Hi Guys,

Recently I just realised that if I open an image in PS and resize it using Image > Image Size, it resizes the entire document/canvas plus the image itself. However, if I create a new document and place/copy and paste an image within this new document as a new layer and attempt to resize it, it does nothing. Yet, I can resize using the transform tool. Another observation was that the first method reduced the resolution whereas the second method doesn't. I am interested to know why this occurs and is it possible to resize the image on a new layer within an existing document using Image > Image Size?

Thanks in advance.
