Question about "Native ISO" and Color Grading in PP

I have a question about "Native ISO" in the real world and how it relates to color grading. I was shooting 35mm film before all these digital cameras became flat-out amazing practically overnight. Then the goal was always to shoot with the lowest ISO possible to achieve the least amount of grain (unless you were making an artistic decision to get that look). If I was shooting outside plus had a nice lighting package I'd shoot 5201/50 ASA (Daylight) and 5212/100 ASA (Tungsten) 99 times out of 100.
I've recently been shooting a lot with the Blackmagic 4K and have read that its "Native ISO" is 400. Because of my film background this seems counter-intuitive. Yesterday I was shooting for a client and had the camera at an f16 with a 200 ISO. Because of what I'd read, I was tempted stop down to an f22 and change my ISO to 400... but the "little film voice in my head" just wouldn't let me do it. It kept telling me "Higher ISO means more noise... stay at 200 and you will get a cleaner image".
So how does it work with "Native ISO"? Should I really shoot at a 400 ISO every chance I get in order to capture the best image for how the camera is calibrated? Will it really give me more latitude when color grading? Or would I still get a cleaner image staying at ISO 200? I've Googled around quite, but haven't found any articles that answer specifically this question. Would love to hear from someone who knows a bit more on the subject or has a link that could point me in the right direction.
Thanks much.

Hey, shooter ... yea, interesting discussion and always nice to learn. Great pic, too!
jamesp2 ...
Great answer. I've followed quite a bit of the discussion about the BM cams as well, one does feel a need to check out the possibilities for that next beastie one will need to acquire. But ... which one?
I've always been a bit of a hard-case about testing testing testing. For instance, what happens with dome down or use of a flat diffuser vs. dome in the up position in metering? Back in the film days, we had our own lab and did our own printing as well as the um ... difficult images ... from other studios. I needed to know how to get exactly the same diffuse highlight no matter whether it was a "standard" light 3:1 studio shot, or a near-profile with no fill that needs dark shadows. I tested & burned through boxes of medium-format polaroid & 120 film and a lot of color paper. Finding? To get the same print time no matter the contrast or lighting style, needed to be metered either with the flat disc (Minolta) or dome-down (Sekonic) and held at the highlight-location pointed at the main light source. I could meter and nail the exposure every time. Ahh no, insist so many ... one must have the dome on/up and pointed at the camera! Right. Do that, change the contrast, and see what happens to your diffuse forehead highlight on a densitometer ... and see how your printing exposure times change. Oh, and you've just moved your center-of-exposure up or down on the film's H&D curve, which will also change the way the shadows & highlights print. In truth, though it was subtle, we had realistically no matter latitude for a best-case image with pro neg film as one had with chromes. You could probably get away with being "off" easier, but it still wasn't dead-on.
So wading into video ... oi vey, you may have noticed the things claimed here there & everywhere ... this setting is God's Gift to Humanity but no, it's total crap ... this sensor is totally flawed but someone else is certain it's the finest piece out there. Yes, opinions will be all over ... but ... in film, it was the densitometer. In video, it's the scopes. Truth. And getting to that can be a right pain. I've seen quite a few contradictory comments about using the BM cams in film mode and also at ISO 200. Yours above gives the most ... comforting? ... explanation (for me) because of your reference to your scopes & the waveform patterns. Thank you.
Love to learn ...

Question about clear page and reset pagination

Hi,
I have a question about clear pages and the reset pagination in an URL. What is the reason why a clear page doesn't also trigger a reset pagination on the pages which are cleared?
I can't really imagine a business case where it makes sense to clear all data of page items on a page and don't reset the pagination of reports on that page which probably use a page item in there where clause...
The drawback of this behavior is that a developer always has to set the reset pagination checkbox when he clears the target page and the even bigger drawback is that if you specify other pages to clear, you can't reset pagination for them, because reset pagination only works for the target page.
Thanks for your input.

The question about portlet customization and synchronization

I have a question about portlet customization and synchronization.
When I call
NameValuePersonalizationObject data = (NameValuePersonalizationObject) PortletRendererUtil.getEditData(portletRenderRequest);
portletRenderRequest.setPortletTitle(str);
portletRenderRequest.putString(aKey, aValue);
PortletRendererUtil.submitEditData(portletRenderRequest, data);
Should I make any synchronization myself (use "synchronized" blocks or something else) or this procedure is made thread-safe on the level of the Portal API?

HI Dimitry,
I dont think you have to synchronize the block. i guess the code is synchronized internally.

Advice for logical workflow for color correcting and color grading

I am an experienced user of PPRO CS5. I am a novice with color correcting and color grading. I am also just barely competant in AE CS5. It has been suggested that I use AE for color correcting my footage. Can you advise me as to the most logical workflow for doing this in coordination with PPRO CS5? Are there some tutorials that you recommend? I subscribe to Lynda.com and I think that they have some great tutorials, I am unsure as to where to begin looking and what to search for.
Thanks so much,
Lisa

You can do it that way, sure. But you don't have to. You can accomplish quite a lot without leaving PPro. This has two major advantages. First, if you aren't using AE for anything else, it gets you out of using AE at all, so gets you out of climbing another set of learning curves.
Second, even if you are using AE for other things (I use AE to make motion lower thirds, for example), doing the work in PPro can improve exporting speeds. This is because AE gets restricted to a single processor core in some workflows as discussed in this thread and others (search around if you're interested). This can make exporting take 3x as long or longer, depending on how much footage has to be processed by AE.
So, how to do color correction without leaving PPro? Use either a luma corrector or luma curve effect to set black and white points, and contrast (use a waveform monitor to help). Then use a three way color corrector effect to get rid of any residual color casts (use the vectorscope to help, and the RGB parade, etc.).
If you find you have specific colors that need to be fixed, you can apply another three way color correction effect and use it to make that secondary color correction (for example I find the blue dyes used in many labels tend to fluoresce under fluorescent lighting, and has to be desaturated with a secondary color correction or it "blooms" on an HDTV -- IOW, it has to be made "broadcast safe").
If you want tutorials for using these tools, the ones on Creative Cow by Andrew Devis are quite good, and free. The ones on color correction with PPro cs6 start at tutorial number 47. There's a bunch of them. All good.
Finally, get a copy of Van Hurkman's Color Correction Handbook. May be the best technical book I've ever read, and it'll certainly point you in the right direction for doing color correction work regardless of which tools you use to do it.

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

A few questions about the ka790gx and dka790gx

i have a few questions about the ka790gx and dka790gx , how much better is the dka790gx compaired to the ka790gx ? . how much difference does the ACC function make to overclocking etc , i plan on getting a phenom II 940BE or 720BE . i already have the ka790gx so would it be worth building another system using the dka790gx mobo , or should i keep what i already have and just change the cpu ?

It's largely irrelevant what other boards had VRM issues other than the KA790GX - the fact is it died at stock settings. Since there is little cost difference between the more robust DKA790GX (or Platinum if you really need 1394) why bother with the proven weakling? There are other examples around of the KA not having a robust power section. There's no way I would use even a 95W TDP CPU in the KA and absolutely not O/C.....!
As for the credentials of Custom PC, I have generally found their reviews accurate and balanced, and echo my own findings where applicable. If a little too infrequent.
The fact that the KA has such a huge VRM heatsink leads me to my other comments on the Forum, particularly regarding the "fudge" aspect:
"""Henry is spot on - the notion that adding a heatsink to the top of the D2PAK or whatever MOSFETS is effective is virtually worthless. The device's die thermal junction is the tab on the device back - which is always against the PCB pad. The majority of heat is therefore dissipated in to the board, and the fact that the epoxy plastic encapsulation gets hot is simply due to the inability of the heat to be conducted away from the device die via the tab. Not sure when Epoxy become an effective conductor of heat.... Good practice is to increase the size of the PCB pad (or "land" in American) such that the enlarged PCB copper area acts as an adequate heatsink. This is still not as effective as clamping a power device tab to an actual piece of ali or copper, but since the devices used are SMD devices, this is not possible. However, the surface area required to provide sufficient PCB copper area to act as a heatsink for several devices isn't available in the current motherboard layouts. Where industrial SBC designs differ in this respect is to place the VRM MOSFETs on the back of the PCB on very enlarged PCB pads - where real estate for components is not an issue.
Gigabyte's UD3 2oz copper mainboards sound like a good idea, on the face of it. However, without knowing how they have connected the device tabs to where and what remains a mystery. I suspect it is more hype than solution, although there will be some positive effect. From an electrical perspective, having lower resistance connecting whatever to whatever (probably just a 0V plane) is no bad thing.
The way the likes of ASUS sort of get round the problem is to increase the sheer number of MOSFET devices and effectively spread the heat dissipation over a larger physical area. This works to a degree, there is the same amount of heat being dissipated, but over several more square inches. The other advantage of this is that each leg of the VRM circuit passes less current and therefore localised heat is reduced. Remember that as well as absolute peak operating temperature causing reduced component life, thermal cycling stresses the mechanical aspects of components (die wire bonds for example) as well as the solder joints on the board. Keeping components at a relatively constant temperature, even if this is high (but within operating temperature limits), is a means of promoting longevity.
For myself, the first thing I do with a seperate VRM heatsink is take it off and use a quiet fan to blow air on to the VRM area of the PCB - this is where the heat is. This has the added benefit of actively cooling the inductors and capacitors too....
Cooling the epoxy component body is a fudge. If the epoxy (and thus any heatsink plonked on top of it) is running at 60C, the component die is way above that.....
It's better than nothing, but only just."""

HD TV or LCD monitor with HDMI,DVI supported to preview and color grading

Finally I got my canon HFS100 and Intensity Pro now what type of the monitor should I get to preview and color grading video via intensity pro between HD TV or LCD monitor with HDMI,DVI supported and how to calibrate monitor via intensity pro.
Please help.

The main downside is that an HDTV is designed to be used at TV viewing distance. So it would work fine for presentations, where the audience is sitting more than 5 feet away. But at typical computer screen distance of 2-3 feet, it is the same 1920x1080 pixels spread out over a 32-inch screen. Oh, actually, that HDTV you mentioned is only "720p", which is only 1280x720. That may not look all that good at TV distance either, if you are displaying images that are static (non-motion).
Your eyes will have to work harder to see the same screen real estate, because everything is bigger on the screen. Images and text will not look as sharp (more pixelated) because each pixel is larger. It won't be like using a 30-inch Cinema Display, which has 2560x1600 pixels. Each pixel on that 32-inch 720p HDTV is more than 4 times larger.
A 1080p HDTV would be somewhat better, because that is 1920x1080 resolution.

Question about dependent projects (and their libraries) in 11g-Oracle team?

Hello everyone,
I have a question about dependent projects. An example:
In JDeveloper 10.1.3.x if you had for instance 2 projects (in a workspace): project 1 has one project library (for instance a log4j library) and project 2 is a very simple webapplication which is dependent on project 1. Project 2 has one class which makes use of log4j.
This compiles fine, you can run project 2 in oc4j, and the libraries of project 1 (log4j) are added on the classpath and everything works fine. This is great for rapid testing as well as keeping management of libraries to a minimum (only one project where you would update a library e.g.)
However in 11g this approach seems not to work at all anymore now that weblogic is used, not even when 'export library' is checked in project 1. The library is simply never exported at all - with a noclassdeffound error as result. Is this approach still possible (without having to define multiple deployment profiles), or is this a bug?
Thanks!
Martijn

Hi Ron,
I've tried what you said, indeed in that .beabuild.txt when 'deploy by default' is checked it adds a line like: C:/JDeveloper/mywork/test2/lib/log4j-1.2.14.jar = test2-view-webapp/WEB-INF/lib/log4j-1.2.14.jar
Which looks fine, except that /web-inf/lib/ is empty. I presume its a sort of mapping to say: Load it like it in WEB-INF/lib? This line is not there when the deploy by default is not checked.
I modified the TestBean as follows (the method that references Log4j does it thru a Class.forName() now only):
public String getHelloWorld() {
try {
Class clazz = Class.forName("org.apache.log4j.Logger");
System.out.println(clazz.getName());
catch(Exception e) {
e.printStackTrace();
return "Hello World";
In both cases with or without line, it throws:
java.lang.ClassNotFoundException: org.apache.log4j.Logger

Secondly I added weblogic.xml with your suggested code, in the exploded war this results in a weblogic.xml which looks like:

General question about iTunes Match and multiple libraries

Hello to everyone,
I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
Thanks a lot.

Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

Question about Id3-tags and song managem

Hello, I am getting ready to buy a Zen Touch 20GB in a couple of weeks and I have a few questions about the management software.
(Correct me if I am wrong about something)
) Are songs organized into groups by Genre instead of just folders like on the Ipod?
2) Are Id3-tags used instead of filename for identification?
3) What parts of the tag are needed besides title and artist?
4) Which version of tags does the Zen Touch recognize: Version or Version 2?
5) If I edit my tags using an external program such as Id3-TagIT, will the tags carry over to the Creative software and to the player?
Thanks a lot for your help. I want to make sure I have my music collection in order before I get my Zen Touch.

euph_jay wrote:Ok, so lets say I have all my music in folders right now seperated into different categories on my hard dri've. Some folders denote the artist, some the album, and some a genre. Example: Folder: Chicago Contents: Chicago .mp3 files Folder: Techno Contents: various Techno artist's songs What is the best way of organizing my folder system, so that the transition will be easy to the player?
Folders are pretty much irrelevant. What the software will do is look at the *tags* in the files and then use these to build the player's library.
Will imbedded folders work on the player? (like Techno->Crystal Method->Cystal Method .mp3's)
Again the player has no concept of folders, although if you set Techno as a Genre tag you will be able to view via this in the Music Library.
Or, am I misunderstanding how music is stored into the mp3 player. Instead of storing music in a "folder like" system (like the Chicago folder or Techno folder), does it store all the songs individually on the device? Then you have to sort it by artist, album, or genre?
Using your example, in the Music Library you have essentially three categories: Album, Artist, and Genre. So under Album you would see "Vegas" (the Crystal Method's album), under Artist you would see "The Crystal Method", and under Genre you would see "Techno" (and then either the album or artist under this... I forget which it is offhand).
Make sense?

Few questions about apex + epg and cookie blocked by IE6

Hi,
I would like to ask a few questions about apex and epg.
I have already installed and configured apex 3.2 on oracle 10g (on my localhost - computer name 'chen_rong', ip address -192.168.88.175 ), and enable anonymous access xdb http server.
now,
1. I can access 'http://chen_rong' , 'http://localhost' , 'http://192.168.88.175' without input username / password for realm 'XDB' in IE6;
2. I can access 'http://localhost/apex/apex_admin' , 'http://192.168.88.175/apex/apex_admin' , and I can be redirected into apex administation page after input admin/<my apex admin password> for realm 'APEX' in IE6;
3. I can access 'http://chen_rong/apex/apex_admin' in IE6, but after input admin/password , I can not be redirected into administation page, because the cookie was blocked by IE6.
then, the first question is :
Q1: What is the difference among 'http://chen_rong' , 'http://localhost' , 'http://192.168.88.175' ? I have already include site 'chen_rong' into my trusted stes! why the cookie was blocked by IE6. I have already tried firefox and google browser, both of them were ok for 'chen_rong', no cookie blocked from site 'chen_rong'!
and,
1. I have tried to use the script in attachment to test http authentication and also want to catch the cookie by utl_http .
2. please review the script for me.
3. I did:
SQL> exec show_url('http://localhost/apex/apex_admin/','ADMIN','Passw0rd');

And as I described above, the apex site works fine for ip address , and localhost. but the cookie will be blocked by IE6, if I want to access the site by 'http://computername:port/apex/apex_admin'. This problem does not occured in firefox and google browser. Could someone give me answer?

A quick question about WebDynpro SLD and R/3 with concurrent users

Hello ,
I have a very quick question about Webdynpros and SLD connecting to an R/3 system, when you configure a webdynpro to connect to an R/3 system using SLD, you configure a user name and password from the R/3 for the SLD to use. What I would like to know is when I have concurrent users of my webdynpro, how can I know what one user did in R/3 and what another user did? Is there a way for the users of the web dynpro to use their R/3 credentials so SLD can access the R/3? Like dynamically configuring the SLD for each user?
- I would like to avoid leaving their their passwords open in the code ( configuring two variable to get the users username and password and use these variables as JCO username and password )
Thanks Ubergeeks,
Guy

Hi Guy
You will have to use Single Sign On to achieve this. In the destination you have defined to connect to R/3 , there is an option to 'useSSO' instead of userid and password. This will ensure that calls to R/3 will be with the userid that has logged into WAS. You wont need to pass any passwords because a login ticket is generated from WAS and passed on to R/3. The userid is derived from this ticket.
For this to happen you will have to maintain a trust relation ship between R/3 and your WAS ,there is detailed documentation of this in help files. Configuration is very straight forward and is easy to perform

Question about metadata filtering and document sets

Hello,
I have a question about the metadata filtering when using document sets.
When i use the metadata filter for example for "Installatie: P00001" it shows.
But i wan't to show only the document set and not all the documents. Is this possible OOTB?

Hi striker,
You can add the "Content Type" in Hierarchy Fields for your list, then click the "Document Set" to filter the document set type item, then you can input the "P00001" in Installatle key filter, click apply, then it should show only document set
items with field value P00001.

Question on scanned images and coloring in Photoshop

I have some sketches from my drawing class that I would like to scan and color in Photoshop. I scan the sketch
but I can't add color. I've tried 'lassoing' a portion of the drawing
but the paint bucket still won't add color.
What am I doing wrong? Please help.
thanks.

The Paint Bucket tool may be the wrong tool, or at least you may have its Threshold set to a low value, as it replaces pixels only of a similar color to the one you click on.
It may be more direct to just select the Brush tool and set up a large brush to paint solid color in the region you selected.
If you want to get into more advanced functionality, which will allow you to correct mistakes or continue to adjust your colorizing for example, perhaps you will want to create a new layer and paint on that layer. Without knowing your goals it's hard to advise further, but you might also want to learn more about Layer blending mode "Color" vs. "Normal".
