Why does iphoto reduce file size of pitcures when rotated?
Hello
I'd like to import photos from the camera directly into iphoto 09 to then be able to easily delete and rotate images. Once rotated i would like to export and save the good pitcures onto an EHD for storing and then delete them off iphoto to free space on my internal HD. (I normally keep all of my digital photos on an external hard drive in folders.... Each year has a folder, within that each month has a folder, etc. i like this method as it is organised.)
My question is: I have noticed that when a pitcure is rotated in iphoto the pitcure's file size reduces. Eg. When imported from a camera FINDER shows the file size of a jpeg pitcure to be 2.7MB. When i import it into iphoto the file size is still 2.7MB. But upon rotating the pitcure the file size reduces significantly to 1.7MB. Even when exported as "current" image, or drag and droppped, the file size is still the reduced 1.7MB
Why does iphoto reduce file sizes upon rotation?
Pitcures rotated in Preview do the same thing. I never had this issue with PC's. Perhaps my question should be how do i easily view and rotate pitcures with no loss of quality on a MAC?
I have done web searches with the question but I can't seem to find the answer... any help is greatly appreciate!
Thanks
