Jaimie has pointed out that you can tell it not to copy. There is an "Importing" section in the Preferences with a "Copy items to the iPhoto Library" option which is on by default. >and groups them into "events" by date There is a preference for how it splits photos into Events: "One event per day", "One event per week", "2-hour gaps", and "8-hour gaps". I assume the last two mean that it breaks into Events whereever there is a gap that long between photos, so if you take a photo every hour for a year, it will all be one event. -- Richard -- Please remember to mention me / in tapes you leave behind.

The increase in space usage only happens when you use iPhoto to modify an image. On modification, iPhoto copies the image, applies the mods and saves the modified version. The original is untouched. I keep my originals outside iPhoto, and tell iPhoto not to copy but reference them. This is done by iPhoto/Preferences/Advanced, unticking "copy items to the iPhoto Library". I let iPhoto do what it wishes otherwise. Again, pointing at my own photo library as an example - the folder structure on my NAS as 17gig, while iPhoto's storage in ~/Photos/iPhoto Library is 1.26gig. Note that since the originals are unaffected, if you do modify an image in iPhoto and want to do something with that outside iPhoto, you have to export it - which is as simple as drag and drop the pic (or pics, or event, or...) to a Finder folder. >>This `event' lark and dates - could you explain more? `Groups them into >>events by date' - erm?

The default is "one event per day", but the full set of options are "one event per week", "per day", "per 8 hours", "per 2 hours". It is arbitrary, but I suppose it's probably useful for people who have holiday snaps or birthday party snaps or whatever, and like to be spoon fed. The splitting into events also applies when you drag in a folder of photos, which can be rather annoying... but you can combine multiple events into one by drag and drop on the Events view page. The "Events" page in iPhoto's Library groups each event as one image, while the "Photos" page shows all the pictures you have, with horizontal separator bars between events. Events have no direct relationship with Albums, and are similarly arbitrary. Cheers - Jaimie -- I like my coffee how I like my women... frothing.

They seemed to use their cameras `all the time' as a casual part in their lives. (I was just some bloke who pulled funny faces at 'em in McDonalds) If your seemingly not valid assumption were true, you might have a point. Still, I've used my camera (35mm SLR) for multiple events over multiple days - in one case, one event covering four days interspersed with other explicit and different events*. And modern types seem to use their cameras /lots/ - without the limit of having to do the whole film thang (cost, time, bother), why not just dash off the shots?

Uhuh - a subtlty which isn't obvious... Actually, until now, I'd no idea how to get modifed forms of iPhoto images anywhere useful. > >>This `event' lark and dates - could you explain more? `Groups them into > >>events by date' - erm?
