How To Safely Move Your iPhoto Library to Another Hard Drive (Video Tutorial)

iPhoto Library Folder and icon

Sometimes your scanned or digital camera's photo collection is just so massive it takes over your entire hard drive. Maybe even to the point where now it's completely full!

If you don't want to replace your current hard drive with a larger one, moving your photo collection to an emptier secondary hard drive is always another option.

A Real World Example

The other day, I overheard two friends of mine discussing how one of them wanted to move her iPhoto collection off her packed Macbook Pro laptop. They were looking for the solution in the most obvious place, the iPhoto “Preferences” menu option. But they couldn't seem to find an option to point her collection's storage location to her external hard drive.

It took me a moment, but thankfully I was able to remember on the spot this seldom needed secret trick. (There was a little pressure on me)

Because Apple wanted to make iPhoto so easy for someone to use, it only makes sense they also want to protect their users from doing anything that would accidentally ruin their collection. And one quick way to do that would be for you to make iPhoto lose the connection with the correct library and database and not know how to fix it.

Thankfully Apple lets us change which photo library loads and where we store it, they just didn't go out of their way to make sure we would know how to do it!

My Very First Video Tutorial

So it occurred to me this is a situation a lot of iPhoto users will probably face at one time or another and would therefore be a perfect topic for my very first video tutorial on this website.

Oh, by the way, this technique will also work if you just want to move your library to a new folder location on your current drive.

Now go easy on me here! I haven't recorded my voice (on purpose) in a long time. And it certainly wasn't as easy as I had hoped! (I'm man enough to admit serious editing was involved)

Thank you so much!

Whether it’s all of our scanned or digital camera photos, or our huge collection of movies we seem to be downloading, it seems like we’re all running out of hard disc space. 

Hey, it’s Curtis, from Scan Your Entire Life, and if you use iPhoto for Mac, I would like to show you how to fix this problem. 

By default, iPhoto likes to store all of your photos in a single file called the iPhoto Library.  This is actually a good thing for most people.  It makes it easier; more of a hands-off approach to managing all of your photos. 

So what we’re going to be doing to free up hard disc space, is actually moving this iPhoto Library file to a separate hard drive. 

It’s very important that you have a backup copy of your iPhoto Library file, before you do what I am about to show you. Your photos are irreplaceable so please make a backup. 

So the first thing we need to do is make sure we close out iPhoto. I’m going to close out that window (Command-Q) or you can go to the iPhoto menu option and hit “Quit iPhoto.” 

Next, we need to find our iPhoto library, and for most people, you will find that on your hard drive, and in your user home folder. And then I will click here on my pictures folder. And you will see right here at the bottom is my iPhoto Library.  It looks like a single file but it’s actually a folder. And if you look over here, you will see that my iPhoto Library is 1.33 gigabytes, which is actually really small. You might find that your iPhoto Library is 20, 30, 40, 60 gigabytes – and that’s why your hard drive is so full. 

So even though my iPhoto library is really small, and you can see I have 205 gigabytes free on my hard drive, we’re going to pretend like my hard drive is actually empty, and we’re going to move this iPhoto Library to an external hard drive. 

Especially for laptop users, I wouldn’t really recommend having your iPhoto Library on an external hard drive for a very long time. It’s a good temporary solution but your best decision really is to replace your small hard drive with a larger one, and then use your external hard drive as a backup.  Because what this means is, anytime you load up iPhoto, you’re gonna have to make sure your external hard drive is plugged in. But, for certain circumstances, this might be the best solution for you right now. 

And it’s simply a matter of going over to your iPhoto Library, left clicking, and dragging the iPhoto Library over to your external hard drive. 

Because my test library is so small, it’s only going to take a couple minutes for it to finish copying.  But don’t be surprised if yours takes 20 minutes, 30, 40 – even an hour to copy depending on how large it is. 

[“Ding” sound effect] 

It’s important to note right now that we have 2 copies of our iPhoto Library. One is right here in the pictures folder, and another is in our external hard drive. If I move this down you can see both copies – here and right here.  This is important because we don’t want to delete the original version before we have tested out the new version to make sure everything is working correctly. 

So what I am going to do is go up to my pictures folder here, I’m gonna single click here where it says iPhoto Library – so that it’s highlighted with all blue. I’m going to right cursor over, and add word “old” to the end of the filename.  And I’ll show you in a second why that’s important. 

So what we wanna do now is boot into iPhoto, but we want to tell it to load from the new iPhoto Library and not from the one we just labeled “old.” And the way you do that, is you hold down the option key, keep it held down, and them move down to your dock, and click on iPhoto. And now a window will pop up and say, “What photo library do you want iPhoto to use?” And because we labeled the old iPhoto Library “old,” it’s a lot easier now to find the new one by clicking on the one that is obviously not labeled “old.” 

And for users with the latest iPhoto, you’ll be able to see a path description here on the bottom that will help validate that we have selected the correct external hard drive. 

So now we click on choose. And now iPhoto will launch using the newest iPhoto Library. 

And now we can quit out of iPhoto. I’m going to hit (Command-Q). 

So now it’s safe to delete the old iPhoto library. So I’m going to right-click on it, and then select “Move to Trash.” 

[Sound effect paper hitting trash can] 

Now if you are paranoid like me, maybe not Jack Nicholson in “As Good As It Gets” kind of paranoid, but just a good healthy case of paranoia, you will load up iPhoto one more time just to make sure everything is there and loads fine. I mean, I am just saying, this is your entire photo collection here! 

Everything seems good. Let’s empty that trash! 

[Sound effect paper being wadded up] 

So I hope you found this to be useful. Enjoy scanning the rest of your life! Cheers!

Epson quietly released a new version of their popular scanning software “Epson Scan” that comes bundled with their document and flatbed photo scanners. But, there’s already been confusion as to which scanners and operating systems it supports. Could it be possible that “Epson Scan 2” won’t even run in the latest versions of Microsoft Windows?

Epson V800 vs V850 — The 5 Differences and Which You Should Buy

So you’re ready to buy a very high-quality flatbed scanner to digitize your analog prints and film, but now you’re having a hard time deciding between the Epson Perfection V800 Photo and the Epson Perfection V850 Pro Photo Scanners.

Whether you or an avid hobby photographer, a true professional, or just want to get all the quality you can out of your prints and film, either one of these models is going to give you exceptional results. But, I want to help you feel confident you’re going to make the right choice.

Below, in plain English that will make it very easy to understand, I’ve written out and explained in detail, the 5 differences between the two models.

Are 99.9% of Your Photographs Just Not Important Enough To Save?
Are 99.9% of Your Photographs Just Not Important Enough To Save?

If this was your entire photo collection sitting in this trash can in the photo above, would this make you actually feel relief … or utter panic?

What if I added to this scenario. What if to the best of your knowledge, all of your photos sitting in the trash were already scanned and safely backed up on a couple of your hard drives.

Do you now feel relieved … or still utterly panicked?

From everyone I have talked to about this scenario, it seems safe for me to say that I believe the world is in somewhat of a divide whether it’s actually okay to throw away your prints and slides once they have been scanned and digitally preserved.

And for some, hopefully not too many, I am sure they would say it’s okay to throw away many if not most photos before they were scanned and preserved.

Yes. You heard me.

If You Don’t Add This to the Filename of Your Scanned Photos, You’ll Probably Hate Yourself Later
If You Don’t Add This to the Filename of Your Scanned Photos, You’ll Probably Hate Yourself Later

Whether you keep all of your scanned master (original) image files in folders on a hard drive, or you allow an image manager like Picasa, iPhoto or Aperture to manage them inside a library file, you will still be required to give each photo a filename.

It could be as simple and non-descriptive as “photo-1.jpg” or maybe even simple yet somewhat descriptive like “mom at the beach 1984.tif”.

But, it’s actually a very important part of the process of scanning photos, that if done with a little bit of forethought, can save you a lot of time and headache later.

My Inspiring Photo Scanning Progress Report for April 2012
My Inspiring Photo Scanning Progress Report for April 2012

Welcome to my third monthly progress report!

Last month I covered two complete months of scanning, but I learned that was just too much to talk about!

So this time is only one month and it’ll be a lot shorter.

What This Progress Report Is Really About:

Every month, I am posting a detailed report — just like this one — sharing with you how far I have come with my goal to scan and restore my entire 10,000+ family photo collection.

By doing so, I hope to inspire you to do the same!

In my first progress report, I set a goal for myself to do a little bit of work on my collection every single day. I shoot for about an hour a day which turns out to be about 30 scans a day. And I am going to record and detail each one of them so that you can learn from my transparency.

I don’t want to be “that guy” — a guy that tells you how you should scan your own photos but then sends all of my own to a scanning service to do the work for me.

How Quickly You Could Scan Your Entire Photo Collection — What I Discovered From My First Week of Scanning

So you have a closet with boxes full of old prints and slides that you are dying to have scanned and neatly organized on your computer.

The problem is, you’re worried about it either costing you way too much money to send it to a scanning service, or taking too much of your precious free time to scan them yourself on a flatbed scanner.

Does this sound EXACTLY like your dilemma?

I’d like to share with you my experience back scanning photos for the first week. If you want to make scanning your own photos fit into your busy and hectic life, I think my experience here might give you an idea how much time will be involved and how many photos you can easily get through.

The Best Way to Add a Description (Caption) to Your Scanned Photos
The Best Way to Add a Description (Caption) to Your Scanned Photos

Ah, there’s nothing quite like reading a great caption to go along with a special photograph. Sometimes they’re so effective, they just seal the emotional experience of being there—as if you were right there when that photograph was taken—even if you weren’t!

I think it’s so important that you record these “priceless” descriptions as soon as you can. Some of us might think we can remember all of the details. But face it, you probably won’t be able to. They’re fleeting. And even if you could, you and your memory aren’t going to be on this earth forever.

With prints, it was easy to record this information by writing the stories by hand on the back. But, now that we are wishing to move our prints, slides and negatives to a digital form in our computer, how do we easily add this information so that it can live with each master image file?

Use 1 of These Photo Managers If You Care About Your Photo Collection
Use 1 of These Photo Managers If You Care About Your Photo Collection

It was seriously a life changing day when I discovered the magic of a “non-destructive” photo managing program.

With “non-destructive” editing, all of the edits (enhancements) you make to your photographs are managed by the program itself. Your original photo remains untouched. It’s like having a guardian angel that protects your master images at all costs. It’s brilliant and is 100% absolutely indispensable to me now.

What Everybody Ought to Know When Naming Your Scanned Photos – Part 1

As my own scanned photo collection grows, it has really become obvious to me how thankful I am for the added attention I have been putting into the filenames I give to all of my scanned images.

When you’re scanning, it’s really easy to get into a “robotic” mindset where you are just trying to scan as many photos as possible in a sitting. So when you get to that blank field each time that asks you to type in a name for the file, it’s tempting to just quickly bang out a few descriptive words with little thought to how useful they will be to anyone later.

The DPI You Should Be Scanning Your Paper Photographs
The DPI You Should Be Scanning Your Paper Photographs

One of the most important decisions you face when scanning anything with your scanner is choosing what dpi (“dots per inch”) to scan with. And specifically for this post, what is the best dpi to use when scanning and archiving your 8×10″ and smaller paper photographic prints – which for most people, make up the majority of our pre-digital collection.

Making this decision was very challenging for me and certainly a huge part of my 8 year delay. The reason for this is that dpi is the critical variable in a fairly simple mathematical equation that will determine several important outcomes for your digital images.

How to Batch Change Titles and Descriptions in Photos for macOS

Have you ever wondered how to batch change the name and even the caption of multiple photos at a time in Photos for macOS, to the same information for all of them?

For example, you would want to do this if you had a group of photos all taken on the same day, during the same event, and you want to label them in a very similar way — if not the exact same way.

This is a very common need, and knowing how to do this in Photos is not as easy as it was in its predecessor, iPhoto.

Q&A: How Do I Add Photos Already On My Storage Drives Into Picasa? (Video)

A lot of people have photos stored in folders on their storage drives, so it makes sense that if you’ve never used a photo manager before, they can seem a little daunting as far as understanding how they interact with your photos already being stored on your computer.

In this Q&A style tutorial video, I answer a question I received from a reader of Scan Your Entire life on how Picasa fundamentally works to select which photos on your internal or external storage drives are used inside of the application.

Basically, I feel what’s in this video is the most important thing to understand in order to get the most out of Picasa.
