Zooming in on Parts of Photos
Created by: Doro Sensen

Sometimes you've got a photo with a great scenery in the background, and the person/object in the foreground is quite small, all the more so when you then have to reduce the photo in size to show it on a web page. One way to handle this would be to cut out the person/object to make it appear bigger, but then, this would destroy the nice background. This tutorial shows a way to both keep the full background and display the person/object that is important to you.

To follow this tutorial, you can download this photo and extract it into a folder. My mother took it of me at the Mondsee (Moon Lake) in Mondsee/Austria some years ago when we were visiting my sister's family. I scanned it with a resolution of 200 dpi so I got clear details which is important for this technique. I'm afraid this made the file quite big, though, even after resizing to 75% (84 KB); so if you have a photo of your own that you'd like to try this technique on you're very welcome to do so.
Open Mondsee.jpg from your download (or another photo of your choice) and duplicate it with Shift+D (Window || Duplicate) so you keep your original untouched.
Click on the Selection tool in your tool palette:
– Selection type = Circle
– Feather = 20
– Antialias = checked
Now draw a circle around the person on the bench in the foreground, taking the shoulder as the center of your circle. When you release the mouse button, the selection widens a bit because of the feathering.
Copy your selection with Ctrl+C (Edit || Copy) and paste it as a new layer with Ctrl+L (Edit || Paste || As a New Layer). Don't move the new layer yet.
Deselect with Ctrl+D (Selections || Select None).

Right-click on the background layer in your layer palette and choose "Promote to Layer" from the context menu. This layer is now your active layer.

Now go to Image || Resize:
– Percentage of Original = selected
– Width and Height = 40
– Resize Type = Smart size
– Resize All Layers = unchecked
– Maintain aspect ratio ... = checked
Double-click on the Crop tool in your tool palette to open the "Crop Area" dialog box:
– Select opaque area - merged = selected

Click on the "Crop Image" button in your Tool Options palette.

You can now click on the Zoom tool in your tool palette and then once on your image to have it in its real size. Your photo now has a size that's reasonable for showing on a web page.
Now click on the Mover tool in your tool palette and move the (round) zoom layer where you want it on your photo, usually on a part of the scenery that's not so interesting. I chose to put it in the bottom right corner of the image.
Depending on your object and the scenery you may want to reduce the zoom part a bit in size as well. For this, be sure that the zoom layer (the top layer in your layer palette) is active, and that "Resize All Layers" in the Resize dialog box is unchecked, then experiment with the percentage settings until the zoom part has the right size to fit into your scenery.
To distinguish your zoom part a bit more from the background, just give it a light shadow. Be sure that the Zoom layer is active, and go to Effects || 3D Effects || Drop Shadow:
– Vertical and Horizontal Offset = both 3
– Opacity = 60
– Blur = 4.7
– Color = Black

Well, that's it! Happy zooming :-))
