Download the Source Files
. Because the .psd files are to big for the Web I had to provide .jpg files for this tutorial
The idea for the image came during my visit in a Army Museum where I saw the ship model, from whom i made a few photos. Once the idea nested in my head, all i need to realize it, where the photos for the other elements. For that I took my Nikon D70 and went out to search the objects i need. Sometime to find and collect the proper photographs could take longer as the work on the image, but the time is worth. This Tutorial was made on a PC, with Photoshop 7 but it can be done also with CS or Photoshop 6. If you are on a Mac use Cmd instead of Ctrl and Opt instead of Alt for the shortcuts.
The first step is to Knock Out the roof. Open the " roof.jpg " file you will find in the "sources" folder. Because the contrast between roof and the sky in the image is good we will use the Magic Wand Tool (W), select the tool and click on the sky, then go Select-Similar to select the blue part of the image.
Now go Select-Inverse (Shift+Ctrl+I) to inverse the selection, go to Channel palette and click on the Save Selection as channel icon to create a new Alpha channel. Now go back to Layer palette and with the active selection, save the selection (Ctrl+S) then save and close the "roof.psd" file.
Create a new File, name it "Shipyard", set the size to A4 (or a size you can handle with, if this one is to big for your system), 300 pixels/inch, mode RGB color. Go Edit-Paste (Ctrl+V), name the layer "roof" and position the roof on the bottom of the image, then save the file as "shipyard.psd".
Open the "ship.psd " file from the folder "source" and use the Pen Tool (set opacity to 0 for a better view) to draw a path around the ship. When the path is closed go to path palette and Ctrl-click to make a selection from it. Now like before go to Channel palette and create a new Alpha channel from selection. Repeat this steps until the whole ship is selected.
Like with the other image before, go back to Layer palette and with the active selection, save the selection (Ctrl+S) then save and close the "ship.psd " file.
Open the "Shipyard.psd" file and go Edit-Paste (Ctrl+V), name the layer "ship" and drag it under the "roof" layer, with the layer selected go Edit-Transform-Rotate and rotate the ship a bit to the left to look like in the image.
