Well I did a bit of reading about using a "reference database" and it sort of reminded me of the problem I have with iTunes. I hate how it creates multiple references and multiple files for music. So I chose to import my entire photo library into iP and live with the consequences. I hope I didn't make a mistake. It's difficult for an old PCer to relinquish control over files. I now need to find a suitable editing package. I'm not into a huge learning curve. I never inderstand how people are able to manipulate photos as well as they do using a mouse for creating layers ans such. Maybe I need to invest in a tablet. Any suggestions for a good editor under $100?
Photoshop Elements 6 is pretty neat, though it's got a bit of a learning curve. If you do family/group shots, though, it's got a fantastic "merge" feature, which allows you to take 2 or more shots, and select the best parts of each. For example, let's say you take 3 shots of a group (at the same time, with the same background, etc.). But, one person's blinking in photo 1, in photo 2 a different person is yawning, and in photo 3 a yet different person is looking away. Just by squiggling on their faces, PSE6 merges the best faces into a single photo. Very cool.
I use iPhoto for my basic edits (saturation, red eye, exposure, levels, tint, white balance, etc.) I also use iPhoto for noise reduction and sharpening, though PSE6 will do this better. I just can't usually be bothered for most of my shots.
Here's a trick that's pretty cool. Go to iPhoto preferences and set "double click the picture" to edit and set edit to "edit in full screen" I really like the feel of that environment. When you are in edit full screen, you can hit command-I to bring up the exif data, and type the letter "A" to bring up the adjustment tool pallet (hit the same key strokes to make them go away again). While in full screen view, go up to the menu, and pull down the "view" menu. At the bottom of the menu is "thumbnails" and then "always hide thumbnails".
This gives you a really max view of your pictures. If you move your mouse to the top, the thumbnails drop right down, and you can command-i and command-a the floating tool bars in and out as you need them. You can also use the left and right arrow keys to navigate the photos without the thumbnails.
Also try this: move your mouse up to the thumbnails and select a photo then, holding CTRL down, select another photo. Now you have a "2-up" view of photos. You can select more if you want -- 3, 4, 5 how many ever you need.
Then, in the "2-up" mode, select one of the photos so it's highlighted in yellow, and use the zoom slider at the bottom. Select the other photo and use the zoom slider. See how easy it is to compare two photos side by side?
I know there are better programs, but I just find iPhoto so light and easy to use. I just wish the would give people a manual. It would really find more fans, if people were given something so they could learn how to use it.
Good luck.
