than SuperClass1.
    Am I wrong?
