Few days back I came across a discussion on http:\\forums.adobe.com and the problem was regarding restricting crop ratio as same as that original Photograph. And this problem has a very simple solution. In Organizer as well as in Editor, there are options to restrict Crop ratio as per original ratio of the photograph OR Square OR Custom Ratio OR some standard ratios like 3*4, 4*6, 5*7 etc... Let's see how we can achieve this in Elements Organizer and then Editor application of Adobe Photoshop Elements !!!
In Organizer, when we opt Crop from Edit Panel on the right, as new window is opened with selected photograph. In this dialog there is a drop-down control named as 'Aspect Ratio'. Click and there are multiple options to control Crop Aspect-Ratio. If you want to keep the aspect ratio same as that of original, select 'Use Photo Ratio'. In case you don't want any restriction, just select 'Custom Ratio'.
Similarly this option is also available in Editor. Just have a look at highlighted area on top !!!
