Is there an advantage in optical transmission with TTL that you lose with radio?
I have an ST-E3-RT and 4 600EX-RTs and that is all I use for lighting. I use both E-TTL and Manual. I always prefer to use my radio for E-TTL but was wondering, is there an advantage whatsoever for someone in my case to ever use optical when all I need is Radio transmission either in E-TTL or manual? Is there an advantage in optical transmission with E-TTL that you lose with radio? I read somewhere that may be the case where the optical communication between speedlights for determining exposure in TTL is more accurate with optical transmission than radio. It may be that the Nikon folks are pushing that thought but wanted to check. Thank you all.
Solved!

Thank you very much TCampbell. That's great information. So there's really no reason to use optical if I use 600s with an ST-E3-RT?
To answer the question you've been getting at all along - No, optical offers no advantage that can't be achieved with the proper RF system. Conversely, there are several advantages to RF that optical lack. It would be a handicap to use the optical system if you have 600s and a ST-E3-RT.
If you don't have that system yet, but are considering it, keep in mind there are alternate options that are cheaper and can even have features the Canon system doesn't - such as wireless second curtain sync.

Is there a way to create hyperlinks "automatically with Firefox, as you can with IE (with, for example, Ctrl + K, then go to the website, then back to the document, and it automatically populates the url)?
If you create the folders as a child within the main pictures folder, then they will show up in the app separately. I have many folders with pictures in.
You will need to move the photos manually - they will automatically go in the Camera folder.
Hope that helps.

I have received the alert that my version of Safari no longer supports Youtube viewing. I am running version 5.1.10 on OS 10.6.8. Is there an update or a newer Safari version that is compatible with my OS?
No, not without upgrading to a higher version of the Mac OS. However, the easiest thing to do is get another browser for use with sites that don't like older versions of Saari. I always have a secondary browser on any computer, Mac or PC. For our Macs, I install FireFiox alongside Safari when setting up a new computer.
As FireFox is updated sometimes weekly, YouTube should not have a problem with it.

Why not use Lightroom 4 instead?
I mean, assuming you can get it running fast enough, you'll usually get better results with PV2012 - right? And in the cases where you prefer PV2010 (if there are any), it's there too...

When downloading the new 10.7 update for itunes, an error message saying that there is an error writing to file, verify that you have access to this file comes up... what is this??
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards? -
Iphoto will not open I am asked to check with developer that iphoto works with this version of OS x. I have Mountain Lion OS X I have followed all the steps recomended by T Devlin in a previous discussionand reinstalle ILife but to no avail
To reinstall iPhoto you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the:
HD/Library/Receipts folder (10.5 and earlier)
or from the /var/db/receipts/ folder (10.6) .
or from the /private/var/db/receipts folder (10.7 or later)
Then install iPhoto from the source it came from originally. -

Why do they cost over 10 x what seems available for PC?
Is it not possible to flash the cards for mac?

this recently happened, never had the problem before. I've restored my midi keyboard to factory settings but the problem persists. I go into garage band and click on the piano preset, but when I play a note it plays multiple instruments. Say I hit the C note On my keyboard, it plays the C note, but along with it is a snare hit or a shaker. And this is for every note. It seems as though the keyboard has its own setting, but I've tried resetting it. Again it's never happens before, just recently is there a way to get rid of that background sound? It's very dufficu to make music with multiple instruments playing in one note!
If it happens again the make sure that you aren't suppressing website colors.
Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.

What does it mean when there is a red slash through an app that is listed with my apps?
When I go to my computer and to the App Store I have noticed there is a big red slash mark on some of my apps. What does this mean?
It usually means that you may have upgraded the version of OS X to a version with which these apps are incompatible.

Need help with select that month range with flexible first date
Hello everyone,
I am trying to create a selection of month range (will be in a WITH clause) for a report to display monthly data. But the first month start date can be any date. (Not necessarily the first date of the month)
Examples:
Report input parameters:
Start Date: 08/10/12
End Month: Dec 2012
I was trying to build a with select that will list
Month_Start, Month_End
08/10/12, 31/10/12
01/11/12, 30/11/12
01/12/12, 31/12/12
OR
Month_Start, Next_Month
08/10/12, 01/11/12
01/11/12, 01/12/12
01/12/12, 01/01/13
End month is optional, so if no value the select will list only
08/10/12, 01/11/12

where
rownum <= months_between(to_date(NVL(:P50_END_MONTH, :P50_START_DATE),'DD/MM/YYYY'), add_months(to_date(:P50_START_DATE,'DD/MM/YYYY'), -1))
and rownum > 1If I put comment – on line and rownum > 1, as
-- and rownum > 1The result I get is
START_DATE NEXT_MONTH
01/10/12 01/10/12
01/11/12 01/11/12
01/12/12 01/01/13
10/10/2012 01/11/12 But when I try to remove the duplicate period (of the first month) out by restrict rownum, it do not return any rows for the second select at all. The result I get is:
START_DATE NEXT_MONTH
10/10/2012 01/11/12 Can anyone advise what wrong with the select statement ?
Thanks a lot in advance,
AnnHi,
Here's one way:
WITH params AS
SELECT TO_DATE (:p50_start_date, 'DD/MM/YYYY') AS start_date
, TO_DATE (:p50_end_month, 'DD/MM/YYYY') AS end_date
FROM dual
SELECT GREATEST ( start_date
, ADD_MONTHS ( TRUNC (start_date, 'MONTH')
, LEVEL - 1
) AS month_start
, LEAST ( end_date
, ADD_MONTHS ( TRUNC (start_date, 'MONTH')
, LEVEL
) - 1
) AS month_end
FROM params
CONNECT BY LEVEL <= 1 + MONTHS_BETWEEN ( end_date
, TRUNC (start_date, 'MONTH')
;:p50_end_month doesn't have to be the last day of the month; any day will work.
If you want to generate a Counter Table containing the integers 1 througn x in SQL, you could say
SELECT ROWNUM AS n
FROM all_objects
WHERE ROWNUM <= x
;but, starting in Oracle 9.1, it's much faster to say
SELECT LEVEL AS n
FROM dual -- or any table containing exactly 1 row
CONNECT BY LEVEL <= x
;Also, x can be greater than the number of rows in all_objects. -
How to set the Email(i) address that you get with your iPhone 3G in Japan?
This isn't covered in the U.S. manual probably because the feature is slightly different in Japan.
Basically the issue is this - cell phones in Japan have their own "cell phone email address". I believe that's not the case in the U.S.
So when I got my iPhone 3G in Japan today from Softbank, the cell phone provider, I also got a new email address [email protected] The "i" stands for iPhone.
The question is what to do with it? Unlike other cell phone providers, this is not set up on the cell phone itself when you get it.
Thanks,
dougI figured it out.
With the iPhone you can set up multiple regular Internet email accounts directly in the Mail app, using either IMAP or POP3 and even have your existing accounts synched from your computer.
It turns out that the [email protected] email account you get with your iPhone is just another "Other" account that you set up in the mail settings. When you add your Softbank address and password it automatically sets up the server to be IMAP for checking mail and the correct SMTP server and it just appears as one more push account in your accounts list.
I'm not sure it is really useful for anything or not, but since a lot of people want to know "what is your cell phone address" I guess it is best to set it and have one rather than explain why you don't really need a separate cell phone address for your iPhone.
It's sort of interesting. And it is actually an improvement over traditional Japanese cell phone email I think. And you can see nice HTML mail to boot.
Anyway, I hope this helps anybody else who doesn't know what to do with their extra Softbank address that comes with their iPhone 3G.

Is there a driver for eh HP Scanjet 3970 that will work with lion?
The scanner worked fine under snow Leopard.
HP Scanjet 3970Gee. not sure I can remember all the steps! It was so much a trial and error process.
I ended up with these apps installed:
VueScan ( free version) , HP Device Manager Version 1.4.7 (1.4.7), and HP Scan Pro Version 7.4.6

I deleted all previous versions of the scanning software that came with my HP scanner 3970
Even though VueScan didn't solve the problems it may have something in it that helped.
