Cropping

When I import my RAW pics into Aperture, I crop them and then make adjustments. Aperture then automatically converts it to TIFF format. I notice that after the crop my pics, the file sizes become much smaller. Why is that? Does this mean the quality is degraded and I can no longer print it at a big size? Thanks for the help in advance.

You must be exporting your files, otherwise Aperture doesn't save them in TIFF format. Regardless, when save your file as a TIFF Aperture is saving not the original RAW but the version that is edited. So if you have cropped the photo then the file size will be smaller since it's only saving the cropped portion of the image. However, keep in mind that TIFF files are larger than RAW files so the file sizing won't be a 1:1 with the crop. In other words, cropping an image by 50% won't yield a 50% smaller file.

Actually, cropping is rather more difficult than we may believe at first sight. The printability (if you catch my drift) is not only dependant on the file size, but also on the actual pixel size and count. I'm a Lightroom user and am not sure how Aperture fixes the crop size

 

It's too long a story to just dot down here, but google on "photoshop print format" and "pixels and print format" and more like that and you'll find some interesting answers.

When you take a bite out of a biscuit, ask yourself, does it get bigger, or does it get smaller?
