I am new to photoshop and to the Adobe family. I have a question and hoping to get some help. I am trying to merge two photos and want the merge with actual sizes. One photograph is of a 9ft tree and another a picture of a 3 ft kid. The scales are different for the photos so how can i merge the photos so that they look same scale from their actual sizes.
Open one image (the background for example) then use File > Place to place the other image as a Smart Object.
The Smart Object can subsequently be transformed (cmd-T) repeatedly without accumulating image degradation.
If you need to see the underlying layer to better assess how much you need to scale you can temporarily change the Opacity of the Layer in the Layers Panel (or by hitting one number with the Move Tool (V) selected; the active Layer will then be set to that number times 10 in percent – so hitting »5« will set it to 50% Opacity).
Thank You. It works.
