Zoom Effect on Screenshots with GIMP - A Simple Tutorial
Creating a Zoomed Effect in GIMP: A Step-by-Step Guide
A comprehensive tutorial specifically tailored for GIMP beginners was lacking, prompting the creation of this guide. This article details a straightforward method for generating a zoomed effect, with explanations for each stage. Advanced GIMP users may find some steps elementary, but this is intended for those new to the software.
Step 1: Importing or Creating Your Screenshot
Begin by importing your desired screenshot into GIMP. This can be achieved by dragging and dropping the image, pasting it, or creating a new screenshot directly within GIMP by navigating to File > Create > Screenshot. For this example, a screenshot with dimensions of 1280 x 800 pixels will be used.
Step 2: Selecting the Area to Zoom
Utilize the Ellipse Select tool, ensuring it's set to "Replace current selection" under Tool Options. Draw a circular selection around the specific portion of the screenshot you wish to magnify.
Step 3: Copying and Pasting the Selection
Press Ctrl + C to copy the selected area, followed by Ctrl + V to paste it. This will create a new "Floating Selection" layer, visible in the Layers dialog (accessible by pressing Ctrl + L). Proceed to Layer > New Layer to establish a dedicated layer for the pasted circular image.
Step 4: Resizing the Original Layer
In the Layers dialog, select the original, bottom layer. Employ the Scale tool to adjust its size if necessary, particularly if it's too large for comfortable display in a blog post.
Step 5: Focusing on the New Layer
After resizing, toggle the visibility of the resized layer by clicking the eye icon next to it in the Layers dialog. This allows you to concentrate solely on the newly created layer.
Step 6: Expanding the Layer Size
Select the top, new layer and go to Layer > Layer to Image Size. This expands the layer's area to match the overall image dimensions.
Step 7: Creating the Selection Outline
Right-click on the same layer and choose Alpha to Selection. This action will select the outline of the circle.
Step 8: Adding the First Outline – Grey
To create the initial outline, go to Select > Grow. Type "1" (pixel) and click OK. Create a new layer, naming it "inner grey outline" if desired, and set the Layer Fill Type to Transparency.
Step 9: Filling the Outline with Grey
Select the Bucket Fill tool and choose a grey color from the color palette (e.g., #aca7a7). Fill the selected circle with this grey color. Lower the "inner grey outline" layer in the Layers dialog.
Step 10: Adding the Second Outline – White
Go to Select > Grow again, this time typing "2" for a thicker outline. Create another new layer, naming it "white outline" if you wish, and set the Layer Fill Type to Transparency.
Step 11: Filling the Outline with White
Swap the grey and background colors, ensuring white is the foreground color. Use the Bucket Fill tool to fill the circle with white. Lower the "white outline" layer so it sits directly above the grey outline layer.
Step 12: Adding the Third Outline – Outer Grey
Create a new transparent layer ("outer grey outline" is a suitable name). Grow the selection by 1 pixel (Select > Grow). Swap the colors to make grey the foreground color, and fill the selection with grey. Position this layer below the white outline layer and above the original background layer.
Step 13: Applying a Drop Shadow
With the selection still active, apply a drop shadow effect by navigating to Filters > Light and Shadow > Drop Shadow. The default values are generally suitable; however, uncheck Allow Resizing before clicking OK.
Step 14: Creating an Inner Glow
Select the Pasted Layer (the zoomed screenshot layer). Right-click and choose Alpha to Selection. Then, go to Select > To Path.
Step 15: Feathering the Selection
Create a new transparent layer ("lens feather" is optional). Go to Select > Feather and enter "50" (pixels) in the dialog box.
Step 16: Inverting and Filling the Selection
Go to Select > Invert to apply the following action to the area outside the circle. Swap the colors so white is the foreground color and fill the selection with white. De-select by going to Select > None. Then, go to Select > From Path, then Select > Invert and press the Delete button.
Step 17: Adding a Shine Effect
Right-click on the Pasted Layer and choose Alpha to Selection. Use the Ellipse Select tool, selecting the 4th mode ("Intersect with the current selection") and draw a circle over the left side of the zoomed image. Create a new transparent layer ("shine" is optional) and fill the selection with white. Reduce the layer opacity to approximately 10%. Go to Select > None.
Step 18: Final Adjustments and Merging Layers
If you wish to reposition the zoomed image, you can merge the layers above the background layer (Layer > Merge Down). Toggle the visibility of the background layer to ensure it's visible.
This completes the process. Experiment with the feather value to achieve different effects.
