It appears to me that iPhoto is automatically enhancing my photos when it displays them--based on the fact that when I go into edit mode, the photo often appears completely different (and always worse).
Anyone else notice this?
No - and no one had posted it here
And iPhoto does not "automatically" enhance photos
Nopt sure at all waht you are seeing

Are you shooting Jpeg or Raw?
jpeg. I guess I'll have to wait until I notice it again, then capture some screen snaps. The photos are coming into iPhoto from a high resolution photo scannner.
Sounds like the thumbnail files need rebuilding. If you're using iPhoto 11 launch iPhoto with the Option+Command keys held down and, in the window that appears, select the second option:
It may take several attempts to fix them all.
If you're using iPhoto 09 or earlier select the 3rd and 4th items:
Again it may take more than once.
OT
Not sure why you see this problem as related to thumbnails. Can you explain?
What resolution? What color profile? If yu give it a bit does the edit mode image clear up? What version of iPhoto?

Larry,
Sorry I am so dense. The scanner is scanning photos at 300dpi and switches from b&w to color depending on what it senses the original is. The info window in iPhoto provides nothing but the length, width and file size. Imported file is a JPG.
I'll try to trap the next one that I see doing this and attach screen snaps.
Turn off the auto color/B&W switch - iPhoto only supports color (only RGB color) and sRGB is best
And note that 300 DPI is not a high resolution scan unless you have very large photos - with a 300 DPI scan you can only print hight quality up to the size of the original photo and good quality up to double the size
Thew length and width in pixels is the best information - DPI is meaningless for digital photos - if you scan a 4x6 photo at 300 DPI you get a 1200x1800 image - pretty low by todays standards - you need to be looking at teh pixel sizes fo the photos and the potential uses for them
In any case unless you are scanning very large photos then the digital image size is not a problem - for very large photos iPhoto can take a while to process and display the full resolution photo

Interpretation:
based on the fact that when I go into edit mode, the photo often appears completely differentRead that as the image in the edit mode was different than what you saw in the thumbnail/preview.
Thanks, I wasn't clear. If I double click (it is now at display size, not thumbnail) and select Info, I see the photo. If I click on Edit, the photo significantly changes (and is much worse). My working theory was that, when Info was selected, iPhoto was enhancing the photo, and when I went to Edit, it went to the original. The photos where I noticed it had just been scanned and had never been edited. The response from this forum was that is not an iPhoto feature. Next weekend, I will scan some more pictures and attempt to trap this phenomenon with screen snaps.
I really appreciate all your help, folks!
OK, trapped it. It only seems to occur with scanned B&W photos.
First pic is unedited, selected Info tab in iPhoto.
Second pic, taken after pressing the "edit" button (but with no editing):
They look different to me.
What colour profile are these images?
Sorry, I don't know what that means or how to tell. Willing to learn, though!
The Color Profile is - for the want of a phrase - the definition the computer uses to show you 'red' or 'blue'. There are many, many profiles, the ones iPhoto uses are RGB based, as that's what Cameras shoot in. If you have imported those images as a Greyscale setting on your scanner well then you will get unusual results.
Thank you, that was the hint I needed. I just got Aperture today and it shows the Profile Name: EPSON Gray - Gamma 2.2
From your comment above, that is the source of the variance. So, I'm not crazy (or at least one cannot base that judgment solely on this observation), and iPhoto is not broken. Appreciate your help.
