i am digitising my photo collection using a nikon film scanner and photoshop on another mac. burning the bmps to cds which i bring home to my ibook.

i can import the bitmaps from the cd no probs into iphoto 2. each file is about 9MB.

Whenever I do any further editing in iphoto, the file size is massively increased. a simple crop and brightness adjustment has turned 9MB files into 20MB ones.

Anybody know what is going on here?

Thanks.

are you really using .BMP ? maybe iPhoto turns these into .TIFF which are possibly bigger ? don't know, just guessing.

no. file info displays all as .bmp

yep, that .bmp is your problem, BMP is an uncompressed format just like .TIFF, you should use JPEG if you want to keep the filesize down.
