Is Color Luma Curves the same as 'HueCureves' node with luminance selected?

In Apple Color there are the "Luma Curves". Is this the exact same thing as the 'HueCureves' node with the luminance selected?
here is what I am talking about in Apple Color
http://www.vimeo.com/3418777

No, the Curves Controls in Color consists of lookup tables.
The Luma Curve in Color corresponds to using Shake's LookupHLS node
with lExpr (luminance) selected.
The other three curves in Color correspond to using the Lookup node
with rExpr, gExpr, and bExpr selected.
Lookup tables map input channel values to output channel values.
(Color manual page 190). Shake's HueCurves node maps input hue
to the amount that hue is boosted or cut.
If you have experience in audio, it might make sense to think of
a lookup table as a dynamics processor (compressor or expander),
whereas a hue curve is like a filter (graphic equalizer).

How do I copy a document from pages into email (not pdf) and have color and format the same as the document created in pages?

How do I copy an entire document from pages into email (not pdf) and have color and format the same as the document created in pages?

Pages ’09 v4.3 and Pages v5.2.2 are entirely different document architectures. Consequently, copying and pasting a table from Pages ’09 circumvents the customary translation process that would occur if you opened that Pages ’09 document in Pages v5.
Make a backup copy of the Pages ’09 document that has the table in it, and then open this document in Pages v5.2.2. The table is translated into Pages v5 document format and displayed correctly. You can even select this Pages v5.2.2 table, and then copy/paste it into another Pages v5.2.2 document with accurate results.

How can I copy an audio effect from a clip and paste it to another clip in the same timiline...With FCPro 7 it was all so fast........

The advantage goes to FCP7 if you allow that it can copy and paste filters, audio and video, transformations, and other attributes separately.
You can do that in FCPX too, as all the things you cited are listed separately in the inspector.
Here's a little gotcha. Let's say you've color corrected a few clips and you've applied an effect to one and want to paste it the other clips. You switch off color correction and copy the clip. You select the other clips and paste effects. What do you think happens? The effect is applied, but the color correction is applied as well, only it's switched off as it was in the first clip, so all the color correction on the other clips is lost. Fun, eh?
I'll try to replicate your gotcha - but no, that doesn't sound like fun at all!

How to sync 2 different Mac users using the same Apple ID and with out mixing each other info?

How to sync 2 different Mac users using the same Apple ID and with out mixing each other info?
We are two people using three difrent Macs, 1 Iphone and 1 Ipad with separate USERS on each Mac but sharing the same Apple ID: xxxxxx
I set up the first user to iCloud and it was OK but when I set up the second user to use iCoud the first users's info gets mixed with the second user's info?
Do we have to set up a diffrent Apple ID for each other?
Sometime ago I added my friends E mail (yyyyy) to the main Apple ID (xxxx) as for using his E mail account (to separate our e mail accounts, and it's working ok) but now when I try to create a new apple ID whith the same friend's e mail (yyyyyy) it says that his mail (yyyyy) is already an apple ID when the Apple ID is really my E mail (xxxxx)... any clue?
Thanks

I believe because you migrated from a Nokia to an iPhone you need to register the Bn phone number with your Apple ID so it can be used for iMessage. The Pn number seems to be the only one registered
Go here > https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/
Manage your Apple ID and see if that does the trick
Hope that helps

There is no space to store video on my computer. I am am looking at getting 1 terabyte on the cloud in hope i can edit video off of the cloud the same way I can with a hard drive. Is this possible?

Buy another hard drive. They're cheap these days.
In fact, buy a couple of 'em. I recommend a minimum of five internal hard drives.

Hi! I have a library of around 1000 songs on my iTunes, I recently synced my phone and all was lost, my partner has the same songs on hers with a different sign in, but not backed up anywhere, any suggestion on how I can store her tunes in my account ???

Hi! I have a library of around 1000 songs on my iTunes, I recently synced my phone and all was lost, my partner has the same songs on hers with a different sign in, but not backed up anywhere, any suggestion on how I can store her tunes in my account ??? Then sync them to mine? When I sign her phone into her account I get a message warning that if I sync the dogs on her phone will be replaced by the ones in the library! But as there are no songs there I'm reluctant to continue!!! Please help this non techi guy.!!!!!

Hello Solid Buck,
Thank you so much for providing the details about the duplicate song issue you are experiencing. It sounds like you would like to remove the duplicate songs that will not play on your iPhone, but when you connect it to iTunes, iTunes only shows you one copy of the song on your iPhone.
In this situation, I recommend deleting the individual songs that do not play directly from your iPhone. I found the steps to do this on page 61 of the iPhone User Guide (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf):
Delete a song from iPhone: In Songs, swipe the song, then tap Delete.
Thank you for using Apple Support Communities.
Best,

Starting in 2015 I get the following error when I try to import my photos. "The following files were not imported because they could not be read" -DSC8416.NEF I've been importing the same type of photos with no errors then 2015 came along and now I can

Starting in 2015 I get the following error when I try to import my photos. "The following files were not imported because they could not be read" -DSC8416.NEF I've been importing the same type of photos with no errors then 2015 came along and now I can no longer import.

The error message is misleading, the problem is that you need WRITE privileges added to the destination directory tree.
Assuming you are using the "date" structure that LR defaults to, find the directory that contains the 2014 folder (the one that works) and add WRITE rights to the parent of "2014".
While you are there, if you want, add "2015" folder to beside "2014" and add READ and WRITE rights to that new directory.

My wife is having the same problems as a reciever. She works in a school as a teaching assistant and her teacher sends messages that are mixed with previous texts from ages ago.
Can anyone shed some light on this problem or is it only her and this poster?

Different Migo posted on the same delivery note number with the same vendor

Hi Experts,
We are facing a peculiar problem while saving migo in the sytem. The system is allowing to post more than one migo with the same delvery note number with the same vendor code in the same financial year. Ideally shystem should give some informative / error messgage during saving one migo. In our company, we capture party invoice number in the delivery note option. Our problem is more promintent if the vendor is non excisable.
How to check this problem.
Regards
GR

Hi,
In Standard SAP, no check is available on "Delivery Note" field for duplicacy. This is only available for "Reference" field in MIRO.
If you want to have a check on "Delivery Note" field in MIGO then go for some ABAP Development using BAdi or Enhancement Spot "MB_MIGO_BADI".

Yes. Two iDevices can share the same iTunes Library as long as both are configured to use the same Apple ID.

Hi, I've been using the 3D function in PS, upgraded to CC2104 and it was disabled (need more VRAM). I then reinstalled CS6 and was able to use it for a day and now, today, I am getting the same message I got with PS CC2014 saying my VRAM is too low again.

Photoshop requires 512 Meg of VRAM or more to use the 3D features - that's been the same for version 14 (CC) and now 15 (CC 2014). Check Help->System Info to see how much your card says it has.
