PSD/PSE file types & size.....

Nov 17, 2012 4:50 AM

Using the guided edit in Elements 9, I corrected a 1.8MB image for keystone distortion and when I saved the image, for some reason it saved as a PSD/PSE type file and also 'grew' from the original size to an enormous 82MB!! Similarly, when I converted an image to 'old style photo..vivid', it again saved as a PSD/PSE file and grew to 95MB!! Can you tell me what is happening here and more importantly, how to prevent it, as I can't use these massive file types for anything?

    I'm guessing the original photo was a jpeg?


    The psd file format uses little compression (depending on what's in the file), where as the jpeg file format uses a fair amount of compression depending on the quality setting and

    that's the difference in file sizes your seeing. Plus, if you have more than one layer, that will add to the file size of psd files.


    If you think you might be editing the photo some more you could try the Tiff format with LZW compression. (no data is lost)

    If your done with the photo, you could save as a jpeg with a quality of about 10.
