Any tips on how to photograph the Northern Lights?

Ok, I'm planning a cruise to see the Northern Lights so apart from being there at the right time............
What would you recommended for camera settings and setup to get the best shots of the Northern Lights?

About 2/3 down the page, he gives you the camera settings.
Manually prefocus at infinity. Disable autofocus, as it is unlikely that your camera will automatically lock onto an aurora – it is more likely to focus on your breath. Consider taping your focusing ring so it does not inadvertently shift in the dark away from infinity.
Select the largest lens aperture available (preferably f 2.8 or below). With a moving aurora, stopping down in an effort to improve sharpness is often counterproductive.
Choose the highest ISO with which your camera will provide reasonably good quality output.
Manually set your exposure time and keep it as short as possible, ideally well under 30 seconds.

I have recently put in another hard drive into my system to hold my iTunes any tips on how to transfer the system easier?

What is the easiest way tostill have my iStore and iTunes accounts and switch from my C: drive to my E: drive which is my new hard drive?

I have tried contacting Apple Support and they aren't supposed to give out info for XP. My warranty is with Best Buy and they said that they would reinstall iTunes into my E: drive for only $149.00.It cost me $200.00 to have the second hard drive installed by the people that made my computer. I just wanted more space to start my art business which will require the first hard drive's space. Plus when I'm working or playing on my computer I HAVE, NEED, itis REQUIRED that my music be playing. Needless to say right now I'm going nuts

Morning Lupoipia,
Thanks for using Apple Support Communities.
If you can't be heard by someone who is calling, take a look at this article:

Tried unsuccessfully to restore my MBP, running the Mac OSX Lion, to factory settings. I keep getting the "can't download additional components for the Mac OSX Lion" error when reinstalling the OSX Lion. Any tips on how to resolve this problem?

Hello! Tried unsuccessfully to restore my MBP, running the Mac OSX Lion, to factory settings. I keep getting the "can't download additional components for the Mac OSX Lion" error when reinstalling the OSX Lion. Any tips on how to resolve this problem?

Hi
Given that your answer to 1. is 'pre-installed' and 3. is 'No', I think the only thing to do is to take it to an Apple store (ideally the one you bought it from) and have them reinstall it for you.
The intended solution in cases like yours is that you should be able to reboot and install even a wiped disk by using Apple's servers over the internet (you do this by restarting with 'command-r' and choosing 'reinstall Lion'). However if this isn't working for you then you need to get the store to do it. Don't let them fob you off with 'go home and try again'. Have them do it in the shop (you're still covered by Applecare warranty so it should cost you nothing save the inconvenience of the trip and possibly leaving the machine there while they fix it).
A reinstall should leave all your own personal data and programs in place.
Note for future: when you get it fixed, first thing to do is buy a cheap external drive and start keeping a backup (either Time Machine or clone with Carbon Copy Cloner).

Go back to that article, ignore the instructions for updating it wirelessly, scroll down, and follow those for updating it from iTunes on a computer.

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?
I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
This was my first Mac since an old Apple II GS. After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc. Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
That said, any tips?
Thanks
It does have a crack on the left of the screen case about 3/4'' up from the bottom. I've posted that as another question.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little.

Does any body knows how to detect the resolution of an inserted image in word?

I'm not sure I understand your reply but when you insert images into Word that are larger than will fit on the page, they are automatically compressed. If you right click and select Size and Position you can restore it to 100% but you will not see all the image.

I have lost over 20,000 photos in my iPhoto'08 program (v 7.1.5). Any tips on how to relocate them?

I have lost thousands of photos in my iPhoto'08 program (v 7.1.5). I don't think they are lost from my iMac as the storage amount hasn't decreased but the last several years of picks (over 20,000) are not showing up. Any tips on how to relocate them?

Hi LarryHN-thanks for your quick reply!!
Nothing recently changed that Ican think of! I went on vacation and when I returned, I uploaded my new photos. That's when I discovered that the new photos were in the library but very few other photos were.
When you say to back up the iPhoto library, is this something different that backing up the entire iMac to an external hard drive?

Does anyone have any tips on how to maximize battery life of MacBooks ?

I have just bought the new Macbook 15'' after my older macbook (2009 version) had gone through some issues with its battery. The battery life of my old mac became very short, maybe due to overcharging etc. Therefore I want to make sure I dont make any mistakes this time around and make good use of my battery so that it doesnt get damaged too fast. Does anyone have any tips on how to do this? Or perhaps any MUST NOTs (things that would be harmful to the battery), eg. overcharging?

Welcome to Apple Support Communities
Macs do not have overcharging. The battery is stopped being charged when it is full, so do not worry about that.
The most basic tip is to make regular battery cycles and do not disconnect the MacBook Pro from the charger until the battery is fully charged. Then, if you want, you can use your MacBook plugged in all the time, but remember to make a cycle at least once a month to keep the battery life. Also, do not let your MacBook turn off because its battery ran out of energy.

Usually it's because you are not making internet connection via wifi.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Any tips on how to improve battery life on new macbook pro?

Any tips on how to improve battery life on new macbook pro?

It all depends on how much you plan to run on battery power. If you don't use it often, set yourself a reminder to let it run unplugged about every couple of weeks to aboout a 40% charge and then plug it up and let it charge back to 100%. If you'r'e a frequent battery user (like me) don't let your MBP discharge to the point where you're running on reserve power - down to about 30 minutes remaining and then charge it back in.
I have over 130 cycles on my computer and I've just had it since March. Even though my battery health was 102.2% when I got my MBP, it's still at 98.8% health and I'm still getting 7+ hours out of my battery. To get the longest use when under battery, keep your activities to low-CPU intensive apps (browser, email client, word processor, etc.) - Internet surfing alone, and not watching a lot of online videos, will give you mor ebang for the buck. You can also check your battery health in 'real time' by using "Battery Health" - free from the App Store and you can make sure that you're running on integrated graphics, which uses less power, by downloading Cody Krieger's exceptional gfxCardStatus.
Keep your screen brightness down to about four ticks and your keyboard backlighting to one tick - should work fine.
Good battery health to you,
Clinton

Does any one know , how to delete the others in itunes. it takes lot of space

does any one know , how to delete the others in itunes. it takes lot of space, i wanna delete that... Actually what it contains

Those are the data of the installed apps. Don't listen if someone says that it's an iOS, because it is not. On your iPhone, go to general > usage. It will show you all the programs installed on your iPhone. If you click any of them you will see how much of "others" it has (documents and data)
There's no way to delete it if you want to still have those apps. You can reinstal those which has the most "others" but after some time of usage, it will raise again.

I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.
