Deleting duplicates in iPhoto - Effects on Time Machine Backup

I am new to Time Machine Backup. I have a query, (perhaps a silly one?)
Out of 4500 photos in my iPhoto, I have trashed 300 duplicates.
On my next backup in Time Machine on an Ext HD, will the deleted photos be also gone?
What about the duplicates that I originally stored in my Hard Drive under My Pictures? Are they also stand deleted?

MacBook Pro 17, Mac OS X (10.6.3), iPhone 3GS 32 GB

Hi blissalvacion,

Time Machine takes exact copies of your HD at the time the backup occurs. Here's an example:

05/05/10 @ 10:00am - 3500 photos
05/05/10 @ 11:00am - 3300 photos

So at some point in that hour block, you deleted 200 photos. All of sudden at 11:15am National Geographic calls and wants to pay you $1,000,000 for those 200 photos. If you click on the Time Machine icon in the menu bar at the top and select "Enter Time Machine" you can then view your HD as it looked at 10:00am and restore those deleted 200 photos.

The catch, unfortunately, is that with iPhoto the iPhoto Library is a container file (it's really a folder just doesn't look like one). So if the photos were deleted from within iPhoto you'd need to restore the entire iPhoto Library to how it looked at 10:00am. Based on the size of your iPhoto Library, the restore might take a little while.
